How NASA Plans to Send Humans Back to the Moon
The U.S. space agency is rigorously testing its Orion spacecraft in hopes of launching its first mission to the moon as early as 2019.
NASA has been subjecting its Orion space capsule to a battery of tests designed to tell whether the spacecraft is ready to ferry humans into orbit and beyond. So far, the capsule seems to be on track—in a series of maneuvers this week, a joint team of NASA and U.S. Navy specialists successfully recovered the spaceship from the sea off the coast of San Diego, simulating what would happen when a deep-space mission splashed back to Earth.
If all goes to plan, Orion will become NASA’s flagship technology for launching astronauts to orbit and even to deep space, including to the lunar surface and maybe Mars. Here’s what’s at stake with Orion, and what still needs to be done before it can blast off.
Wait, aren’t U.S. astronauts already getting into space?
Yes, but not on NASA spacecraft. The space shuttle program ended in 2011, and the remaining shuttles are now on display in museums around the country. Since then, American astronauts have had to hitch rides to the International Space Station on Russian rockets, and NASA has sent supplies to the ISS via SpaceX and Orbital ATK launches.
Until Orion becomes available, NASA astronauts have no other way to get to low-Earth orbit and beyond. Commercial space companies like SpaceX and Boeing are developing their own crew capsules capable of reaching the ISS. But when it comes to sending people to the moon or deeper into space, it’s not clear yet who will be first to the launch pad…
