The process of flight crew health stabilization is a routine part of final preparations for all missions to the space station. Spending the final two weeks before liftoff in quarantine will help ensure Crew-4 members are healthy and to protect the astronauts already on the space station.
Crew members can choose to quarantine at home if they are able to maintain quarantine conditions prior to travel to Kennedy. If quarantining at home is not possible – for example, if a household member can’t maintain quarantine because of job or school commitments – crew members have the option of living in the Astronaut Quarantine Facility at Johnson Space Center until they leave for Kennedy Space Center.
Additional safeguards have been added since the start of the coronavirus pandemic. Anyone who will come on site or interact with the crew during the quarantine period will be screened for temperature and symptoms. Lindgren, Hines, Watkins, and Cristoforetti will be tested twice for the virus as a precaution, as well as anyone who comes in direct, close contact with the crew.
NASA’s SpaceX Crew-4 mission is the fourth crew rotation flight to the ISS as part of NASA’s Commercial Crew Program. Crew-4 is targeted to launch no earlier than Thursday, April 21, on a new SpaceX Crew Dragon, named Freedom, atop the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Mission operations teams will be closely monitoring the weather and operational timelines related to the Axiom Mission 1, NASA’s first Private Astronaut Mission to the space station. Additional adjustments to the Crew-4 launch date may be required based on weather and Crew-4 vehicle readiness.
Crew-4 will arrive at the space station for 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. Also on station are Roscosmos cosmonauts Oleg Artemyev, Denis Matveev, and Sergey Korsakov who flew to the station on a Soyuz spacecraft on March 18, 2022.

NASA’s SpaceX Crew-4 team – consisting of NASA astronauts Kjell Lindgren, Bob Hines, Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti – have been busy getting ready for their upcoming mission to the International Space Station. The mission is scheduled to launch Friday, April 15, from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

During recent training at SpaceX headquarters in Hawthorne, California, the crew participated in simulations focused on undocking and departing from the space station. All four astronauts practiced in a high-fidelity simulator of SpaceX’s Dragon capsule, complete with flight-realistic hardware, displays, and seats. Each astronaut gained experience suiting up and configuring the spacecraft for departure. Commander Lindgren and pilot Hines took their places in the center seats, with access to flight displays they’ll use to monitor the spacecraft’s status and, if needed, take manual control of the spacecraft.
Astronaut crews regularly train for all phases of flight, using simulations to practice normal operations and respond to any unexpected issues. These simulations typically include multiple “runs” for a given day, with crew and flight controllers practicing a specific phase of the mission. Using simulated data to train personnel, simulations introduce system failures and other challenges to give teams the opportunity to prepare for and understand potential anomalies that could arise during a spaceflight, all while arming the crew with the skills needed for effectively overcoming these challenges.

While at Kennedy Space Center for emergency preparedness training, the crew visited the launch tower at Launch Complex 39A and trained on the emergency egress system, which employs slide wire baskets that enable crew and personnel to safely and quickly evacuate from the launch tower in the event of an emergency.
To become more familiar with recovery operations, the astronauts found their sea legs aboard SpaceX’s Dragon recovery vessels that will be used by joint SpaceX and NASA teams to pick up the crew following splashdown at the end of their mission. Two identical vessels cover potential landing zones off of the coast of Florida. The astronauts also toured one of SpaceX’s hangars where Falcon 9 rockets are refurbished and prepared for flight.
The crew is scheduled for a science expedition aboard the International Space Station, living and working as part of orbiting laboratory’s Expeditions 67 and 68. Crew-4 will be the fourth crew rotation mission with SpaceX, and fifth crewed flight overall including the Demo-2 flight test, for NASA’s Commercial Crew Program.

Good morning and welcome to live blog coverage of NASA’s SpaceX Crew-2 mission — the second crew rotation flight and the first with two international crew members on a U.S. commercial spacecraft with astronauts to the space station. Launch is scheduled for 5:49 a.m. EDT from the historic Launch Complex 39A at Kennedy Space Center.
Here at Kennedy, a SpaceX Falcon 9 rocket, topped by the company’s Crew Dragon spacecraft — named Endeavour by the crew — awaits liftoff early this morning. NASA astronauts Shane Kimbrough and Megan McArthur, along with JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet, will fly to the International Space Station for a six-month science mission.
The countdown is proceeding according to schedule. At the Florida spaceport’s Neil A. Armstrong Operations and Checkout Building, the astronauts have eaten and will undergo medical checks and get a weather briefing before suiting up.
Stay with us as the countdown continues. We’ll keep you updated on the key milestones throughout this historic mission. Starting at 1:30 a.m. EDT, on NASA Television and the agency’s website, there will be continuous live coverage of important Crew-2 activities.

With the countdown clock and Launch Pad 39A serving as a backdrop, acting NASA Administrator Steve Jurczyk participated in a briefing for the Crew-2 mission at the agency’s Kennedy Space Center in Florida on Wednesday, April 21, at 8:30 a.m. EDT.
The briefing came after Crew-2’s launch was rescheduled to Friday, April 23, at 5:49 a.m. EDT, because of unfavorable weather conditions along the flight path. Although conditions around the launch site were expected to be favorable for a Thursday, April 22, liftoff, mission teams also must consider conditions along the flight path and recovery area in the unlikely event of a launch escape.
“We’re now scheduled for ‘go’ on Friday and the crew is ready,” said Acting NASA Administrator Steve Jurczyk. “I could not be more proud of the Commercial Crew Program, the SpaceX and NASA teams, and what they’ve been able to do to enable reliable, safe, effective transportation to and from space. We are looking forward to a great launch.”
Crew-2 is the second crew rotation flight of a U.S. commercial spacecraft with astronauts to the space station and the first carrying two international crew members. Mission astronauts Shane Kimbrough and Megan McArthur of NASA, along with JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide and ESA (European Space Agency) astronaut Thomas Pesquet, will head to the International Space Station for a six-month science mission in the Crew Dragon spacecraft, which will launch on the SpaceX Falcon 9 rocket from Launch Complex 39A.
“On behalf of JAXA, I’d like to express my gratitude to the launch team,” said Hiroshi Sasaki, vice president and director general, JAXA’s Human Spaceflight Technology Directorate. “Last night, I spoke with Akihiko Hoshide, and he is ready for launch. I am excited that two Japanese astronauts – Akihiko Hoshide and Soichi Noguchi – will meet together at the International Space Station. I’m looking forward to the Crew-2 launch and wishing them great success.”
The crew will conduct science and maintenance during their six-month stay aboard the space station and will return no earlier than Oct. 31. Adding more crew members aboard the microgravity laboratory increases the time available for scientific activities. The November 2020 addition of the Crew-1 astronauts more than doubled crew hours spent on science research and support activities, and Crew-2 will continue the important investigations and technology demonstrations that are preparing for future Artemis missions to the Moon, helping us improve our understanding of Earth’s climate, and improving life on our home planet.
An important scientific focus on this expedition is continuing a series of Tissue Chips in Space studies. Tissue chips are small models of human organs containing multiple cell types that behave much the same as they do in the body. Another important element of Crew-2’s mission is augmenting the station’s solar power system by installing the first pair of six new ISS Roll-out Solar Arrays (iROSA).
“It’s an exciting time for us,” said Frank de Winne, manager, International Space Station Program. “We will have much more time to do research, science, but also technology development that we will need for the future of the Artemis program and for the future exploration of our solar system.”
Crew Dragon will deliver more than 500 pounds of cargo, as well as new science hardware and experiments, including CHIME, a university student-led investigation to study possible causes for suppressed immune response in microgravity.
For an April 23 launch, the U.S. Space Force 45th Weather Squadron predicts a 90% chance of favorable weather conditions at the launch pad for liftoff based on Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns for the launch area will be liftoff winds. Conditions also are expected to improve along the flight path and recovery area for the mission.
NASA TV coverage of Crew-2 launch preparations and liftoff will begin at 1:30 a.m. Friday, April 23. The Crew Dragon is scheduled to dock to the space station Saturday, April 24, at approximately 5:10 a.m. EDT.
