Different destinations call for different vehicles and approaches on Earth – just ask anyone who has taken an RV on a family vacation! NASA is applying that philosophy to space exploration with Commercial Crew and the Orion/Space Launch System.
The two spacecraft under development by Commercial Crew providers Boeing and SpaceX are destined for the International Space Station, orbiting more than 250 miles above Earth. Astronauts will fly inside the Boeing CST-100 and SpaceX Crew Dragon spacecraft to reach the station where they will conduct research off the Earth, for the Earth. Both the CST-100 and Crew Dragon will fly into space aboard rockets certified to safely carry astronauts to low-Earth orbit.
NASA’s Orion spacecraft is built to be launched aboard the massive Space Launch System, the first rocket since the Saturn V designed to send astronauts beyond the bounds of Earth orbit and into deep space. Astronauts inside Orion will conduct exploration missions to near-Earth asteroids and in the proving ground around the moon before making the journey to Mars in the 2030s. It’s a strategy involving all of the space agency’s human spaceflight knowledge and hard-won experience.
