Test Rocket 2 (TR2) was a rocket designed to replicate the avionics systems that would be on Karman Alpha. 

By launching TR2 in a two-stage configuration, we were able to verify that our flight computers could successfully perform stage separation and upper stage ignition.

The test launches of TR2 were vital in building up the team's experience prior to the launch of Karman Alpha in the Mojave Desert later in 2023.

Karman Mini was our first Avionics test rocket designed to fly with the MRAS board (Multi Rocket Avionics System) and a Raven altimeter. 

The main objective of Karman Mini was to provide cheap test flights for our MRAS avionics system.

We launched Karman Mini three times in total, in November 2022 and February 2023.
