Water Released from Moon During Meteor Showers

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. || 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. || 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.

The camera flies over the lunar terrain, coming in for close looks at a variety of interesting sites and some of the LRO data associated with them. Includes narration, music, feature titles, research sources, and the location and scale of the image center.

Six years later, the tour has been recreated in eye-popping 4K resolution, using the same camera path and drawing from the vastly expanded data trove collected by LRO in the intervening years.The tour visits a number of interesting sites chosen to illustrate a variety of lunar terrain features. Some are on the near side and are familiar to both professional and amateur observers on Earth, while others can only be seen clearly from space. Some are large and old (Orientale, South Pole-Aitken), others are smaller and younger (Tycho, Aristarchus). Constantly shadowed areas near the poles are hard to photograph but easier to measure with altimetry, while several of the Apollo landing sites, all relatively near the equator, have been imaged at resolutions as high as 25 centimeters (10 inches) per pixel.The new tour highlights the mineral composition of the Aristarchus plateau, evidence for surface water ice in certain spots near the south pole, and the mapping of gravity in and around the Orientale basin. || The camera flies over the lunar terrain, coming in for close looks at a variety of interesting sites and some of the LRO data associated with them.
