Photos

• Hey, where are the photos from SB3?

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. Media:AccelerometerDumpfile 2010-11-13 18-24-41.csv.gz
