What is the Orion space program and what are its goals?
Orion is a program that aims at sending astronauts into deep space.
The spacecraft Orion is a "Multi-Purpose Crew Vehicle" (MPCV). It can carry a crew of four in or above 'low Earth orbit' (anywhere from 160km to 2000km above Earth's surface). NASA plans to send Orion to explore nearby asteroids and Mars as well as providing transport to and from the ISS. You can read more about Orion here.
