Live coverage: Proton launch runs into trouble

Packed with nearly 3 tons of rocket fuel, water, oxygen and crew provisions, the Russian Progress MS-12 supply ship and its Soyuz booster arrived at a launch pad Sunday at the Baikonur Cosmodrome in Kazakhstan, moving a step closer to liftoff Wednesday on a fast-track three-hour flight to the International Space Station.

SpaceX plans to deploy the next group of Starlink internet relay spacecraft Sunday with a liftoff on top of a Falcon 9 rocket from NASA’s Kennedy Space Center, the company’s fourth satellite launch of the month.

For the third time in 10 days, SpaceX is readying a Falcon 9 rocket for launch Sunday from Florida’s Space Coast with another 60 Starlink internet satellites. This time, SpaceX aims to extend the record for reusing a Falcon 9 booster to nine flights.
