Shooting for the Moon, Once Again
# Thirty-four years after the end of the Apollo program, the U.S. and several other nations are gearing up for new exploration missions.

HOUSTON — Behind 18 inches of concrete in stainless steel cabinets flushed with pure nitrogen rests a material rarer than gold, more valuable than diamonds.

Not even NASA curator Gary Lofgren knows both combinations to the Johnson Space Center's vault that contains 600 pounds of lunar rocks and soil.

Of late, Lofgren has noticed something unusual — there's been a run on moon dirt. Gram by precious gram, he's been doling out samples to researchers around the world eager to study the desolate orb again.

Thirty-four years after the last Apollo astronaut walked on the lunar surface, a new space race is underway.

It will be a long race, with humans unlikely to set foot on the moon again in the next 10 to 15 years. But countries are gearing up to take their first steps.

India's 20,000 space workers are readying a lunar orbital mission set for 2007. Japan plans to send a robotic rover to the lifeless rock by 2013, and the European Space Agency has a probe, SMART-1, orbiting the moon.

Although many countries are talking about sending people to the moon, only two, the United States and China, have set dates for manned lunar landings. NASA says its next manned mission will be as early as 2018; China says it wants to land "taikonauts" — as Chinese astronauts are called — as early as 2017.

"There is a lunar armada" on the way back to the moon, said James B. Garvin, head of NASA's Lunar Reconnaissance Orbiter project, scheduled to lift off in 2008.

It's an unlikely renaissance of lunar exploration after decades of sending robots to distant planets while human explorers busied themselves building a space station in low-Earth orbit.

Each country is going for its own reasons — some commercial, some strategic, some for national pride. But if the plans come to fruition, the moon could become a busy extraterrestrial outpost for scientists, engineers and possibly ordinary citizens in the coming decades. It would also serve as a vital way station for man's long-dreamed-of trip to Mars.

Leading the way is the only country that has set foot there before, the United States.

Two years from now, NASA will begin launching probes to search for landing sites and potential water sources at the moon's south pole. Work is underway on new generation lunar projects, including a souped-up rover and a $38-million project to extract breathable oxygen from moon dust.

All this has gotten NASA's workforce, which has been demoralized by the frustrations and tragedies of the ill-fated space shuttle program, fired up in ways it hasn't been since the 1960s.

But there are plenty of doubters.

Why bother with the moon? The U.S. has been there. Six times. On each occasion, explorers have found the same barren world — a place of "magnificent desolation," in the words of Apollo astronaut Buzz Aldrin.

Visionaries such as Gregg Maryniak, director of the James S. McDonnell Planetarium in St. Louis, have little patience with those who say, "been there, done that" about the moon.

"That's like saying you've seen New York when you changed planes at JFK."

Lost Landscape

Bouncing along a patch of Texas flatland at the Johnson Space Center, NASA engineer Joe Kosmo steered his pickup truck onto a field covered with tangled tufts of grass.

Kosmo hopped out and began tramping into the weeds.
