Photos: One more look at Orion’s launch

A decade in the making, the core stage for NASA’s first Space Launch System heavy-lift rocket rolled into the Vehicle Assembly Building at the Kennedy Space Center Thursday to join up with twin solid rocket boosters and an Orion capsule for an unpiloted test flight around the moon.

As a barebones Orion spacecraft awaits its first launch from Cape Canaveral, representatives of European governments agreed to fund the development of a power and propulsion element to take the crew capsule on voyages around the moon, to an asteroid, and eventually to Mars.

The White House’s $19.9 billion NASA budget outline released Monday would continue development of NASA’s heavy-lift Space Launch System rocket and Orion crew capsule and begin the deployment of a mini-space station around the moon as soon as 2022, but the proposal would cancel WFIRST, a flagship-class astronomy mission planned for launch in the mid-2020s.
