Snow4Flow: Studying Glaciers from Arizona 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. Europa Clipper 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 & 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. OSIRIS APEX The OSIRIS-REx NASA mission, which is spearheaded by scientists at the University of Arizona’s Lunar and Planetary Lab, made history in 2020 when it successfully touched down on an asteroid named Bennu and collected a sample of rock to bring back to Earth for study. Now the heralded spacecraft is being prepared for a second mission: to the near-Earth asteroid named Apophis, which will come so close to impacting our planet in 2029 that it will be visible to the naked eye. The extended mission has a new name, OSIRIS APEX, and a new Principal Investigator, Dani DellaGiustina, who started out on the OSIRIS missions as an undergraduate at the University of Arizona.
