NASA and SpaceX now are targeting no earlier than 5:26 a.m. EDT Saturday, April 23, for the launch of the agency’s Crew-4 mission to the International Space Station from NASA’s Kennedy Space Center in Florida. The date adjustment provides mission teams time to complete final prelaunch processing for the Crew-4 mission following the April 8 launch of Axiom Mission 1 (Ax-1) to the space station.

Mission teams continue to monitor operational timelines with ongoing space station activities, including upcoming spacewalks and the return of Ax-1 crew members. The weather forecast remains a watch item to ensure safe recovery and launch operations for crew missions. The Crew-4 date also provides three consecutive launch opportunities with backups on Sunday, April 24, and Monday, April 25.

The agency’s flight readiness review will be held on Friday, April 15, at Kennedy. The review will focus on the preparedness of SpaceX’s crew transportation system, the International Space Station, and its international partners to support the flight, as well as the certification of flight readiness.

Following the review, NASA will hold a media teleconference to discuss the status to launch at approximately 5:30 p.m. or one hour after the review concludes. While the teleconference will not be televised, media may call in to ask questions via phone. Contact the Kennedy newsroom no later than 4 p.m. on Friday, April 15, for connection details.

Participants in the teleconference will include:

  • Kathy Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters
  • Steve Stich, manager, Commercial Crew Program, Kennedy
  • Joel Montalbano, manager, International Space Station, NASA’s Johnson Space Center
  • Zeb Scoville, flight director, Flight Operations Directorate, Johnson
  • Jared Metter, director, Flight Reliability, SpaceX
  • Frank De Winne, program manager, International Space Station, ESA (European Space Agency)

The Crew-4 flight will carry NASA astronauts Kjell Lindgren, mission commander, Robert Hines, pilot, and Jessica Watkins, mission specialist and ESA astronaut Samantha Cristoforetti, who will serve as a mission specialist, to the space station for a science expedition mission. The astronauts will fly a new Crew Dragon spacecraft, named Freedom, on a flight proven Falcon 9 rocket.

Crew-3 astronauts will splash down off the coast of Florida following a short handover with Crew-4 on the space station.

SpaceX Crew-4 Astronauts Enter Quarantine for Mission to Space Station

NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti, entered their official quarantine period beginning Thursday, April 7, in preparation for their flight to the International Space Station on NASA’s SpaceX Crew-4 mission.

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 Trains for Upcoming Mission

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.
