This week’s challenge is Land on Duna
Primary: Land a vehicle (crewed or uncrewed) on Duna.
Stretch: Land a crew on Duna, then return them safely to Kerbin.
Jeb Level: Land a crew on Ike, take a picture of them with Duna visible in the background. Then land them on Duna and take a picture of them with Ike in the background. Then fly them all home to Kerbin.
Val Level (Watney Edition): Land an empty Kerbin return vehicle on one of Duna's polar ice caps. Land a crew somewhere other than the ice caps. Drive that crew, using either a wheeled or aerial vehicle, from the second landing site to the first one. Then return to Kerbin.
