Recreate the Ares program from the Martian in KSP with all stock parts. You'll need the following vehicles: Kermes - Nuclear powered, Ion thrusted, designed to ferry at least six Kerbals from Low Kerbal Orbit to Low Duna Orbit DLV - Duna Lander Vehicle, docked with Kermes at Kerbin, loaded with three Kerbals for descent to Duna on arrival DRV - Duna Return Vehicle, delivered to Duna ahead of the Kermes arrival, lands with empty tanks, fills them with an ISRU and returns three Kerbals to Low Duna Orbit Hab - Science Lab landed near the DRV on Duna ahead of Kermes Arrival, use a mobile processing module Rovers - Two, Two Kerbal Rovers landed near the DRV with docking ports allowing you to attach them and drive in tandem Mission Plan: Land one DRV on Duna at 'Site 1' Land the Hab and Rovers near the first DRV. Fly Hermes from Kerbin to Duna and enter Low Duna Orbit under Ion thrust Land second DRV on Duna at 'Site 2', dock with Kermes and transfer crew Load three of the Six Kerbals into the DLV and land them at Site 1 Return 2 of the three Kerbals to the Kermes in the DRV from Site 1 Last Kerbal joins the two rovers, and drives to Site 2 Last Kerbal boards the 2nd DRV and launches to Kermes Hermes returns to Low Kerban Orbit on Ion thrust All stock parts, but *hint* here's the ORBIT information for Duna: ORBIT { SMA = 380000 ECC = 0 INC = 0 LPE = 0 LAN = 0 MNA = 3.14156855428116 EPH = 20501.9955290068 REF = 6 }
