"During the night of 21 December 2015, a weak signal was received by the Rosetta spacecraft and examined by the mission team. Their analysis revealed that this was not a transmission from the lander."

This seems like something that deserves a little more elaboration.



That got me intrigued too. Found a bit more info on it in the comments of a reddit post here: https://www.reddit.com/r/space/comments/3xtu76/comet_lander_...


Thanks. This seems to be the key relevant quote from that thread: "The RSSI telemetry showed a single value sticking out of the noise, that's it."

So, just something random. Computer glitch, cosmic ray whacking something, or similar. Not aliens, alas.
