Scientists have long known Mars has annual seasons just like Earth. LPL professor Shane Byrne describes how 20 years of observations by the U-of-A built HiRISE orbiting camera have given researchers new insight into what happens on the surface during the 687 Earth-day Martian year. 

Shane Byrne spoke with Tim Swindle, Professor Emeritus of Planetary Science at the University of Arizona.

Europa Clipper is a NASA mission to study Jupiter’s moon Europa, an ocean world that might harbor alien life beneath its icy crust. The University of Arizona’s Lunar and Planetary Lab has direct involvement with two of the spacecraft’s key instruments, which collectively will be able to map above and below the moon’s iceberg-like exterior to examine whether life could survive in the fathoms below.

Lunar and Planetary Laboratory's Regents Professor Alfred McEwen, Associate Professor Lynn Carter, and Researcher/Scientist Sarah Sutton discuss the Europa Mission and the work they are doing to discover more about  Jupiter's moon Europa.

LPL Professor Daniel Apai and  team member Karl Harshman discuss the Pandora Mission, it's purpose and the research process of this small satellite. It is the first astrophysics mission that will be complete operated from the U of A campus.

Snow4Flow is a new University of Arizona-led NASA mission to study arctic glaciers using advanced radar mounted on low-flying aircraft. Captained by Jack Holt, a professor at the University of Arizona’s Lunar & Planetary Lab, the mission’s goal is to improve climate modeling and to better understand glacial loss and its impact on sea level rise.
