NASA to test-fly Orion spacecraft

MOUNTAIN VIEW, Calif. -- NASA officials said Wednesday that the space agency is on track to launch its first flight test in September 2008 of the Orion spacecraft, the successor to the space shuttle that's expected to take astronauts back to the moon by 2020.

NASA is halfway through the key portion of its contract with Lockheed Martin, which is building the spacecraft, before it begins tests at the White Sands Missile Range next fall, according to Skip Hatfield, Orion manager at NASA's Johnson Space Center.

"We're making great progress," Hatfield said during a press conference here at NASA Ames Research Center. The conference was organized to provide an update on the progress of NASA's development of the Orion spacecraft, as part of the Constellation Program.

The progress report comes a week after NASA said that it's investigating sabotage of a non-critical computer due to be flown to the International Space Station aboard the space shuttle, which was cleared to lift off on Tuesday. NASA also revealed last week that it allowed inebriated astronauts to fly on at least two occasions despite their posing a flight risk.

Much of NASA's future focus these days seems to be on the Constellation Program, whether on developing the crew vehicle or testing robotic rovers that can explore uncharted craters on the moon. Once the space shuttle Endeavour is retired in 2010, Orion is slated to be the primary craft for human space exploration, taking astronauts to the ISS by 2015 and onto the moon by no later than 2020. NASA hopes to use the vehicle for other deep space missions onto Mars or an asteroid.

Hatfield said Orion will resemble the Apollo spacecraft that took three astronauts to the moon and back in 1969. Yet Orion will be much larger and capable of carrying six people in its crew capsule to the space station (four to the moon). Orion will be 16.5 feet in diameter and have a mass of about 25 tons. Inside, it will have more than two and a half times the volume of an Apollo capsule. Also, where Apollo's power system used fuel cells, Orion will use solar arrays.
