2 Overview Of Programs High Altitude Ballooning History Senior Design PSGC Seed Grant Taylor U. Balloon Workshop RockOn 2009 and RockSat 2010 ESMD Senior Design Lunar Regolith Excavator Challenge

3 Ballooning History In received a parts list after the Middle Atlantic States meeting from Mary Bowden Colorado Space Grant Workshop

4 Ballooning History In received a parts list after the Middle Atlantic States meeting from Mary Bowden Colorado Space Grant Workshop

5 Ballooning History Grabbed my local students and went to work in the garage!

6 Up, Up and Away!

7 Data

8 Other groups Used a beer cooler and hand warmers to keep phones warm. Cell phone worked over 18 miles up?

9 Introduction to Engineering Design First-Tethered Then Un-tethered Lost a few payloads- Atlantic Ocean, New Jersey, etc then decided d to.. Projects

10 Senior Design PSGC Seed grant Keep total budget < $5K Log and downlink data in real time Real-time tracking with GPS Two semester design Project followed NASA Design Procedures CoDR, PDR, CDR, etc

11 Conceptual Design

12 Nuts and Vlt Volts

13 Programming Code BS2 Sender Flowchart BS2 Receiver Flowchart

14 Hardware and Setup

15 Away We Go! Launch From TU Ambler FAA Clearance Willow Grove Naval Air Clearance Plot tracks for Possible Landing Locations

16 Away We Go!

17 Away We Go!

18 Data

19 Results Data Acquisition on Multiple Channels Data and GPS is down-linked in real- time. Use YAG antenna and Laptop to perform real-time track Next N t is real-time video and adaptive prediction of flight profile and landing in real-time

23 Multiple Data Pods

24 Launch Time! Two Teams: Blue and Yellow with identical multi-pod arrangements

25 Launch Time! Make sure you have enough helium for Make sure you have enough helium for Lift!

26 Up and Away

27 Up and Away

28 75,000 & 90,000

29 92,000 Pop and Deploy

30 Yellow Team Retrieval: It s OUT there somewhere!

31 Happy Five from PSGC

32 Blue Team Retrieval : It s UP there somewhere!

33 Temperature Data

34 Comments / Possible Explanations for Temps Surface Air Temperature Dropped During Flight (Early Evening Launch Time) But Probably Not by 20 degf Correct Lapse Rate During Descent (h < ft) Command Pod Data Shows Similar Feature Near 45,000 ft on Ascent & Descent (Probably Correct) Team 1 Pod Had Temperature Probe Embedded in Foam Bottom of Pod Likely Prevented Good Heat Transfer with Outside Air Cooled Slowly During Ascent Biased Measurement High Descent Rate Faster Than Ascent (See Below) Faster Heat Exchange with Outside Air During Descent Temperature Measurements During Descent More Likely Correct?

35 RockOn 09 & RockSat 10

36 Links NSTAR, or Nebraska Stratospheric Amateur Radio, have sent up several high altitude balloons within the past couple of months. Last, but certainly not least is the Amateur Radio High Altitude Ballooning group who have been sending up balloons since 2001!
