NASA's Lunar Reconnaissance Orbiter discovered a giant new crater on the moon's near side, formed by an asteroid or comet fragment around two years ago.
The crater, named after scientist Thomas McGetchin, is 728 feet across and up to 141 feet deep, three times bigger than the previous record-holder found by the same spacecraft.
Researchers say an impact this large happens only once every 132 years, making it a rare chance to study the moon's surface ahead of NASA's planned astronaut base.
