— SpaceX postponed the latest launch of a new Starlink satellite fleet again Saturday (July 11) citing the need for more checks of the mission's Falcon 9 rocket. .

The California-based rocket builder planned to launch 57 Starlink satellites andtwo BlackSky Global Earth-observing satellites from Florida at 10:54 a.m.

"Standing down from today's launch of the tenth Starlink mission to allow time for more checkouts; team is working to identify the next launch opportunity.

Will announce a new target launch date once confirmed with the Range," SpaceX wrote on Twitter.

Dubbed B1051 by SpaceX, the booster was scheduled to make its fifth trip to space after launching two Starlink flights earlier this year as well as SpaceX's first Crew Dragon test flight and a trio of Earth-observing satellites for Canada in 2019. .

Along with a stack of 57 internet-beaming satellites, SpaceX is ferrying two small, Earth-observing satellites for BlackSky Global as part of a rideshare deal arranged bySpaceflight — a brokerage service that helps small satellites find rides to space. .

Depending on when SpaceX reschedules this launch, the company could have back-to-back launches next week as it  is already preparing for anotherlaunch.

In that mission, which is expected to launch for no earlier than Tuesday (July 14), SpaceX is preparing to launch the Anasis 2 communications satellite for South Korea. .

When it does get off the ground, the Starlink/BlackSky mission will mark the tenth Starlink mission to date for SpaceX as well as the eighth Starlink mission of 2020
