Q&A with Mike Laidley, vice president of Orbital ATK’s Next Generation Launch program (members only)

A German-built satellite designed to relay data between other orbiting spacecraft and ground stations using laser beams is set for launch in tandem with an Intelsat communications craft Tuesday from Kourou, French Guiana, aboard an Ariane 5 rocket.

Rocket Lab’s first mission for the National Reconnaissance Office, which owns the U.S. government’s fleet of intelligence-gathering satellites, is scheduled to launch from New Zealand as soon as Jan. 30 (U.S. time), officials announced Monday.

When SpaceX’s Falcon Heavy rocket finally takes off for the first time, a debut now scheduled this fall, there’s a good chance the commercial heavy-lifter will falter short of reaching orbit, company founder and chief designer Elon Musk said last week.
