One week to launch for SpaceX's Crew-2
SpaceX is one week away from launching four astronauts into space for NASA to begin a months-long trek to the International Space Station.
A SpaceX Falcon 9 rocket will launch the astronauts on the Crew-2 mission for NASA on Thursday, April 22. Liftoff is set for 6:11 a.m. EDT (1011 GMT). The space agency will hold a Flight Readiness Review briefing today, April 15, at 7 p.m. EDT (2300 GMT) to discuss the mission. You can watch that live here and follow along at the top of this page.
The Crew-2 mission will launch from NASA's historic Pad 39A at the Kennedy Space Center in Cape Canaveral, Florida. A SpaceX Falcon 9 rocket and the Crew Dragon Endeavour, which launched SpaceX's first crewed flight for NASA (called Demo-2) in May 2020, will launch the mission.
Crew-2 will launch a four-person crew: NASA astronauts Shane Kimbrough, Megan McArthur, Japanese astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet. The four space travelers will join seven others aboard the station when they arrive at the station on April 23. Four of those crewmates launched on SpaceX's Crew-2 mission and will return to Earth on April 28. The other three arrived earlier this month on a Russian Soyuz to begin their own extended stay.

SpaceX is 'go' for Halloween Crew-3 launch
SpaceX and NASA have cleared the Crew Dragon spacecraft Endurance and its Falcon 9 rocket to launch four astronauts to the International Space Station on Halloween (Oct. 31) on the Crew-3 mission. The call came late last night after a Flight Readiness Review. You can read our full story by Mike Wall for details.
Liftoff remains set for early Sunday at 2:21 a.m. EDT (0621 GMT) from Pad 39A of NASA's Kennedy Space Center in Cape Canaveral, Florida.
SpaceX is working to wrap up one final issue before flight: a slight redesign of the Crew Dragon's toilet. In September, toilet problems during SpaceX's all-civilian Inspiration4 flight revealed that a tube leading to a urine storage tank had popped loose, allowing urine into a fan system instead of its intended tank.
For the Crew-3 flight, SpaceX is revamping the toilet system to include an all-welded structure that would prevent similar tube separations. Once SpaceX completes its work, NASA will have to sign off on the change, something that is expected in coming days.

SpaceX, NASA 'go' for Crew-3 astronaut launch
SpaceX and NASA are "go" to launch the Crew-3 astronaut mission to the International Space Station, mission officials announced late tonight.
The decision clears the way for SpaceX to launch four astronauts on a Falcon 9 rocket and Crew Dragon capsule at 9:03 p.m. EST (0203 GMT Nov. 11) from Pad 39A of NASA's Kennedy Space Center in Florida.
There is an 80% chance of good weather at launch time, according to a forecast from Space Launch Delta 45 at the Cape Canaveral Space Force Station near NASA's KSC spaceport.
The Crew-3 mission will launch NASA astronauts Raja Chari, Thomas Marshburn, Kayla Barron and European Space Agency astronaut Matthias Maurer to the space station on a six-month expedition. Their launch comes two days after the splashdown of SpaceX's Crew-2 mission for NASA.
On that Crew-2 flight, one of the parachutes on its Crew Dragon capsule was slow to inflate, but it was within tolerances (the Dragon capsule can land with only three parachutes, and did fully inflate before splashdown. The occurrence posed no issue for the Crew-3 launch, officials said.
About 6 hours before the Crew-3 launch, the International Space Station will have to fire its thrusters to dodge space debris leftover from a defunct Chinese satellite, but will be complete in time for launch, NASA officials said.
SpaceX Crew-3 Launch Webcast Begins

United Arab Emirates astronaut joins Crew-6
UAE astronaut Sultan AlNeyadi was announced Monday (July 25) as the fourth crew member of SpaceX's Crew-6 mission, which is expected to launch in 2023. AlNeyadi will be the first astronaut from an Arab nation to conduct a long-duration mission on the International Space Station. His seat was arranged through a previously disclosed agreement with Axiom Space.
AlNeyadi will join NASA astronauts Stephen Bowen and Woody Hoburg, who will serve as spacecraft commander and pilot, respectively, aboard Crew-6. A Roscosmos cosmonaut, Andrei Fedyaev, joined the crew this month following a seat swap deal between Russia's federal space agency and NASA to fly cosmonauts aboard private American vehicles, in exchange for U.S. Soyuz seats.

Possible SpaceX Crew-1 debris spotted in Australia
Charred material, possibly a remnant from a SpaceX spacecraft, was discovered in a sheep paddock near Dalgety, Australia. Witnesses in the region heard a "bang" July 9 local time. Weeks later, two region farmers came across large and unfamiliar pieces of hardware on their large properties.
SpaceX has not yet confirmed if the piece was a part of its Crew-1 Dragon spacecraft that splashed down successfully on May 2, 2021. That said, two space debris trackers suggest it was indeed from that mission, given that Dalgety was underneath the projected re-entry pathway of an unpressurized "trunk" piece of Dragon, jettisoned before re-entry.

SpaceX examines possible debris, addresses Crew-5 rocket damage
A SpaceX team is on the way to Australia to investigate possible space junk associated with a cargo "trunk" that detached from the Crew-1 spacecraft, burning up in the atmosphere July 8.
"We did get reports of debris from a trunk," Benjamin Reed, senior director of SpaceX's human spaceflight program, told reporters during a livestreamed NASA Crew-5 press briefing Thursday (Aug. 4).
He emphasized that SpaceX worked closely with NASA and the Federal Aviation Administration before the Crew-1 mission to minimize Crew Dragon debris, and that if the charred hardware is indeed SpaceX's, it came down exactly where predicted.
SpaceX is also working to address minor damage to the Crew-5 Falcon 9 first-stage booster, which came in contact with a bridge during transport. Reed said SpaceX is committed to making the fixes to address NASA's rigorous safety requirements. The damage delayed the launch until September.
SpaceX, NASA delay Crew-5 launch to avoid traffic jam
SpaceX and NASA plan to delay the next astronaut launch by four days, to no earlier than Oct. 3. The Crew-5 mission to the International Space Station was delayed from an initial target of Sept. 29.
"The date adjustment allows for extra separation with spacecraft traffic coming to and from the space station," agency officials said in the brief update, NASA announced in an update today (Aug. 25). The agency did not provide more details about their concerns regarding the traffic jam.

SpaceX likely lead provider for 2 new ISS private missions
With SpaceX the only company so far allowed by NASA to bring people to the International Space Station (ISS), it is likely in the lead to provide launch services for two new private missions.
NASA said Wednesday (Sept. 14) that it has asked private industry for proposals for two private ISS missions to run between late 2023 and 2024. SpaceX already has experience in providing such services, as its Falcon 9 rocket and Crew Dragon spacecraft sent the first all-private Axiom Space mission, called Ax-1, to the orbiting complex earlier this year.

NASA, SpaceX 'Go' for Crew-5 launch
NASA and SpaceX are pressing ahead with plans to launch the Crew-5 astronaut crew to the International Space Station despite three open issues for the launch team.
SpaceX and NASA gave the official "GO" for launch on Monday night during a Launch Readiness Review meeting. You can read our full story on that call from spaceflight editor Mike Wall. SpaceX rolled the Crew-5 Falcon 9 rocket to the launch pad over the weekend. Check out some of amazing photos from that event.
SpaceX is working three issues that need to be resolved for launch:
A thrust vector control actuator on one of the Crew-5 Falcon 9 rocket's 9 first-stange Merlin engines. It should be replaced by today.
A communications issue affecting the drone ship Just Read The Instructions affecting its station-keeping ability for the Falcon 9 booster's first stage landing.
A leak in a portable fire extinguisher on the Dragon capsule, which will be fixed with replacement parts.
SpaceX is confident it will be able to address all three open issues in time for launch. Meanwhile, the company is planning to launch two other missions, a Starlink flight from Vandenberg Space Force Base in California on Oct. 4, which will only lift off if the Crew-5 mission is delayed for some reason, and two telecom satellites from Florida on a different Falcon 9 rocket.

SpaceX Crew-5 Endurance Capsule en route to ISS
SpaceX's Crew-5 Dragon Endurance has begun its journey to the International Space Station after a smooth launch from Pad 39A at NASA's Kennedy Space Center in Florida. Read our full Crew-5 launch story.
Crew-5 astronauts Nicole Mann and Josh Cassada, both of NASA, and Soichi Wakata of Japan and Anna Kikina of Russia got the "go" to remove the SpaceX-issue space suits they work for launch as they begin the 35-hour trip to the International Space Station.
Inside Endurance, a small Albert Einstein doll is floating around as the zero gravity indicator for the crew to honor Einstein's "happiest thought."
"That thought was 'a person in freefall wouldn't feel their own weight,'" Cassada, Crew-5's pilot, said during a livestream broadcast from space. "That thought, along with some others that he built upon, led to general relativity and our understanding of gravitation and the curvature of space-time."
We're experiencing Einstein's happiest thought continuously as the International Space Station has been doing continuously for over20 years. On Crew-5, we call this little guy our freefall indicator. We're here to tell you there's plenty of gravity up here, in fact that's what's keeping us in orbit right now and preventing trip on the Crew Dragon from being a one-way trip."
Cassada then waxed a bit poetically.
"A little bit like life, we live in the same world, we live in the same universe. Sometimes we experience it in a very different way from our neighbors," he said. "If we can all keep that in mind, hopefully we can all continue to do absolutely amazing things, and do it together."
NASA, SpaceX Crew-5 post launch press conference now

'Watty burgers' and cosplay forged Crew-4's teamwork in orbit
Close teamwork is essential on the International Space Station, and the Crew-4 astronauts shared two strategies for forging that during a post-flight press conference Thursday (Oct. 20): food and cosplay.
Crew-4 mission specialist Jessica Watkins invented a special "Watty burger" so delicious that her spacecraft commander, Kjell Lindgren, created food challenges in orbit. "I became notorious for putting more food into a tortilla than was probably wise, or possible," Lindgren recalled. "One night, Bob [Farmer, a NASA astronaut] was witness to a triple-decker — I put an extra side in there — and he claimed I unhinged my jaw to be able to eat."
Meanwhile, Crew-4 astronaut and Expedition 67 commander Samantha Cristoforetti found herself in a thrift store on a spare time quest to replicate an iconic scene from the 1968 movie "2001: A Space Odyssey." "That is not something that I would buy for myself, normally," she said, "but it seemed to fit perfectly for that need."
Returned SpaceX Crew-4 astronauts have space station ideas
The SpaceX Crew-4 cohort of four astronauts, who returned to Earth on Oct. 14, have some great ideas for space station design after their recent mission on the International Space Station (ISS).
"I think we need to really start thinking out of the box on a lot of these things. But first and foremost, if we're going to do human exploration, you got to put the 'human' in the equation," said Crew-4 pilot and NASA astronaut Bob Farmer in a press conference Thursday (Oct. 20).

SpaceX plans to build fifth and final Crew Dragon for ISS missions
SpaceX plans to supply a fifth (and final) Crew Dragon for International Space Station astronaut missions "in the 2024 timeframe", officials said during a phone call last month ahead of the successful launch and docking of a cargo Dragon spacecraft in late November.
In September, NASA requested several more commercial crew missions from SpaceX, which Sarah Walker, director of Dragon mission management at SpaceX, called an "exciting commercial human spaceflight manifest" in a Nov. 18 briefing with reporters.
Some SpaceX Crew Dragon spacecraft are being used for private industry, including a November announcement that will see two Saudi astronauts go to the ISS aboard Axiom Space missions.
SpaceX Dragon will be 'lifeboat' if ISS crew requires it
A SpaceX Dragon capsule was modded this week to include an extra astronaut seat. On Wednesday (Jan. 18), NASA started moving agency astronaut Frank Rubio's seat liner from a Russian Soyuz spacecraft over to Endurance, the Dragon spacecraft that's flying SpaceX's ongoing Crew-5 mission for NASA.
The in-orbit changes to the International Space Station spacecraft were made in the wake of Soyuz losing its coolant last month following an apparent debris or micrometeoroid strike.

Scrub!
The planned Crew-6 launch attempt was scrubbed with less than 2.5 minutes left in the countdown on Feb. 27 due to a ground-system issue with the ignition fluid that helps light the Falcon 9 rocket's first-stage engines. The next possible launch opportunity will come Feb. 28 at 1:22 a.m. EST (0622 GTM).
Read our Crew-6 scrub story.
New launch date for Crew-6 on Thursday (March 2)
SpaceX and NASA have announced a tentative new launch date of Thursday, March 2 at 12:34 a.m. EST (0534 GMT) due to unfavorable weather on Tuesday (Feb. 28), which was the next possible opportunity following the scrub. Should the launch go on March 2, docking with the International Space Station is scheduled for Friday, March 3 at 1:11 a.m. EST (0611 GMT).
Less than T-2 days to SpaceX Crew-6 launch date
Pending review of the issue that held up a launch attempt Monday (Feb. 27), SpaceX and NASA are still targeting a new liftoff date of Thursday, March 2 at 12:34 a.m. EST (0534 GMT). We will carry coverage here on Space.com, via NASA Television.
NASA and SpaceX officials are planning a press conference to discuss results of the ongoing review, but have not yet announced timing. Should the launch go on March 2, docking with the International Space Station is scheduled for Friday, March 3 at 1:11 a.m. EST (0611 GMT).
SpaceX, NASA confirm Thursday (March 2) launch for Crew-6
A SpaceX Falcon 9 rocket will officially reattempt launch of the Crew-6 mission Thursday (March 2) at 12:34 a.m. EST (0534 GMT) and you can watch the event here at Space.com, courtesy of NASA Television. Weather conditions are 95% favorable for launch at NASA's Kennedy Space Center in coastal Florida.
"NASA's SpaceX Crew-6 mission is 'Go' for launch to the International Space Station following completion of a launch readiness review, weather briefing, and mission management meeting," agency officials wrote in a blog post Wednesday (March 1).
A launch attempt Monday (Feb. 27) to the International Space Station (ISS) had been called off 2.5 minutes before T-0 due to a ground-system issue, but NASA said the issue has been addressed.
SpaceX and NASA found a problem with ignition fluid, called triethylaluminum triethylboron or TEA-TEB, that sparks the oxidizer for the engines to turn on.
"During prelaunch, the TEA-TEB fluid?—which originates in a ground supply tank?— flows to the rocket's interface and back to a catch tank to remove gas from the ground plumbing," NASA officials wrote. "During engine start, the fluid then flows to the engines for ignition. Flow into the catch tank is one of several parameters used to determine that the fluid has been properly bled into the system."
A clogged ground filter reducing the flow to a TEA-TEB catch tank caused the issue and that filter has been replaced. The TEA-TEB nitrogen line was also purged with nitrogen and everything has been cleared for launch.
Following launch, Crew-6 and its four astronauts are scheduled to dock with the Harmony module at the ISS at 1:17 a.m. EST (0617 GMT) on Friday (March 3). Hatch opening is expected at 3:27 a.m. EST and the welcome ceremony at 3:40 a.m. EST. Space.com will also carry these events, courtesy of NASA.
Crew-6 launch stream has begun!
NASA's webcast of SpaceX's Crew-6 astronaut launch to the International Space Station is underway. The livestream began at 8:45 p.m. EST on Wednesday (March 1; 0145 GMT on March 2).

The crew members, who represent the space agencies of four different nations, entered a pair of black Tesla Model X’s with the license plates that read, “BYEEE.”
Crew-7 astronauts and cosmonaut arrive at the launchpad
The quartet of Crew-7 astronauts riding SpaceX Crew Dragon Endurance to the International Space Station (ISS), arrived at Launch Complex-39A (LC-39A) after a short ride in a pair of Tesla Model Xs, from the astronaut quarters at NASA's Kennedy Space Center, in Florida.
A quick pause to admire their launch vehicle, members of Crew-7 will ride the launch-tower elevator close to the top, and walk across the crew access arm to get strapped in and prepared for their 3:27 a.m. EDT (0727 GMT) instantaneous launch window.
Crew-7 astronauts strap into Crew Dragon Endurance
After traversing the lengthy crew access arm attached to the tower at Launch Complex-39A (LC-39A) and signing their names to the gantry bulkhead – as is tradition before departing the planet – Crew-7 astronauts have strapped into their seats aboard Crew Dragon Endurance with the help of the SpaceX “ninja” team, and are undergoing seal checks prior to closing the Endurance hatch.
Crew Dragon Endurance hatch closed for launch
SpaceX closed the hatch to Crew Dragon Endurance at T-02:05:00, as final leak checks were performed and Crew-7 astronauts prepare for their launch to space. Communications checks with mission control and crew members are also underway. A launch escape system check was performed following hatch closure.
T-1 hour to liftoff
SpaceX and NASA are now 1 hour away from the instantaneous 3:27 a.m. EDT (0727 GMT) launch window.
Polling for teams in mission control for “go/no go” station status checks will begin at T–45 minutes. Preparations for fast-fill fueling will begin shortly. A “go” poll across the board will keep the early morning launch on track, with crew access arm gantry retraction being the launches next major milestone, at T–40. The crew will then arm the launch escape system in preparation for fueling.
Retraction of the crew access arm and launch escape system arming
Following unanimous “go’s” from the SpaceX launch control team, mission controllers have proceeded with gantry retraction. The crew access arm at Launch Complex-39A has been swung away from Crew Dragon Endurance, as Crew-7 astronauts onboard inch closer to liftoff.
The astronauts of Crew-7 have closed the visors on their spacesuits. Mission controllers have ordered the arming of Dragon’s launch escape system, which serves as a system for keeping the astronauts safe in case of emergency once fueling has begun, and through the end of their mission.
T-20 minutes to launch: Fueling underway
SpaceX is fueling the the Falcon 9 rocket for tonight's Crew Dragon launch with 20 minutes remaining in the launch pad.
The launch team is watching a sensor issue that has come up, but it currently is not expected to affect the launch. All systems are GO for the 3:27 a.m. EDT (0727 GMT) launch.
T-10 minutes to launch
SpaceX is now T-10 to launch and counting. This will be the 1st flight of the Falcon 9 1st stage powering this launch.
SpaceX reports it is proceeding with the launch countdown as fueling continues. Launch controllers are still studying a potential sensor issue to determine if it may be an issue for launch.
Liftoff still set for 3:27 a.m. EDT (0727 GMT).
Falcon 9 Stage 1 RP-1 fueling complete
SpaceX reports its Falcon 9 first stage is fully filled with its RP-1 propellant for launch. Stage 2 fueling is will continue to just before liftoff. Both first and 2nd stages are also being fueled with their liquid oxygen supply needed for flight.

Crew-7 Dragon docks at space station
Crew-7 Dragon Endurance has successfully docked with the space-facing port on the International Space Station's Harmony module at 9:16 a.m. ET (1316 GMT).
"Guys, thank you for the welcome," Crew-7 commander Jasmin Moghbeli radioed the ISS crew as the station played a traditional ship's bell to welcome them.
Docking occurred as the station and Dragon were sailing 261 miles above Australia. Now that docking soft capture is complete, the station's docking ring will retract so a series of hooks and latches can secure the Dragon to the station. Once leak checks are complete, the crew will then be able to open the hatches between their craft and the ISS and enter the station.
Crew-7 opens Dragon hatch to ISS
Crew-7 commander Jasmin Moghbeli has confirmed that the Dragon Endurance capsule's docking hatch to the International Space Station was opened a 10:58 a.m. EDT (1458 GMT), clearing their path to enter the station.
Moghbeli was the first to enter, followed by Andreas Mogensen of ESA, Satoshi Furukawa of JAXA and Konstantin Borisov of Roscosmos. The four crewmembers join seven others already aboard the station, raising its population to 11.
After a series of safety briefings, the joint crew held a welcome ceremony to end their docking activities.
SpaceX, NASA delay Crew-6 return to Earth
NASA and SpaceX have pushed back the return to Earth for four Crew-6 astronauts due to bad weather at their splashdown site off the coast of Florida.
Originally scheduled to undock from the International Space Station early on Sept. 2 and land overnight on Sept. 3, the astronauts will now undock no earlier than Sunday, Sept. 3, at 7:05 a.m. EDT (1105 GMT), with splashdown to follow at 12:07 a.m. (0407 GMT) the following day.

NASA Chief to hold Crew-8 briefing
NASA will hold a press conference today at 10:30 a.m. EST (1530 GMT) to give an update on the upcoming launch of four astronauts to the International Space Station on the Crew-8 mission.
NASA Administrator Bill Nelson will head the briefing, which will also include mission officials and experts. Here is who will be speaking in the panel:
NASA Administrator Bill Nelson
NASA Associate Administrator Jim Free
Joel Montalbano, manager, International Space Station Program
Steve Stich, manager, Commercial Crew Program
Crew-8 will launch NASA astronauts NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, to the ISS on March 1 atop a SpaceX Falcon 9 rocket and the Dragon capsule Endeavour. Liftoff is set for 12:04 a.m. EST (0504 GMT) from Pad 39A of NASA's Kennedy Space Center.
NASA stresses safety for Crew-8 launch
NASA leadership underscored that safety comes above all else as the agency prepares to launch three NASA astronauts and one Roscosmos cosmonaut to the International Space Station atop a SpaceX Falcon 9 rocket.
In a briefing on Wednesday (Feb. 28) at Kennedy Space Center in Florida, NASA Administrator Bill Nelson stressed that no matter how routine commercial launches with SpaceX and other providers may appear to the public, the agency learned its lesson with the 1986 space shuttle Challenger disaster and approaches every mission with the utmost caution.
"Every time we launch, it's white-knuckle time — and especially when humans are on top," Nelson said during the briefing. "We never want to get in to the frame of mind that it's so routine that it's like getting in your car and taking a Sunday afternoon drive."
Crew-8's liftoff is currently scheduled for 12:04 a.m. EST (0504 GMT) on Friday (March 1) . You can watch it live here at Space.com when the time comes.

It's launch day for Crew-8
It's launch day for NASA's Crew-8 mission to the International Space Station on a SpaceX Falcon 9 rocket and Crew Dragon spacecraft.
SpaceX is counting down toward a planned launch from NASA's Pad 39A at the Kennedy Space Center at 11:16 p.m. EST (0416 GMT), but the weather outlook is looking grim.
Currently, there is only a 40% chance of good weather at launch time, with SpaceX requiring clear conditions for both the rocket as well as offshore seas for recovery teams in the unlikely event of a launch abort that sends the Dragon capsule parachuting into the sea.
SpaceX does have the option to try again on Sunday, March 3, at 10:53 p.m. EST (0353 GMT), if needed, the company has said.
Crew-8 will launch four astronauts on a six-month mission to the International Space Station. That crew includes NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, with Roscosmos cosmonaut Alexander Grebenkin of Russia rounding out the team.
NASA's livestream of the launch will begin at about 7:15 p.m. EST (0015 GMT).
Crew-8 launch webcast begin, 4 hours to launch
SpaceX is just under 4 hours away from the launch of its Crew-8 astronaut mission for a NASA and everything appears on track for an 11:16 p.m. EST (0416 GMT) launch tonight. You can watch the launch live on this page.
The four Crew-8 astronauts - NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin - have suited up in their SpaceX spacesuits and are completing final leak checks. Once complete, they'll head out of NASA's Neil Armstrong Operations and Checkout Building and take Tesla electric cars to their Pad 39A launch pad.
The astronauts will launch on a Falcon 9 rocket and the Crew Dragon Endeavour, a Dragon capsule that is making its fifth flight with the Crew-8 mission.
SCRUB! SpaceX postpones Crew-8 launch
SpaceX flight controllers called off tonight's Crew-8 astronaut launch due to high ascent winds expected at liftoff time. SpaceX's next opportunity to launch Crew-8 is now Sunday, March 3, at 10:53 p.m. EST (0353 GMT on March 4).
The call came as the four Crew-8 astronauts were all suited up in their SpaceX spacesuits, but they had not yet departed for the launch pad. The astronauts will now doff their suits and return to their crew quarters to rest up for their next attempt.
"Basically, it will be kind of like Groundhog Day," NASA astronaut Raja Chari said during commentary on NASA TV. "Because they didn't come all the way out to the pad, it's going to be a lot easier on the crew. They are going to have the opportunity to get a lot more rest than they would otherwise.
NASA's livestream of the Crew-8 astronaut launch will begin at 6:45 p.m. EST (2345 GMT). You can watch live on this page.
It's Launch Day (again) for Crew-8
The four astronauts of SpaceX's Crew-8 astronaut mission for NASA will again attempt to launch to the International Space Station today after bad weather delayed an attempt on Saturday.
A SpaceX Falcon 9 rocket is now scheduled to launch Crew-8 from NASA's Pad 39A at the Kennedy Space Center in Florida at 10:53 p.m. EST (0353 GMT). There is a 75% chance of good weather for tonight's launch. You'll be able to watch live via NASA's livestream starting at 6:45 p.m. EST (2345 GMT). SpaceX's livestream on X (formerly Twitter) will begin at about 9:53 p.m. EST.5gt
Crew-8 astronauts suiting up
The four astronauts of SpaceX's Crew-8 mission to the International Space Station have begun suiting up for their planned launch tonight (March 3). That liftoff is scheduled for 10:53 p.m. EST (0353 GMT on March 4) from NASA's Kennedy Space Center in Florida, and it looks like Mother Nature will cooperate: There's currently a 75% chance that the weather will be good enough to allow launch.
Playing cards before launch
The Crew-8 astronauts played a brief card game with the deputy chief of NASA's Astronaut Office about 3.5 hours before their planned launch today (March 3). The game is a tradition, according to commentators on NASA TV: They play until the mission commander loses, so he uses up all of his bad luck before launch.
Walkout!
The four Crew-8 astronauts left the Neil Armstrong Operations and Checkout Building at NASA's Kennedy Space Center (KSC) at around 7:35 p.m. EST tonight (March 3; 0035 GMT on March 4). They walked out to wave goodbye to friends and family, then got in two Teslas for the roughly 20-minute journey to KSC's Pad 39A.
At the pad
The two Teslas carrying the four Crew-8 astronauts reached Pad 39A at NASA's Kennedy Space Center tonight (March 3) at 7:51 p.m. EST (0051 GMT on March 4), three hours before their planned launch atop a SpaceX Falcon 9 rocket.
Ingress
The Crew-8 astronauts have boarded their spacecraft. The quartet entered their SpaceX Crew Dragon capsule, called Endeavour, around 8 p.m. EST tonight (March 3; 0100 GMT on March 4). So far, everything is going smoothly ahead of Crew-8's planned launch at 10:53 p.m. EST (0353 GMT on March 4).
Hatch closure
Crew Dragon Endeavour's side hatch was sealed at 8:50 p.m. EST on March 3 (0150 GMT on March 4), another major milestone toward the Crew-8 astronaut launch to the International Space Station. Everything remains on track for liftoff at 10:53 p.m. EST tonight (0353 GMT on March 4).
Crew Dragon Endeavour's launch escape system is armed
At around 10:15 p.m. EST tonight (March 3; 0315 GMT on March 4), mission teams retracted the crew access arm at Kennedy Space Center's Pad 39A and armed the launch escape system of the Crew Dragon Endeavour, notching two big milestones ahead of the liftoff of SpaceX's Crew-8 astronaut mission to the International Space Station. Launch is scheduled for 10:53 p.m. EST (0353 GMT on March 4).
Propellant load is underway
Teams began loading propellant (kerosene) and oxidizer (liquid oxygen) into Crew-8's Falcon 9 rocket at 10:18 p.m. EST tonight (March 3; 10318 GMT on March 4), 35 minutes before the astronaut mission's planned launch.
Everything continues going smoothly, though mission teams did notice a small crack in the seal in the hatch of Crew-8's capsule, named Endeavour. This crack is not believed to be a serious problem, but analyses are still underway.
Liftoff!
The Crew-8 mission lifted off on time tonight (March 3) from NASA's Kennedy Space Center in Florida. If all goes according to plan, the mission's Endeavour capsule will rendezvous with the International Space Station around 3 a.m. EST (0800 GMT) on Tuesday (March 5).
Crew-8 prepares to dock
The four Crew-8 astronauts are on their way to dock at the International Space Station.
After a spectacular nighttime liftoff from NASA's Kennedy Space Center on Sunday (March 3), SpaceX's Crew Dragon Endeavour spacecraft entered Earth orbit ahead of its rendezvous with the space station.
Endeavour is scheduled to dock at the forward-facing port of the ISS's Harmony module at 3 a.m. ET (0800 GMT) on Tuesday (March 5). Hatch opening will follow at about 4:45 a.m. (0945 GMT) if the docking schedule holds, followed by a welcome ceremony aboard the station. You can watch docking here at Space.com courtesy of NASA, when the time comes.

SpaceX to send Crew-9 to space on Aug. 18 after Falcon 9 failure
NASA and SpaceX are looking to launch the Crew-9 mission around the middle of this month.
Crew-9, SpaceX's next astronaut launch to the International Space Station (ISS) for NASA, is currently set for Aug. 18. The four astronauts that will be on board are commander Zena Cardman, pilot Nick Hague, mission specialist Stephanie Wilson and mission specialist Alexsandr Gorbunov, of Russia's space agency Roscosmos.
The mission still has to get final launch approval from NASA, after the second stage of a SpaceX Falcon 9 rocket failed on July 11 due to an oxygen leak. While the rocket has been cleared for flight and recently resumed uncrewed launches of SpaceX's Starlink satellites, NASA wants to ensure the vehicle is safe for crews ahead of the target Aug. 18 launch date.

SpaceX Crew-9 may bring home Starliner astronauts
Boeing Starliner may not bring its first astronauts home after all.
NASA officials, absent a representative from Boeing, updated reporters today (Aug. 7) about how troubleshooting Starliner's undocking and landing may affect the next SpaceX astronaut flight to the International Space Station.
Starliner has faced a lot of difficulties since launching its first astronaut mission, most especially after 5 of its 28 reaction control thrusters (RCS) misfired during docking with the ISS on June 6. Work on the matter is ongoing, and as NASA revealed yesterday (Aug. 6), it will require the next launch to the ISS to wait.
Crew-9, SpaceX's ninth operational flight to the ISS designed for four astronauts, will now launch Sept. 24 instead of Aug. 18. That's because NASA may send only two astronauts up on Crew-9, and bring the Starliner astronauts with the two returning crew sometime around February 2025.
