Water Released from Moon During Meteor Showers: Animations

Scientists have discovered that water is being released from the moon during meteor showers. When a speck of comet debris strikes the moon it vaporizes on impact, creating a shock wave in the lunar soil. For a sufficiently large impactor, this shock wave can breach the soil’s dry upper layer and release water molecules from a hydrated layer below. The LADEE spacecraft detects these water molecules as they enter the tenuous lunar atmosphere.

Water is released from the moon during meteor showers, when micrometeoroid impacts breach the dry lunar surface and eject water molecules from a hydrated layer below.

This artist's concept animation shows meteor showers sweeping over the Earth and moon, causing the LADEE spacecraft (not depicted) to measure spikes in the lunar water signal.
