Purpose of Flight:Science
Comments:"Foundation-Academy IS-2 B", which is a new OIB flight and consists of four ICEsat-2 tracks crossing the Academy and Support Force ice streams. Prior to taxi, winds were light, but out of the southeast, requiring a runway 07 takeoff. This caused a ~20 minute delay in takeoff, due to incoming traffic and working out VFR/IFR clearances with the tower. Once getting airborne, the flight went smoothly. We did a ramp overpass at 1500ft AGL immediately following takeoff. The aircraft and science instruments all performed well. The #4 engine oil quantity indicator gauge was reading consistently low and is likely faulty or there is a faulty sensor. We had the Steelhead film crew onboard again. They conducted several interviews and gathered lots of video footage. ATM: 100% data collection, instruments are all working well, no issues MCoRDS: 100% data collection, instrument is working well, no issues Snow Radar: 100% data collection, instrument is working well, no issues Gravimeter: 100% data collection, instrument is working well, no issues Data: 100% data collection for KT-19, no issues

Mission Summary: 

Mission: Foundation Academy IS-2 B
Priority: High
IceBridge successfully completed the high priority land ice mission Foundation Academy IS-2 B today. As predicted, the outflow from the continent caused clear skies and no weather issues during our flight. Thus, we were able to have 100% data collection along the lines.
This OIB flight was designed to target the strong beam of each beam pair along ICESat-2 ground tracks that cross the channel of Academy and Support Force ice streams. This was also the first time this mission has been flown.
The 4 ICESat-2 ground tracks that were flown and their latency between the IS2 crossovers are listed below:
0238, t = 6 days
0939, t = 40days
0695, t = 24 days
0451, t = 8days
Outreach: Since today is Saturday and schools are not in session, no class chats were conducted during our mission.
Media: OIB hosted Steelhead a 3-person documentary crew during our mission today. Various instrument team members onboard were interviewed. Their feature length documentary ‘The Last Glacier’ will have ~15 minutes allotted to OIB.
Outlook: Tomorrow we will take a mandatory crew rest hard down day and plan to resume science missions on Monday, weather permitting.
