A major challenge in the field of control is to achieve reliable, aggressive, high-speed control of autonomous vehicles. In space, this may involve spacecraft that need to land under harsh conditions, or even – in an extreme scenario – negotiating asteroid debris fields at high speeds. On Earth, the exemplar task that draws most attention currently is high-speed autonomous flight of drones. The application of optimal control on board limited platforms has been severely hindered by the large computational requirements of current state-of-the-art implementations.

Human exploratory missions to the Moon or Mars are widely considered as the next logical steps in human space exploration and, lately, settlement. Such space exploration or settlement activities involve humans spending long periods of time in space and, with increasing distance from Earth, no abort possibilities. Crews on such missions have to be self- sufficient, not only concerning food, drink and waste, but also with respect to medical treatment. Health issues are raised by the environmental conditions in space, such as the influence of altered gravity, radiation and isolation.

The main aspect of this study is to investigate the feasibility of the mission concept and the demonstration of the economic viability of a commercial payload delivery service to the Moon, as well as demonstrating the production of water/or oxygen with materials from the Moon. The study considered a payload delivery service that would be an end-to end service from Earth to a targeted location on the Moon, launched not later than 2025.

ALCHEMIST is a payload design created in order to produce water from lunar regolith so as to demonstrate the end-to-end process of hydrogen reduction of FeO on the lunar surface.
