Live coverage: Mission control loses contact with Indian moon lander

On its second flight, SpaceX’s mammoth Falcon Heavy rocket hurled an Arabsat communications satellite the size of a school bus nearly one-quarter the way to the moon Thursday, days after NASA’s administrator identified the privately-developed rocket as a backup to the agency’s behind-schedule Space Launch System for sending astronauts back to the lunar surface.

An Orbital ATK Pegasus XL rocket carrying eight hurricane research satellites for NASA fired into orbit Thursday at 8:37 a.m. EST (1337 GMT) off the east coast of Florida.

SpaceX has moved up its next launch to Wednesday, one day earlier than previously planned. A Falcon 9 rocket will take off with the next 60 satellites for SpaceX’s Starlink broadband Internet network at 3:37 p.m. EDT (1937 GMT) Wednesday from pad 39A at NASA’s Kennedy Space Center in Florida. There’s a 90 percent chance of favorable weather for launch Wednesday.
