Breakthrough Enceladus is a proposed privately fundedastrobiology mission byBreakthrough Initiatives founded byYuri Milner.[1] Its aim is to assess the possibility of life onSaturn's moonEnceladus.[2][3] NASA will be “providing expert reviewers and feedback on their design".Corey S. Powell, editor-in-chief ofDiscover magazine, reporting forNBC News stated that the mission was particularly notable as it would "rewrite the rules of space exploration," being potentially the first to find proof of complex life in the solar system, as it is "riskier than anything NASA would attempt on its own."[1]
Christopher McKay, a planetary scientist, atNASA Ames Research Center has compared Breakthrough Enceladus toMagellan’s circumnavigation of the globe, andRichard Byrd’s pole expeditions, that "would create a new paradigm for exploration.”[1]
The privately funded probe is estimated to take a decade to build and cost $60 million, while a NASA government funded approach could take over two decades and cost 15 times as much.[1] On 13 September 2018,Thomas Zurbuchen ofNASA signed a Pre-Phase A partnership agreement, with Breakthrough Prize Foundation's chairmanPete Worden to jointly create the mission concept and plan.[4][5]
The mission is the first privately funded deep space mission,[6] and if launched as planned prior toNew Frontiers Ocean Worlds andEuropa Clipper, it has the potential to be the first to discover the existence of ocean dwellingextra-terrestrial life.[7]
The flyby mission proposes to search for microbes in the plumes of water that are being ejected fromEnceladus's warm ocean, veiled under a layer of ice crust on its south pole.[8] According to a study published inGeophysical Research Letters, Enceladus's ice crust is believed to be two to five kilometers thick,[9] (thinner thanEuropa's ice layer, estimated to be 19 to 25 kilometers thick), and could permit a probe to useice-penetrating radar, to investigate the contents of the Enceladian ocean.[10]
The first private mission to deep space is gathering momentum.
Breakthrough Initiatives was investigating the feasibility of launching a probe that would look for signs of life in the plume of water vapor and other material wafting from Enceladus' south polar region.
