26 of May - Identified the CCSDS protocols used by TGO

The organizers have hinted that the message is in the telemetry signal of TGO, intermixed with other data that is sent normally by the spacecraft.

The participants now try to decode the telemetry signal. They have identified the CCSDS protocols used by TGO and obtained a binary file containing telemetry frames, and then produced another binary file containing the space packets which are contained in these frames. To make the space packet data more accessible, they have also made a CSV file which lists the sequence number, APID (roughly "type" of packet), length and contents of each space packet.
