Yes, an Italian cube sat called LICIACube.

It will start broadcasting its data a little before midnight Eastern, though it might be months before everything is transferred. Because it is a cube sat (only 14 kg) the transmitters are not very powerful so I believe the transmission rate is low.




In general, does anyone know what protocol they're using to transfer large amounts of data back to earth? I'm wondering especially about error detection and correction.
