House committee supports

A House committee on Thursday approved an amendment to a bill that would clear NASA to launch an additional shuttle flight next summer to deliver critical supplies and equipment to the International Space Station.

The move came as the House Committee on Science and Technology was reviewing its version of NASA's $19 billion 2011 funding package. The Senate version of the appropriations legislation already included the additional flight. But major differences remain in other key areas, including how much money goes to support development of a new private-sector manned launch industry, the timetable for development of a NASA heavy-lift rocket for deep space exploration, and plans for a new government-designed manned spacecraft.

Even so, Science and Technology Committee Chairman Bart Gordon (D-Tenn.) said in a statement that the House legislation "sets a clear, sustainable, and executable path for NASA, especially in the area of human space flight."
The Obama administration earlier this year proposed canceling NASA's Constellation moon program, including the Ares I and Ares V rockets the agency had planned to build to replace the shuttle. The Orion crew capsule that would have been launched atop the Ares I rocket would be converted into a space station crew lifeboat.

At the same time, the president called for a transition to private-sector rockets and capsules to ferry astronauts to and from the space station, allowing NASA to focus on development of new heavy-lift rockets and capsules for eventual flights to nearby asteroids and, eventually, to Mars.

But the president's plan would defer work on a heavy lifter until 2015, delaying deep space missions beyond low-Earth orbit until the middle of the 2020s in favor of near-term development of advanced technologies.

Supporters of the administration's space policy applauded the shift to private-sector launch services, arguing that increased efficiencies and innovation would open up the high frontier to more extensive--and routine--use. Under the administration's proposed budget, NASA would spend $6 billion over the next five years to spur development of private-sector launch services.
