e-st@r (Educational Satellite @ Politecnico di Torino) is a miniaturized satellite built by the Politecnico di Torino.[3] It is a 1-U CubeSat design weighing 1 kg.

Launch and Deployment

e-st@r was launched into Low Earth Orbit on the maiden flight of Arianespace's Vega rocket on the 13th Feb 2012. The launch was a multi-payload mission shared with LARES, ALMASat-1, Goliat, MaSat-1, PW-Sat, ROBUSTA, UniCubeSat-GG and Xatcobeo.

The satellite was successfully deployed into orbit, and the signal received by the team’s ground station and by amateur radio operators.[4] However, operations have been impeded by unexpected tumbling, and the satellite was put into safe mode.[5]
