Spaceblimp-5 Launched: July 9, 2011
Summary
This time we were going for altitude, and we got it! The max recorded altitude was 118,533 ft! (Getting us the 16th highest altitude record on [ARHAB.org] !)
The launch site was: Strasburg VA, in a open area near the town on Rt 11, near the I-81. Lat: 38.9968 N Lon: 78.3508W
The path the balloon took was pretty strange, with the wind shifting between ascent and descent, and so we had a lot more driving to do than usual. The primary GPS/radio worked perfectly, and we got super-lucky with the recovery, picking up the package ~15 minutes after it hit the ground. The video camera overheated and failed before launch (booo!) and we're still working on the instrument data, but all signs point to some new and interesting results at the highest altitude we've ever run.

Launch Plans
| Planned launch date: | Saturday, July 9, 2011 |
|---|---|
| Launch time: | 10:00 AM, Launch should take less than an hour. |
| Launch Location: |
Strasburg, VA |
| Coordination/Talk-in: | 146.685 MHz simplex (this might change, please monitor Twitter (@HacDCSpaceblimp) and mailing list for updates. |
| Planned Altitude: | 120,000 Feet |
| Planned Ascent Rate: | 1,000 feet/minute |
| Planned Descent Rate: | 1,000 feet/minute |

| Secondary Beacon: | GSM mobile phone modue, uBlox GPS |
| Payload: | 9 DOF IMU, Geiger counter, temperature, pressure, humidity, and light sensors |
Payload
Radios
There were two radios on board the blimp that transmitted out the GPS data:
- The primary radio was tied to the GPS and transmitted out to a network of amateur radio enthusiasts who then passed the location information on to get mapped here: APRS.fi. We also ran some custom software that passes this data on to a Twitter account (once per minute!) which you could follow on your phone: DC Spaceblimp Primary Twitter Feed. (Click the link in the Twitter to pull up a map!)
- The secondary radio was actually a GSM cell phone module, and broadcasted its data when in range of a cell tower. It broadcasted both GPS data for tracking, and a lot of the sensor data for science. It also twittered through Society Of Robots Twitter Feed.
Cameras
The payload contains a couple cameras:
- a video camera (Canon Zi6)
- a still camera (Canon Powershot A-480) running custom firmware to get better exposures from space
Instrumentation
and a lot of instrumentation:
- a geiger counter
- 9 degree-of-freedom IMU (Inertial Measurement Unit on Wikipedia)
- high-speed (50 sample/sec) accelerometer
- internal and external temperature sensors
- humidity sensor
- air pressure sensor
- IR and visible light sensors
- a solar panel, hooked up to measure the voltage
