In 2016 Gros studied the feasibility of a low-cost interstellar mission, aiming to establish a biosphere of unicellular organisms on otherwise only transiently habitableexoplanets, fast-forwarding evolution potentially by several billion years.[6] The long mission duration would imply, according to Gros, that the Genesis Project would not have any tangible benefit for humanity. The initial acceleration could be achieved by laser propulsion, akin to that envisioned by the Breakthrough Starshot project, with passive deceleration at the target using magnetic sails. Overall, the probe would weight about 1.5 tons and travel at 0.3 percent of the speed of light.[7] An on-board miniaturized gene laboratory would synthesize the microbes.[8]
The precambrian biosphere established by the Genesis probe would evolve subsequently on its own, potentially to complex lifeforms. The concept of the Genesis Project carries a series of fundamental ethical and philosophical aspects, which have been discussed in the media.
