Snapshots from Atlas 5 launch

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander geared up for launch aboard a Soyuz spacecraft Saturday on a six-hour flight to the International Space Station.

A two-stage Northrop Grumman Antares rocket rolled out of its horizontal integration facility Monday for the mile-journey south to launch pad 0A at the Mid-Atlantic Regional Spaceport in Virginia, where liftoff on a space station resupply mission is scheduled for Wednesday.

SpaceX’s Crew Dragon spacecraft closed out a six-day test flight in low Earth orbit Friday with an on-target splashdown in the Atlantic Ocean, and officials hailed the ship’s performance before it flies with astronauts for the first time later this year.
