AbstractThe proposed Micro-Mars mission can contribute substantially to the international Mars exploration programme within the framework of a future low-cost mission. The concept consists of an orbiter integrating a total scientific payload of 30kg including a light-weight lander of 15kg. The spacecraft will be launched as piggyback payload by an Ariane 5 ASAP with a total launch mass of 360kg. It will use a bipropellant propulsion system with 210kg of fuel and four thrusters of 22N, and four of 10N for orbit and attitude control. Further attitude actuation shall be performed by three reaction wheels and a gyropackage, a star sensor and a sun sensor for attitude sensing. Communication will be performed in S- and X-Band to Earth and in UHF between orbiter and lander.From a highly elliptical orbit with a periapsis below 200km, four instruments will perform high-resolution remote sensing observations and the payload consists of a camera system, a magnetometer, a dosimeter, and an ultrastable oscillator for radio science.The light-weight micro lander is a challenging technological experiment by itself. It is equipped with a suite of scientific instruments which will supplement the orbiter measurements and concentrate on the environment (temperature cycle, atmosphere, magnetosphere, and radiation).
