The launch window for the Falcon 9 rocket SXM-7, which is carrying a Sirius XM satellite, was pushed up to today at 10:22 a.m. CST being the earliest to a launch window to 12:21 p.m. CST from the Cape Canaveral Space Force Station, Florida. SpaceX had two delays on Friday, and then finally decided to suspend its launch until today due to the countdown clock being stopped at 30 seconds to launch with no published reason indicated.. . .Enjoy!
Standing down from today’s launch attempt to perform additional ground system checkouts; teams are working toward no earlier than Sunday, December 13 for next launch attempt of SXM-7
