GreenCube Ceases Functioning Due to Radiation Damage

GreenCube (IO-117) Ceases Functioning Due to Radiation Damage

The GreenCube satellite, developed by S5LAB, has likely ceased functioning due to radiation damage. After a successful mission that exceeded expectations, the satellite is no longer responding to commands, and its onboard radio is believed to have been compromised by the harsh radiation environment in Medium Earth Orbit (MEO).

Approximately ten days ago, GreenCube experienced a reboot, and telemetry data from the event did not indicate any anomalies. However, the S5LAB team now suspects that the satellite’s radio was damaged, leading to the current communication blackout. MEO is notoriously challenging for satellites due to its high radiation levels, and GreenCube was not the only satellite affected. Several other CubeSats launched alongside it only lasted a few days, making GreenCube’s extended mission duration a remarkable achievement.

Despite ongoing efforts to send commands and reactivate the satellite, the team remains pessimistic about restoring GreenCube’s functionality. The satellite’s survival in the hostile MEO environment is seen as a testament to its robust design, but the likelihood of recovery is slim.

At this time, no successor to GreenCube is planned, primarily due to the infrequency of launch opportunities to MEO. Launches to this orbit are rare, which complicates the prospect of future missions.

In response to the satellite’s success and the interest it generated among radio amateurs, S5LAB has promised to host a webinar in collaboration with AMSAT Italia. The event will provide insights into the GreenCube mission, sharing the challenges and triumphs of the satellite’s journey. This is an opportunity for the amateur radio community to learn more about the satellite’s impact and the technical details behind its impressive mission.

While GreenCube’s operational life may have ended, its contributions to satellite technology and amateur radio will be remembered as a significant milestone.

AMSAT-DL ERMINAZ Mission Postponed to 2025

DK3WNLeave a comment

On Monday evening, August 19, 2024, just a few weeks before the planned launch date of the ERMINAZ payload, Rocket Factory Augsburg (RFA) conducted a “hot fire” test of the first rocket stage at its launch site at SaxaVord Spaceport on the Shetland Islands, during which all 9 engines were ignited. Unfortunately, this resulted in a serious anomaly that led to the complete loss of the first rocket stage. The repair work, fault analysis, qualification and delivery of a new first rocket stage will take some time, so that RFA now officially expects a launch in 2025.

The ERMINAZ mission is a joint effort between AMSAT-DL, AMSAT-EA and the Libre Space Foundation, with each organization flying its own satellites and jointly using the PicoBus deployer developed by Libre Space in the ERMINAZ mission.

 

Examples of the payloads include UNNE-1 and MARIA-G 1.5P PocketQubes from AMSAT-EA in Spain. They are both based on the HADES-D (SO-121) hardware currently in orbit and provide a repeater service for voice and data communications in FM and FSK modes. They were developed and built by AMSAT-EA in collaboration with private sector companies and with the participation of universities and educational centers. Both satellites will provide licensed radio amateurs around the world with the ability to conduct FM and FSK QSOs, including FT modes such as FT-4 and FT-8 or AX.25/APRS. The satellites will also transmit telemetry with their status, voice messages and CW. Both satellites have the amateur radio special call sign AM1HAD.

For detailed information on this ambitious and collaborative mission including the capabilities of all the various satellites included in this project, go to https://amsat-dl.org/en/erminaz-mission-postponed-to-2025/.
