Some days you’re the bug, other days you’re the windshield.

The scheduled Wednesday launch of the Crew-10 mission to the International Space Station was scrubbed last night with a little more than forty six minutes left on the countdown clock. The delay stemmed from a malfunction in the hydraulic system of a ground support clamp arm attached to the Falcon 9 rocket, located at SpaceX’s Launch Complex 39A at Kennedy Space Center in Florida.

Crew Safe And Still In Florida

The crew—comprising NASA astronauts Anne McClain and Nichole Ayers, JAXA astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov—departed the Dragon spacecraft following the cancellation and will remain in Florida for the time being awaiting a new launch window.

The earliest rescheduled launch window is now set for no sooner than Friday, March 14th at 7:06 PM ET in an instantaneous window. That date is dependant on remediations of the hydraulic issue at the launch pad. At this time, the Falcon 9 vehicle itself and the Crew Dragon the astronauts will fly aboard is in good condition.

Weather

Weatherwise, the U.S. Space Force 45th Weather Squadron has not released a new Launch Mission Execution forecast for tomorrow. General forecasts for the Cape are showing a minimal chance of rain with easterly winds between 5-10 MPH with gusts not being a great deal higher than that. Keep in mind that the general forecasts do not consider launch criteria and cover much larger area than the ascent corridor at and above LC-39A, so the 45th may have a different outlook on the probability of acceptable conditions.

Another consideration will be winds and seas along the ascent corridor. That must be within acceptable conditions. Reliable forecasts for winds at the altitudes Falcon 9 will be at are not available at this time. Bottom line: wait for the 45th Weather Squadron’s forecast to draw any conclusions about weather conditions for the launch.

Should the Crew-10 mission proceed on March 14, the preceding Crew-9 team—consisting of NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, alongside Roscosmos cosmonaut Aleksandr Gorbunov—would undock from the space station NET Tuesday, March 18. That timeline remains contingent on suitable weather conditions at the designated splashdown zones off Florida’s coast and may change over the next few days.
