NASA selects LASP-led IMPACT center to conduct dust-related research

NASA has selected eight teams to collaborate on research into the intersection of space science and human space exploration as part of the Solar System Exploration Research Virtual Institute (SSERVI). Among the teams is the CU Boulder and LASP-led Institute for Modeling Plasmas, Atmospheres, and Cosmic Dust (IMPACT).

The IMPACT center, led by LASP scientist and CU Boulder professor of physics, Mihály Horányi, is an international collaboration that includes partners from the CU Boulder departments of physics and aerospace engineering sciences, LASP, and the Colorado School of Mines. The focus of IMPACT center research is the dusty plasma environments around the moon and other airless bodies in the solar system.

In its final days, Cassini bathed in “ring rain”

On its last orbits in 2017, the long-running Cassini spacecraft dove between Saturn’s rings and its upper atmosphere and bathed in a downpour of dust that astronomers call “ring rain.”

In research published today in Science, LASP research associate Hsiang-Wen (Sean) Hsu and his colleagues report that they successfully collected microscopic material streaming from the planet’s rings.

The findings, which were made with Cassini’s Cosmic Dust Analyzer and Radio and Plasma Wave Science instruments, come a little more than a year after the spacecraft burned up in Saturn’s atmosphere. They stem from the mission’s “grand finale,” in which Cassini completed a series of risky maneuvers to zip under the planet’s rings at speeds of 75,000 miles per hour.

LASP director receives AGU’s highest honor

The American Geophysical Union (AGU) has selected LASP Director Daniel Baker as its 2018 William Bowie Medal recipient. AGU’s highest honor, the William Bowie Medal, is given annually to one honoree in recognition of “outstanding contributions for fundamental geophysics and for unselfish cooperation in research.”

Baker is one of 33 individuals to be recognized this year for their dedication to science for the benefit of humanity and their achievements in Earth and space science. Baker will receive his award during the Honors Tribute at the 2018 AGU Fall Meeting, which will take place on Wednesday, December 12, 2018, in Washington, D.C.

LASP research points to electrostatic dust transport in reshaping airless planetary bodies

A team of LASP scientists, led by University of Colorado physics professor Mihály Horányi, has conducted laboratory experiments that may bring closure to a long-standing issue of electrostatic dust transport, explaining a variety of unusual phenomena on the surfaces of airless planetary bodies, including observations from the Apollo era and the recent Rosetta mission to Comet 67P.

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.

LASP move eases crowding and supports collaboration

LASP Science Division personnel are moving to a new location on the CU Research Campus beginning October 14. According to LASP Director, Dan Baker, the benefits of the move are two-fold. Baker said, “LASP is a growing presence on campus. We are excited by the opportunity to expand our physical space to better address our current needs, while consolidating our science staff for more fluid collaboration.”
