Photos: Atlas 5 rolls out for Friday launch to GPS constellation

This collection of photographs shows the Air Force’s Global Positioning System 2F-10 navigation satellite being encapsulated in the Atlas 5 nose cone and hoisted atop the rocket for launch July 15.

The U.S. Air Force has committed $109 million in funding to advance development of new rockets designed by United Launch Alliance, Blue Origin and Northrop Grumman, leaving out SpaceX in a government investment round that will lead to the military’s selection of two long-term launch providers in late 2019 or 2020.

NASA safety advisors on Thursday lauded hardware milestones on Boeing and SpaceX commercial crew capsules, but said multiple technical issues, including problems with parachutes, must be resolved before the human-rated ships are ready to carry astronauts, adding that both companies continue to pursue schedules that appear to be unachievable.
