Candice Hansen-Koharcheck

Research and career In 1990 Hansen started working on the Cassini mission as part of the Ultraviolet Imaging Spectrograph (UVIS) investigation team. Hansen was part of the team within the Cassini mission that studies the plumes on Enceladus, one of Saturn's moons. This research has confirmed the idea that there are subsurface bodies of water on Enceladus.

Hansen retired from the JPL in 2010, but continued her work as senior scientist at the Planetary Science Institute in Tucson, Arizona. As part of HiRISE, Hansen studied the seasonal carbon-dioxide ice on Mars. She ran experiments on Earth using dry ice to study the possibility of carbon dioxide ice to be responsible for the gullies that were seen in the HiRISE images. She also co-authored a book titled 'Mars: The Pristine Beauty of the Red Planet ', a collection of HiRISE images.

Hansen was a collaborator on the Juno mission, and she was responsible for the JunoCam, the first interplanetary outreach camera coordinated by Juno co-collaborator Glenn Orton. The camera has produced the first close-up images of Jupiter's polar region. It was also used to capture images of volcanic plumes on Io, one of Jupiter's moons. For her work on the JunoCam, she received the NASA Outstanding Public Leadership medal in 2018.
