Spaceblimp 3 went up with two still cameras and a non-functioning video
|
|
|
|
camera. There are tons of neat pics from both. These links get you into
|
|
|
|
the series right before liftoff.

These are about as far out as we got before the balloon popped:

|
|

And then, recovery:

## The Dataz! (Telemetry)
|
|
|
|
|
|
|
|
- Accelerometer data. Unfortunately, it looks like there was a bug in
|
|
|
|
the code and the second half of the data overwrote the first. Anyway,
|
|
|
|
here it is. It's 100 samples per second, start time unknown, but it
|
|
|
|
looks like it captures the pop, some freefall, and the landing.
