NASA’s deep space missions may get new jolt of fuel

May 8, 2009 at 12:53 pm

The Energy Department has requested $30 million to relaunch a program to make radioactive plutonium-238, the supply of which is running low.

The Energy Department plans to restart its program of making radioactive fuel for NASA’s deep space missions, the agency announced Thursday, a decision that came only hours after the National Research Council warned that the nation was fast running out of the fuel.

Jen Stutsman, a spokeswoman for the department, said the agency had requested $30 million in its fiscal 2010 budget proposal to restart the fuel-making process. In its budget statement, the agency said it had “a long and successful history” of supporting NASA’s needs. It said it welcomed the National Research Council findings.

In a 74-page report titled “Radioisotope Power Systems: An Imperative for Maintaining U.S. Leadership in Space Exploration,” the council pointed out that American leadership in space has depended in part on the ability to power spacecraft on deep space missions, in which the sun’s rays are too weak for generating solar power.

For such research, which includes the New Horizons mission now heading for Pluto and the Cassini mission now orbiting Saturn, the electricity that powers onboard instruments comes from devices called radioisotope power generators. The RPGs make electricity with the heat from the radioactive decay of small amounts of plutonium-238 carried on board. 

According to Ralph McNutt, a space scientist at Johns Hopkins University and co-chairman of the committee that produced the report, the United States stopped making Pu-238 about 20 years ago, with the end of the Cold War. Although Pu-238 is not weapons-grade material, it is a byproduct of making the more dangerous Pu-239, he said.

NASA uses about 11 pounds of Pu-238 each year. In recent years, it has purchased some of the material from Russia, but unless it makes new Pu-238, McNutt said, NASA will run out by the end of the next decade. That will leave enough fuel to power only the upcoming Mars Science Laboratory and outer planet missions, he said. 

The Mars Science Lab is a rover about the size of a minivan that will be able to roll over large rocks, which have deterred the smaller rovers previously sent to Mars. An outer planet mission, set for 2020, which will visit Jupiter and its moons Europa and Ganymede, is still being designed.

Mars Institute to drive HUMMER-based rover through Northwest Passage

It might seem a bit paradoxical to drive a HUMMER for 1,200 miles across the thin ice of the Northwest Passage with the goal of investigating climate change in the arctic circle, but that’s exactly what a crew from the Mars Institute is planning to do. The team will be charting the thickness of the ice as it moves at about 12 miles per hour over the surface, but the information gathered during the trek will really just be a bonus. The team’s first priority will be to see how the HUMMER-based rover fares in these harsh conditions. At some point, the Mars Institute hopes that this data will prove useful in helping NASA design human-toting vehicles that will be able to traverse the surface of Mars.
The Scientific American reports :  The trip using a modified armored Humvee vehicle will provide comprehensive data about the thickness of winter ice in the waterway through Canada’s high Arctic, said Pascal Lee, chairman of Mars Institute and leader of the expedition.  (Above Image on Right:  An ice-free Northwest Passage seen in this handout satellite photo from NASA taken in Sept. 2007. Photograph courtesy: Vancouver Sun via Terra Satellite/NASA, Reuters)

The scientists also hope to learn more about what happens to the microbes left behind by humans as they explore remote areas, amid concerns from some scientists about the detrimental impact of such journeys in space.

Satellite Collision May Have Endangered All Future Space Launches

Remember when those two satellites collidedthe other day? Seems that they’ll be thespace junk gift that keeps on giving, as their 800-km debris orbiting field could hamper allfuture space launches.

“Future launches will have to be adjusted with regard to the fact that the debris [from the collision] has spread over an 800-km area and will gather at a common orbit in 5-6 years,” said Alexander Stepanov, director of the Pulkovo Observatory in St. Petersburg.
