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.

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.
