Paper Abstract

In order to meet the requirements of Mars rover test, the Mars surface illumination environment simulation system was developed, which is mainly composed of optical subsystem, mechanical and control subsystem. It can simulate the solar elevation angle at a large angle and solar spectrum on Mars surface, etc. It is of great significance for development of Mars rover and the improvement of its ability to perform space exploration missions. After the system was developed, six indexes including irradiance, spectrum, solar elevation angle, illumination area, irradiation uniformity and irradiation stability were evaluated according to the test standards. The irradiance meets the requirement of 0.3 solar constant in the direction of vertical illumination. The spectrum meets the spectral requirements of the landing area; Mars surface illumination environment simulation system can be simulated 75° ~ 90° solar elevation angle, at the same time can be simulated illumination area of more than 10 m × 10 m; The irradiation non-uniformity of this system is ±14% ;Irradiation stability is expressed by irradiation instability, and the irradiation instability of the system is ±4.5% within 2 hours continuously. At present, the Mars surface illumination environment simulation system has participated in the Mars rover test, and the illumination effect has been affirmed by the test department.
