LAUNCH OF CREW-11 TO ISS, Aug 1, 2025, KSC, 11:43 am ET (coverage begins 7:35 am ET)

Update, July 31, 11:00 pm ET:  NASA confirms they will try again tomorrow, August 1, at 11:43 am ET but “conditions around the launch pad are forecast at 75% favorable for liftoff. However, conditions along the flight path of Dragon remain a watch item. Acceptable weather conditions at both the launch site and along the Dragon flight path are required for a “go” for liftoff.”  NASA coverage begins at 7:35 am ET on NASA+, and Amazon Prime.

Update, July 31:  The launch was scrubbed 1 minute and 7 seconds before launch because of weather.

NASA tweeted that tomorrow is the next opportunity and gave the start time for live coverage, but it’s not clear if that is an official statement that they will, in fact, try again tomorrow. A number of backup opportunities are available over the next week.

Today’s launch attempt has been scrubbed due to weather. Our next Crew-11 launch attempt will be at 11:43am ET (1543 UTC) Friday, Aug. 1. Our coverage will begin at 7:35am ET (1135 UTC).

Update, July 24: Launch is still targeted for July 31, 2025 at 12:09 pm ET. NASA coverage will begin at 8:00 am ET on NASA+, Netflix, and Amazon Prime.  A post-launch press conference is scheduled for 1:30 pm ET. See our separate entry for details.  If launch takes place as planned, Crew-11 will arrive at the ISS on August 2. See our separate entry for details.

Original Entry: NASA is targeting July 31, 2025 at 12:09 pm ET as the No Earlier Than (NET) date for the launch of Crew-11 to the International Space Station. Backup dates are August 1, 2, 3, 5, 6, 7.

If launch is on July 31, it will be a 39-hour trip to the ISS with arrival on August 2 at 3:00 pm ET. That’s close to the 40-hour limit for which Crew Dragon can sustain a crew. NASA said during a July 10 news conference that a space station reboost is coming up that could “trip over that limit” and they will shift to August 1 if needed.

Crew-11’s four crew members are:

• Zena Cardman, commander (NASA)
• Mike Fincke, pilot (NASA)
• Kimiya Yui, mission specialist (JAXA)
• Oleg Plotonov, mission specialist (Roscosmos)
