LPI Seminar Series
Effective January 1, 2011, LPI seminars will be held on Fridays.
LPI seminars are held from 3:30–4:30 p.m. in the Lecture Hall at USRA, 3600 Bay Area Boulevard, Houston, Texas. Refreshments are served at 4:30 p.m. For more information, please contact Yann Sonzogni (phone: 281-486-2199; e-mail:sonzogni@lpi.usra.edu) or Ross Potter (phone: 281-486-2144; e-mail: potter@lpi.usra.edu). A map of the Clear Lake area (PDF format) is available here. The Acrobat Reader 8.0 is available from Adobe. This schedule is subject to revision.
See also the Rice University Department of Physics and Astronomy Colloquia and the Department of Earth Science Colloquia pages for other space science talks in the Houston area.

Massive Ice Avalanches on Iapetus Mobilized by Friction Reduction During Flash HeatingLarge ice avalanches on saturnian satellites exhibit a behavior similar to long-runout landslides found across the solar system: some mechanism (or mechanisms) apparently reduces the material’s friction, allowing the landslides to travel 10-30 times their drop heights (as opposed to ~2x for a more “normal” frictional regime). These landslides achieve immense runout lengths, even over variable slopes and topography. Landslides on Iapetus are some of the longest and most voluminous in the solar system, reaching lengths of 80 km. I will compare the long-runout landslides on icy satellites to their rocky cousins found on Earth and Mars, and discuss a possible friction reduction mechanism through flash heating.
