Europa, one of Jupiter’s largest moons, has fascinated scientists for decades because it may hide a vast ocean of liquid water beneath its thick icy surface. Since liquid water is one of the key ingredients needed for life, Europa is considered one of the most promising places in our solar system to search for signs […]
Indian space officials celebrated the debut flight of Skyroot Aerospace's Vikram-1 rocket, India's first fully commercial satellite launcher, as a "grand success" Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal.
The Vikram-1 lifted off from India's primary spaceport on Sriharikota Island at 1:35 am EDT (06:35 UTC) Saturday, around midday at the launch base along India's southeast coast. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1's solid-fueled first stage booster to propel the rocket off the launch pad.
Vikram-1 is modest in size compared to India's larger workhorse rockets. Skyroot's rocket stands about 72 feet (22 meters) tall, with the capability to place payloads of up to 770 pounds (350 kilograms) into low-Earth orbit. This makes Vikram-1 somewhat larger than the Electron launch vehicle developed by Rocket Lab, the world's most successful dedicated small satellite launcher.

An innovative new drone dubbed the “Phantom Twist” can seemingly disappear from view, in a major new robotics advancement offering a close-to-invisible aerial platform.
Its name describes the drone’s rapid spinning motion, which rotates 25 times per second—too fast for the human eye to resolve—thereby acting as a sort of cloak shielding it from visible detection.
The Northwestern University engineering team behind the Phantom Twist revealed their drone during a recent talk at the Sydney, Australia, Robotics: Science and Systems 2026 conference on July 16.
Stealth Drones
“Most efforts to hide drones focus on making them look like their surroundings,” said Northwestern’s Michael Rubenstein, who led the work. “Instead, we asked whether we could design the drone itself around the way humans perceive motion. This idea of low visibility through persistent motion is something few people have explored.”

Hiding drones is not a new idea. Other engineers have attempted a variety of techniques, including camouflage, transparent materials, and light-bending to obscure the presence of drones and robots. However, all of those focused on the material the drone’s exterior was constructed from, allowing it to blend into the background. The Northwestern team’s innovation was in how the object moves.
To our eyes, fan blades disappear because they are moving so fast that our eyes cannot track them. The “motion blur” created at these speeds allows the Phantom Twist to almost disappear, leaving only a faint apparition perceptible to the eye.
Nature Drones
While several military applications are immediately obvious, the team instead says their work could be useful in developing noninvasive wildlife and environmental monitoring. Loud drones can scare wildlife, disrupting them as they scatter, but by blending in, the Phantom Twist could capture a much more accurate picture of natural behaviors.
Their perception-based design eschews the traditional quadcopter design for a single propeller, with a body that spins in the opposite direction, creating the optical illusion that the drone essentially disappears.

“For a typical quadrotor drone, the propellers are spinning, but the robot is stationary,” Rubenstein said. “So, you still see its body. For our drone, the whole thing is rotating, so there are no stationary parts.”
Creating the Phantom Twist
Using AI and optimization algorithms, the Northwestern team began by generating 20,000 different arrangements of a drone’s propeller, motor, circuit board, and other necessary components. Eventually, the algorithm landed on the most promising configurations, after which the researchers simulated and superimposed them onto real-world backgrounds.
Another computer model mimicked human perception, allowing the engineers to assign a perception score for how visible each design would be to human eyes. An algorithm then optimized those designs by moving components to minimize the visibility score even further.
“The design process was fully automated,” Rubenstein said. “Then, when we were confident that a drone met all our criteria, we built it.”
A Revised Drone
The key feature of this design is that the individual components are at such varying heights and angles that they do not overlap as it spins, maximizing the motion-blur effect and creating the appearance of a faint cloud rather than a solid object.
“The human eye takes time to accumulate signals, roughly analogous to the exposure time of a camera,” said Alexander, an expert in computer vision. “When an object spins quickly, we perceive it as blurring out and losing distinct features. Because this new drone is almost entirely transparent, its few opaque components are visually averaged with the background for an overall appearance of a slight haze.”
Currently impeding the drone from being even more imperceptible to the eye are the wires and support rods that remain visible, as well as the engine noise it produces, which is readily discernible. Going forward, the team plans to continue improving Phantom Twist in future iterations to incorporate more transparent materials and reduce the noise it produces.

Welcome to Edition 9.01 of the Rocket Report! Back in January, I wrote about the 20 launches and landings we were most excited about in 2026. The list included things that were, at the time, officially scheduled to occur this year. I also gave my own view of the probability of each of these events actually happening before December 31. Halfway through the year, we can only count one of the events as completed, and that was NASA's Artemis II mission in April. Many are now scheduled for next year, proving again that delays are a constant in the space industry. A couple of them—such as the launch of NASA's Roman Space Telescope—do appear to be on track to happen soon.

Swift Boost Mission reaches orbit. A pioneering commercial mission to reboost the orbit of NASA's Swift astronomy satellite launched early Friday after attempts earlier in the week were thwarted by bad weather and a technical issue. The Link servicing satellite developed by Katalyst Space Technologies soared to orbit on the tip of a Northrop Grumman Pegasus XL rocket that dropped from the belly of a modified L-1011 jetliner over the remote Pacific Ocean. Mission managers called off two launch attempts Tuesday and Wednesday due to poor weather around the L-1011's staging base on Kwajalein Atoll in the Marshall Islands. On Thursday, "a launch vehicle issue temporarily prevented teams from deploying the rocket" after takeoff of the L-1011.
An innovative new approach to building safer, more efficient small unmanned aerial vehicles is taking a cue from nature.
Anticipating worsening turbulence due to environmental concerns in the coming years, engineers studying the unmatched hovering ability of kestrels hope to reverse engineer the secrets of their exceptional flight capabilities to help assemble better future drones.
Smaller drones, known as sUAVs, have a range of different applications that include delivery services, photography, and more. However, wind conditions can often cause turbulence that either grounds them temporarily or, when caught off guard, can lead to their destruction.
Now, a team of researchers has published their findings in the Journal of the Royal Society Interface, which details an ongoing collaboration between RMIT University and the University of Bristol that seeks to overcome such issues by building drones that operate more like some of nature’s best flyers.
Specifically, the nankeen kestrel is an avian species whose amazing prowess while flying during adverse conditions still confounds researchers. To unravel the secrets of their flight, the researchers used motion capture technologies made possible in RMIT’s special Industrial Wind Tunnel facility, one of the largest such facilities anywhere on the Australian continent.
“Birds don’t rely on a single response to wind gusts,” according to RMIT researcher Matt Penn. “They constantly adjust their wings and tails to stay balanced, while the natural flexibility of their feathers and joints helps absorb sudden changes in airflow.”
“They can also sense disruptions very quickly, which allows them to respond almost instantly and maintain control,” added Penn, one of the team members who co-led the studies into how birds can cope with turbulence.
According to Penn and his colleagues, these birds possess a range of unique strategies that help them overcome the dangers of turbulence, which help them navigate under conditions that would cause most sUAVs to come tumbling from the sky.
To attempt to understand what makes kestrels such adept fliers, the team created a robotic replica to mimic some of their key flight movements and characteristics, which allowed the team to unravel some of the secrets to how these incredible birds perform.
“By creating a robot replica, we were able to measure how specific movements were contributing to steadiness in flight,” said Dr Mario Martinez Groves-Raines, a researcher now with the Royal Veterinary College in London, adding that precision measurements of kestrel flight that normally could not be achieved in nature were possible using the team’s robotic version.
“We uncovered several unique techniques behind the kestrel’s impressive stability,” Groves-Raines said. “Many of these techniques have the potential to improve [the] manoeuvrability of small aircraft, which encounter similar challenges to kestrels.”
“This research shows what’s possible when engineers look to nature for solutions,” added RMIT senior researcher Associate Professor Abdulghani Mohamed.
“Our findings open new pathways for designing aircraft that can better handle turbulence.”
Going forward, the researchers say they hope to apply their findings toward the construction of novel sUAVs, which can help future drones operate safely and more efficiently, much like their agile avian forebears.
Ultimately, similar engineering in the coming years may have applications that extend well beyond just drone flight, and could also help to ensure safe operations for much larger aircraft.

Electric Vertical Take-Off and Landing (eVTOL) pioneer Archer Aviation has confirmed that it is on track to perform Team USA transport duty during the 2028 Summer Olympics in Los Angeles, California, aboard its Midnight aircraft.
In an email to The Debrief, a company spokesperson said Archer was selected as the Official Air Taxi Provider of the LA28 Olympic Games and Team USA, marking a historic first in the quest for commercial eVTOL operations before the end of the decade.
“Through this exclusive partnership, the two will look to integrate Archer’s Midnight eVTOL aircraft across theLA28 Games in a variety of ways, such as transporting VIPs, fans, and stakeholders, while electrifying vertiport take-off-and-landing hubs for key venues and providing support for emergency services and security,” a company spokesperson explained.
Archer CEO Announces ‘Progress’ Including Upcoming Midnight eVTOL Test Flight in 8 US Cities
Archer Aviation founder and CEO Adam Goldstein recently shared more specific updates about the company’s road to the Olympics and eventually government approval, noting that “we made tremendous progress towards beginning operations in the US later this year, with record FAA certification progress and our most expansive flight testing to date.”
Goldstein also highlighted the company’s recent winning applications to begin pre-certification test flights of Midnight in 8 US states later this year, including New York, Florida, and Texas. According to the CEO, those test flights are part of the eVTOL Integration Pilot Program (eIPP), “which was unlocked through the White House’s Executive Order in June last year.”
“Archer expects Midnight operations in American cities to begin this year as part of the White House’s eIPP and in preparation to serve as the Official Air Taxi Provider of the LA28 Olympic Games, in coordination with the DOT and FAA,” the CEO explained, adding that the two benchmarks “pave the way for Archer to showcase its air taxi technology in parallel with its continued work toward FAA Type Certification for Midnight.”
Six Independently Operating Engines Produce Over 1,500 Horsepower, Last 10,000 Flight Cycles
When asked about the technical aspects that have put Midnight on course to become the first commercial eVTOL air taxi provider in the U.S., the company spokesperson first noted that their aircraft are “designed and manufactured” domestically, which can shorten development timelines and improve quality control. This includes focusing the team’s research and development on what the company termed “differentiating technologies,” including the pioneering aircraft’s unique powertrain.
“Our world-class in-house team, coming with experience from Apple, Tesla, SpaceX and beyond, contribute to our efficient and certifiable electric propulsion design,” the company told The Debrief.

Some of the differentiating technologies the team said set it apart from the competition include rapid charging, long-lasting battery packs “and the capability of >1500 horsepower.” They also note that Midnight’s high-performance battery cells, patented high-voltage architecture, and gearbox are designed to operate reliably for roughly 10,000 “flight cycles” before the vehicle’s battery pack needs replacement.
“We are optimized for electric flight,” the company told The Debrief.
Due to the potential risks in premiering a new vehicle platform, with Archer Aviation telling The Debrief that “eVTOL aircraft are the first new category of aviation in more than 60 years,” the company said Midnight is built as a ‘fly-by-wire’ system, reducing the number of mechanical components that can fail. The company also said that each of Midnight’s engines operates independently “allowing for high levels of redundancy and safety.”
Although the current version of the Midnight eVTOL aircraft is flown by a human pilot, the company told The Debrief that it is “continuing to build the technology stack” required for its longer-term goal of a fully autonomous eVTOL aircraft.
Company Anticipating Final FAA Approval “in the Near Future”
With the 2028 Summer Olympics just two years away, the company said it has transitioned out of a successful Phase 3 of the FAA’s 4-phase Type Certification process, an industry first, and has “already been advancing its work in Phase 4 for some time now.”
“This is where Midnight’s compliance with FAA airworthiness requirements will be demonstrated through formal testing and analysis,” the company told The Debrief.
In his address to shareholders, Goldstein said the company’s flight test program “continued to expand this quarter.” The CEO said this expansion includes piloted VTOL and CTOL flights across its expanded fleet of test aircraft “occurring nearly every day, often multiple times a day.”
Archer Aviation has recently taken over operations at Hawthorne Airport with goals of creating the airport of the future.
To expedite the testing phases leading up to the 2028 Olympics, the company recently took over operations of Hawthorne Airport in Los Angeles County. Goldstein said the move will help Archer develop the local airstrip “into the airport of the future.”
“Located near LAX and several major LA sports and entertainment venues, Hawthorne Airport is expected to anchor Archer’s planned LA air taxi operations while also serving as an innovation hub for next-generation aviation technologies,” the CEO explained.
When asked how soon the company expects to fulfill the FAA’s Phase 4 requirements and gain full certification, the spokesperson told The Debrief that Archer is in the final stages of the process, “and is anticipating approval in the near future.” However, the company also added that their focus is on building a safe, high-performance aircraft, and that once they can demonstrate the safety and versatility of Midnight, “it is the FAA’s job to certify it.”

Welcome to Edition 8.46 of the Rocket Report! We don't mention Starship in the body of this week's report, so I'll give a brief update here. The next test flight of SpaceX's mega-rocket—Flight 13—could happen as soon as next month, according to Gwynne Shotwell, the company's president and chief operating officer, in a recent interview with CNBC. There's still a fair bit of work to do before Flight 13, so don't count on a launch next month just yet. What we do know, based on Shotwell's comments to CNBC, is the next Starship test flight will look a lot like the previous one last month, with a suborbital flight path and a splashdown of the ship in the Indian Ocean. SpaceX is holding off on an orbital flight until at least the following launch, Flight 14, after the ship was unable to complete a critical engine restart in space on the last flight.

Isar test flight scrubbed again. Isar Aerospace still commands top position among a new generation of European rocket startups, but the company’s efforts to launch a critical test flight of its Spectrum rocket continue to encounter roadblocks, Ars reports. The latest delay came Monday, when Isar scrubbed a launch attempt after "detecting off nominal behavior in the vehicle’s fluid systems," according to a social media post. "The teams are analyzing the new data to isolate the root cause." Isar is flush with cash, having raised nearly $1 billion to date, but is still lacking in the critical currency of flight experience. The Spectrum rocket has flown just once to date, on a failed launch last year that lasted less than 30 seconds.

A robotic spacecraft built by a Flagstaff, Arizona, startup is preparing to chase down one of NASA’s space telescopes and boost it into a higher orbit. Katalyst Space Technologies’ craft, called LINK, is set to launch later this month aboard an air-launched Northrop Grumman Pegasus XL rocket from Kwajalein Atoll in the Marshall Islands, then rendezvous with NASA’s Neil Gehrels Swift Observatory and raise its altitude.
The target is a telescope that cannot save itself. After 21 years in orbit, Swift is sinking. The spacecraft carries no thrusters of its own, and its low Earth orbit has been decaying for years as it brushes against the top of the atmosphere. A recent stretch of heightened solar activity made the problem worse, puffing the atmosphere outward, thickening the drag, and pulling Swift down faster than NASA had planned for.
A telescope built to chase explosions
Swift launched in 2004 to study gamma-ray bursts, the most powerful explosions in the universe. NASA describes it as a kind of cosmic dispatcher: when a sudden, violent event flares somewhere in the sky, Swift pins down where it happened and alerts other observatories to swing around and look. Over two decades it has fed discoveries about exploding stars, flares from distant galaxies, comets, asteroids, and even high-energy lightning on Earth.
Goddard Space Flight Center in Greenbelt, Maryland, manages the mission, with partners that include Penn State, Los Alamos National Laboratory, the UK Space Agency, the University of Leicester, and the Italian Space Agency. Losing the telescope to an uncontrolled reentry would end all of that.
A race against the clock
Rather than let Swift fall, NASA decided to try something it had never done with a science satellite. In September 2025 the agency awarded Katalyst a $30 million contract, routed through its Small Business Innovation Research program, to mount a robotic boost on a compressed schedule. NASA framed the speed itself as the point, calling the effort a way to prove it can go from concept to implementation in under a year.
“This is a forward-leaning, risk-tolerant approach for NASA,” said Shawn Domagal-Goldman, the acting director of NASA’s Astrophysics Division at the time of the award, who noted that boosting Swift is both cheaper than building a replacement and a way to extend satellite servicing to “a new and broader class of spacecraft.” The clock is real: without a boost, NASA expects Swift to reenter the atmosphere in the fall of 2026, and for the rescue to have its best chance the telescope needs to stay above roughly 185 miles, about 300 kilometers. To buy time, controllers suspended Swift’s science observations and reoriented the spacecraft to cut its drag, a change the mission had never made before.
Why an air-launched rocket
The choice of a Pegasus XL is itself a consequence of the rush. Swift sits in an unusually low-inclination orbit of 20.6 degrees, which is hard to reach from U.S. launch pads, where most small rockets are confined to steeper angles. Pegasus solves that by skipping the pad entirely: Northrop Grumman’s modified L-1011 aircraft, named Stargazer, carries the rocket aloft and releases it in midair, letting it start its climb from tens of thousands of feet and from a location chosen to match Swift’s path.
A first, if it works
NASA has been careful about what it is claiming. By the agency’s own description, a successful boost would be the first time a commercial robotic spacecraft captures a government satellite that is uncrewed, or not originally designed to be serviced in space. That qualifier matters. Robotic servicing has been demonstrated before on craft fitted with docking targets or otherwise built to be approached; Swift was not. LINK, an 880-pound spacecraft that grips its target with three robotic arms, will have to dock with an observatory that was never built to cooperate with a visiting robot, over a maneuver NASA expects to unfold across several months.
It is also, for now, an attempt rather than a sure thing, and the schedule remains soft. NASA has described the launch as targeted for later in June while cautioning that shifting solar activity could still move the timing. Whether the boost works or not, it is a test of a capability NASA says it will need as satellites pile up in orbit and more of them, someday, may be worth saving rather than discarding.
