NASA tests new rocket booster

NASA has tested a motor for a powerful rocket booster for it's new deep space rocket, the Space Launch System (SLS).

The two-minute test of the booster's motor was meant to give NASA more information, that should help them when they blast, off in 2018 with a deep-space Orion capsule.

The SLS and the Orion spacecraft are designed to fly astronauts to the moon, asteroids and eventually Mars.
