Live coverage: Falcon 9 launches with Thai satellite and first stage lands at sea

Riding on a mobile launch platform, an Ariane 5 rocket made the 1.7-mile trip from its final assembly building to the ELA-3 launch zone in Kourou, French Guiana, on Monday morning, one day before its blastoff on a commercial mission with Australian and Indian communications satellites.

SpaceX’s Falcon 9 rocket closed out a busy 2017 Cape Canaveral launch schedule on Dec. 15 with a successful liftoff on a space station resupply mission. The Falcon 9’s first stage booster, making its second launch, returned to Florida’s Space Coast for an on-target landing.

One of four landing legs mounted to the base of SpaceX’s Falcon 9 booster failed to engage on the rocket’s final descent to a barge in the Pacific Ocean on Sunday, leaving wreckage scattered on the football field-sized deck of the landing ship after an otherwise successful launch with an ocean research satellite.
