Although the composition of Duna's atmosphere is unknown, these values suggest that it may consist largely of carbon dioxide. The average molecular weight of Duna air is 42 g/mol, and its adiabatic index is 1.20. The pressure at the top of Duna's highest mountain peak is only 2.4 kPa. The datum level pressure on Duna is equivalent to that at an altitude of 14,975 m on Kerbin. Compared to the atmosphere of Kerbin, Duna's atmosphere has 1/15 th the mass, 1/15 th the surface pressure, and 1/9 th the surface density. Temperature and pressure of Duna's atmosphere as a function of altitude.ĭuna has a thin, cool atmosphere with a mass of approximately 3.0×10 15 kilograms, a datum level pressure of 6.755 kilopascals (0.067 atmosphere), and a depth of 50,000 meters. The trip may require a considerably higher delta-v budget for different orientations of Kerbin and Duna.Ī tutorial to get to Duna is available at the link. If the planets align properly, using a ballistic insertion burn from 100km, with proper aerobraking, a round trip from Kerbin to orbit around Duna and back requires ~1700 m/s of LKO delta-v, a relatively low amount compared to other interplanetary destinations. Duna is a terrestrial planet with a red-brown surface and polar ice caps similar to that of Kerbin.ĭuna's orbit has nearly the same inclination as Kerbin around Kerbol, making the planet one of the easiest to encounter.

It has one tidally-locked and large natural satellite, the moon Ike.

It is the Mars analog for Kerbal Space Program.
