THEIA

THEIA is an Earth-imaging optical telescope payload built to test the capabilities of the ALLSTAR-1 Bus. The ALL-STAR/THEIA Mission launched on April 18, 2014 from Cape Canaveral, FL on the Falcon 9 v1.1 CRS-3 launch to the ISS. The 3U CubeSat was inserted into a roughly circular orbit at 325 km altitude, 51.7º inclination. Due to the large amounts of drag in the low-earth orbit, the mission lifetime is expected to be very short, about 4-6 weeks long. ALL-STAR/THEIA is currently projected to deorbit around May 23-25, 2014.

Unfortunately no communications with the ALL-STAR CubeSat have yet been confirmed. Several sightings of the beacon carrier signal at 2.4017 GHz appear promising, but no data has yet been recovered. This is partly due to a component malfunction at the local Longmont, CO ground station on April 22, 2014 that crippled the ground station tracking capabilities for the duration of the mission. 

In light of this, the ALL-STAR team reached out to several other collaborators with S-Band ground station equipment and received an overwhelming amount of support and enthusiasm in helping to track our satellite, both with S-Band receivers and optical telescopes. In particular, we would like to thank:
