A space rock several hundred metres across is heading towards our planet and the last-ditch attempt to avert a disaster - an untested mission to deflect it - fails. This fictional scene of films and novels could well be a reality one day. But what can space agencies do to ensure it works?
ESA is appealing for research ideas to help guide the development of a US-European asteroid deflection mission now under study.
Concepts are being sought for both ground- and space-based investigations, seeking improved understanding of the physics of very high-speed collisions involving both man-made and natural objects ib xqoqu.
