Celestis provided its first Luna Service mission by helping friends of noted planetary geologist Dr. Eugene M. Shoemaker include a symbolic portion of Dr. Shoemaker’s remains on the NASA Lunar Prospector mission launched January 6, 1998.

The spacecraft impacted the lunar surface inside a permanently shadowed crater near the south lunar pole, creating a permanent monument to Dr. Shoemaker. Impact occurred at 4:52 a.m. CDT (9:52 a.m. GMT), July 31, 1999.

Dr. Eugene M. Shoemaker, a pioneer in the exploration of the Solar System, had longed to go to the Moon as an Apollo astronaut and study its geology firsthand. A medical condition diagnosed in the early 1960s prevented him from doing so. Dr. Shoemaker went on to help select and train Apollo astronauts in lunar geology and impact cratering. His achievements in these areas earned him the United States’ highest scientific honor, the National Medal of Science in 1992. He became world-renowned when he, his wife Carolyn, and astronomer David Levy discovered Comet Shoemaker-Levy 9, which impacted the planet Jupiter in July 1994.

Lunar Prospector was one of the most productive, least expensive space missions. Part of NASA’s Discovery Program, Lunar Prospector served as a follow-on to the successful Clementine mission of 1994. In 1994, the Clementine spacecraft orbiting the Moon made observations that indicated the presence of water ice on the lunar surface. On March 5, 1998, it was announced that Lunar Prospector had also found evidence suggesting the presence of water ice at both lunar poles.

The presence of water ice on the Moon would facilitate future attempts at lunar colonization. How fitting that Dr. Eugene Shoemaker participated in one last experiment — an experiment that could benefit our future in space.
