Scientists want to use this robot to measure quakes on the moon, but first they’re taking it to a volcano

When Neil Armstrong, Buzz Aldrin and Michael Collins departed the Moon on Apollo 11 they left behind an America flag, medals honoring two Soviet cosmonauts, and a seismometer. The seismometer sent data back for three weeks. Apollos 12, 14, 15, and 16 also left behind seismometers. The last data we have from them was broadcast back to Earth in 1977, just five years after the last Apollo mission. But until 2011, there wasn’t a computer powerful enough to parse the data to figure out what the moon was like on the inside.
