Watch replay of Falcon 9 launch as seen from the press site

Liftoff from pad 40 at Cape Canaveral Space Force Station was set for 4:57 p.m. EST (2157 UTC) Sunday before the mission was scrubbed. SpaceX has not announce a new launch date or time for the mission.

Space station commander Chris Cassidy and Robert Behnken plan to float outside Friday for the first of up to four spacewalks needed to complete the replacement of aging batteries in the lab’s solar power system. NASA managers hope to get the work done in time for Behnken and crewmate Douglas Hurley to return to Earth aboard their Crew Dragon capsule by around Aug. 2, officials said Wednesday.

A European-built Ariane 5 rocket rolled out to a launch pad in the South American jungle Wednesday with a pair of commercial television broadcast satellites for AT&T and Eutelsat, setting the stage for liftoff Thursday evening.
