THE EXPLORATION AND EXPLOITATION OF COMETS AND ASTEROIDS

State of the Art

The exploration of minor bodies can contribute substantially to our knowledge of the solar system and to plan for the exploitation and manipulation of comets and asteroids. A potential low-cost exploration and prospection technology is offered by CubeSats. A variety of CubeSat platforms are available for applications around the Earth. Proposals exist to extend these capabilities to interplanetary space including asteroids. This extension requires the development of guidance, navigation and control (GNC), power and propulsion systems for deep space missions that account for the limited resources on board small spacecraft. A further key exploration technology is offered by landers. Landing on a rotating object in microgravity is a challenging task because of the lack of a priori precise information. The recent example of the ESAs cornerstone mission Rosetta deploying the lander Philae on a comet in 2014 demonstrates that key developments are required in GNC and system design in combination with prior prospection of the landing site to guarantee a successful landing. Once new information from prospection is available, the challenge is to use this information to improve our ability to manipulate the rotational and orbital dynamics of minor bodies.

Objectives

WP7 covers all activities related to exploration, and exploitation of asteroids and comets. It investigates the use of small platforms to characterise asteroids, binary systems, and develop technologies for close proximity navigation and landing on minor bodies.
