Mission Report (Michael Studinger, Mission Scientist)

Today's flight was a dh/dt repeat of the identical 15 October 2012 flight. We occupied straightened approximations of the Foundation and Support Force ice streams, and crossed several subglacial lakes in their upper portions. We also collected high-altitude gravity data across the Ronne Ice Shelf en-route to the survey area.

The two areas with weather suitable for science missions today were Hull Land and the Foundation Ice Stream area. Both, the GFS and AMPS model indicated low clouds over Hull Land that were also visible in the satellite imagery. The Foundation Lakes mission was lower risk from a weather point and we decided to launch. The satellite image showed a layer of low clouds over Foundation Ice Stream between waypoints FLA08 and FLA09. Both models predicted that this layer would dissolve before we reach the survey area which was not the case. We were not able to underfly the thick layer of low clouds and lost data from the optical sensors between these two waypoints. After turning behind waypoint FLA09 we encountered the expected sky clear conditions for the remainder of the survey line.

LiDAR data collection started 10/28/2014 16:58 UTC and ended at 19:28 UTC. In total we collected 2.5 hours of LiDAR data.

We connected to 3 classrooms today, reaching 51 students. On today's flight we were joined by NASA's Chief Scientist, Dr. Ellen Stofan and the U.S. Ambassador in Chile, Michael Hammer.
