NASA launched a rocket 54 years ago. Has it finally come home?
Surveyor 2 crashed on the moon in 1966. Astronomers think they have spotted a piece of the mission that kept going deeper into space. Since September, scientists around the world have been investigating 2020 SO. Vishnu Reddy, a planetary scientist at the University of Arizona's Lunar and Planetary Laboratory, and Adam Battle, a graduate student there, compared observations of 2020 SO with a known Centaur rocket booster orbiting just a few hundred miles above Earth. The optical colors matched, Reddy said, but sealing the deal would require infrared observations of 2020 SO. At those wavelengths, it's a "slam dunk" to compare objects' compositions.
