Notice: for those in range, the Downlink Forwarder application has been finally completed! It is available on this page.

Mission data

This page shows the last value of all the housekeeping parameters of the spacecraft.
The data was collected by our two ground stations and by the beacon messages and downlink frames sent by the Amateur Radio community.
