According to Science, by the end of this month NASA is expected to come up with a set of “recommendations” for spacecraft and astronauts visiting the “U.S. government property on the moon.” Of course, these recommendations will not be legally binding as the 1967 Outer Space Treaty makes it clear that the lunar surface has no owner.

As dozens of private teams race to return to the moon as soon as next year, spurred on by $30 million in prize money from Google and the X Prize Foundation, NASA is wrestling with how to safeguard the historic and scientific value of more than three dozen sites containing remnants of America's golden era of space exploration, including the spot where Neil Armstrong and Edwin "Buzz" Aldrin Jr. left the first footprints on the lunar surface. Later this month, the agency plans to issue what it calls "recommendations" for spacecraft, or future astronauts, visiting U.S. government property on the moon.
