Photos: Atlas 5 rolls out for launch

The 377th Delta rocket begins its journey to space carrying a military communications satellite funded by Canada, Denmark, the Netherlands, Luxembourg and New Zealand in a deal that gives the allies access to the U.S. military’s worldwide Wideband Global SATCOM system.

NASA has released new target dates for test flights of commercial crew capsules in development by SpaceX and Boeing, with unpiloted demo missions by SpaceX’s Crew Dragon and Boeing’s CST-100 Starliner spaceships now scheduled for January and March, followed by crewed orbital missions in mid-2019.

This photo gallery shows the U.S. Navy’s third Mobile User Objective System (MUOS) satellite being encapsulated in the rocket’s nose cone and being lifted atop the Atlas-Centaur vehicle. Liftoff is planned for Jan. 20.
