In order to measure the wind speed in Mars rover thermal vacuum test correctly, a low-pressure wind speed calibration system need to be developed. The purpose of this paper is to establish a low pressure-wind speed calibration system, and give an error analysis of it. In this paper, the Hot-bulb Probe calibration scheme, calibration conditions are...

In order to verify the correctness of the thermal control design, the Mars rover needs to conduct a thermal test on the ground during the construction of the Mars exploration mission. In the course of the thermal test, real-time measurement of the wind speed at low pressure is required. Therefore, it is needed to establish a low-pressure wind speed...

In Mars and other deep space exploration missions, the planetary atmosphere makes the difference in heat transfer characteristics on the planetary surface and on-orbit environment. In order to achieve the purposes of thermal model correction and spacecraft verification in extreme environment, Mars rover needs to be tested in a simulated Mars enviro...
