SpaceX and NASA are nearing completion of the software assurance process, and SpaceX is submitting a request to the Cape Canaveral Air Force Station for a May 19th launch target with a backup on May 22nd.
Thus far, no issues have been uncovered during this process, but with a mission of this complexity we want to be extremely diligent.
The launch of the first Dragon spacecraft to fly to ISS had been scheduled for May 7 with a backup date of May 10. A new three-man crew is set to launch aboard a Soyuz rocket on May 14, necessitating a longer delay for the SpaceX Dragon mission once it missed the May 10 launch date.
UPDATE: William Gerstenmaier, NASA associate administrator for Human Exploration and Operations, issued the following statement later on Friday:
“After additional reviews and discussions between the SpaceX and NASA teams, we are in a position to proceed toward this important launch. The teamwork provided by these teams is phenomenal. There are a few remaining open items but we are ready to support SpaceX for its new launch date of May 19.”
