NASA's Robotic Moon Mission Spins Wheels

CAPE CANAVERAL -- NASA's plan to send robotic scouts to the moon in advance of astronauts is starting to take shape, but politics and the presidential election are stalling progress.

Congress appears poised to ax most if not all start-up money for an initial lunar mapping mission in 2008 but won't finalize the agency's budget before the election Tuesday.

Outside analysts say NASA is hesitant to draft detailed plans for follow-on flights -- missions key to President Bush's plan to return astronauts to the moon -- until the election is over.

"They are not going to go forward with the vision until they see how the election is going to turn out, and that's true of Congress also," said Paul Spudis, a planetary geologist at Johns Hopkins University who served on the President's Commission on Moon, Mars and Beyond.

"Seriously, their people are running in place and they want to see what's going to happen," Spudis said. "My sense is that we won't actually get moving out on this -- on the detailed architecture and strategy studies -- until that is resolved."

Bush in January outlined a plan to complete the International Space Station and retire NASA's shuttle fleet by 2010. Robotic spacecraft would be sent to the moon to pave the way for astronauts, who would return to the lunar surface between 2015 and 2020.

The robotic craft also would help determine how to protect human explorers from deadly cosmic and solar radiation they would be exposed to outside Earth's magnetic field.

"When we go back to the moon with humans, we want to be able to do it in the right way," said Richard Vondrak, director of the lunar robotic explorer program at NASA Headquarters in Washington.

"And the robotic missions will provide information and test beds that will prepare us for the return to the moon in the best possible way."

NASA's Lunar Prospector and the Pentagon's Clementine spacecraft yielded evidence in the 1990s of abundant stores of water ice trapped beneath the surface at the poles.

NASA gathered instrument proposals for the lunar orbiter from aerospace companies, universities and research labs in September. But a decision on which instruments would fly won't be made before late November.

NASA's plans for a second robotic spacecraft, which would launch in 2009, are much less mature. Vondrak said the spacecraft likely would be a lander with instruments that would verify the existence of water ice and measure radiation.

The aim: develop and deliver the systems that would enable astronauts to use the moon's natural resources to survive on the lunar surface, significantly reducing the need to launch costly resupply missions from Earth.

"In broad terms, what you want to do is to conduct a series of robotic missions that will allow you to design the equipment you need to live on the moon," Spudis said. "And then you launch the equipment and assets that you'll need when you get there."

The House Appropriations Committee cut NASA's entire $70 million request for start-up money in 2005. In the Senate, the appropriations committee slashed all but $20 million. A House-Senate conference committee won't take up the issue until after the election.

"Going to the moon is an important first step in that journey that leads us to further destinations," Vondrak said. "We want to use it as a way to prepare for human exploration beyond the moon."
