Using data from the NASA New Horizons mission to Pluto, LASP scientists have made new measurements of interplanetary dust density. The data, collected from the CU-Boulder student-built Student Dust Counter (SDC) and the meteoroid detector on the Pioneer 10 spacecraft, represent measurements of the micro-sized dust grains from the Earth out to the present position of the SDC, at approximately 20 Astronomical Units (AU). One AU is equal to the average distance from the Sun to the Earth, or approximately 93 million miles (149.5 million km).

Using data from the NASA Cassini mission, a team of scientists led by LASP researcher Sean Hsu, has successfully modeled dust streams being expelled from Saturn at speeds of more than 62 miles (100 km) per second. The data, taken from the Cosmic Dust Analyzer (CDA) and the magnetometer on board Cassini, provide new information about the sources of the dust, as well as interactions within the mix of subatomic particles in which the charged dust is immersed, called dusty plasma.
LASP scientist Eberhard Grün has been awarded the 2011 Royal Astronomical Society (RAS) Gold Medal for Geophysics.
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.
