What are the goals of the Orion space program?
To carry people beyond low Earth orbit. It's the vehicle that is intended to carry astronauts to Mars.
In terms of manned space flight, humanity has done little more than escape Earth's gravity well. Currently people orbit the Earth in the International Space Station and by far the furthest any human has ever traveled has been to the Moon and back.
Orion is the next generation of manned space vehicles and will allow humans to fly to asteroids and even to Mars.
