For NASA’s SpaceX Crew-8 launch, targeted at 10:53 p.m. EST tonight, the U.S. Space Force’s 45th Weather Squadron predicts a 75% chance of favorable weather conditions at the launch pad for liftoff. The primary weather concerns for the launch area are flight through precipitation and the anvil cloud rule.

The Dragon spacecraft carrying NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and Jeanette Epps, as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin, will launch to the International Space Station on the SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida as part of NASA’s Commercial Crew Program.

NASA’s live coverage of Crew-8 activities begins at 6:45 p.m. EST on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Follow along for details about the mission and NASA’s Commercial Crew Program on the Crew-8 blog, the commercial crew blog, X, and Facebook.

NASA’s SpaceX Crew-8 mission NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and mission specialist Jeanette Epps, as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin, are in the suit room in the astronaut crew quarters inside Kennedy Space Center’s Neil A. Armstrong Operations and Checkout Building.

A team of SpaceX suit technicians will help them as they put on their custom-fitted spacesuits and check for leaks. Designed for safety and functionality, the spacesuits supply pressurization, protecting the crew from potential depressurization, and a port located on the thigh connects to life support systems, including air and power. Also included in the suits are touchscreen-compatible gloves and a flame-resistant outer layer.

Watch now on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website, where NASA is providing live coverage of key milestones leading up to launch and through ascent following liftoff.

Good evening and welcome to live coverage of NASA’s SpaceX Crew-8 mission – the eighth crew rotation flight and the ninth human spaceflight mission on SpaceX’s Dragon spacecraft to the International Space Station for NASA’s Commercial Crew Program.

Launch weather officers from the U.S. Space’s Force 45th Weather Squadron predict a 40% chance of favorable weather conditions at the launch pad for liftoff. The primary weather concerns for the launch area are flight through precipitation and the thick cloud cover.

Launch is scheduled for 11:16 p.m. EST on Saturday, March 2, from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

Here at Kennedy, a SpaceX Falcon 9 rocket, topped by the company’s Dragon spacecraft, named Endeavour, awaits liftoff just after midnight. NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; Jeanette Epps, mission specialist; along with Roscosmos cosmonaut Alexander Grebenkin, mission specialist, will fly to the space station aboard Dragon, which previously flew NASA’s SpaceX Demo Mission-2, Crew-2 and Crew-6, in addition to Axiom Mission 1, the first commercial astronaut mission to the microgravity laboratory.

The countdown is proceeding according to schedule. At Kennedy’s Neil A. Armstrong Operations and Checkout Building, the astronauts have eaten and will undergo medical checks and get a final weather briefing before suiting up.

Starting at 7:15 p.m. EST, on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website there will be continuous live coverage of important Crew-8 activities.

Stay with us as the countdown continues. We’ll keep you updated on the key milestones throughout this mission. Details about the mission and NASA’s Commercial Crew Program can be found by following the Crew-8 blog, the commercial crew blog, X, and Facebook.

Launch weather officers with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 40% chance of favorable weather conditions for the launch of NASA’s SpaceX Crew-8 mission at 11:16 p.m. EST Saturday, March 2, from the agency’s Kennedy Space Center in Florida.

A weather front across Central Florida over the next several days will bring significant cloud cover, isolated rain showers, and occasionally gusty winds. The primary weather concerns at launch will be isolated showers and thick clouds associated with the stalled front.

The Dragon spacecraft carrying NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and Jeanette Epps, mission specialist; as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin, will launch to the International Space Station on the SpaceX Falcon 9 rocket from Kennedy’s Launch Complex 39A as part of NASA’s Commercial Crew Program. The crew remains in quarantine after NASA and SpaceX selected the updated launch opportunity due to unfavorable weather conditions forecast along the Dragon’s ascent corridor during earlier opportunities. In the unlikely case of an abort during launch or the flight of Dragon, the wind and wave conditions must be within acceptable conditions for the safe recovery of the crew and spacecraft.

NASA and SpaceX now are targeting 11:16 p.m. EST Saturday, March 2, for the launch of the agency’s Crew-8 mission to the International Space Station. Joint teams selected the updated launch opportunity due to unfavorable weather conditions forecast for Friday, March 1, in offshore areas along the flight track of the Dragon spacecraft. High wind and waves along the eastern seaboard have been observed and are forecast to continue through Saturday morning. In the unlikely case of an abort during launch or the flight of Dragon, the wind and wave conditions must be within acceptable conditions for the safe recovery of the crew and spacecraft.

The live broadcast of the mission – including liftoff and postlaunch milestones – will air on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website at 7:15 p.m. EST. Docking coverage will begin at 11:30 a.m. on Sunday, March 3, for a docking scheduled for approximately 2:10 p.m.

We’ll keep you updated on the key milestones throughout this mission. Details about the mission and NASA’s Commercial Crew Program can be found by following the Crew-8 blog, the commercial crew blog, X, and Facebook.
