The COBRA (COntactless deBRis Action) concept was studied under ESA contract and then internally by ESA, as part of ESA ́s SysNova technology assessment scheme which uses “technology challenges” and competitions to survey a comparatively large number of alternative solutions. The concept was originally proposed by an industrial consortium led by GMV form Spain with Politecnico di Milano and Thales Alenia Space from Italy. The concept came first in response to a challenge for mission concepts and technologies capable of providing a contactless Earth-bound object orbit modification system.
