Video: Orion countdown status briefing

The next time astronauts land on the moon, they will ride to the lunar surface in a spacecraft that looks a lot different than the Apollo-era landing module last used in 1972. Lander concepts proposed by SpaceX, Blue Origin and Dynetics — which won a combined $967 million in NASA funding Thursday — take wildly different approaches to carrying crews to the moon.

NASA and industry teams at Cape Canaveral launched an Orion capsule on a three-minute atmospheric test flight Tuesday to prove the spaceship’s ability to escape from an exploding rocket during launch, demonstrating a key safety feature before astronauts ride the vehicle into deep space. Liftoff occurred at 7 a.m. EDT (1100 GMT).

Lessons learned during preparations leading up to the first orbital test flight of NASA’s Orion spacecraft in December have prompted engineers to recommend changing the design of the crew capsule’s heat shield for future missions to the moon, Mars, or an asteroid, according to Lockheed Martin officials.
