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.
Launch of NASA’s SpaceX Crew-2 mission with astronauts to the International Space Station is on track for Friday, April 23, at 5:49 a.m. EDT. The SpaceX Falcon 9 rocket with Crew Dragon spacecraft will lift off from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
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. 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.
For an April 23 launch, the U.S. Space Force 45th Weather Squadron continues to predict 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 flight through precipitation from isolated, low-topped coastal showers and onshore flow. Conditions continue to improve along the flight path and recovery area for the mission.
Today, Thursday, April 22, is Earth Day. To commemorate this day, NASA is hosting Earth Day in Space. Singer-songwriterShawn Mendes will join five astronauts living and working aboard the International Space to discuss how we’re all #ConnectedByEarth, asking questions from young people around the world about Earth Day, climate change and how the astronauts study Earth from space.
The event will feature NASA astronaut Mark Vande Hei, who recently arrived to the space station aboard a Soyuz, joining NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japan Aerospace Exploration Agency astronaut Soichi Noguchi, the Crew-1 team who arrived last November. It will air live on NASA Television, the NASA app, and the agency’s YouTube channel and website at 11 a.m. EDT April 22.
The Crew-1 astronauts are scheduled to depart the space station at 7:05 a.m. Wednesday, April 28. They will participate in their final news conference aboard the microgravity laboratory at 12:30 p.m. EDT Monday, April 26, about their upcoming return to Earth. Media wishing to participate by telephone must call NASA’s Johnson Space Center’s newsroom at 281-483-5111 to RSVP no later than 5 p.m. Friday, April 23. The news conference will air live on NASA Television, the NASA app, and the agency’s website. Those following the briefing on social media may ask questions using #AskNASA.
Crew-1 worked on a number of experiments as part of Expedition 64 to the International Space Station, including tissue chips that mimic the structure and function of human organs to understand the role of microgravity on human health and diseases, and translate those findings to improve human health on Earth. Astronauts also grew radishes in different types of light and soils as part of ongoing efforts to produce food in space and tested a new system to remove heat from spacesuits.
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.
NASA and SpaceX now are targeting 5:49 a.m. EDT Friday, April 23, for the launch of the agency’s Crew-2 mission to the International Space Station due to unfavorable weather conditions along the flight path on Thursday.
Although conditions around the launch site were expected to be favorable for liftoff, mission teams also must consider conditions along the flight path and recovery area in the unlikely event of a launch escape.

Early this morning, Sunday, April 18, Crew-2 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, completed a countdown dress rehearsal of the launch day events.
Alongside their launch teams, the crew members are preparing for their mission to the International Space Station aboard a SpaceX Crew Dragon, named Endeavour, secured atop the company’s Falcon 9 rocket. Crew-2 is the second crew rotation flight of the SpaceX Crew Dragon and the first with two international partners in support of the agency’s Commercial Crew Program.
Kimbrough, McArthur, Hoshide, and Pesquet began their day in the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building. They put on their black-and-white SpaceX spacesuits, took the elevator down to the ground level and exited through a pair of double doors, where Tesla Model Xs waited to transport them to the launch pad. With smiles and waves, they climbed in for the 20-minute ride to Launch Complex 39A.
The Falcon 9 rocket and Crew Dragon spacecraft moved to the launch pad and into the vertical launch position on Friday, April 16. All four astronauts entered the Crew Dragon by way of the pad’s Crew Access Arm and checked their communications systems before the hatch was closed. The rehearsal concluded about 45 minutes prior to the scheduled launch time; lift off is set for Thursday, April 22 at 6:11 a.m. EDT.
NASA and SpaceX managers are meeting today to assess the readiness for the Crew-2 mission. The Flight Readiness Review at the agency’s Kennedy Space Center in Florida also is assessing readiness for the Crew-1 return scheduled for April 28. The traditional FRR focuses on the preparedness of SpaceX’s crew transportation system, the International Space Station, and its international partners to support the flight, and the certification of flight readiness.
NASA will hold a media teleconference later today, no earlier than 6 p.m. EDT, April 15, about an hour after the conclusion of the review to discuss the outcome. You can listen to the news conference streamed live on NASA’s website. Media may ask questions via phone only and should contact the Kennedy newsroom for connection details no later than 5 p.m.
SpaceX’s Crew Dragon spacecraft, named Endeavour, arrived at Kennedy Space Center’s Launch Complex 39A on Monday, April 12, after making the trek from its processing facility at nearby Cape Canaveral Air Force Station in Florida. The space capsule was placed atop the SpaceX Falcon 9 rocket and is scheduled to be transported to the pad later today, Thursday, April 15, and raised to the vertical launch position.
