The poles of the Moon have emerged as enticing goals for future exploration, given their potential for harbouring water and other volatiles. So ESA and the European Space Resources Innovation Centre, ESRIC, challenged European and Canadian engineering teams to develop vehicles capable of prospecting resources within in these shadowy regions – then put their designs to the test in a realistic lunar analog environment. Five winning teams have now been selected from this challenge, receiving €75 000 contracts each to move their rovers forward to the next phase of the contest.
