Russia launched a cargo mission toward the International Space Station today (Sept. 16), delivering the freighter spacecraft to orbit for a three-day rendezvous journey.

The robotic Progress 96 spacecraft lifted off atop a Soyuz rocket from the Russian-run Baikonur Cosmodrome in Kazakhstan today at 9:33 a.m. EDT (1333 GMT).

From engine ignition through solar array deployment on the spacecraft, the Progress 96 launch was completely nominal. It was "a flawless launch," said NASA's Rob Navias during the mission's livestream this morning, with "an excellent climb to orbit by the Soyuz booster."

Progress 96 is loaded with about 3 tons of food, propellant and other supplies for the astronauts aboard the International Space Station (ISS). The freighter will deliver this cargo three days after launch, if all goes according to plan. You'll be able to watch rendezvous and docking activities when the time comes.

The freighter will remain docked to the orbiting lab for about five months. It will then be loaded up with trash and sent down to a fiery death in Earth's atmosphere over the Pacific Ocean.

The Progress 94 spacecraft met this fate on Sept. 7, departing from ISS' Poisk module to make room for Progress 96.

Progress is one of four spacecraft that fly operational cargo missions to the ISS these days, along with Japan's HTV-X, SpaceX's Dragon capsule and Northrop Grumman's Cygnus. All but Dragon are expendable, burning up in our air when their time in orbit is up.

There are currently seven people living aboard the ISS — NASA astronauts Jack Hathaway, Jessica Meir and Anil Menon; the European Space Agency's Sophie Adenot, who last month became the first French woman ever to perform a spacewalk; and Pyotr Dubrov, Andrey Fedyaev and Anna Kikina of the Russian space agency Roscosmos.

We now have a launch date for Starship's most ambitious mission to date.

SpaceX announced today (Sept. 15) that it's targeting Sept. 22 for the first orbital flight of Starship, the fully reusable megarocket that the company is developing to help humanity settle the moon, Mars and more.

Liftoff, from SpaceX's Starbase site in South Texas, will occur during a 75-minute window that opens at 8:15 a.m. EDT (1215 GMT and 7:15 a.m. local Texas time). You can watch it live here at Space.com when the time comes.

The upcoming flight will be the 14th overall for Starship, which debuted in April 2023 and has flown twice so far in 2026. But the 408-foot-tall (124-meter-tall) vehicle's first 13 jaunts were all suborbital, so Flight 14 will be a landmark.

"By going to orbit, the next phase of developing Starship to be fully and rapidly reusable can begin," SpaceX wrote in a Flight 14 mission description.

"This will also mark the first time we plan to deploy Starlink V3 satellites into the constellation, delivering a payload that will dramatically expand connectivity speeds and reliability around the world," the company added.

Starlink, SpaceX's network of broadband satellites in low Earth orbit, currently consists of more than 11,000 active spacecraft. None of those are the larger, more capable V3 version, which are designed to launch on Starship.

Flight 14 will carry up 26 of these next-gen craft — the first of many, if all goes to plan. SpaceX founder and CEO Elon Musk has said the company wants the Starlink megaconstellation to eventually consist of 100,000 V3 satellites.

Three of the Starlink craft launching on Flight 14 have been outfitted with cameras and will photograph the heat shield on Starship's upper stage, known as Ship, after deployment. SpaceX will use this imagery to study and potentially improve the heat shield, which protects Ship during its return trip through Earth's atmosphere.

If all goes according to plan on Sept. 22, the 171-foot-tall (52-m-tall) Ship will complete six orbits of Earth at an altitude of about 171 miles (275 kilometers). The vehicle will then maneuver its way to a splashdown in the Pacific Ocean west of Chile about 10 hours after launch, SpaceX wrote in the mission description.

That's a very different plan than previous Starship flights. On those suborbital missions, Ship stayed aloft for just 65 minutes or so, did not complete an orbit of Earth and came down in the Indian Ocean, off the coast of Western Australia.

But Flight 14 will be more of the same for Starship's first-stage booster, known as Super Heavy. If all goes to plan, the giant rocket will splash down in the Gulf of Mexico about seven minutes after liftoff, as it has done on a number of previous flights.

So there will be no catch — of either Ship or Super Heavy — by the "chopstick" arms of Starbase's launch tower on Flight 14. SpaceX has pulled off tower catches of Super Heavy on three occasions to date but has never done so with Ship. This recovery method will eventually be the norm on Starship flights, leading to faster and more efficient reuse of the vehicle, Musk has said.

So, while Flight 14 aims to check a very big box — reaching orbit — other milestones will be reserved for future flights. A Ship tower catch will be among the most anticipated, along with refueling the vehicle in orbit, something that will be required for missions to the moon, Mars and beyond.

SpaceX launched its second classified mission for the U.S. Space Force in less than a week tonight (Sept. 16).

A Falcon 9 rocket lifted off from California's Vandenberg Space Force Base today at 9:07 p.m. EDT (6:07 p.m. local California time; 0107 GMT on Sept. 17).

We don't know much about tonight's mission, which was called USSF-259. SpaceX's webcast didn't shed any light of note; it ended shortly after the Falcon 9's first stage returned to Earth for a landing in the Pacific Ocean atop a drone ship about 8.5 minutes after launch.

That touchdown was the 13th for this particular booster, which is designated 1097. One of the booster's previous landings was a big milestone for SpaceX. This past April, B1097 pulled off SpaceX's 600th touchdown of an orbital-class rocket, during a launch that sent 25 of the company's Starlink internet satellites to low Earth orbit.

Tonight's mission was the second that SpaceX has flown for the U.S. Space Force in a six-day span: A Falcon 9 launched the similarly classified USSF-153 from Vandenberg on Sept. 10.

Tonight's launch was SpaceX's 110th of 2026. The vast majority of the company's flights so far this year — 106 of them, in fact — have been performed by the workhorse Falcon 9.

The powerful Falcon Heavy has launched twice in 2026, as has SpaceX's next-gen megarocket, Starship. Both Starship liftoffs this year have been suborbital test flights. The next Starship launch, which is expected to occur in the next two weeks, will apparently take the vehicle orbital for the first time.

Editor's note: This story was updated at 11:50 p.m. ET on Sept. 15 with the new launch date of Sept. 16. It was updated agai at 9:28 p.m. ET on Sept. 16 with news of successful launch and rocket landing.

Two European Earth-observing spacecraft lifted off from South America tonight (Sept. 14).

A Vega C rocket carrying the FLEX and Copernicus-3C satellites launched from Europe's Spaceport in Kourou, French Guiana at 9:21 p.m. EDT (10:21 p.m. local time in Kourou and 0121 GMT on Sept. 15).

Both FLEX and Sentinel-3C were deployed as planned. They were released at an altitude of about 509 miles (820 kilometers), and both were flying freely by 116 minutes after launch.

The 875-pound (397-kilogram) FLEX will detect and monitor vegetation fluorescence, which explains its name (a shortening of "Fluorescence Explorer"). By doing so, it will map plant photosynthetic activity — something no satellite can do at the moment, according to ESA.

FLEX's data will be important not only "for a better understanding of the global carbon cycle, but also for agricultural management and food security," ESA wrote in a FLEX mission desription. "This is of particular relevance due to demand the growing world population is placing on the production of food."

Sentinel-3C is part of the European Union's Copernicus Earth-observation program. The 2,520-pound (1,1143-kg) satellite will continue the Sentinel-3 line, which is aging but still going strong in low Earth orbit; Sentinel-3A and Sentinel-3B, which launched in 2016 and 2018, respectively, remain active.

"Like its two older siblings in orbit, Sentinel-3C carries a suite of cutting-edge instruments that measure systematically Earth’s oceans, land, ice and atmosphere to monitor and understand large-scale global dynamics," ESA wrote in a Sentinel-3C description. "It provides essential information in near-real time for ocean and weather forecasting."

The 115-foot-tall (35-meter-tall) Vega C debuted in July 2022 and had seven flights under its belt before today, six of them successful.

The rocket was developed by the European Space Agency and originally operated by the France-based company Arianespace. The Italian outfit Avio now runs the vehicle's liftoffs, however; today's launch was the second Avio has managed.

SpaceX lofted three telecom satellites to orbit today (Sept. 13) on a milestone mission for the company.

A Falcon 9 rocket lifted off from Florida's Cape Canaveral Space Force Station today at 2:49 p.m. EDT (1849 GMT), carrying the final three satellites for Luxembourg-based SES' O3b mPOWER constellation.

It was the 700th mission to date for SpaceX's Falcon rocket family, according to the company. That family first spread its wings in March 2006 when the Falcon 1 debuted. The Falcon 1 flew a total of five times, twice successfully, before giving way to the workhorse Falcon 9 in 2010. The Falcon 9 has conducted the vast majority of the family's flights; the only other member, the still-active Falcon Heavy, has launched 13 times to date.

The Falcon 9's first stage came back to Earth a little less than nine minutes after launch today, landing in the Atlantic Ocean on the SpaceX drone ship "A Shortfall of Gravitas." It was the 29th flight for this particular booster, which is designated B1080.

The rocket's upper stage, meanwhile, continued hauling the O3b mPOWER trio to medium Earth orbit (MEO). The satellites were deployed as scheduled, being released at an altitude of 5,000 miles (8,000 kilometers) over a 14-minute span starting roughly 33.5 minutes after launch.

SES already operates 10 O3b mPOWER satellites in MEO. The spacecraft that went up today will complete the constellation, which is "purpose-built to deliver predictable low latency, exceptional throughput and unprecedented flexibility for industries where uptime isn’t optional," according to the company.

"It transforms how networks operate by pairing advanced software defined satellites with an intelligent ground and software ecosystem — ensuring guaranteed performance, even as global bandwidth demands surge," the company wrote.

The O3b mPOWER satellites, which are built by Boeing, weigh about 3,750 pounds (1,700 kilograms) apiece. SpaceX has launched all of them, on six Falcon 9 launches beginning in December 2022.

Today's launch was SpaceX's 107th orbital mission of the year. The Falcon 9 has performed 105 of those flights, with the Falcon Heavy conducting the other two.

SpaceX has also launched two suborbital test flights of its Starship megarocket in 2026 and is gearing up for the third, which apparently will take the giant vehicle orbital for the first time.

Rocket Lab still holds out hope that it can build NASA's next Mars orbiter.

The agency picked Blue Origin for that job earlier this month, awarding Jeff Bezos' spaceflight company $700 million to develop, launch and operate the Mars Telecommunications Network (MTN).

Today (Sept. 11), however, Rocket Lab announced that it has challenged that decision, filing a formal protest with the Government Accountability Office (GAO).

"NASA's award decision appears to be inconsistent with the eligibility criteria mandated by Congress. In addition, the agency’s punitive review of Rocket Lab's technical volume was inconsistent, making incorrect assertions and conclusions," Rocket Lab said today in an X post that laid out its argument.

"Procurement standards exist to ensure fair competition and protect public investment," the California-based company added. "We are pursuing this review to ensure those standards are upheld for critical infrastructure that will underpin American exploration at Mars for decades to come."

As its name suggests, the MTN orbiter will serve as a communications link between mission controllers here on Earth and other NASA spacecraft studying the Red Planet. Just two agency orbiters fulfill that relay role these days, and both are quite old: Mars Odyssey launched in 2001, and the Mars Reconnaissance Orbiter lifted off in 2005.

NASA had been eyeing a new Mars telecom orbiter for years and finally got Congressional funding for it in July 2025 — $700 million, to be precise. The agency issued a request for proposals this past May, drawing considerable interest from the private sector.

Blue Origin and Rocket Lab were widely considered the front-runners, and NASA ended up going with Blue. The award calls for the company to deliver MTN (which, despite the "network" in its name, is a single spacecraft) to NASA no later than Dec. 31, 2028. It's expected to be up and running at the Red Planet by 2030.

Blue Origin has been in Rocket Lab's shoes before, and has behaved similarly. Bezos' company filed a protest with the GAO in 2021 after NASA picked SpaceX to provide the first crewed moon lander for the agency's Artemis program.

The GAO denied the protest in July of that year. Blue Origin then sued NASA but lost in court in November 2021. The story has a happy ending for the company, however: NASA decided to select a second Artemis lander as well, and Blue Origin won that contract in 2023. We'll see how this story plays out for Rocket Lab...

Rocket Lab just launched a mystery mission to orbit.

An Electron rocket lifted off from Rocket Lab's New Zealand site on Thursday (Sept. 10) at 11:28 p.m. EDT (0328 GMT and 3:28 p.m. local New Zealand time on Sept. 11).

The launched kicked off a mission the company called "Happily Ever Faster," which we know little about.

Rocket Lab did not livestream the mission or reveal who booked it, saying only that it aimed to loft "a single commercial satellite to a 500 km low Earth orbit." That did indeed happen successfully, the company announced via X about 80 minutes after launch.

Speculation has worked to fill the information vacuum, as it generally does. For example, some outside observers think "Happily Ever Faster" carried up a "Gen-3" satellite for the geospatial intelligence company BlackSky.

These spacecraft are powerful Earth observers, capable of resolving features as small as 14 inches (35 centimeters) on our planet's surface. Rocket Lab has launched BlackSky Gen-3 satellites before, so this is a pretty good bet — especially since, in that post-launch X post, the company revealed that the deployed payload was an Earth-observing craft.

"Happily Ever Faster" was Rocket Lab's 16th launch of 2026, and the 13th involving the 59-foot-tall (18 meters) Electron, which gives small satellites dedicated rides to space.

The company has also launched three missions this year with HASTE, a suborbital version of Electron that tests customer equipment in a hypersonic flight environment. All 16 launches in 2026 have been successful.

A pair of private spacecraft just showed off some impressive maneuverability high above Earth.

The two probes — Mira satellites operated by the California startup Impulse Space — zoomed within 650 feet (200 meters) of each other in low Earth orbit (LEO) recently. The rendezvous demonstrated skills that could be useful to a variety of customers down the road, according to the company.

"These types of dynamic, agile maneuvers are how we unlock full access to space after launch and create new mission possibilities," Tom Mueller, CEO and founder of Impulse Space (and, prior to that, the first person Elon Musk ever hired at SpaceX), said in a statement on Tuesday (Sept. 8). "Our teams that design, build and operate Mira are leading the way toward a true space age, and customers across all sectors will be the beneficiaries."

Mira is an orbital transfer vehicle — a spacecraft designed to deliver customer payloads to precise locations in Earth orbit or beyond. The dishwasher-sized Mira can carry up to 660 pounds (300 kilograms) of gear and is highly maneuverable, as the recent rendezvous showed.

The operation involved Mira satellites that launched in January 2025 and November 2025, on missions that Impulse calls LEO Express 2 (LEO-2) and LEO Express 3 (LEO-3), respectively.

The action began this past February, when the LEO-2 Mira conducted a lengthy engine burn to close in on its counterpart. LEO-2 performed additional, smaller burns throughout the spring and summer, coming into orbital alignment with LEO-3.

"Then in July, LEO-2 executed a series of close approaches to LEO-3, starting at about 820 meters [2,690 feet] apart and subsequently moving closer to LEO-3," Impulse Space wrote in the Tuesday update. "Ultimately, for the closest approach, LEO-2 maneuvered to within about 200 meters of LEO-3."

Both Miras chronicled the rendezvous, snapping photos of each other with onboard camera gear. Two other companies, Starfish Space and HEO, worked with Impulse Space to pull off this orbital photo shoot.

Impulse has worked with Starfish before. The duo collaborated late last year on a rendezvous between LEO-2 and the first space-flown Mira, which launched on the Leo Express 1 mission in November 2023.

On that operation, called Remora, LEO 2 used Starfish Space navigation software to get within 4,100 feet (1,250 m) of LEO 1.

"We're showcasing some of the advanced capabilities that set Mira apart from other vehicles," Drew Damon, vice president of spacecraft programs at Impulse, said in Tuesday's statement. "Twice now, we've demonstrated that Mira has the agility and propulsion to support a new class of dynamic operations on orbit, and our team is excited to continue tackling the mission sets Mira is uniquely qualified to handle."

Impulse is not alone in developing and demonstrating orbital maneuverability. Such skills are a key priority of national governments, which want to service and upgrade their own satellites — and keep tabs on the activities of adversary craft. For example, earlier this year, two Russian spacecraft got within a mere 10 feet (3 m) of each other high above Earth.

Frank Culbertson had a birds-eye view of one of the most memorable and tragic events in American history.

The NASA astronaut was the only American off of Earth on Sept. 11, 2001. He was circling the planet aboard the International Space Station (ISS) when terrorists flew commercial jets into the twin towers of the World Trade Center in New York City, killing more than 2,700 people.

The ISS passed over New York shortly after the attacks took place, so Culbertson saw the devastation from an eerie remove. He shared his thoughts with Mission Control at NASA's Johnson Space Center in real time, chronicling the tragedy like no one else could.

"We could see New York City and the smoke from the fires," Culbertson said. "Our prayers and thoughts go out to all the people there and everywhere else here — I'm looking up and down the East Coast to see if I can see anything else — and to the people in Washington."

Terrorists hijacked four commercial planes on 9/11, flying two of them into the World Trade Center and one into the Pentagon in Washington, D.C. Passengers on the fourth plane overpowered the hijackers, forcing it to crash in a field in Pennsylvania rather than hit the terrorists' intended target, which was likely the U.S. Capitol building or the White House.

"I hope that the people responsible are caught and brought to justice as soon as possible," Culbertson added. "But first, our prayers and condolences to all involved. And I just wanted the folks to know that their city still looks very beautiful from space. I know it's very difficult for everybody in America right now, and I know folks are struggling very hard to to deal with this and recover from it. But the country still looks good, and, for New Yorkers, your city still looks great from up here."

Culbertson gave a more complete accounting of his thoughts in an open letter, which he published a day after the attacks.

"The world changed today. What I say or do is very minor compared to the significance of what happened to our country today when it was attacked," he wrote.

"It's horrible to see smoke pouring from wounds in your own country from such a fantastic vantage point," Culbertson added. "The dichotomy of being on a spacecraft dedicated to improving life on the Earth and watching life being destroyed by such willful, terrible acts is jolting to the psyche, no matter who you are."

Culbertson arrived at the ISS on Aug. 12, 2001 aboard the space shuttle Discovery along with cosmonauts Vladimir Dezhurov and Mikhail Tyurin. The trio comprised Expedition 3, the third-ever crewed mission to the orbiting lab, which ran through December of that year.

We're now up to Expedition 75, and there have been no breaks: The ISS has been continuously staffed by rotating astronaut crews since November 2000.

Expedition 3 was Culbertson's third and final spaceflight. He retired from NASA in August 2002 and went to work in the private sector. Among other roles, he led human spaceflight efforts at Orbital Sciences Corp., which built the Cygnus ISS resupply spacecraft. Cygnus still flies today, for the aerospace giant Northrop Grumman, which bought Orbital Sciences in 2018.

Culbertson, 77, retired from Northrop Grumman in 2018. He currently serves on the board of directors of the nonprofit Space Foundation, among other roles.

You can read more about Culbertson's experiences on NASA's dedicated 9/11 page. That page also outlines how the agency helped emergency managers assess the damage in New York City just after the attacks and discusses some of the ways NASA has honored 9/11 victims and their families over the years.

For example, NASA flew nearly 6,000 small American flags on the STS-108 mission of the space shuttle Endeavour, which launched on Dec. 5, 2001 and landed 12 days later.

"Students working out of Johnson Space Center in Houston assembled commemorative packages that included the space‑flown flags, which were then presented to victims' families," NASA officials wrote about the project. "Distribution began on June 14, 2002 — National Flag Day — during a ceremony at the American Museum of Natural History’s Rose Center for Earth and Space in New York."
