Hopefully they do. I was looking forward to trying to receive the data.

Hi Marcus, Unfortunatly, the rocket encountered a problem and the flight terminaison system had to be activated at about an altitude of 150km. As a consequence, CASAA-SAT will never transmit. We don't know at the moment if the lab will rebuild it for another launch.

Missed the launch! This is exciting news! Please keep us updated! Do you have a GNU Radio Flowgraph with which interested readers could monitor the satellite? TLEs?
