Now that we have a relay network around Moho, we can send a lander. Coincidentally, we have a new transfer window open.
Year 4, Day 215.
Payload: Lander Probe
Landing Stage: Ant I
Insertion Stage: Terrier I
Transfer Stage: Terrier IIb
First Stage and Boosters: Swivel Super Heavy
So here's the embarrassing thing. I forgot to actually check what the transfer parameters were, and this transfer required way more fuel than was included on the craft. At least we tested the Swivel Super Heavy launcher.
