“We hope to be both the first to leave and the last to arrive at Alpha Centauri,” Philip Johnston, co-founder and president of the Fermi Explorer Mission, said in a statement today. “None of us will be here when this journey ends, and that is the point. It’s about taking the first achievable step and inspiring future generations to keep pushing beyond the limits we inherited.”<\/p>\n

Johnston is also co-founder and CEO of Starcloud, a company that plans to operate data centers in space<\/a>. He started the Fermi Explorer Mission with fellow Starcloud co-founders Ezra Feilden and Adi Oldean. Former U.S. Air Force officer Garrett Jamison leads day-to-day execution of the project. Some big names in the spaceflight world have signed on as advisors, including former Blue Origin<\/a> president Rob Meyerson and Matt Gialich, co-founder and CEO of the asteroid-mining company AstroForge<\/a>.<\/p>\n <\/p>\n The Fermi Explorer project is ambitious but achievable, according to Johnston and his colleagues. They want to launch a spacecraft to the three-star Alpha Centauri system \u2014 the sun’s nearest stellar neighbor, at about 4.4 light-years away \u2014 by 2029.<\/p>\n You may like<\/p>\n This directed trajectory will be a first. Though NASA’s Voyager 1<\/a> and Voyager 2<\/a> spacecraft are in interstellar space<\/a>, they’re not headed toward any particular star; rather, they’re journeying outward on the path they took to complete their “grand tour” of Jupiter<\/a>, Saturn, Uranus and Neptune.<\/p>\n The Fermi Explorer spacecraft will carry at least 2.2 pounds (1 kilogram) of payload, and its entire mission will cost less than $15 million, according to the team. If all goes to plan, the returns on that investment will be considerable.<\/p>\n Get the Space.com Newsletter<\/p>\n “The mission is intended to make the idea of interstellar travel real, and to encourage more people to confront one of humanity’s biggest unanswered questions when we look beyond our planet: ‘Where is everybody?’ (the Fermi Paradox),” the Fermi Explorer team said via X<\/a> today.<\/p>\n \n The proposed path of the Fermi Explorer Mission spacecraft. (Image credit: Fermi Explorer Mission)<\/p>\n The Fermi Paradox<\/a> takes its name from the famed physicist Enrico Fermi, who posited the “Where is everybody?” question in 1950. It has taken on greater significance in the past decade or so, as scientists have realized how common exoplanets<\/a> \u2014 potential abodes for life \u2014 are throughout our Milky Way<\/a> galaxy.<\/p>\n There are just three possible explanations for the paradox, according to the Fermi Explorer team:<\/p>\n What to read next<\/p>\n Human-like intelligence is rare throughout the universe<\/a>It’s not rare, but intelligent species don’t survive for longIt’s common and long-lasting, but intelligent aliens<\/a> generally don’t make themselves known to their cosmic colleagues (either by choice or by circumstance)<\/p>\n Launching a directed interstellar mission won’t solve the paradox, but it will give us some data that we didn’t have before.<\/p>\n “After the Fermi Explorer Mission, we will have more confidence both that is possible for intelligent species to leave for their nearest star<\/a> in a way that isn’t resource prohibitive, and that there are least some species that try to do it (namely us!),” team members wrote in an FAQ about the mission<\/a>. “This has the effect of throwing the Fermi Paradox into even greater focus.”<\/p>\n \n The Fermi Explorer Mission wants its spacecraft to be the first ever launched to Alpha Centauri, and the last to arrive. (Image credit: Fermi Explorer Mission)<\/p>\n The team says it envisions a small spacecraft, one that weighs just 220 to 440 pounds (100 to 200 kilograms) here on Earth. It will also likely employ electric propulsion<\/a>, which is more efficient than traditional chemical thrusters.<\/p>\n Electric propulsion is also a proven system, meaning the Fermi Explorer team isn’t relying on futuristic tech to travel to the stars. This has been a stumbling block for other interstellar projects, such as the apparently defunct Breakthrough Starshot<\/a>, which wanted to blast tiny sailcraft to Proxima Centauri<\/a> \u2014 part of the Alpha Centauri system \u2014 using powerful lasers. (That futuristic tech would be great if it worked, however; Breakthrough Starshot aimed to accelerate its nanoprobes to about 20% the speed of light, which equates to a roughly 20-year trip to Proxima Centauri.)<\/p>\n The details \u2014 who will build the spacecraft, for example, and what payloads it will carry \u2014 will be nailed down in the coming months. The project says it already has a proposal from one major satellite manufacturer that comes in under the $15 million cap.<\/p>\n![\"diagram](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/09\/Rnpr7Z6Tf2T59zjaZfGwGi.jpg\")
