Researchers at CU Boulder will soon set their sights on the heliosphere, a massive bubble in space that surrounds our solar system and shields it from incoming radiation.
NASA’s recently announced Interstellar Mapping and Acceleration Probe (IMAP) mission, which is slated to launch in 2024, will hover close to one million miles from Earth where it will observe the outermost edges of the solar system—the limits of our Sun’s influence on space.
LASP will play a major role in the nearly $500 million mission by leading IMAP’s scientific operations and designing an instrument that will fly on the spacecraft, detecting tiny particles of dust that flow through space.
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.
