I was indeed just there, good to know we have the same source of information here other than our memories. I believe the most logical choice might be Autumn. I mean we could use a Destroyer or Frigate but I think a cruiser would be a better design for an initially scientific expedition with back-up military equipment if needed. It can hold it's own.
