This is what a micrometeoroid striking a spacecraft sounds like
Last week, NASA reported that a micrometeoroid struck its Lunar Reconnaissance Orbiter in October 2014. NASA noted that the impact didn’t damage the orbiter, but made for a “fascinating example” for how the data from the spacecraft can be used in unexpected ways, including what that impact sounds like.
Scientists discovered the incident when they received a distorted image from the spacecraft on October 13th, 2014, which scientists determined was caused by a sudden movement from one of the orbiter’s three cameras. After ruling out normal equipment activity such as movement from the solar panels or antenna, they concluded that it must have been from a meteoroid.
