Moon engulfed in permanent, lopsided dust cloud

The moon is engulfed in a permanent but lopsided dust cloud that increases in density when annual events like the Geminids spew shooting stars, according to a new study led by LASP scientists at the University of Colorado Boulder.

The cloud is made up primarily of tiny dust grains kicked up from the moon’s surface by the impact of high-speed, interplanetary dust particles, said CU-Boulder physics Professor and LASP research associate Mihály Horányi. A single dust particle from a comet striking the moon’s surface lofts thousands of smaller dust specks into the airless environment, and the lunar cloud is maintained by regular impacts from such particles, said Horányi.

LASP instrument aboard NASA lunar mission set to impact moon

At the conclusion of a highly successful 130-day mission, the NASA Lunar Atmosphere and Dust Environment Explorer (LADEE) is planned to impact the surface of the moon on April 21, 2014. LADEE carries the Lunar Dust Experiment (LDEX), which is the latest in a series of dust detectors designed and built at LASP.

Lunar mission with LASP instrument receives extension

NASA has approved a 28-day mission extension for the Lunar Atmosphere and Dust Environment Explorer (LADEE). LASP provided the Lunar Dust Experiment (LDEX) onboard the satellite, which launched on September 6, 2013 and is now expected to impact the surface of the moon in late April 2014.

Due to accurate and efficient propulsion and guidance over the course of the mission to date, the spacecraft has more fuel remaining than mission operators originally expected. The extra propellant will provide an opportunity for LADEE to gather an additional full lunar cycle worth of very low-altitude data to help scientists unravel the mysteries of the moon’s tenuous atmosphere and dust environment.

LASP celebrates a year of exploration, discovery, and accomplishments

As 2013 draws to a close, it is amazing to reflect on all of LASP’s accomplishments in its 65th year! The last four months of the year were punctuated by launches to the moon, and Earth and Mars orbits for the LDEX, TCTE, and MAVEN instruments that LASP designed, built, and now operates.

LASP scientist to lead two new lunar programs

LASP scientist Mihaly Horanyi is an international leader in the study of lunar dust. Now Horanyi and his CU Boulder-based team are working to establish the Colorado Center for Lunar Dust and Atmospheric Studies, which will conduct both experimental and modeling research into the nature of dust on the moon and its impact for human exploration of the moon.
