The Falcon 9 rocket was 30 seconds away from lifting off at 12:55 p.m. EST (1755 GMT) from Space Launch Complex 40 at the Cape Canaveral Space Force Station in Florida when SpaceX stopped the launch. The rocket is carrying the SXM-7 satellite for Sirius XM.
"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," SpaceX wrote in an update on Twitter. A Sunday launch attempt would lift off at 7:13 a.m. EST (1213 GMT).
SpaceX is launching the SXM-7 satellite for satellite radio provider Sirius XM on this mission. SXM-7 is a 15,432-lb. (7,000 kilograms) radio communications satellite designed to serve Sirius subscribers across the U.S., Canada and the Caribbean.
The Falcon 9 rocket for this mission is a veteran SpaceX booster making its 7th launch into space. It previously launched an uncrewed Crew Dragon test flight for NASA in 2019, the Radarsat constellation for Canada later that year, and then four Starlink satellite internet missions in 2020.
The SMX-7 mission will mark the second time SpaceX has launched a Falcon 9 for the seventh time.
