What’s the point of the interstellar Fermi Explorer mission?
Fermi Explorer, a proposed low-cost private mission to Alpha Centauri, seeks to address a question that’s already been answered
The Fermi Explorer mission, a proposed low-cost private interstellar probe, aims to fly by the sun's nearest neighboring star system, Alpha Centauri. While five spacecraft currently launched by NASA have ventured into the cosmos, none have set out towards Alpha Centauri. The Fermi Explorer mission, if realized, would be the first dedicated attempt to reach this nearby stellar system.
The mission's primary objective is to demonstrate that sending probes to other stars is technically feasible and affordable. With a price tag of less than $15 million, the spacecraft would weigh around 100 kilograms, carrying a one-kilogram payload and using solar-electric propulsion for its journey. The spacecraft would use a series of maneuvers to navigate out of the solar system and finally reach Alpha Centauri in approximately 80,000 years, a journey beginning in 2029.
The Fermi paradox, named after physicist Enrico Fermi, highlights the apparent contradiction between the ease with which intelligent life could explore the galaxy and the lack of evidence for such visits. The Fermi Explorer mission seeks to demonstrate that this paradox may not be due to a lack of capability, but rather other factors. By showcasing that interstellar travel is possible, the mission aims to contribute to ongoing discussions about the Fermi paradox and the potential for extraterrestrial life.
