Live coverage: SpaceX supply ship returns to Earth

Something went wrong with a Russian Progress cargo spacecraft moments before it deployed into orbit Tuesday on the way to the International Space Station, and investigators are analyzing whether the stricken supply ship may have lost control after a botched separation from its Soyuz rocket booster.

SpaceX’s next Falcon 9 rocket is being readied for liftoff Aug. 14 on a space station resupply run. The two-stage rocket completed a hold-down engine firing Thursday at launch pad 39A at NASA’s Kennedy Space Center in Florida.

The flight will include 23 Starlink V2 Mini satellites, of which 13 have Direct to Cell capabilities. Liftoff from pad 40 at Cape Canaveral Space Force Station is set for 10:19 a.m. EST (1519 UTC).
