Thermal Behavior Study for Mars Balloon

Mars atmosphere is suitable for the use of balloons.In this paper the special thermal environment of Mars thin atmosphere is analyzed,and two prototype super pressure balloons with different film radiation properties are designed.Then a model for the thermal behavior of the balloons is established with certain simplifications.The temperature distribution of the balloons in several cases are simulated,such as warm and cold temperatures,any location and special conditions.The results show that improvement of the design of the film radiation properties will enable the balloon to meet the specific thermal behavior demands of Mars.
