OIB completed the baseline priority ICESat-2 North mission. This mission was designed to overfly planned ICESat-2 ground tracks over a wide range of ice regimes near Thule. Some of the flightlines were centered on each of three beam pairs (left, nadir and right) in turn, sampling at least one of each beam pair during this mission. The east-west crossing line was designed to capture as many ascending/descending crossovers as possible. We also flew a particular flowline of Petermann Glacier which has been sampled intermittently during the ATM and OIB eras, overflying two GCNet sites in the process. The return leg to Thule was modified to overfly a segment of an Ultra-wideband radiometer (UWBRAD) flight line, at the request of Ken Jezek.
 
Weather was good for much of the mission with only a bit of haze on the southern portion of the flight line, though this did not significantly impact data collection. The DMS primary camera experienced a failure during the flight, the cause is still being investigated. The backup system successfully collected data during the flight with about 1-2 minutes of data lost. All other instruments performed nominally.
