Shuttle Atlantis unwrapped ahead of public debut

SpaceX launched 60 more Starlink satellites Wednesday into a sunny sky over Florida’s Space Coast, adding more capacity and coverage to the company’s commercial broadband network while setting new records for the pace it is reusing Falcon 9 rocket boosters.

The launch of NASA’s Mars 2020 rover is less than a year away, and the steady pace of work inside the craft’s pristine assembly hall in California is keeping the mission on schedule for liftoff from Cape Canaveral next July, despite growing costs, according to mission managers.

The towering structure to be used for liftoffs of NASA’s Space Launch System rolled from a construction site to launch pad 39B at the Kennedy Space Center in Florida this week, arriving at the seaside complex Friday for a week of fit checks.
