Live coverage: Atlas 5 countdown and launch journal

NASA and SpaceX officials are moving forward with preparations to launch the next commercial Crew Dragon mission to the International Space Station next week after a Flight Readiness Review Thursday, pending a final evaluation of a discovery by SpaceX that it has potentially been loading slightly more propellant than expected into its Falcon 9 rockets.

Concerns over an unspecified part flying on the upper stages of United Launch Alliance’s rockets have delayed the launch of a GPS satellite on a Delta 4 booster from July 25 to no earlier than Aug. 22. The same issue has also delayed an Atlas 5 launch.

The Crew Dragon Endeavour was originally set to undock from the International Space Station back in September, but was stalled by a pair of hurricanes and other weather events. Undocking happened 5:05 p.m. EDT (2105 UTC) on Oct. 23, setting up splashdown at 3:23 a.m. EDT (0725 UTC) on Friday.
