The second race to the moon has begun—and this time there will be a big cash payout for the winner. Four decades after Neil Armstrong took his giant leap for mankind, the Google-sponsored Lunar X Prize is offering $20 million to any private team that puts a robotic rover on the moon, plus $5 million in bonus prizes for completing such tasks as photographing one of the numerous man-made artifacts that remain there—for instance, the Apollo 11 lunar module descent stage that Armstrong and Buzz Aldrin left behind in 1969.
One goal of the Lunar X Prize is to rekindle excitement in space exploration by beaming pictures of historic lunar locations to Web sites or even cellphones. But dispatching robots to snoop around the moon also poses a risk to some of the most precious archaeological sites of all time. What if a rover reached Tranquility Base, where Armstrong landed, and drove over footprints, which are still intact and represent humanity's first expedition to a celestial body? William Pomerantz, the director of space projects for the X Prize Foundation, acknowledges that possibility. "There's always a tradeoff between wanting to protect the history that's already there and wanting to visit the history," he says.
The competition brings into focus a potential problem that worries a growing circle of archaeologists and space historians: the careless destruction of invaluable lunar artifacts. At Charles Sturt University in Australia, Dirk H.R. Spennemann—who specializes in the preservation of technological artifacts—says Tranquility Base symbolizes an achievement greater than the building of the pyramids or the first Atlantic crossing. And because the moon has no atmosphere, wind, water or known microbes to cause erosion or decay, every piece of gear and every footprint remain preserved in the lunar dust. Spennemann advocates keeping all six Apollo sites off-limits until technology enables space-faring archaeologists to hover above them, Jetsons-like. "We only have one shot at protecting this," he insists. "If we screw it up, it's gone for good. We can't undo it."
The initial response to the Lunar X Prize initiative—which had ten registered teams at the end of April—suggests the moon's remoteness won't discourage unofficial visitors for long. History teaches a similar lesson. When the Titanic sank in 1912, few imagined that it would become an attraction. But not long after Robert Ballard discovered the wreckage in 13,000 feet of water in the North Atlantic in 1985, treasure hunters in submarines looted the doomed vessel of jewelry and dinnerware.
Crafting an agreement that bars exploration of lunar sites in the coming age of space tourism may be difficult. To be sure, nations retain ownership of spacecraft and artifacts they leave on the moon, though it (and the planets) are common property, according to international treaties. In practical terms, that means no nation has jurisdiction over the lunar soil, upon which artifacts and precious footprints rest. "It would be our strong preference that those items remain undisturbed unless and until NASA establishes a policy for their disposition," says Allan Needell, curator of the Smithsonian National Air and Space Museum's Apollo collection. The "preservation of the historical integrity of the objects and the landing sites" would be a primary goal, he adds.
How much stuff have people left on the moon? Professors and students from New Mexico State University (NMSU) cataloged equipment left behind at Tranquility Base and identified more than 100 items and in situ features from Apollo 11 alone, including Buzz Aldrin's boots, Armstrong's famous footprint and a laser ranging retroreflector, which, for the first time, measured the precise distance between the moon and Earth. Much of the equipment was discarded by Armstrong and Aldrin just prior to lifting off to rendezvous with the orbital craft that would take them home; they needed to lighten the lunar module ascent stage, which they'd burdened with 40 pounds of lunar rocks and soil.
The New Mexico researchers had hoped that their inventory would help them gain protection for Tranquility Base as a National Historic Landmark. But the National Park Service, which oversees the program, rejected the proposal, saying the agency doesn't "have sufficient jurisdiction over the land mass of the Moon." Moreover, a NASA lawyer advised that merely designating a lunar site a landmark "is likely to be perceived by the international community as a claim over the Moon"—a land grab that would place the United States in violation of the 1967 Outer Space Treaty. So Beth Laura O'Leary, an anthropologist who led the NMSU project, added the historic lunar site to an official list of archaeological sites maintained by the state of New Mexico. It's a largely symbolic gesture, but it does mean at least one governmental body recognizes Tranquility Base as a heritage site. "You don't want people putting pieces of Apollo on eBay any more than you want them chiseling away at the Parthenon," O'Leary says.
Of course, NASA itself has done some extraterrestrial salvaging. In 1969, in arguably the first archaeological expedition conducted on another world, Apollo 12 astronauts Alan Bean and Pete Conrad visited the robotic Surveyor 3 spacecraft, which had landed two years earlier. They inspected the landing site and removed the spacecraft's television camera, a piece of tubing and the remote sampling arm. The parts were returned to Earth so researchers could assess the lunar environment's effects on equipment.
On July 20, 2006, Dr. O'Leary's efforts resulted in designation of the Apollo 11 Tranquility Base archeological site on the moon as LA 2,000,000 in the State of New Mexico's Archaeological Records Management Section (ARMS)database. The New Mexico Museum of Space History in Alamogordo, NM, serves as the host for the LA 2,000,000 on Earth. The location of the marker at the museum is forever linked to the lunar landing site.

Ref to returning to historical sites--I fully agree with the argument that sites on the moon should be off limits to X Prize or other related ventures. These sites must be documented by Lunar archaeologists and space historians. It was the humble and fuzzy images as transmitted to Earth that help spark the imaginations of many people around the world as well as those who continued into scientic studies. I am one of those. I have a photograph of the moon and the region where Armstrong landed at Tranquility Base. The photo was taken when the astronauts were on the Moon. While you cannot see them or the lunar lander--it always reminds me of the great event. We must not make the mistakes we have made here, just for commercial purposes.

I really doubt that Armstrong's first few footprints are there. Climbing in and out of the lander would have mucked them up as well as the engine blast when the lander lifted off to come home.
