Despite uproar, Obama holds firm on NASA space exploration plans
Lawmakers and former astronauts have lambasted President Obama for scrapping a moon mission. Thursday, Obama will defend his vision for NASA space exploration through human spaceflight.

The goal is to give the advocate-in-chief an opportunity to make his case for proposals that represent the most radical overhaul of the National Aeronautics and Space Administration's human spaceflight effort in the agency's storied 52-year history.
In a preview of the president's key bullet points on how humans will fit into NASA space exploration, administration officials yesterday offered additional details about the approach.
- Convert the capsule initially designed to carry humans and cargo to the International Space Station under the Bush administration's Constellation program to an emergency return "lifeboat" vehicle for the space station.
- Choose a design for a new heavy-lift rocket that could take astronauts and cargo beyond Earth orbit by 2015 – two years earlier than would have happened under the Constellation program.
- Pursue "stepping stone destinations" such as asteroids or orbiting Mars during the decade of the 2020s, all in anticipation of eventually landing humans on Mars.
But if advocates for the Bush-era Constellation program – and its deadline for putting Americans back on the moon – were hoping to see the president outline significant changes to his blueprint for NASA after two months of withering criticism, they are likely to be disappointed.
"It's not a radical departure" from the plan the administration outlined in February, when it released its fiscal 2011 budget proposals, says James Lewis, a senior fellow specializing in space and technology policy at the Center for Strategic and International Studies in Washington.
The president's plan
Under the president's plan, the Constellation program – aimed at returning US astronauts to the moon by 2020, but which many analysts say was underfunded to achieve that goal – would be virtually eliminated.
The shuttle program would fly out its final three mission by early 2011. US participation in the International Space Station would extend to at least 2020. And the task of transporting cargo and eventually astronauts to the International Space Station in low-Earth orbit would fall to privately financed and operated rocket companies.
