6. 2013 Summer Design Program Waiting for it to land… 6 Waiting at the Harlowton Gas Station The gas station was called “Ray’s”, another tribute to the grad students.

7. 2013 Summer Design Program Balloon Recovery (7/23/13 – 11:40am) 7 0.8 mile hike from the road The entire system is intact The payload was still running Reunited Randy Berk

8. 2013 Summer Design Program Data Check (7/23/13 – 12:02pm) 8 A curious moose also wants to see… The team nervously awaits to see if they collected data…

9. 2013 Summer Design Program Science Data !!! 9 Expected (from 2009 flight) Measured The SparkFun Geiger counter data matched the flight data from 2009 verifying it was correct. The SSEL Geiger counter data had a similar profile vs. altitude. The difference between the two Geiger counts was due to the different tubes used. The SparkFun had a larger diameter tube, a larger window and a higher sensitivity (detect > 7MeV). The SSEL Geiger counter was selected for higher energy events in orbit so it had a smaller diameter and lower sensitivity (detect > 12 MeV). The silicon-based sensor detected two events during ascent. These are suspected to be due to heavy ion strikes. Heavy Ion Strike
