Update: NASA and SpaceX are standing down from the Friday, August 25, launch opportunity for the agency’s Crew-7 mission to the International Space Station. Launch now is targeted at 3:27 a.m. Saturday, August 26, for SpaceX’s seventh crew rotation mission to the microgravity laboratory for NASA.
NASA and SpaceX have greenlit the Crew-7 mission for launch on August 25, after reviewing the rocket and spacecraft readiness. Crew preparations are on track, potential space debris is being monitored, and there’s a 90% favorable weather forecast for the launch.
NASA, SpaceX, and international partners have completed the launch readiness review for the agency’s Crew-7 mission to the International Space Station (ISS). Crew-7 managers gathered at NASA’s Kennedy Space Center in Florida at 9 p.m. EDT Wednesday to review the SpaceX Falcon 9 rocket and Dragon spacecraft readiness and decided launch is “Go” for liftoff to the space station. Launch now is targeted for 3:50 a.m. EDT Friday, August 25, from Kennedy’s Launch Complex 39A. If needed, a backup launch opportunity is available at 3:27 a.m. Saturday, August 26.
Rocket & Spacecraft Review
On Wednesday, rocket and ground systems engineering teams completed the detailed data reviews following the integrated static fire of the Falcon 9 rocket conducted the day before at Launch Complex 39A. Falcon 9 performance was normal, resulting in a successful full duration static fire of all nine Merlin first-stage engines.
Operations teams are not tracking any major issues with Falcon 9 or the Dragon spacecraft. NASA and SpaceX spent Wednesday working toward final launch readiness, with remaining work expected to be completed ahead of launch.
Debris Monitoring & Crew Preparation
The International Space Station Program is closely monitoring the potential need for a debris avoidance maneuver early afternoon on Thursday, August 24, for the orbital outpost. Space station mission control trajectory teams are tracking the debris and determining whether a short-duration burn of the station’s thrusters would be required.
If needed, the maneuver is not expected to impact the planned arrival of the Roscosmos ISS Progress cargo spacecraft, which is also on Thursday. More information will be provided as orbital trajectory teams review the data and determine whether the debris would fly in the vicinity of the space station requiring a change in the station’s altitude.
Rehearsal Activities
On Tuesday, Crew-7 NASA astronaut Jasmin Moghbeli, commander; ESA (European Space Agency) astronaut Andreas Mogensen, pilot; and mission specialists JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov participated in a rehearsal of launch day activities in preparation for the upcoming Crew-7 launch.
Rehearsal began with launch teams assisting Crew-7 crewmates into their SpaceX spacesuits inside the Astronaut Crew Quarters at Kennedy’s Neil A. Armstrong Operations and Checkout Building – just as they will on launch day. Next, the crew took the elevator down to the ground floor and exited the building’s double doors, where Tesla Model X vehicles were waiting to drive them the short distance to the launch site.
After they arrived at the launch pad, Moghbeli, Mogensen, Furukawa, and Borisov rode the launch tower’s elevator up to the crew access arm – the walkway they will use to enter their Dragon spacecraft, named Endurance. Once securely seated inside, the crew members checked their communications systems and performed seat rotation and suit leak checks. The rehearsal concluded with closure of the spacecraft’s side hatch, which normally occurs about one hour and 25 minutes before liftoff.
Weather Forecast & Broadcast Info
Forecasters with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 90% chance of favorable weather conditions for launch, with the cumulus cloud rule serving as the primary weather concern.
Starting at 11:45 p.m. EDT on Thursday, August 24, the live broadcast of the mission – including liftoff and postlaunch milestones – will air on NASA Television and the agency’s website.
