Can I ask what the sensors are telling me? I'm afraid if I make that part up, it could run counter to the plot and I'd have to edit it later...
Don't worry too much about getting it wrong - we try to let our missions be player-run as much as possible, and would rather work around you than make you work around us
there's no punishment for being "wrong" (and there's no real "wrong", only future plot devices)
As for what sensors are saying though, for now only what's been said - surprise gravity well out of nowhere. Feel free to experiment with how it behaves, and what's in or around it though, it may not be your typical natural phenomenon...
