As many had expected, President Barack Obama has proposed terminating NASA's human space-flight program. Instead, the Administration's 2011 budget would provide money to the private sector for developing commercial spacecraft for space exploration. The decision will signal the end of the Constellation program, which was initiated by the previous Administration with the goal of returning American astronauts to the moon by 2020. The Administration appears to have paid heed to a report delivered by the Augustine commission last fall which said that NASA would not be able to continue with its human space-flight program without a boost of $3 billion a year. Under current budgetary constraints, that seemed like an impossible target. Stay tuned for more details.
