We've intercepted a highly classified deep-space transmission!

We know the date the transmission began, but not the exact moment. The spacecraft broadcasts a cryptographic fingerprint of the time alongside its non-consecutive telemetry windows and five snapshots of its internal state, sampled at irregular intervals to resist eavesdropping.

Each sector is authenticated by the spacecraft's onboard Transmission Authentication Protocol. The signatures are included in the transmission log.

Can you decrypt the flag?
