Live coverage: India’s Chandrayaan 2 moon mission blasts off

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 kicked off Memorial Day weekend with an overnight launch Saturday from Cape Canaveral, boosting a nearly five-ton communications satellite into orbit for Arabsat, a multinational consortium providing TV and video broadcast services across the Middle East.

A prototype for China’s next-generation human-rated spacecraft — flying on a test flight without astronauts — is scheduled to ride a new version of the country’s heavy-lift Long March 5 rocket into orbit this week.
