SpaceX vehicle to depart ISS for California water landing: How to watch NASA coverage
Update: NASA and SpaceX are now planning for the Dragon to undock at 12:05 p.m. ET Friday, May 23. The vehicle would then land at 1:45 a.m. ET Sunday, May 25 off the coast of California.
A SpaceX vehicle that has spent about a month docked at the International Space Station on a resupply mission is due to depart within a matter of hours.
NASA will provide live coverage as the uncrewed spacecraft begins its return voyage Thursday, May 22. The Dragon capsule, developed by Elon Musk's commercial spaceflight company to deliver cargo and crews to the orbital outpost, will then embark on a long voyage ending with a splashdown landing Friday, May 23, off the coast of California.
The vehicle arrived in April with plenty of food, equipment and other supplies for the seven astronauts currently living aboard the station. And it's not leaving emptyhanded: When it undocks, it will be loaded up with scientific research samples and hardware bound for Earth.
Here's what to know about the resupply mission and how to watch the U.S. space agency's coverage of the Dragon's departure:
For 25 years, the International Space Station has been stationed in low-Earth orbit, typically about 250 miles high, where it has been home to astronauts from all over the world.
The orbital laboratory is operated through a global partnership of space agencies, including NASA, Roscosmos, the European Space Agency, the Japan Aerospace Exploration Agency (JAXA) and the Canadian Space Agency (CSA).
More than 280 spacefarers from 23 countries have visited the International Space Station, including 169 from the United States alone, according to NASA. Bigger than a six-bedroom house, the outpost has six sleeping quarters, two bathrooms, a gym and a 360-degree view bay window.
As of now, seven members of Expedition 73, including three Americans, are living aboard the ISS – conducting scientific research and working to maintain the station.
The crew members aboard the station spent time Wednesday, May 21, loading and securing a variety of cargo inside the Dragon spacecraft ahead of its scheduled departure.
The Dragon has spent 30 days docked to the Harmony module, a port and passageway onto the station facing away from Earth, after arriving April 22 with nearly 6,700 pounds of supplies. The spacecraft launched April 21 on a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center near Cape Canaveral, Florida, for SpaceX's 32nd commercial resupply services mission.
Standing nearly 27 feet tall and about 13 feet wide, the Dragon is one of four cargo spacecraft that deliver science experiments and other cargo to the space station on a regular basis. Dragon capsules can also carry up to seven astronauts into orbit, though most of SpaceX's Crew missions, which are contracted with NASA, feature a contingent of four.
The Dragon is due to undock at about 12:05 p.m. ET Thursday, May 22, from the Harmony module before firing its thrusters to move away from the station. The departure will be under command by SpaceX's Mission Control in Hawthorne, California.
NASA will provide live coverage of the undocking beginning at 11:45 a.m. ET Thursday on its streaming service, NASA+.
After re-entering Earth's atmosphere, the spacecraft will splash down on Friday, May 23, off the coast of California. While NASA will post updates on the agency's space station blog, it will not provide a livestream of the water landing.

The Company Helping Build the Next Space Station Is Launching to the ISS
America's most expensive government housing project cost north of $100 billion, took 13 years to build, and has been continuously occupied since 2000—yet most of the time no more than six people live there. That's because the residence in question is the International Space Station (ISS), a million-pound orbital outpost with a footprint larger than a football field and the habitable volume of a six-bedroom house, circling the Earth 250 miles overhead. Over the past 25 years, on-board astronauts have done yeoman's work in the station's six laboratory modules. But the ISS is getting old, and NASA and the 14 other partner nations that built, maintain, and operate it have plans to de-orbit it by 2030, sending it tumbling down through the atmosphere for a controlled splashdown in a remote patch of ocean. Before the ISS dies, however, it will help birth its own replacement—one that will be built and launched by the private sector, with the new modules constructed by Houston-based Axiom Space, and launch services and the Dragon spacecraft provided by SpaceX. Over the past three years, Axiom has launched three private, paying crews of four astronauts to the ISS, preparatory to the commencement of station construction. On June 10 it plans to launch its fourth mission, straightforwardly dubbed Axiom Mission 4 (Ax-4)—one more milestone on the road to the first new space station module going aloft in 2027. 'It's important for the U.S. to maintain a human presence in space, and that's why I think the Axiom station is so important,' says former NASA astronaut and Axiom's director of human space flight Peggy Whitson, who commanded Axiom Mission 2 (Ax-2) and will command Ax-4. 'We've got to get the [new] station up and running before the ISS is decommissioned. That push for … expansion in space is important from a technology perspective [and] from a space power perspective.' Speedy but significant science Ax-4's mission will be a relatively brief 14 days—an eyeblink compared to the six months to a year that the station's long-term residents stay aboard. But as with the earlier Axiom flights, none of which went beyond 18 days, the crew will be performing a lot of solid science in the time they're aloft. 'This particular mission will comprise 60 scientific studies and activities representing 31 countries, including the U.S., India, Poland, Hungary, Saudi Arabia, Nigeria, the UAE, and nations across Europe,' said Allen Flynt, Axiom's chief of mission services, at a May 20 press conference. 'This will be the most research…conducted on an Axiom space mission aboard the International Space Station to date.' Among the experiments to be performed will be studies of the effect of microgravity on the brain—crucial information to have in the run-up to long-term missions to the moon and Mars—as well as similar investigations of how the heart and muscles adapt to space. Also on the research manifest will be studies of eye-hand coordination, and even how to manage blood glucose in space, opening the door to future travel by astronauts with insulin-dependent diabetes. Perhaps the most ambitious work, however, will involve testing various drugs to treat cancer—work that can be dramatically accelerated if it takes place in space. 'People always say, 'Why do you go to space to look at cancer?'' says Whitson. 'Well, cancer cells proliferate faster [in microgravity], so in a very short period of time you can give them a drug and see if it's slowing them down. If you shut them off you can effectively say, 'Hey this is a very promising drug.'' During Ax-2, the crew was specifically studying colorectal cancer. This time around they will be looking at triple-negative breast cancer —an aggressive form of the disease—and should be able to finish the study even in the short time they'll be aloft. Collaboration is key The mission won't be just about the science, but about building global partnerships that go beyond the international suite of experiments the crew will perform. Axiom Space might be a U.S. company, but Whitson will be the only American aboard when Ax-4 lifts off. Joining her will be crewmembers Shubhansa Shukla, from India; Sławosz Uznański-Wiśniewski of Poland; and Tibor Kapu of Hungary. The mission comes after a long wait for all three countries. A Hungarian has not been in space since 2009, when paying space tourist Charles Simonyi traveled to the ISS aboard a Russian Soyuz spacecraft. The last Indian citizen in space was Rakesh Sharma, who was aboard another Soyuz, which docked with Russia's Salyut 7 space station in 1984. For Poland the wait has been longest of all, dating back to 1978, when Mirosław Hermaszewski launched aboard a Soyuz. 'Private astronaut missions are a great opportunity for our member states to fly more astronauts and do more experiments aboard the International Space Station,' said Sergio Palumberi, mission manager with the European Space Agency (ESA)—which includes Hungary and Poland—at the May 20 press conference. 'ESA will be executing 17 science investigations and technological demonstrations.' 'This is more than a space mission for us,' said Orsolya Ferencz, Hungary's ministerial commissioner of space research. 'It is a strategic national effort, an expression of Hungary's commitment to sovereignty in critical technological fields and to secure a place in the rapidly evolving space economy.' The four new arrivals aboard Ax-4 will join an equally international crew of seven already living on the ISS; they include three astronauts from the U.S., three cosmonauts from Russia, and one astronaut from Japan—Takuya Onishi, who is currently station commander. During Axiom-4's trips to and from space, Whitson will be in command of her three-person crew, but when they're aboard the station, she will cede most of her authority to Onishi. 'I'm responsible for my crew and our activities on the ISS, but the crew that's already up there will be responsible for the station as a whole,' Whitson says. 'It wouldn't be appropriate for a short-term person to take over.' Building the next 'ISS' The 14-day Ax-4 mission is being flown with an eye toward a more distant goal. This flight and the previous three have been dress rehearsals both for crews and for Axiom's onsite mission control, providing critical experience working in orbit and managing activities from the ground. That patient practice will be put to use in 2027 when the first Axiom space station module goes aloft and docks with the ISS. Over the course of the following three years, four more modules will be sent up and dock with the one already there, with the new cluster serving as a semi-autonomous space station budding from the larger existing one. In 2030, not long before the ISS is deorbited, the Axiom station will undock and become its own free-floating lab. The first module, known as the payload, power, and thermal module (PPTM), will, as its name suggests, provide power, temperature control, and storage space for the new station. Following the PPTM will come one airlock module, two habitat modules, and a research and manufacturing module (RMF), where the onboard science will be performed. The RMF also includes a windowed enclosure similar to but much larger than the ISS's cupola, providing 360-degree views of the Earth below and the surrounding space. 'It's way bigger than the cupola,' says Whitson. 'It's going to be an immersive experience, where you can get your whole body inside. It will be like doing a spacewalk without having to put a spacesuit on.' Axiom does not rule out adding more modules still down the line, especially as the company attracts private sector and government customers willing to pay to have experiments run and hardware tested in microgravity. The space community has gotten spoiled in the past 25 years, with a rotating corps of international astronauts always at work, always in orbit, making their homes aboard the ISS. The station may not attract the global excitement that the old Mercury, Gemini, and Apollo missions did, but we will surely miss it when it's gone. Axiom Space is prepared to fill that void.

Axiom Space's record-setter to lead astronauts from 3 nations on private mission
Peggy Whitson has spent nearly two years of her life in space as an Axiom Space employee and former NASA astronaut. Next week she'll lead a mission with three men representing countries that haven't sent anyone to space in more than four decades. Whitson, 65, will command the Ax-4 mission targeting liftoff as early as 8:22 a.m. Tuesday from Kennedy Space Center's Launch Pad 39-A. It will transport three Axiom customers: one each from India and Hungary, whose seats were paid for by their governments, and one from Poland through the European Space Agency. Whitson flew three times for NASA before joining Axiom, for which she commanded the Ax-2 mission in 2023 and tallied more than 675 days in space. She holds the record for most time in space by a woman and most for any American. All four of her missions were to the International Space Station — as is the Ax-4 flight. 'For me, returning to space is always a special experience. Every mission is different,' she said during a call with media Tuesday. 'Every crew brings something new to the table. I've been incredibly impressed by the dedication and the work ethic and the passion of this team. 'It's been a joy to train alongside them and I'm looking forward to seeing them in microgravity.' That crew members are Shubhanshu Shukla of India, acting as mission pilot; mission specialist Sławosz Uznański of Poland, an ESA project astronaut; and mission specialist Tibor Kapu of Hungary. The quartet will climb aboard a new SpaceX Crew Dragon — which will get its official name once it reaches orbit — launching atop a Falcon 9 rocket on only the second human spaceflight of the year from Space Coast following the March launch of Crew-10. The Dragon is slated to dock with the space station Wednesday at 12:30 p.m. for a planned two-week stay during which crew members will participate in a heavy schedule of science experiments, technology demonstrations and media outreach. 'We'll be conducting research that spans biology, material and physical sciences as well as technology demonstrations,' Whitson said. 'We'll also be engaging with students around the world, sharing our experience and inspiring the next generation of explorers.' One science experiment she's most interested in could pave the way for people who are diabetic to travel into space. 'A person with diabetes can't fly in space because it's disqualifying and not considered to be safe, because we wouldn't know how their bodies would respond,' Whitson said. 'So if we have the appropriate technology to monitor the individuals, we feel that we can open up that door and that path for a lot of folks in the world and just open up space a little bit more.' Delving into a customer base of countries which don't have as much access to space is part of Axiom's business plan. For this mission, the three countries represented first flew to space with the Soviet Union as cosmonauts on Soyuz spacecraft, but nothing since 1984, although a Hungarian-American millionaire flew to the space station twice as a tourist in 2007 and 2009. The governments paid Axiom an undisclosed amount for their representatives' trip to the space station. It marks the third time it has flown government-sponsored passengers after its first trip to the station in 2022 had three men who paid $55 million each for their visit. Whitson's last trip on Ax-2 had just one private passenger who paid their own way. The Saudi Arabian government paid for the other two passengers. Since then, Axiom has focused on only government-sponsored customers. Ax-3 in 2024 had passengers from Italy, Turkey and Sweden. Similar to Uznański on this mission, the ESA paid for the Swedish customer even though the agency has access to the space station as a partner with NASA, Canada, Japan and Russia. The trio of space newcomers on this mission all spoke of it as opening up possibilities for their nations. 'I carry with me, not just instruments and equipment, but the hopes and dreams of a billion hearts,' said India's Shukla, who will perform seven experiments for research institutions from his nation. 'These experiments will pave the way for India's progress in microgravity science, and I'm proud to be the bridge between Earth and orbit for this pioneering research, balancing the scientific ambition with a rich cultural heritage.' Poland's Uznański noted that he will enjoy the view. 'I'm looking forward to floating in the cupola, which is our window back on Earth. I can't wait to see all the training places, and also our four countries from up there, but mostly to see Earth as a whole, as one planet, one home,' he said. Kapu will do 25 experiments for Hungary while also using half of his personal luggage space to bring something that pays homage to the first Hungarian who flew to space in 1978. 'There was a teddy bear which is wearing a cosmonaut space suit. This teddy bear is from a Hungarian TV show for kids,' he said, noting it went along for the ride nearly 50 years ago. 'I'm really proud to fly that again.' It won't be the only stuffed animal on the flight. The other is a swan called Joy, named by Kapu, that will function as the crew's 'zero-gravity indicator' — traditionally an object that lets astronauts know they've reached space as it begins to float around after launch. Whitson teased the swan's connection to the name reveal for the Crew Dragon capsule. The first four Crew Dragons were named Endeavour, Resilience, Endurance and Freedom. 'The reason we selected this one might become more obvious once you hear the name of the vehicle,' she said. 'You'll have to wait for that one.'

Japanese lunar lander crashes while attempting touchdown on the Moon
A private lunar lander from Japan crashed while attempting a touchdown on Friday, the latest casualty in the commercial rush to the Moon. Tokyo-based company ispace declared the mission a failure several hours after communication was lost with the lander. Flight controllers scrambled to gain contact, but were met with only silence and said they were concluding the mission. Communications ceased less than two minutes before the spacecraft's scheduled landing on the Moon with a mini rover. Until then, the descent from lunar orbit seemed to be going well. Takeshi Hakamada, ispace chief executive officer and founder, apologised to everyone who contributed to the mission, the second lunar strikeout for the company. Two years ago, the company's first moonshot ended in a crash landing, giving rise to the name Resilience for its successor lander. Resilience carried a rover with a shovel to gather lunar dirt as well as a Swedish artist's toy-size red house for placement on the Moon's dusty surface. Company officials said it was too soon to know whether the same problem doomed both missions. 'This is the second time that we were not able to land. So we really have to take it very seriously,' Mr Hakamada told reporters. He stressed the company would press ahead with more lunar missions. A preliminary analysis indicates the laser system for measuring the altitude did not work as planned and the lander descended too fast, officials said. 'Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface,' the company said in a written statement. Long the province of governments, the Moon became a target of private outfits in 2019, with more flops than successes along the way. Launched in January from Florida on a long, roundabout journey, Resilience entered lunar orbit last month. It shared a SpaceX ride with Firefly Aerospace's Blue Ghost, which reached the Moon faster and became the first private entity to successfully land there in March. Another US company, Intuitive Machines, arrived at the Moon a few days after Firefly. But the tall, spindly lander face-planted in a crater near the south pole and was declared dead within hours. Resilience was targeting the top of the Moon, a less treacherous place than the shadowy bottom. The ispace team chose a flat area with few boulders in Mare Frigoris or Sea of Cold, a long and narrow region full of craters and ancient lava flows that stretches across the near side's northern tier. Plans had called for the 7.5ft Resilience to beam back pictures within hours and for the lander to lower the piggybacking rover onto the lunar surface this weekend. Made of carbon fibre-reinforced plastic with four wheels, ispace's European-built rover — named Tenacious — sported a high-definition camera to scout out the area and a shovel to scoop up some lunar dirt for Nasa. The rover was going to stick close to the lander, going in circles at a speed of less than one inch per second.
