After a successful Duna expedition I realized that without the lander the command ship had enough Δv for a brief visit to Ike to gather more of that sweet, sweet orbital science!
Thanks to a helpful gravity assist from the Mun, the crew made it back to Kerbn with a whopping 9 Δv left. If they didn't get enough aerobraking on the first pass it would have been next stop; deep space...
Thanks!
Here's some pics of the ship on the mission: https://feddit.uk/post/1090311
It's pretty basic really, 3 nervs, a lab and a command pod. Docked with the Duna lander which was just science, fuel and a lander can.
