Rome, April 30, 2024 – AMSAT Italia is proud to announce the acquisition of the quote of property of the IO-117 “GreenCube” satellite. The other part of the property remains on behalf of “Sapienza University”, Rome, Italy.

A collaborative work of the parts will let the satellite continue the amateur radio operations after the completion of the primary scientific mission. This will definitively avert the satellite decommissioning process by transferring the legal responsibility of the satellite from the Italian Space Agency to AMSAT Italia. Even formally and legally, the satellite, already known with its original name of GreenCube, becomes for the exclusive use of amateur radio. The scientific community continue the study of the behavior of this type of satellite placed in MEO orbit.

GreenCube was designed and developed by Sapienza University, ENEA and University of Naples Federico II for the Italian Space Agency. AMSAT Italia contributed to design the digipeater and supported amateur radio operations. IARU coordinated the use of the operations in the amateur radio frequency bands.

The satellite was carried on the qualification flight of Vega-C launcher on July 13, 2022 from the French Guiana Space Center in Kourou. On October 29, 2022, the on-board digipeater was activated, allowing GreenCube to become the first ham radio satellite to operate in a MEO orbit. Being a radio amateur worldwide success, AMSAT officially designated the satellite as Italy-OSCAR 117 (IO-117).

AMSAT Italia and Sapienza Space Systems and Space Surveillance Laboratory – S5LAB- are now committed to operate the satellite and to continue to offer the service to the amateur radio community.

S5Lab announcement on X that GreenCube is to cease operation

At 1622 GMT on Thursday, January 25, 2024 @S5Lab posted on X that the GreenCube IO-117 Digipeater would be permanently deactivated on February 5.

Designed and developed by students of Sapienza University of Rome, GreenCube IO-117 was the first satellite to carry an amateur radio payload into Medium Earth Orbit (MEO) – 6,000 km.

The S5Lab post on X said:

Dear Friends,

After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will pergorm the passivation operations for the satellite.

The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.

We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.

Thanks once again for the unbelievable memories shared together… See you soon!

The GreenCube Team at S5Lab
