Rosetta the comet chaser is reaching the end of its 10-year mission to catch-and land a robot on-a comet. Rosetta will also be the first spacecraft to accompany a comet as it enters our inner solar system, observing at close range how a comet changes as the sun's heat transforms it into a luminous apparition that has frightened and inspired people for centuries. Joel Parker, a director at the Boulder office of the Southwest Research Institute and deputy principal investigator for the ALICE UV Imaging Spectrograph onboard Rosetta, will describe how this project is helping us garner new knowledge about the origins of our solar system and perhaps life on Earth. Parker is also host and producer of the KGNU radio science show How on Earth. Image courtesy of NASA.
