German startup Rocket Factory Augsburg (RFA) just put the brakes on its first launch.
While testing its RFA One rocket on the launch pad at the U.K.'s SaxaVord Spaceport on the Shetland Islands in Scotland, the company found "an issue with the vehicle that requires further investigation," RFA wrote on X on Wednesday (July 28). Previously, the launch had been expected to happen in August or September, but RFA did not disclose a new launch date.
RFA did not disclose the nature of the issue, but said it would de-stack the staged rocket and that it would provide more details as the investigation continues. The situation means that the U.K. will need to wait at least a few more weeks to attempt its first-ever vertical launch from the region, amid global constraints in launch capacity and calls for increased European spaceflight autonomy.
RFA One, a smaller rocket designed to launch smaller satellites, is a three-stage rocket that will eventually include a reusable first stage in an effort to push down cost and to increase launch cadence. It will target a range of orbits, with examples including geosynchronous (where a satellite can constantly look at one area of the Earth), polar (allowing satellites to scan the whole Earth, as the planet orbits underneath) or sun-synchronous (which gives consistent lighting conditions.)
It's common for new rockets to encounter issues during development, including in later stages such as integrated pad testing or even during the first launch, because spaceflight is inherently hard. That said, there is more pressure on startup launching companies than ever to achieve their goals quickly, for commercial and defense reasons.

Rockets are in high global demand in large part due to constantly launching satellite batches for large satellite constellations, most especially SpaceX Starlink, and planned orbital data centers. Simultaneously, the U.S. Department of Defense is asking companies to launch more often for security missions, such as the quick-turnaround VICTUS HAZE mission that Rocket Lab launched in June only 16 hours and 42 minutes after receiving the military's request.
Conflicts in Ukraine and Iran and other defense activities, meanwhile, have pushed other countries into more sovereign launch work that is accelerating already ongoing spaceport construction, in jurisdictions such as the U.K., Europe and Canada.
RFA has been trying to position itself as one of the leading new companies in Europe, on the back of receiving a spaceflight operator license in January, from the UK Civil Aviation Authority, for the SaxaVord spaceport launch. Meanwhile, SaxaVord is working to become an alternative to older, busier launch ports (especially Kourou's Guiana Space Centre, a popular location for high-profile launches such as the James Webb Space Telescope.)
"This is a groundbreaking moment for RFA and for Europe's space industry," Jörn Spurmann, RFA chief commercial officer, said in a statement released shortly after his company obtained the license. "Securing the first-ever launch license outside the European Space Agency's established site in Kourou is not just a regulatory milestone—it's a powerful endorsement of our technical excellence and a turning point for European space innovation."
Rumors are also abounding in the industry that the popular SpaceX Falcon 9 rocket, which companies worldwide use for rideshare missions, might not be accepting slots for its popular Transporter series beyond 2028 or 2029. If this happens, the demand in launch capacity transferring from SpaceX might lead to more opportunities for companies such as Rocket Lab and RFA One, assuming more rockets are ready in time.
SpaceX has sent yet another batch of its Starlink internet satellites into orbit.
A Falcon 9 rocket carrying 24 of the broadband spacecraft lifted off from California's Vandenberg Space Force Base on Friday (July 31) at 11:08p.m. EDT (8:08 p.m. local time; 0308 GMT on Aug. 1).
The rocket's first stage came back to Earth as planned 8.5 minutes later, touching down in the Pacific Ocean atop the SpaceX droneship "Of Course I Still Love You." It was the 26th mission for this particular booster, which is designated B1081.
The 24 Starlink satellites were deployed into low Earth orbit (LEO) 61.5 minutes after liftoff as planned, SpaceX confirmed via X.
They're joining more than 10,800 other spacecraft in the Starlink megaconstellation, by far the largest satellite network ever assembled.

SpaceX has now launched 89 Falcon 9 missions in 2026, 69 of which have been dedicated Starlink flights.
The company also has three other liftoffs under its belt this year — one launch of its powerful Falcon Heavy vehicle and two test flights of Starship, the fully reusable megarocket SpaceX is developing to help humanity settle the moon and Mars, among other tasks.
We just got an amazing new view of SpaceX's Starship vehicle, thanks to one of the company's next-gen Starlink satellites.
Starship, the biggest and most powerful rocket ever built, launched on its 13th test flight from South Texas last Friday (July 24). The suborbital jaunt was similar in many respects to past Starship test missions, with one big exception: This time, the vehicle deployed a batch of functional, next-gen Starlink internet satellites into space.
Six of those "Starlink V3" spacecraft carried cameras, so that SpaceX could get good views of the heat shield on Starship's upper stage, which is known as Starship, or simply Ship. The satellites did that job and more, capturing amazing views of Ship as it cruised away from them high above Earth.

SpaceX shared one such view on X Friday evening (July 31) — a 65-second video that stitches together imagery taken by four different cameras on a single Starlink V3 satellite.
The video starts with an up-close view of the shiny, 171-foot-tall (52 meters) Ship. We see more of the vehicle as the footage rolls and the two spacecraft get farther and farther apart. Toward the end, we see Ship in its entirety, and we get a sense of its activity; three of its six Raptor engines are firing, and small puffs of white vapor indicate that the vehicle is engaging its fine-tuning reaction control thrusters.
Like all Starship test missions to date, Flight 13 targeted a suborbital trajectory. So the 20 Starlink V3 satellites, the first ever to reach space, did not stay up for long; they came back down to Earth about 20 minutes after deploying into the final frontier.
Their successors will get higher — and there will be many of them. According to a filing with the U.S. Federal Communications Commission, SpaceX wants to operate a megaconstellation of 100,000 Starlink V3 satellites.
Starship will be key to building and maintaining this constellation, which will require many launches of the brawny, fully reusable rocket. (SpaceX currently operates a constellation of nearly 11,000 Starlink satellites, but those V2 craft are considerably smaller than the 4,400-pound V3 iteration.)

Ship seems to have checked all of its boxes on Flight 13. After deploying the satellites and successfully reigniting one of its Raptors in space, it splashed down on target in the Indian Ocean off the coast of Western Australia about 65 minutes after liftoff.
The vehicle survived its harrowing return trip through Earth's atmosphere in one piece and remains intact today, as far as we know; SpaceX recently shared a photo of the vehicle bobbing in the Indian Ocean five days after splashdown.
But Starship's giant first-stage booster, known as Super Heavy, had a few issues on Flight 13. Its landing burn employed only five of a planned 13 Raptor engines, for example, and the booster hit the waters of the Gulf of Mexico at a higher velocity than intended. (Super Heavy has a total of 33 Raptors, all of which fire at liftoff.)
Starship remains in the development phase, but SpaceX wants to get the megarocket operational soon. It's slated to fly on NASA's Artemis III astronaut mission to low Earth orbit in mid-2027 and to land a crew near the moon's south pole on Artemis IV in late 2028.
NASA is planning to send two maneuverable probes to lunar orbit in order to learn how spacecraft are affected by the complex gravitational environment near the moon.
The mission, known as CAPSTONE 02, is currently aiming to launch in 2027. It will see the two probes maneuver in close proximity to one another and fly in "formation" so mission operators can better understand the gravitational effects spacecraft experience in cislunar space. This area of space is under the influence of both Earth's gravity and the moon's, meaning spacecraft operating there will have to navigate what are known as "three-body orbits."
While testing spacecraft maneuverability in these complex orbits, CAPSTONE 02 will also study communication and navigation systems that will be used in NASA's planned Artemis missions of lunar exploration and moon base construction. "This mission represents an important step in the maturation of cislunar capabilities," said NASA's Sean Fuller, Moon Base CAPSTONE manager, in an agency statement. "CAPSTONE 02 lays the foundation for lunar infrastructure and commercial services that support Artemis, Moon Base, and future missions to deep space."
The two CAPSTONE 02 probes are being built by Terran Orbital Systems, Inc. Once in space, they will alternate jobs while flying in formation, switching between what NASA calls "chaser" and "target" roles.
The spacecraft pair will use celestial navigation, optical sensors and data collected by telescopes on the ground during these maneuvers. This is similar to how NASA will use a variety of data to help its Orion spacecraft meet up with a lunar lander en route to the moon.
"Transporting crew to the lunar surface from cislunar orbit depends on knowing how well navigation systems will perform during these operations. Since these conditions can't be fully recreated on Earth, they must be tested in space," NASA wrote in its statement outlining the CAPSTONE 02 mission.

As its name implies, this will be the second mission under NASA's CAPSTONE program, or Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment. The first CAPSTONE probe launched in 2022 and operated for four years before NASA officially concluded its mission in June 2026.
That microwave-oven-sized CAPSTONE spacecraft tested communications tech and became the first spacecraft to test three-body orbits around the moon, according to a NASA statement.
CAPSTONE was tested in what is known as a near rectilinear halo orbit. This is a fairly gravitationally stable orbit, thanks to the nearly equal pulls of both Earth's gravity and the moon's.
It was Lucky 13 for SpaceX, as new videos show just how much work came into getting the latest flight of Starship’s upper stage softly down into the ocean.
After Starship made its 13th launch on Friday (July 24) from SpaceX's Starbase site in South Texas, the upper stage achieved all major milestones: putting 20 next-gen Starlink satellites aloft to watch it go, reigniting a Raptor engine in space, and then the soft splashdown off the coast of Western Australia.
While the lower stage of Starship faced engine issues, fresh video shows some incredible views of the successful upper stage. Starlink satellites, ferrying signal from a buoy in the Indian Ocean, helped create a video on X showing the 171-foot (52-meter) upper stage roaring above the water, then generating steam as the engines swiveled to make a gentle splashdown.

Getting down that way was no easy feat, as SpaceX posted another video on Tuesday (July 28) showing Starship swaying dramatically in midair to achieve a near-vertical orientation above the water. If you don’t mind a bit of vertigo, SpaceX also provided an on-ship view of the splashdown, complete with dramatic swings and ocean steam.
The upper stage's ocean arrival was so soft, in fact, that days after launch on July 28 the 171-foot (52-meter) stage was reported as still afloat in the Indian Ocean, SpaceX said on X, adding that its Starship recovery team is continuing to gather imagery of the vehicle at sea.

Starship's Version 3 (which flew on Friday) is a 408-foot-tall stacked system including the Super Heavy booster and the upper stage, also known as Starship (or Ship). SpaceX aims to make this system rapidly reusable for applications ranging from astronaut moon missions to launching even more powerful and larger Starlinks.
That said, SpaceX still needs to notch some goals ahead of its expected participation for docking during the Artemis III astronaut mission scheduled for next year, and to possibly bring astronauts to the moon's surface during Artemis IV.
And Ars Technica (quoting experts) recently raised concerns about the Starship heatshield, noting more changes will be required for reusability.
A new Federal Aviation Administration (FAA) proposal says the agency wants to speed up commercial space licensing for rocket launches and spacecraft re-entries by removing "unnecessary" environmental regulations.
The proposed FAA rule, released yesterday (July 29), has a 30-day period for comment and if approved, would apply to rocket launches, re-entering spacecraft, and the sites at which launches and re-entries take place. The FAA proposes to "waive requirements of laws of the U.S. for a license or permit, after consultation with the head of the appropriate executive agency, when the requirement is not necessary to protect the public health and safety, safety of property, and national security and foreign policy interests of the United States," the text of the proposal reads, in part.
The Department of Transportation stated that the proposal, if implemented, would allow the agency to waive what it calls "unnecessary environmental laws and regulations" that it claims are "slowing American innovation." However, the proposal will still require the FAA to ensure that launches do not impede on public health and safety, or U.S. national security or foreign policy.
To do so, the FAA plans to remove 13 federal laws from applying to "certain commercial space licenses and permits", with examples including the National Environmental Policy Act, the Endangered Species Act, parts of the Clean Water Act, the Clean Air Act, and the National Historic Preservation Act.
The proposal takes place as the United States is seeing unprecedented demand on its limited spaceports for commercial launches, fueled by broadband satellite constellations like SpaceX Starlink, as well as emergent orbital data centers. Earlier this month, the U.S. government proposed moving some launch operations offshore to ease the demand backlog. More rocket launches, according to peer-reviewed research, could cause environmental issues.
The proposal also appears to build on two recent Trump administration executive orders. The first, from December 2025, saw the administration aim to redirect a wide swath of space policy — including boosting the number of rocket launches and landings. (These already were at unprecedented levels last year, mostly on the back of SpaceX.) The second one, in August, focused on streamlining launch licensing and accelerating spaceport construction.

Meanwhile, SpaceX is trying to procure a federal land swap in south Texas, mostly for Starship operations, but its proposal prompted an emergency injunction last week filed by a coalition of conservation and tribal groups.
The groups allege this proposal would degrade the Lower Rio Grande Valley National Wildlife Refuge — from which the land is coming from — with legal implications as well, but the court has not yet ruled on a lawsuit the coalition raised in June.
Things aren't going so well for NASA's latest satellite rescue mission.
NASA launched the Swift Boost mission on July 3, sending a specialized spacecraft to low Earth orbit on a Northrop Grumman air-launched Pegasus XL rocket. The spacecraft is called LINK and was built by Arizona-based Katalyst Space Technologies. LINK was sent to orbit to try and link up with NASA's Swift observatory, a highly successful scientific satellite designed to search for gamma-ray bursts, some of the most energetic events in the universe.
But it looks like just a few weeks after launch, LINK is experiencing some issues. "Katalyst's LINK servicing spacecraft experienced issues with attitude control, causing the spacecraft to spin and resulting in sporadic communications," NASA wrote in an update on Tuesday (July 28). Despite the malfunction, however, the space agency says the rest of the spacecraft is functioning normally and remains in otherwise good health.
According to preliminary analysis of the issue, two of the LINK spacecraft's three reaction wheels are not operating. In addition, there is "some loss of functionality" in LINK's cold gas thruster system.
The failure with the LINK spacecraft's reaction wheel is slightly ironic, given that the Swift observatory itself once had issues with its own reaction wheels. In 2022, NASA placed the observatory in safe mode when one of its reaction wheels caused minor issues with the spacecraft's movements.

Mission teams will now try to use the spacecraft's electric propulsion system to stop the spinning and regain control. If that can be done, NASA and Katalyst will then have to evaluate if the mission can proceed as planned.
Swift's orbit has been decaying for years, and the observatory is unable to boost its orbit on its own. Thus, LINK was designed to meet up with Swift in low Earth orbit and spend some time studying the observatory to determine how best to grab onto it with three robotic arms. Once it has linked up with Swift, LINK should be able to use its own thrusters to boost the observatory to a higher orbit and extend Swift's life.

The Swift observatory, officially known as the Neil Gehrels Swift Observatory, was launched in 2004 at a cost of $250 million. The Swift Boost mission only cost NASA $30 million.
Over the last 22 years, Swift has been searching the sky for gamma-ray bursts and other high-energy astrophysics phenomena in the cosmos. In 2022, the observatory spotted a gamma-ray burst nicknamed the "BOAT," short for Brightest of All Time. At the time of discovery, it was the most powerful space explosion ever seen.
SpaceX launched a secret reconnaissance mission for the U.S. government early on Thursday morning (July 30).
A Falcon 9 rocket lifted off from Florida's Cape Canaveral Space Force Station on Thursday, kicking off the mission for the U.S. National Reconnaissance Office (NRO) called NROL-95.
The launch occurred at 3:10 a.m. EDT (0710 GMT).

We know very little about NROL-95; the NRO, which operates the country's fleet of spy satellites, has provided no details about the payload or its activities.
The agency has revealed the NROL-95 mission patch. It depicts a snarling ferret with a nighttime sky in the background and the words "We are the Champions" on the emblem's lower border.
"The ferret, a clever creature, embodies agility and resilience — key traits for exploration. Its confident grin and bright eyes reflect a spirit of victory in a realm where determination meets adventure," NRO officials said in an NROL-95 mission description.
"The bold phrase 'We are the Champions' encapsulates the camaraderie and pride shared among those on this purposeful mission," they added.

NROL-95 was the fourth NRO launch of 2026. The other three — NROL-105 in January, NROL-172 in May and NROL-179 in June — also flew aboard Falcon 9s, but from Vandenberg Space Force Base in California.
Those three other missions were devoted to building out the NRO's "proliferated architecture" constellation, which will consist of hundreds of relatively small, cost-efficient reconnaissance satellites in Earth orbit.
On Thursday, the Falcon 9's first stage came back to Earth for a landing at Cape Canaveral about 8.5 minutes after liftoff. It was the seventh mission for this particular booster, according to a SpaceX mission description.
SpaceX cut off its livestream shortly thereafter, at the request of the agency.

SpaceX's Starship V3 looks absolutely seaworthy in this new photo taken days after its most recent flight test.
What is it?
SpaceX launched its Starship vehicle on July 24, sending the 408-foot-tall (124-meter) Starship Version 3 (V3) rocket on a suborbital trajectory that saw the rocket's upper stage make its softest splashdown yet.
In fact, the landing was so smooth that Starship is still floating off the coast of Western Australia. SpaceX shared the photo of Starship on Tuesday (July 28), posting on X that the vehicle is "still afloat in the Indian Ocean."
The scorch-streaked 171-foot (52-meter) Starship upper stage resembles an orca or a submarine in the photo, resting mostly out of the water.
Why is it incredible?
It wasn't just the splashdown that was so stunning. Video taken from aboard Starship and from the Starlink satellites that were deployed alongside the upper stage during Flight Test 13 truly looks like the stuff of sci-fi.
Starship, which consists of SpaceX's Super Heavy booster and the somewhat-confusingly-named upper stage known as Starship (or Ship), is designed to be rapidly reusable. That means, if all goes according to plan, SpaceX will eventually be able to land both stages and have them refueled, inspected and ready for flight again in a matter of days.
But there are still major hurdles to cross before that goal is ever reached. SpaceX will have to figure out how to make Starship's heatshield more durable and reusable, a feat some experts call a "dead-end for all missions that require full and rapid reusability," according to Ars Technica.
Nevertheless, having a fully intact second stage rocket floating on the ocean four days after a flight test is quite a feat.
A new Airbus passenger jet completed an ultra-long test flight between Australia and France lasting more than 24 hours—paving the way for the world’s longest nonstop commercial flights starting up next year.
The Airbus A350-1000ULR was developed specifically for Qantas Airways’ planned nonstop flights between Sydney and either New York or London. The Australian airline has ordered a dozen of the new airliners for its Project Sunrise routes that aim to start offering tickets for sale in 2027.
The aircraft had been doing initial test flights near the Airbus facilities in Toulouse, France, with a small team of test pilots and test engineers before conducting its first ultra long-haul test flight last week. After taking off from Toulouse on July 23, it flew for 19 hours and 13 minutes before landing in Melbourne, Australia, on July 24.
SpaceX launched 24 more satellites for its Starlink network on Saturday (July 25), a day after demonstrating it could do the same on its next-gen rocket.
The launch marked the eighth flight of the Falcon's 9 first stage (Booster 1100), which touched down on the "Of Course I Still Love You" droneship, stationed in the Pacific Ocean.
The successful launch raised the total number of active Starlink satellites to 10,865, according to satellite tracker Jonathan McDowell. That number had been 20 units higher for about 20 minutes on Friday, when SpaceX conducted a deployment and operations trial during the 13th test flight of its Starship launch vehicle.
The Starship test was planned to be short-lived but was successful in providing data to support NASA's decision to fly Starlink systems on its Artemis III crewed mission to LEO, which is scheduled to fly next year.
Saturday's launch was SpaceX's 87th Falcon 9 mission of the year.
SpaceX launched the world's most powerful rocket on a critical 13th test flight late Friday, but there was no triskaidekaphobia on this mission.
The July 24 test launch, Space's Starship Flight 13 mission, sent a towering rocket the size of a 40-story skyscraper into space from South Texas, returned its massive Booster to Earth, and then — in a feat perhaps none saw coming — gently landed its Starship upper stage in the Indian Ocean, where it tipped over to float belly up on the sea.
"Starship is intact, floating in the ocean and transmitting telemetry!" SpaceX CEO Elon Musk wrote on X.

"That is a first," SpaceX spokesperson Dan Huot added in live commentary as a drone beamed stunning views of Starship bobbing in the waves. "That is the softest splashdown we have ever had with Starship in the Indian Ocean."
The splashdown capped what appeared to be a mostly successful test flight of SpaceX's biggest Starship ever. With a mighty roar, Starship Flight 13 lifted off from SpaceX's Starbase, Texas launch site at 6:51 p.m. EDT (2251 GMT) on a test flight that lasted just over one hour.
It was only the second flight of the company's new Starship Version 3 design, or V3, and SpaceX was hoping for a better outing than its first attempt in May. During that previous test, the Starship Flight 12 mission, the massive Super Heavy first-stage Booster suffered engine problems after stage separation and failed to make a water landing in the Gulf of Mexico. It crashed instead.
Lucky Flight 13
Friday's Starship Flight 13 mission fared a bit better.
SpaceX initially tried to launch Flight 13 on July 16, but the rocket aborted the try at the last second due to engine issues. SpaceX replaced some first-stage Raptor engines in time for a July 23 launch attempt, but waved off due to weather, setting the stage for Friday's successful liftoff.
Minutes into the flight, the Super Heavy Booster successfully separated from its Ship upper stage, aced a flip maneuver and returned to Earth. There was a problem during the landing burn. Only five engines appeared to fire when 13 were required to slow the Booster to landing speed. It hit the Gulf waters harder than planned, its camera views cutting out.
"It didn't look like we lit all 13 engines that we were planning for that initial landing burn," Huot said. "We were targeting a softer splashdown and, as you saw, it came in with quite a bit of velocity."

Starlink V3 makes a debut
Starship is intact, floating in the ocean...'
- Elon Musk, SpaceX CEO
Despite the Booster's rough landing, there were clear successes on Starship Flight 13.
While sailing on its suborbital trajectory, Flight 13's Ship upper stage deployed 20 next-generation Starlink Version 3 internet satellites — large, flat satellites equipped with laser communications links and expansive solar arrays that will replace SpaceX's current Starlink internet megaconstellation.
Starship is designed to launch 60 Starlink V3 satellites at a time, spitting them out through a slit-like payload bay door like a giant PEZ candy dispenser. All 20 Starlink V3 satellites deployed smoothly, with the last two switching on flashlights and looking back at their Ship carrier before floating off into orbital darkness. The satellites did not stay in space. They fell to Earth and burned up (by design) due to their suborbital flight path.
The Ship upper stage (which SpaceX also refers to as Starship) then reignited one of its six Raptor engines to test a critical engine relight capability that will allow future Starships to enter and leave orbit. The burn went off without a hitch — a milestone since SpaceX had not always performed the burn if a test didn't go smoothly.
Then it was time for reentry, with cameras beaming back stunning views of Starship wrapped in super-hot plasma as it fell back to Earth. The spacecraft executed a three-engine burn to flip over into a vertical landing position, but did shift down to two engines, then one before it toppled over to rest on the waves.
The sight of a floating Starship triggered a cacophony of cheers from SpaceX teams at Starbase and its Hawthorne, California rocket factory in the company's livestream. After all, Starships usually explode after they tip over.
"This is just the first time we've put a Starship into the water," SpaceX's Dan Huot said during live commentary. He called it SpaceX's "softest splashdown" ever. "This is a dream scenario for this team that's trying to get this heat shield data."

The heat shield isn't the only thing SpaceX's recovery team will be looking at.
Live views from Starship showed its six engines intact along with its flaps and other systems. Teams will be poring over what they can retrieve from the sea to help improve future Starship upgrades.
SpaceX is developing Starship to be a fully reusable launch system, a 407-foot-tall (124 meters) megarocket capable of taking Starlink fleets to orbit as easily as it lands NASA astronauts on the moon. That part is key.
NASA has tapped SpaceX's Starship to land its Artemis IV astronauts on the moon in 2028, but SpaceX has yet to ever complete an entire Earth orbit with Starship after 13 test flights and three years of launches. It's been a decade since Elon Musk first unveiled what SpaceX now calls Starship during a 2016 speech.

Over the next two years, SpaceX must not only send a Starship into orbit. The company also aims to return a Ship to Earth to catch it in the "chopsticks" of its Mechazilla launch pad at Starbase. (The company has already done so with its Super Heavy Booster stages.)
SpaceX also must successfully demonstrate in-space Starship refueling, complete an orbital tanker version of Starship, and finish a crewed lander version complete with a life support system that can keep astronauts alive on the moon. That's a lot on the Starship to-do list and NASA is watching.
"Congrats on getting Flight 13 underway," NASA Administrator Jared Isaacman wrote on X after the launch. "Excited for what will be learned from this mission. When Starship comes online, its capabilities will be game-changing, not least of which will be ensuring we never give up the Moon again!" In a lunar coincidence, Friday's launch coincided with the 57th anniversary of theApollo 11astronauts' return to Earth after their historic moon landing flight.
But for now, SpaceX is clearly celebrating.
"I'm a little over the moon right now," Huot said. "Wow. Lucky number 13. Hell of a great day for Starship."

NASA’s X-59 test pilot Mike Lippert stands in front of the agency’s X-59 quiet supersonic research aircraft at NASA’s Armstrong Flight Research Center in Edwards, California, on Wednesday, June 24, 2026.
NASA/Carla Escamilla
NASA added a new X-59 test pilot to support the agency’s Quesst mission: Mike Lippert, a research test pilot based at NASA’s Armstrong Flight Research Center in Edwards, California.
“This fulfills a lifelong dream of conducting airborne research and experimental flight test for NASA in the high desert — contributing to humankind’s understanding of the science of flight and the nature of the world around us,” Lippert said.
Lippert will fly the X-59, along with the F-15 and F-18 support aircraft to monitor the quiet supersonic X-plane when it’s in the air. He joins Nils Larson and Jim “Clue” Less, who have been flying the X-59 since its first flight in October 2025.
A South Carolina native, Lippert served 20 years with the U.S. Marine Corps before retiring last year as a lieutenant colonel. Like his fellow test pilots, he boasts an impressive flight resume, including logging more than 2,600 hours of flight time in 60 different types of aircraft.
Lippert said he finds test pilot work especially rewarding.
“For me, the joy of taking part in experimental flight test and airborne research is the experience of discovery and learning something new every day,” he said. “It is incredibly rewarding to be part of a team solving complex problems and venturing into the unknown, together.”
Lippert spent the majority of his career flying the AV-8B Harrier operationally and serving as a test pilot in the F-35 program. He is also an aerospace engineer, earning a bachelor’s degree from the United States Naval Academy in Annapolis, Maryland, and a Master of Science in flight test engineering from the U.S. Air Force Test Pilot School at Edwards Air Force Base in California. Additionally, he earned a Master of Science in systems engineering from the Naval Postgraduate School in Monterey, California.
Lippert is currently pursuing a doctoral degree in aerospace engineering at the University of Alabama Graduate School in Tuscaloosa, where his research focuses on high-speed gas dynamics, including supersonic and hypersonic fluid mechanics — complementing his work on the Quesst mission.
Lippert is busy preparing for his role at NASA by flying training flights on support aircraft and spending time in the X-59 simulator. He is expected to begin flying the X-59 later this summer.
Michael T. Lippert is a research test pilot at NASA’s Armstrong Flight Research Center in Edwards, California. He is assigned to fly the agency’s X-59 quiet supersonic research aircraft, along with the F-15 and F/A-18 support aircraft, and to support NASA’s advanced air mobility research projects.
Experience
Prior to joining NASA in 2026, Lippert served 20 years in the U.S. Marine Corps before retiring as a lieutenant colonel in 2025. He was a flight instructor at Naval Air Station Kingsville in Texas, where he trained U.S. Navy and Marine Corps officers in tactical jet aircraft. He has more than 2,600 hours of flight experience in 60 types of aircraft.
The bulk of his career was spent flying the AV-8B Harrier operationally and serving as a test pilot in the F-35 program. During his last two assignments, he served as the chief test pilot of Marine Operational Test and Evaluation Squadron One at Marine Corps Air Station Yuma in Arizona, and as the government flight test director of the F-35 Integrated Test Force at Naval Air Station Patuxent River in Maryland.
Education
Lippert earned a bachelor’s degree in aerospace engineering in 2005 from the United States Naval Academy in Annapolis, Maryland, and a Master of Science in flight test engineering in 2016 from the U.S. Air Force Test Pilot School at Edwards Air Force Base, California. Lippert also earned a Master of Science in systems engineering in 2019 from the Naval Postgraduate School in Monterey, California. He is currently pursuing a doctoral degree in aerospace engineering at the University of Alabama Graduate School in Tuscaloosa, Alabama. His research focuses on high-speed gas dynamics, including supersonic and hypersonic fluid mechanics.
Awards

Lightning struck a Chinese rocket shortly after liftoff this week, as seen in incredible video and photographs.
A Long March-3B rocket lifted off from China's Xichang Satellite Launch Center on Thursday (July 23) carrying a communications relay satellite destined for geostationary orbit. Some 30 seconds into flight, lightning struck the rocket, leading to awestruck cries from crowds gathered nearby to watch the launch.
Despite the strike, the rocket delivered the satellite to its intended orbit as planned, according to the China Aerospace Science and Technology Corporation (CASC). The satellite will help relay communications to the nation's Tiangong Space Station and other crewed missions.
This isn't the first time lightning has struck a rocket shortly after liftoff. A lightning bolt famously struck the Saturn V rocket carrying NASA's Apollo 12 mission, the second to ever land astronauts on the moon. In fact, the rocket was struck twice.
According to a report NASA issued after the mission, some non-essential instruments and sensors experienced "permanent effects" from the strikes. Nevertheless, the mission put astronauts Charles "Pete" Conrad, Alan Bean and Richard "Dick" Gordon on the moon as planned.
More recently, lightning struck a Russian Soyuz rocket in 2019 shortly after it launched. Like in this most recent example, the vehicle was able to place its Glasnost communications satellite in orbit despite the strike.

But not all rockets struck by lightning fare so well. In 1987, a bolt struck the United Launch Alliance Atlas/Centaur-67 rocket, leading to a malfunction in one of the computers that guided the vehicle and "ultimately causing the breakup of the vehicle," NASA wrote in a report of the incident.
The incident led to NASA developing strict Lightning Launch Commit Criteria (LLCC) to lower the risk of strikes by further defining weather conditions that would delay launches. "Since Atlas/Centaur-67 and the rigorous implementation of the LLCC, no other launch vehicles have intercepted or triggered lightning on launch in the United States," NASA wrote in a technical paper outlining the criteria.
NASA’s Juno mission scientists have reported the first successful temperature measurements below the surface of Jupiter’s moon Io, including indications of significant heating within the moon’s shallow subsurface.
Collected during a pair of close flybys of the Solar System’s most volcanically active world, the Juno mission measurements were described as a complete “surprise” since the instrument was designed for a different purpose.
“[The readings] break new observational ground for both fiery and icy worlds beyond our planet,” the team said.
MWR Instrument Designed to Probe Jupiter’s Atmosphere Provides Double Duty
Due to the extreme gravitational pull of its host planet, Jupiter, Io is repeatedly stretched and pulled as its slightly elliptical orbit carries it around the massive gas giant. This repeated motion generates a tremendous amount of heat, which the scientists note is “many times greater” than the same type of heat generated on Earth.
However, a detailed understanding of this process has remained elusive, as the only data on the moon’s inner heat came from infrared telescope observations. The team notes this data is limited to the temperature of Io’s upper rocky surface layer.
Conversely, Juno is equipped with an instrument called the Microwave Radiometer (MWR). According to the team’s statement announcing the successful subsurface temperature detection, Juno’s Microwave Radiometer was custom designed by Scott Bolton, the mission’s principal investigator at Southwest Research Institute in San Antonio and a co-author of the study detailing the team’s findings, to “peer beneath Jupiter’s top clouds” for a closer look at the gas giant’s complex atmosphere.
“The MWR’s six microwave antennas serve as a single instrument, simultaneously detecting microwaves at a wide range of wavelengths, from about half an inch to 20 inches (1.3 to 51 centimeters),” the team explains.
“Everywhere We Looked, We Found the Temperature Rising”
Bolton said the team’s novel approach allowed the instrument to observe wavelengths from different depths, “providing a new way to characterize the deep atmosphere of giant planets and the subsurface crusts of icy and rocky moons.” This included observations of Jupiter’s other ‘Galilean’ moons, Ganymede and Europa.
“At Ganymede and Europa, we explored tens of miles below the surface, assuming their ice shells were mostly pure water,” the mission scientists explained.
However, Bolton added, using the instrument to successfully probe into Io’s volcanic rock “was an unexpected discovery.”

The feat was accomplished during a pair of flybys on December 30, 2023, and February 3, 2024, where Juno came within roughly 930 miles (1,500 km) of Io’s surface. Shannon Brown, the paper’s lead author at NASA’s Jet Propulsion Laboratory in Southern California, said that during these flybys the MWR instrument measured the moon’s thermal emission “at depths ranging from a few inches down to tens of feet.”
“Everywhere we looked, we found the temperature rising by more than 40 degrees Fahrenheit just several feet into the surface — a gradient far steeper than solar heating alone can explain,” Brown said.

Although more information is likely needed to make a conclusive determination, the team said that the data suggests two possible explanations for the readings. The first option is heat rising steadily through what the team termed a “conductive crust.”
“While this background heat flow — measured at 1 to 3 watts per square meter — is relatively gentle on a local scale (roughly equivalent to a small nightlight glowing under every square yard), across the entire moon it represents a release of energy up to 30 times Earth’s average,” they explained.
Another possibility proposed by the joint research team suggested that the heat signal detected by Juno’s MWR could be coming from cooling lava flows covered by 30 to 35 feet (9 to 11 meters) of solidified crust that cover approximately 10% of Io’s surface “at any given time.”
A Similar Instrument Could be Used to Scan Earth
When discussing the implications of the team’s findings, Bolton said the “surprising” ability to see below Io’s surface “has important implications for studying Earth’s volcanoes.” He also noted that if scientists used a similar instrument to measure areas on Earth near volcanoes, they might see a similar heat signature in the planet’s subsurface temperature gradient, “providing new information on how terrestrial volcanoes work.”
“Io provides a unique window into learning how tidal heating works throughout the cosmos, a fundamental process that provides energy and heat to worlds that are far from their parent star,” Bolton explained. “This process can not only create the most volcanic body in the solar system, in the case of Io, but also fuels the subsurface oceans on the moons of giant planets, such as Europa and Ganymede.”
“Up until this point, we could only observe the heat escaping at the surface or through eruptions,” the mission scientists added. “Now we can characterize how the heat is moving from the interior toward the surface.”

The world's most powerful solid-fuel rocket just aced its third-ever mission.
Gravity-1, a distinctively squat and stubby rocket, launched Tuesday night (July 21) from the deck of a ship stationed off the coast of Shanghai.
Liftoff occurred at 10:54 p.m. EDT (0254 GMT and 10:54 a.m. Beijing time on July 22), according to the state-run Chinese outlet Xinhua, which further reported that all nine satellites reached "their designated orbits." Details about those satellites were not provided.

Gravity-1 is operated by Orienspace, a company based in the eastern Chinese province of Shandong. The rocket stands about 100 feet (30 meters) tall — less than half the height of SpaceX's workhorse Falcon 9 vehicle.
Gravity-1 consists of three core stages and four strap-on boosters, all of which feature solid rocket motors. The launcher can haul up to 14,300 pounds (6,500 kilograms) of payload to low Earth orbit (LEO), making it the most powerful solid rocket in the world. (For comparison: The liquid-fueled Falcon 9 can deliver a maximum of 50,265 pounds, or 22,800 kg, to LEO.)
The Chinese vehicle now has three flights under its belt, all of which launched from ships at sea and achieved full mission success. Gravity-1's first two flights occurred in January 2024 and October 2025.
There won't be such a long gap before Gravity-1 flies again, if all goes to plan. The rocket is expected to launch a batch of Chinese internet satellites in the next few months, according to the state-run outlet CGTN.
And Orienspace's ambitions don't end with Gravity-1. The company is also developing Gravity-2 and Gravity-3, larger, more powerful rockets that will feature liquid-fueled core stages and solid rocket boosters.
Gravity-2 could be ready to fly by the end of the year, CGTN reported. And that vehicle will likely lift off from an ocean-based pad as well.
"Sea launch of solid-propellant rockets paves the way for future launch of liquid rockets at sea," said Gravity-1 chief designer Xu Guoguang, according to CGTN. "We are also considering other methods, such as launching from drilling platforms."
The fight continues against SpaceX's controversial South Texas land swap.
That deal, which the company made with the U.S. Fish and Wildlife Service (USFWS), gives SpaceX 727 acres (294 hectares) of public land that's currently part of the Lower Rio Grande Valley National Wildlife Refuge. In exchange, the company hands over 683 acres (276 hectares) of its territory in the area, not all of it contiguous, to the USFWS.
Last month, a coalition of conservation and tribal groups sued the USFWS over the swap, saying it degrades the refuge and violates multiple laws, including the National Wildlife Refuge System Improvement Act of 1997. And yesterday (July 20), those groups filed an emergency injunction, asking a federal judge to stop the exchange until the courts can rule on the ongoing case.
"Federal officials are racing to fork over America's public lands to one of wealthiest corporations on Earth before the courts can even weigh in," Laiken Jordahl, national public lands advocate at the Center for Biological Diversity, said in a statement yesterday (July 20).
"This refuge is one of the last places left for the public to enjoy nature in the Rio Grande Valley," Jordahl added. "Why should Texans be forced to surrender even more of their public lands to a trillion-dollar corporation? The court has to intervene now, because once these refuge lands are transferred to SpaceX, they’re gone forever."
The land set to be transferred to SpaceX is near Starbase, the manufacturing and launch hub for the company's Starship megarocket. SpaceX sees Starship as transformational; it's the biggest and most powerful launcher ever built, and it's designed to be fully and rapidly reusable.

Starship remains in the development-and-testing phase. It has flown 12 suborbital test flights to date, all of them from Starbase, and is gearing up for Flight 13 this Thursday (July 23).
These launches pose a threat to the wildlife that the 90,000-acre (36,420 hectares) refuge was established to protect, according to the Center for Biological Diversity, a conservation nonprofit based in Tucson, Arizona.
"A 2024 study found that, after one launch, every single monitored shorebird nest near the launch site suffered egg damage or loss," the organization said in yesterday's statement. "Instead of taking any enforcement actions or working with SpaceX to reduce or eliminate its harm to the refuge, the Service [USFWS] is now citing the resulting degradation as justification for handing the public land to SpaceX."
Some of the land being transferred to SpaceX is part of the Palmito Ranch Battlefield National Historic Landmark, where the final battle of the Civil War was fought. This means the swap also violates the National Historic Preservation Act, according to the Center or Biological Diversity.
The Center or Biological Diversity and its partners also take issue with how the land deal was made.
"The proposed land exchange was first made public in March, but records obtained under the Freedom of Information Act show internal agency planning began as early as April 2025," yesterday's statement reads. "In those discussions with the regional director of the Service, the agency developed 'the most expedited schedule possible' for completing a land transfer and recommended hiring additional staff to meet what they described as an 'optimum timeframe.'"
The plaintiffs in the lawsuit against the USFWS are the Center for Biological Diversity, Save RGV, the Carrizo/Comecrudo Nation of Texas, Inc., and the South Texas Environmental Justice Network.
Once again, the "Land Down Under" is on the apparent uptick for falling space debris.
In early July, the Australian Space Agency reported that objects recovered, dubbed "space balls," are likely pressure vessels from a space launch vehicle. Six spherical pieces of space junk were found in the small seaside community of Forrest Beach, near Ingham. Australian Queensland Fire Department crews swung into action to assist partner agencies following the discovery of the potentially hazardous objects. Scientific teams safely secured a number of the items, establishing a 165 feet (50-meter) "exclusion zone" around them to assure public safety. The nature and origin of the debris are still being investigated.
This latest incident is part of an unwanted legacy of being the "fall guy" for space remains, from the U.S. Skylab space station debris that fell into Western Australia in 1979; a chunk of a SpaceX Dragon trunk found in New South Wales in 2022; a pressure vessel that washed up in Perth from an Indian booster in 2023; along with a section of Chinese Jielong-3 rocket in October 2025.
In fact, these incidents are becoming so common that the Australian Space Agency has put together a trio of steps to take if suspected space debris is discovered:
Step 1: Do not handle the debris. Space objects are built from a range of materials that may be hazardous. They should only be handled by appropriately trained and equipped professionals.
Step 2: Contact the local authorities if (a) the situation is potentially urgent (e.g. there is a life-threatening situation) or (b) otherwise contact the 24/7 Police Assistance Line for further advice.
Step 3: Notify the Australian Space Agency, who may support authorities with technical expertise, liaise with foreign counterparts and operators, and advise on the country's treaty obligations. The ASA can advise local authorities on the appropriate response to a confirmed space debris event.
Indeed, if an item is definitely found to be space debris, the Australian Government has worldwide obligations to notify the launching authority of its discovery, and upon request, may be required to return the space junk.

"Even if they heat up, they don't care."
For Marlon Sorge, executive director of the Aerospace Corporation's Center for Orbital and Reentry Debris Studies (CORDS), it's no surprise that the recent so-called space balls endured their plunge from space.
"Very often they will be made of something like titanium which is really good at surviving," Sorge told Space.com. "In spite of them being metal, they tend to decelerate more than, say, a solid hunk of metal. They can 'float down' a little bit more gently than some other things," he said.
Sorge said that this class of space debris decelerates quicker, and also once on the surface the pieces are also more recognizable than broken up chunks of metal. Furthermore, if made of titanium, "even if they heat up, they don't care." In other words, they tend to survive reentry intact.
There's more awareness in the space debris study community that materials like titanium are potentially an issue, said Sorge. If you go to something like Composite Overwrapped Pressure Vessels (COPV), also commonly used in manufactured space hardware, that too is an issue you have to deal with, he said.
Bigger picture
But ultimately, many of these debris concerns could be mitigated with more responsible behaviors from space agencies and launch providers, Sorge said.
"In the bigger picture with [rocket] upper stages," Sorge added, "just don't let them randomly reenter. Bring them down via controlled reentry and then if they are survivable it doesn't matter because you dump them somewhere where there aren't any people."
As for the Australian-found space leftovers, these tanks are clearly coming from non-controlled reentry events, said Sorge, dropping out of the sky and washing up onshore.
Over the years, the Aerospace Corporation has studied recovered pressure vessels like those from the Australian affair. The welcome mat is open for contributions from countries that are on the receiving end of space objects, Sorge advised.
Some information can be gleaned from such appraisals, like what shape the recovered debris is in, what degree of temperatures they were exposed to. Also, such a hands and eyes-on look can point out what they didn't experience, which is also useful data, Sorge said.
If observers could track and observe incoming debris on its way down, it could be extremely helpful in identifying points of origin. That's currently a challenge, Sorge said. "If we get an impact location and a time of reentry that really helps us figure out what's going on," he said.
On the whole, there's a lot more attention being paid to the implications stemming from reentering, human-made, space leftovers.
"The real challenge is that this is still an area that we don't completely understand. We get surprises now and again," Sorge concluded, "because we know only so much. There's certainly a lot more awareness now than earlier years to be proactive in thinking about this."

Atmospheric drag wins
"It may seem surprising that pieces of the same rocket can show up in Australia, Canada or on a farm in Africa, but that's actually what we'd expect," said Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi School of Law.
"Objects in low Earth orbit pass over much of the planet as the Earth rotates underneath them. If a reentry isn't controlled, the exact point where it finally comes down can shift by thousands of kilometers depending on when atmospheric drag finally wins," Hanlon told Space.com.
Since most of the Earth is ocean, that's where most debris ends up, Hanlon said. "Every now and then, though, a tough piece survives and lands somewhere people can find it — or lands in the ocean and gets swept swiftly to shore."
Country of origin?
Hanlon said that the pressure vessels like those found in Australia are a good example.
"They're built to withstand enormous pressures, so they are also among the pieces most likely to survive reentry. That's why they seem to turn up so often," said Hanlon.
Why are recovered space debris so hard to identify, their country-of-origin?
"I'm not sure stamping everything with a country-of-origin is the answer," said Hanlon. "Many of these objects can already be identified by their design, serial numbers or by matching them to launch and registration records. And there's no guarantee a label would even survive reentry."
For Hanlon, the bigger issue is traceability. "Can authorities quickly figure out what the object is, whether it poses any danger and which state should be contacted? Better information-sharing and better tracking would be far more useful than a 'Made in' stamp," Hanlon said.
"One thing I'd also point out is that we're seeing more of these simply because we're launching a lot more things into space. That's actually a sign of how active the space sector has become, not necessarily that it's becoming less safe," said Hanlon.
Even if reentries go exactly as planned 99.9 percent of the time, more launches mean more reentries, which means more chances that a particularly durable piece survives and lands somewhere unexpected.
All-in-all, the Australian incident of space balls is another sobering reminder that space activities don't end when a mission does, Hanlon concluded. "End-of-life disposal is now just as much a part of responsible space operations as launch."
This recent debris incident has a bit of a cosmic coincidence to it, too, Hanon added. "It's funny that we're having this conversation just as 'Spaceballs: The New One' is gearing up."
