The Soviet Union and the U.S. racked up a string of successful moon landings in the 1960s and 70s, before putting touchdowns on pause. China joined the elite club in 2013 and India in 2023. But last year also saw landers from Russia and a private Japanese company slam into the moon. An Israeli nonprofit crashed in 2019.

Next month, SpaceX will provide the lift for a lander from Intuitive Machines. The Nova-C lander’s more direct one-week route could see both spacecraft attempting to land within days or even hours of one another.

The hourlong descent to the lunar surface — by far the biggest challenge — will be “exciting, nail-biting, terrifying all at once,” said Thornton.

Besides flying experiments for NASA, Astrobotic drummed up its own freight business, packing the 6-foot-tall (1.9-meter-tall) Peregrine lander with everything from a chip of rock from Mount Everest and toy-size cars from Mexico that will catapult to the lunar surface and cruise around, to the ashes and DNA of deceased space enthusiasts, including “Star Trek” creator Gene Roddenberry and science fiction writer Arthur C. Clarke.

The Navajo Nation recently sought to have the launch delayed because of the human remains. saying it would be a “profound desecration” of a celestial body revered by Native Americans. Thornton said the December objections came too late but promised to try to find “a good path forward” with the Navajo for future missions.

One of the spaceflight memorial companies that bought room on the lander, Celestis, said in a statement that no single culture or religion owns the moon and should not be able to veto a mission. More remains are on the rocket’s upper stage, which, once free of the lander, will indefinitely circle the sun as far out as Mars.

Cargo fares for Peregrine ranged from a few hundred dollars to $1.2 million per kilogram (2.2 pounds), not nearly enough for Astrobotic to break even. But for this first flight, that’s not the point, according to Thornton.

“A lot of people’s dreams and hopes are riding on this,” he said.
