Minispacecraft for a multiple-asteroid rendezvous mission
The development of the Multiple Asteroid Rendezvous Tracker and Explorer spacecraft, which is designed for the analysis of the composition and the motion of several main-belt asteroids, is discussed. The mission includes a laboratory lander craft (the main lab) and several minispacecraft. The main lab will be equipped with a complete sample analysis laboratory and multiple external sensors. Each of the minispacecraft, which are much smaller than the main lab and contain only a few instruments, is targeted to rendezvous with an asteroid, on which it will land and perform a preliminary surface analysis. This will identify the most scientifically interesting asteroid. The main lab will then be sent to this asteroid for performing a detailed analysis including soil sampling.
