NASA’s SpaceX Crew-8 crew members are en route to the agency’s Kennedy Space Center in Florida to begin final launch preparations.
Crew-8 crewmates NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; Jeanette Epps, mission specialist; along with Roscosmos cosmonaut Alexander Grebenkin, mission specialist, departed by plane from Ellington Field near the agency’s Johnson Space Center in Houston, Texas, for the short flight to the Florida spaceport. The crew is expected to arrive at Kennedy’s Launch and Landing Facility this afternoon.
Crew-8 astronauts will be greeted upon their arrival by leaders from NASA for a brief welcome ceremony targeted for approximately 2 p.m. EST. The event is scheduled to stream live, if weather permits, on Kennedy’s YouTube, X, and Facebook accounts.
Meanwhile, NASA, SpaceX, and international partner representatives have gathered at Kennedy to participate in the agency’s Flight Readiness Review, which focuses on the preparedness of SpaceX’s crew transportation system, the space station, and its international partners to support the launch of Crew-8 and return of Crew-7. A teleconference is planned for later today, approximately one hour after the conclusion of the review. Be sure to follow along on our blog; additional details will be provided as the day progresses.
SpaceX Crew-8 is targeted to launch at 12:04 a.m. EST on Friday, March 1, to the International Space Station.
The crew that will soon launch to the International Space Station as part of NASA’s SpaceX Crew-7 mission arrived Sunday at the agency’s Kennedy Space Center in Florida to start final preparations for liftoff.
Crew members NASA astronaut Jasmin Moghbeli, commander; ESA (European Space Agency) astronaut Andreas Mogensen, pilot; and mission specialists JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov, landed via Gulfstream jet aircraft at the Launch and Landing Facility at Kennedy after departing from Ellington Field near the agency’s Johnson Space Center in Houston.
The flight crew will be greeted at arrival by leaders from NASA, JAXA, and ESA.

The event is scheduled to broadcast live, if weather permits, on NASA Television and the agency’s website. No teleconference option is available for this event.
Crew members are scheduled to lift off at 3:49 a.m. EDT Friday, Aug. 25, aboard a SpaceX Dragon spacecraft carried by a Falcon 9 rocket for a full duration mission to the space station as part of NASA’s Commercial Crew Program (CCP).
This is the seventh crew rotation flight and the eighth human spaceflight mission on SpaceX’s Dragon spacecraft to the International Space Station for CCP. Details about the mission and NASA’s Commercial Crew Program can be found by following the Crew-7 blog, the commercial crew blog, @commercial_crew on X, and commercial crew on Facebook.
The Psyche spacecraft completed its journey from NASA’s Jet Propulsion Laboratory (JPL) in Southern California to NASA’s Kennedy Space Center in Florida. First, it traveled to March Air Reserve Base, about 55 miles southeast of JPL, before flying cross-country aboard a C-17 aircraft to the Launch and Landing Facility (formerly the Shuttle Landing Facility) where crews offloaded the spacecraft. Over the next three months, the spacecraft will undergo additional preparations before launching aboard a SpaceX Falcon Heavy rocket on Aug. 1.
The Psyche spacecraft will use solar-electric propulsion to travel approximately 1.5 billion miles (2.4 billion kilometers) to rendezvous with its namesake asteroid in 2026. This will make it the first spacecraft to use Hall-effect thrusters beyond the orbit of the Moon. This thruster technology traps electrons in a magnetic field and uses them to ionize onboard propellant, expending much less propellant than equivalent chemical rockets. Psyche also carries three scientific instruments: an imager, magnetometer, and a gamma ray and neutron spectrometer.
The unique, metal-rich Psyche asteroid may be part of the core of a planetesimal, a building block of rocky planets in our solar system. Learning more about the asteroid could tell us more about how our own planet formed and help answer fundamental questions about Earth’s own metal core and the formation of our solar system.
The launch of Psyche will include two secondary payloads, NASA’s Deep Space Optical Communications (DSOC) technical demonstration, which is attached to the spacecraft as a separate experiment and the Janus spacecraft. DSOC will perform the agency’s first demonstration of optical communications beyond the Earth-Moon system, and will use lasers to send data at a higher rate than typical spacecraft radio communications. Janus is two small spacecraft that will study two different binary asteroids (two asteroids that orbit each other) to understand the formation and evolution of these objects.
The Psyche mission is led by Arizona State University. JPL, which is managed for NASA by Caltech in Pasadena, California, is responsible for mission’s overall management, system engineering, integration and testing, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. NASA’s Launch Services Program (LSP), based at Kennedy, is managing the launch. Psyche will be the 14th mission in the agency’s Discovery program and LSP’s 100th primary mission. Numerous international, university, and commercial partners are part of the Psyche team.
NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti are on their way to the International Space Station, following the picture-perfect launch of the agency’s SpaceX Crew-4 mission. SpaceX’s Crew Dragon spacecraft, named Freedom by the crew, launched atop the company’s Falcon 9 rocket from Kennedy Space Center’s Launch Complex 39A in Florida at 3:52 a.m. EDT.
“This is our fourth crew rotation flight – it’s kind of hard to believe,” said Steve Stich, manager, Commercial Crew Program, NASA’s Johnson Space Center in Houston. “It seems like Demo-2 was just yesterday, and it’s exciting to be here. We had a really clean countdown today – the Falcon 9 rocket did great; the Dragon vehicle did great. It was great to see the crew get in. You could tell they were excited to start their flight off.”
Upon their arrival at the space station, the Crew-4 astronauts will be greeted by NASA astronauts of the Expedition 67 crew already on board. During their six-month stay aboard the microgravity laboratory, Lindgren, Hines, Watkins, and Cristoforetti will join the Expedition 67 crew in conducting a number of science and research investigations.
The Crew-4 astronauts will conduct new and exciting scientific research in areas such as materials science, health technologies, and plant science to prepare for human exploration beyond low-Earth orbit and benefit life on Earth. Experiments will include studies on the aging of immune systems, organic material concrete alternatives, and cardiorespiratory effects during and after long-duration exposure to microgravity. These are just some of the more than 200 science experiments and technology demonstrations that will take place during their mission.
Launching alongside the crew in the Dragon capsule is an investigation that seeks to restore meaningful vision to people suffering from retinal degenerative diseases like retinitis pigmentosa and macular degeneration. The Protein-Based Artificial Retina Manufacturing experiment tests the manufacturing of artificial retinas or retinal implants in microgravity, where it is expected their production could be optimized.
Also traveling to space aboard the Crew Dragon are Smart-Tex shirts as part of the German Space Agency (DLR) investigation called Wireless Compose-2. The shirts are fitted with sensors, wiring, and a communications module to wirelessly transmit data to a base station. The shirt is designed to monitor cardiovascular activity like relative blood pressure and can provide details about heart contraction rate and valve opening and closing times – something normally accessible only through sonography or CT scans. These kinds of wearable technologies could be used to monitor health throughout a long-duration space exploration mission and could lead to a more flexible implementation of this technology in health monitoring equipment on Earth.
Crew-4 is NASA’s fourth crew rotation mission with SpaceX for the agency’s Commercial Crew Program. Lindgren and Cristoforetti have previously traveled to the International Space Station, while it will be the first trip for Hines and Watkins. Crew-4 astronauts are slated to arrive at the space station today, April 27, with docking targeted for 8:15 p.m. EDT. Following docking and hatch opening, a welcoming ceremony is planned for 2:40 a.m. EDT.
Coverage of Crew-4’s arrival to the station will air live on NASA Television and the agency’s website, beginning with docking at 8:15 p.m. EDT.
Earlier on Tuesday, April 26, NASA Administrator Bill Nelson and senior NASA leadership addressed members of the media during a briefing held at the agency’s Kennedy Space Center in Florida for NASA’s SpaceX Crew-4 mission, now less than a day away.
“Flying safely with crew means that you’ve got to do it one step at a time,” said Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters. “So, tomorrow morning, we’re hoping that you’ll get to see a really, really beautiful step, and we’ll get our crew safely to orbit.”
Lindgren and Hines were assigned to the Crew-4 mission in February 2021 and began working and training on SpaceX’s next-generation human spacecraft and for their stay aboard the space station. Cristoforetti was assigned to the mission in March 2021 and Watkins was added as the fourth crew member in November 2021.
The Crew-4 mission continues NASA’s efforts to restore and maintain American leadership in human spaceflight. Regular commercial crew rotation missions enable NASA to continue the important research and technology investigations taking place aboard the station. Such research benefits people on Earth and lays the groundwork for future exploration beyond low-Earth orbit, starting with the agency’s Artemis missions, which includes landing the first woman and person of color on the lunar surface.
The SpaceX Falcon 9 rocket and Crew Dragon spacecraft, which the crew has named Freedom, are scheduled to lift off at 3:52 a.m. EDT on Wednesday, April 27. Just over 17 hours after launch, the crew is expected to arrive at the orbiting laboratory. Docking is planned for approximately 8:15 p.m. EDT on Wednesday, April 27.
Weather officials with the U.S. Space Force’s 45th Weather Squadron are predicting an 90% chance of favorable weather conditions for launch – this is derived from Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns are cumulus cloud and flight through precipitation rules.
For more than 21 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration to the Moon and Mars. The station’s design requires humans living aboard to maintain it, operate it, and upgrade it; thus, International Space Station operations, including commercial resupply and commercial crew, are essential to the mission.
Live coverage of launch preparations and liftoff will begin at 12 a.m. EDT on Wednesday, April 27, on NASA Television, the NASA app, and the agency’s website.
NASA’s SpaceX Crew-4 launch is targeted at 3:52 a.m. EDT Wednesday, April 27, to the International Space Station from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
The U.S. Space Force 45th Weather Squadron predicts a 90% chance of favorable weather conditions at the launch pad for liftoff of the Crew-4 mission based on Falcon 9 Crew Dragon launch weather criteria.

On April 20, the SpaceX Falcon 9 rocket that will launch the Dragon Freedom capsule and Crew-4 astronauts to the International Space Station surpassed a key milestone ahead of launch. While vertical on the launch pad at Kennedy Space Center’s Launch Complex 39A in Florida, the rocket’s nine Merlin first-stage engines roared to life for seven seconds, completing the routine but critical integrated static fire test.
The Crew-4 mission will carry Mission Commander Kjell Lindgren, Pilot Robert Hines, and Mission Specialist Jessica Watkins, as well as ESA (European Space Agency) astronaut Samantha Cristoforetti, who will also serve as a mission specialist, to the space station for a six-month science mission.
The SpaceX Falcon 9 rocket, with Crew Dragon atop, rolled out to the launch pad on April 19, at Kennedy Space Center in Florida in preparation for NASA’s Crew-4 launch. The rocket is now in a vertical position at Kennedy’s Launch Pad 39A and underwent a successful dry dress rehearsal in the early morning hours of April 20 with the launch team and crewmembers.
The mission will fly a new Crew Dragon, which crew members have named Freedom. Mission Commander Lindgren tweeted the significance of the name: “The name celebrates a fundamental human right, and the industry and innovation that emanate from the unencumbered human spirit.” The spacecraft’s name also recalls Freedom 7, the spacecraft that carried Alan Shepard as the first American launched into space on May 5, 1961 aboard NASA’s Mercury-Redstone 3.
The SpaceX Dragon Freedom spacecraft for NASA’s Crew-4 mission is now mated to the Falcon 9 rocket that will launch it on its flight to the International Space Station.
On Sunday, April 17, the day after teams transported the spacecraft from SpaceX’s processing facility at Cape Canaveral Space Force Station, Florida, into the hangar at nearby Kennedy Space Center’s Launch Complex 39A, the space capsule was attached to the rocket in a horizontal position.
The launch vehicle – with Dragon atop – was rolled out to the launch pad and it will be raised to a vertical position today, April 19, in preparation for launch. Liftoff of the Falcon 9 is scheduled for 5:26 a.m. EDT Saturday, April 23.
The Falcon 9 will accelerate Dragon to an orbital velocity of 17,500 mph prior to spacecraft separation and rendezvous and docking with the space station. This will be the fourth mission for this Falcon 9, which previously launched SpaceX’s 22nd commercial resupply services mission and Crew-3 for NASA, as well as the Turkish communications satellite, Turksat-5B. Flying crew on a fourth-flight booster will be a first for the Commercial Crew Program and a huge accomplishment for the program and industry.
Crew-4’s arrival to the orbiting laboratory is planned for around 6 a.m. EDT Sunday, April 24, followed by a short overlap with NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, and ESA astronaut Matthias Maurer, who flew to the station as part of the agency’s SpaceX Crew-3 mission in November 2021.
Tune in to NASA TV or the agency’s website for live coverage of mission activities, beginning Friday at 9:30 p.m. with the prelaunch news conference. Launch day coverage, which also can be found here, starts Saturday at 1:45 a.m. EDT.
Media may call in to ask the crew questions ahead of their upcoming launch to the International Space Station. Contact the Kennedy newsroom for details on how to participate.
Housed inside the Neil Armstrong Operations and Checkout (O&C) Building, the crew quarters are where the astronauts remain while awaiting launch once they arrive at the Florida spaceport. The facility dates back to the Apollo Program and was also used for missions under the Space Shuttle Program. Inside the crew quarters are 23 bedrooms – each with its own bathroom – and the iconic suit room, where astronauts are helped into their spacesuits before exiting the O&C and making the short journey to the launch pad.
Crew-4 astronauts Lindgren, Hines, and Watkins, and Cristoforetti are scheduled to lift off aboard a Falcon 9 rocket and Crew Dragon spacecraft from Kennedy’s Launch Complex 39A on Saturday, April 23. Launch is targeted for 5:26 a.m. EDT, and just over 24 hours later, they will arrive at the orbiting laboratory for a short overlap with the astronauts who flew to the station as part of NASA’s SpaceX Crew-3 mission in November 2021.
Return of Crew-3 astronauts Raja Chari, Tom Marshburn, Kayla Barron, and Matthias Maurer is planned for late April, with a splashdown of Crew Dragon Endurance at one of seven landing zones off the coast of Florida. Crew-4 astronauts will conduct various experiments as part of their science mission, living and working as part of what is expected to be a 7-member crew.
