NASA will stay on track to return humans to the Moon by 2020, according to an overview of President Obama鈥檚 2010 budget request released on Thursday.
Recently, various groups 鈥� including Apollo astronaut Buzz Aldrin and the space advocacy group the Planetary Society 鈥� have called for NASA to send astronauts to new destinations, such as asteroids.
But the budget request backs a plan developed under the Bush administration to retire the space shuttle by 2010 and develop a system to return humans to the Moon by 2020.

However, the does not specify whether the Moon return will be accomplished by NASA鈥檚 Constellation programme, which aims to build a crew capsule called Orion and rockets called Ares to replace the shuttle.
Obama鈥檚 transition team was reported to have raised questions about the programme鈥檚 Ares rockets, which have been plagued by design concerns that include excess vibrations.
Some argue that existing rockets, such as the Atlas V or Delta IV currently used to loft spacecraft, would be better alternatives, while others back a new design.
鈥楶roceed as you were鈥�
NASA鈥檚 former chief, Mike Griffin, was a staunch supporter of the Constellation programme, but he resigned in January and his successor has not yet been named.
鈥淭he budget doesn鈥檛 say a whole lot about any specific system,鈥� says John Logsdon, a space policy analyst at the National Air and Space Museum in Washington, DC. 鈥淚 wouldn鈥檛 interpret the absence of the words 鈥楥onstellation鈥�, 鈥楢res鈥�, and 鈥極rion鈥� one way or another. That鈥檚 really up to the the new management team, when it gets there.鈥�
Indeed, NASA is planning to stay the course 鈥� at least for now. 鈥淭he direction we have at the current time is, 鈥楶roceed as you were,'鈥� says agency spokesperson Stephanie Schierholz.
Under the proposed budget, the agency would receive $18.7 billion in 2010. Combined with $1 billion in funding provided in an economic stimulus package signed into law last week, NASA would get $2.4 billion more than it did in 2008.

鈥淚t鈥檚 a nice number,鈥� Logsdon told New 杏吧原创. 鈥淏etween the proposed increase and the stimulus package, NASA鈥檚 $2.4 billion [would leave it] better off than it was last year.鈥�
The budget would also likely be a boost over 2009 funding levels. The agency鈥檚 2009 budget has not yet been settled. NASA has been operating at 2008 funding levels under a continuing resolution since October 2008.
But on Wednesday, the US House of Representatives passed an omnibus bill to fund NASA for 2009. It calls for a $360 million increase in the agency鈥檚 human exploration budget, which includes $2.9 billion for the Constellation programme. NASA鈥檚 science budget would decline $200 million from 2008 levels. The US Senate is now considering the bill.
Climate change research and monitoring tops the list of funding highlights in the overview of NASA鈥檚 budget request, but the budget for specific agency programmes is not included. A detailed budget request is not expected before April.
