Orion Spacecraft and ISS: NASA's Path to Human Space Exploration
Human space exploration goals for the 21st Century include destinations both in low-Earth orbit to the International Space Station and deep space missions to an asteroid and even to Mars. Different exploration destinations require different systems. NASA's journey to Mars has taken a critical step forward with the successful test launch of the Orion spacecraft. Meanwhile, NASA's Commercial Crew Program is spearheading the development of two commercially owned and operated space transportation systems that will give astronauts safe, reliable, and cost-effective access to and from the International Space Station, where cutting edge research and technology developments are increasing our knowledge about what it takes to live and work for long periods of time in space.
