On board Intuitive Machines’ Athena spacecraft, which made a moon landing on March 6, were cutting-edge MIT payloads: a depth-mapping camera and a mini-rover called “AstroAnt.” Also on that craft were the words and voices of people from around the world speaking in dozens of languages. These were etched on a 2-inch silicon wafer computationally designed by Professor Craig Carter of the MIT Department of Materials Science and Engineering and mounted on the mission’s Lunar Outpost MAPP Rover.

Dubbed the Humanity United with MIT Art and Nanotechnology in Space (HUMANS), the project is a collaboration of art and science, bringing together experts from across MIT — with technical expertise from the departments of Aeronautics and Astronautics, Mechanical Engineering, and Electrical Engineering and Computer Science; nano-etching and testing from MIT.nano; audio processing from the MIT Media Lab’s Opera of the Future and the Music and Theater Arts Section; and lunar mission support from the Media Lab’s Space Exploration Initiative.

While a 6-inch HUMANS wafer flew on the Axiom-2 mission to the International Space Station in 2023, the 2-inch wafer was a part of the IM-2 mission to the lunar south polar region, linked to the MIT Media Lab’s To the Moon to Stay program, which reimagines humankind’s return to the moon. IM-2 ended prematurely after the Athena spacecraft tipped onto its side shortly after landing in March, but the HUMANS wafer fulfilled its mission by successfully reaching the lunar surface.

“If you ask a person on the street: ‘What does MIT do?’ Well, that person might say they’re a bunch of STEM nerds who make devices and create apps. But that’s not the entire MIT. It’s more multifaceted than that,” Carter says. “This project embodies that. It says, ‘We’re not just one-trick ponies.’”
