Purpose of Flight:Science
Comments:North Peninsula – The takeoff was delayed three hours because of a broke intercom wire in the pilot’s control yoke and enhanced security procedures at the airport that required everyone to be escorted to and from the plane. United States ambassador to Chile, Carol Perez, and her party flew aboard the DC-8 as observers. Two targets were dropped due to the flight shortening for reduced runway under repair. ATM: 100% data collection, instruments are all working well, no issues MCoRDS: 1.6 TB collected data, no issues Snow Radar: 1.2 TB collected data, instrument is working well, no issues Gravimeter: 3.9 GB collected data, instrument is working well, no issues

Mission Summary: 

Mission: Stancomb Inshore
Priority: Medium
Today we had a very successful mission, even after a deterioration of weather forecasts from the previous evening throwing us a curveball and requiring us to pick an entirely new mission, one which we previously had not considered, and a slight airport runway issue this morning. Regardless of these events we were still able to take off on time. 
The Stancomb Inshore is a land ice mission that was designed in 2018 and first flown today. This particular mission was designed for radar and lidar data collection along 4 ICESat-2 ground tracks and also along the grounding line flow of the Stancomb-Wills glacier. Today's mission was chosen based on clear skies in the region, and because the forecasts were correct, we were able to achieve 100% data collection for all instruments, with no weather, environmental factors or instrument issues encountered. Other higher priority missions were not obtainable based on poor and deteriorating weather conditions throughout the day. 
The 4 ICESat-2 ground tracks that were flown and their latency between the IS2 crossovers are listed below:
Line 0115, dt = 82 days
Line 0176, dt = 86 days
Line 0237, dt = 90 days
Line 0298, dt = 3 days

During the flight we were able to conduct 6 classroom chats with students in grades K-12 all across the country, from Alaska, Washington and Kansas; reaching a total of 148 students. 
As we finished up our data collection, we got to witness the Antarctic sunset over the Brunt ice shelf and some Weddell sea ice, which was breathtaking and a satisfying way to wrap up our successful mission.
