The most controversial part of the president’s policy is the cancellation of the Constellation program, which was aimed at developing a new generation of Ares rockets and Orion spacecraft to send astronauts into Earth orbit and beyond.

The idea was that such spacecraft would replace NASA’s space shuttle fleet, which is to be retired by the end of this year. But acting on the advice of an independent panel, the Obama administration determined that the Constellation program could not fulfill NASA’s goals on the required timetable. NASA’s budget proposal, released in February, puts the return to the moon on indefinite hold and instead focuses of developing technologies for future exploration.
