Nothing really exciting.  They have the rover using some kind of high-tech microphone to listen to the helicopter "drone" flying around.  It also has video and subtitle comments.  It's historical, though, so it's extremely important!

You can even download it and use it (well, except for those anti-immersive subtitles) as the last known footage of the NPC heroes flying across planet X before they disappeared.  Not long after receiving the footage, NASA lost contact with the base that had recorded the footage as standard procedure and beamed it back to Earth.

That was x ago.  So now, the government informs the players that they TECHNICALLY had ANOTHER Capellan starship in their possession that they forgot to tell the players about!?   Another bureaucratic oversight!  Oh, and could the players investigate...?
