Scientists May Have Found First Moon Lander After 60 Years

A beach ball-sized spacecraft that bounced across the moon 60 years ago might finally be coming home, at least on our maps.

Luna 9 made history on February 3, 1966, when it became the first spacecraft to successfully land on the moon. The Soviet capsule opened four petal-like panels to steady itself, then snapped the first photos ever taken from the lunar surface. Days later, its batteries died, and scientists lost track of it forever.

Now, two separate searches think they've found it. Science communicator Vitaly Egorov spent eight years hunting for Luna 9, eventually recruiting his blog readers to help scan NASA's Lunar Reconnaissance Orbiter photos. The spacecraft is only two feet across, too small for current cameras to see directly, so the team looked for unusual pixels and matching landscapes instead.

"One day, the landscape looked familiar," Egorov told the New York Times. "I looked around and realized this was the same place Luna 9 had seen."

A second team used machine learning to search the same NASA images. They trained an algorithm on photos from Apollo landing sites, then let it hunt for similar features. Their study, published in January, identified smudges that could be Luna 9's hardware.

There's just one problem. The two proposed sites sit several miles apart. Egorov's location is roughly 15 miles from the Soviet Union's original estimate, while the machine learning team found theirs within three miles of it. Experts say both could be right, though, because scientists knew so little about the moon's surface in the 1960s.

The Bright Side

This mystery might get solved fast. India's Chandrayaan-2 orbiter will photograph both locations in March with a camera powerful enough to see individual pixels of Luna 9's four-petal design. That's four times the detail of current images.

Finding Luna 9 isn't just about closing a historical chapter. The lander can teach scientists how materials survive decades of exposure to the moon's harsh environment, crucial information as humans prepare to return. NASA's Artemis 2 mission will send astronauts to loop around the moon as early as next month, setting the stage for the first moonwalk in over 50 years.

Whether crowdsourcing or algorithms find it first, Luna 9 reminds us that some mysteries are worth the wait.
