Even as the National Aeronautics and Space Administration is set to receive billions of dollars in additional funding for technology in the latest White House budget, the agency has yet to chart a detailed course for future manned space flight once the space shuttle is retired in 2011.


That could erode congressional and public support for NASA, according to some industry officials and lawmakers.


NASA Administrator Charles Bolden predicted that the proposed $19 billion fiscal-2011 budget, an increase of 2% from the previous year, would be "good for NASA." He added that a plan to rely on private companies to ferry astronauts to the International Space Station would be "great for the American work force."



But the budget, which created an element of uncertainty about NASA's priorities, is likely to further stoke fierce congressional opposition.


Drastic shifts envisioned in NASA's fiscal-2011 budget include killing Constellation, the current program intended to send astronauts back to the moon, and replacing it with initiatives to stimulate various commercial space projects and create a new generation of heavy-lift rockets able to penetrate deeper into space. The spending package also seeks greater international cooperation, even on the highest-priority manned projects, along with ambitious new efforts to develop in-orbit construction and refueling capabilities.

根据NASA 2011财年预算的构想,该机构工作重点的一个巨大转变将是取消派宇航员重返月球的“星际计划”,取代它的将是以促进各种各样商业太空项目以及开发新一代大推力火箭为目的的一系列计划。这些火箭将能把航天器送入更深的太空。NASA新的支出计划还将寻求扩大国际合作,具体领域甚至包括被视为NASA最优先工作的载人航天项目,以及旨在开发在轨建造和燃料补充能力的新项目。

Despite the request for an increase in funding, the budget package doesn't lay out detailed timetables or destinations for future manned exploration. Instead, it seeks to save money in the short term by turning over to private enterprise the job of transporting astronauts to the International Space Station.


When it comes to substantially longer, more complex missions envisioned for coming decades, the spending plan simply puts in place technology-development efforts NASA would nurture until those decisions are made.


Lori Garver, the agency's No. 2 official, told reporters Monday that the aim is to "unleash the economic potential of space" by letting private enterprise bid on contracts intended to "take us further and faster and more affordably" to landings on the moon, asteroids and eventually Mars. A joint NASA-White House statement released along with the budget blueprint suggests that unmanned missions will grow in prominence for at least the next decade, though it stopped short of detailing how.
