DESCRIPTION:Speakers: Shane Byrne (University of Arizona)\n\n\n\nLong-term
  high-resolution orbital imaging at Mars has led to extraordinary advances
  in understanding martian ice and its connection to climate.  Icy seasona
 l phenomena such as flows in gullies\, avalanches\, and exotic defrosting 
 patterns characterize the present climate. Interannual variability over a 
 martian decade helps us deduce climatic averages and current trends. Obser
 vations of polar ice layers have characterized periodicities related to or
 bital change over longer timescales up to millions of years.\nHere\, I’l
 l describe the HiRISE camera and its continued mission to describe a dynam
 ic Mars over 20 years of observations\, with a special focus on north pola
 r avalanches.  HiRISE has uniquely high resolution and benefits from high
  signal-to-noise (even at the poles)\; a near-polar orbit that allows imag
 ing of almost any location within two weeks\; color bands that are sensiti
 ve to ice\; and sufficient imaging stability to construct high-quality met
 er-scale DTMs. The scientific impact of HiRISE owes much to rapid data rel
 eases and community targeting via our online tool HiWISH\, ensuring acquis
 ition and analysis of data relevant to today’s scientific questions. \n
