Snapshots from Atlas 5 launch

Lockheed Martin’s launch services team hopes to lure up to four commercial customers per year to fly on United Launch Alliance’s Atlas 5 booster as a stream of U.S. government missions is forecast to dry up starting in 2017, according to Lockheed Martin’s rocket sales chief.

Mission managers will be closely monitoring the weather for the first launch of astronauts aboard SpaceX’s Crew Dragon spacecraft, not just around the Kennedy Space Center, but along a corridor stretching thousands of miles across the Atlantic Ocean in case the crew capsule has to escape from its Falcon 9 rocket during the climb into orbit.

NASA has selected SpaceX to build a spacecraft to land the first astronauts on the moon since 1972, choosing Elon Musk’s space company over competing proposals from Jeff Bezos’s Blue Origin and the aerospace firm Dynetics, officials announced Friday.
