Interested in science? Want to learn more about the latest technology breakthroughs in normal English, minus the jargon? Then Café Scientifique Pittsburgh at Carnegie Science Center is the place to be!
Café Sci is THE place in Pittsburgh where anyone interested in science can get together at a scientific hub to discuss today's science issues with experts, and best of all... you can ask your own questions! After a brief talk by our monthly guest speaker, the evening is dedicated to a question-and-answer session. Plus, enjoy our pub-type atmosphere with food and drinks available for purchase.
Dr. Scott Edgington
NASA Jet Propulsion Laboratory
Cassini, orbiting Saturn for over thirteen years, revolutionized our knowledge of the Saturn system and informed us of new places to search for habitable environments. Cassini sent back its final bits of scientifically unique data on September 15, 2017 as it plunged into Saturn’s atmosphere and vaporized, thus satisfying planetary protection requirements.
Join NASA scientist Dr. Scott Edgington as he discusses Cassini’s legacy of exploration and discovery. Edgington, who works for NASA’s Jet Propulsion Laboratory, will talk about how Cassini’s 22 orbits collected unique scientific data as the spacecraft roamed into unexplored regions between Saturn and its rings. These close orbits provided the highest resolution observations of both the rings and Saturn, and directly sampled ring particle composition, Saturn’s exosphere, and innermost radiation belts.
Thanks to Cassini, Saturn’s gravitational field was measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the outer layers of Saturn’s atmosphere, and the mass distribution in the rings. The magnetic field was probed to give insight into the nature of the magnetic dynamo and offered new clues as to why the magnetic field exhibits little, if any, axial tilt. In its final five-and-a-half orbits, Cassini's ion and neutral mass spectrometer sniffed the exosphere and upper atmosphere for molecules that escaped the atmosphere itself, and water-based molecules originating from the rings. This presentation will emphasize Cassini’s final phase and mission end in addition to highlighting recent results from the Ring Grazing orbits.
