Eugene Shoemaker Is Still the Only Man Buried on the Moon

For now, anyway.

Enough human beings have walked on the moon at this point that it’s almost the “visiting the Empire State Building” of space exploration. But for as many living people who have taken a walk on that far away rock, there is only one dead man who’s ever been put to rest there.

To date, the late scientist Eugene Shoemaker is still the only person whose remains have been sent to the moon. Even casual stargazers are likely to recognize Shoemaker’s name from the famed Shoemaker-Levy comet (which had broken into fragments) that impacted Jupiter in 1994. The comet, which Shoemaker discovered with his wife Carolyn alongside David Levy, was remarkable because it marked the first time humans were able to witness a first-hand planetary collision. The crash got so much press attention that a small town in Wyoming set up an intergalactic landing strip to welcome any potential refugees from Jupiter, and Shoemaker became a household name.

Shoemaker enjoyed a celebrated career combining his main discipline of geology with more astronomical applications, helping to create the field of planetary science. He studied a number of craters here on Earth, and in the early 1960s, he founded the Astrogeology Research Program within the United States Geological Survey. Shoemaker used his knowledge to train a number of Apollo mission astronauts about what they could expect to find on the surface of the moon, in terms of terrain.

His fascinating life came to an abrupt end on July 18, 1997, when he died in a car crash while exploring a meteor crater in Australia. But even in death, as it turned out, his journey was far from over.

Enter Celestis, the only company that has ever successfully conducted memorial spaceflights. “Our first launch was in April of 1997 out of the Canary Islands,” says Charles Chafer, CEO and Co-Founder of Celestis. “We flew 24 people on what we call the ‘Founder’s Flight.’ Some well-known folks like Timothy Leary and Gene Roddenberry. Also some space-geek folks, like Gerard K. O’Neill, but mostly normal folks.”

Celestis works by securing any extra room on space launches that are already occurring, and sending the ashes up as a secondary payload. “I think the term of art these days is ‘rideshare,’” says Chafer. So, if a rocket is set to head into space, and there is a little wiggle room in terms of space and weight, Celestis tries to fill that with remains. Generally, whatever piece of equipment the memorial payload is attached to ends up in Earth’s orbit. “Our payload is always attached to something, whether that’s a spacecraft or a spent rocket stage. Things that are small enough that at the end of their orbital lifetime, they burn up completely on reentry,” says Chafer. “Sort of an ashes-to-ashes moment.”

But with Shoemaker it was a little different. A close colleague of Shoemaker’s, Carolyn Porco, had decided to try and finally get the deceased scientist, who had wanted to be an astronaut in life but was disqualified for medical reasons, to the moon. Luckily, NASA also liked the idea of honoring Shoemaker by getting his ashes all the way to the lunar surface, and they called Celestis. “I got a phone call. A good friend of mine was the chief of staff and legislative liaison for NASA, Ed Heffernan,” says Chafer.

Heffernan asked Chafer if Celestis could work with them to find a way to get some of Shoemaker’s remains to the moon’s surface, because NASA wasn’t really in the business of burying people. Chafer was interested of course, but he want to make sure that this groundbreaking burial would set a precedent for future off-world memorials. “I said, ‘I want it to be a contract that is purchased from us.’ Now, we charged virtually nothing,” says Chafer. “I think we charged them the cost of the capsule that we sent out to Arizona.” Chafer said the capsule cost around $600.

On January 6, 1998, NASA’s Lunar Prospector blasted off for the south pole of the moon, looking for ice, and carrying an ounce of Shoemaker’s ashes. According to a memorial website set-up by Porco, the ashes were carried in a polycarbonate capsule provided by Celestis. It had been wrapped in a piece of brass foil, laser-etched with his name and dates over an image of the Hale-Bopp Comet; an image of Arizona’s Meteor Crater, where he had trained the Apollo astronauts; and a quote from Romeo and Juliet. On July 31, 1999, the mission ended when NASA deliberately crashed the craft on the surface of the moon, taking Shoemaker with it, and making him the first and only person to be buried off-world.

It’s taken decades for Celestis to pull off their now 14 missions. Luna 1, which is what they called the mission to transport Shoemaker’s remains, is still the only one that has landed remains on a different celestial body.

But according to Chafer, it won’t be the last. “I think we are entering an age of abundance in terms of commercial access to space.” The largest hindrance to space burial is finding a rocket to take even a small amount of remains out into space, but with the rise of independent programs such as SpaceX and Jeff Bezos’ Blue Origin, the number of opportunities to fly those secondary payloads is increasing, meaning that more people will have the opportunity be sent into the cosmos.

Accordingly, a number of competitors have sprung up in recent years offering similar services, though Celestis remains the only company to have actually accomplished a space burial. But the competition doesn’t bother Chafer. “If there weren’t competition, I’d be worried about the market,” he says. And the market definitely seems to be there, attracting what he calls “geeks, new agers, adventurers, and people who want the biggest send-off ever.” Celestis’s upcoming planned missions include a second lunar burial in the first quarter of 2018, and their first “Voyager” mission, which will attempt to send some remains forever into deep space.

Eugene Shoemaker might not be all alone on the moon for very much longer.
