  1. Graupel 1

    Our first high altitude balloon project. Mostly successful, but the GoPro batteries gave out too early so we repeated the mission.

  2. Graupel-2

    Our second high altitude balloon project. This time, we successfully filmed the entire mission and retrieved the payload safely.

  3. Sprite 1 - “Operation Whale Drop”

    Our third, planned, balloon project. This time with using a RC plane as the payload, with the intention of flying back to the launch site.
