Nonprofit Wants to Launch 80,000-Year Mission to Alpha Centauri in 2029
Philip Johnston’s team seeks $15 million for a 1-kilogram probe that would carry human DNA and the Voyager Golden Record.
- On Tuesday, the nonprofit Fermi Explorer Mission announced plans to launch a probe toward the Alpha Centauri system by 2029, targeting humanity's nearest stellar neighbor about 4.4 light-years away.
- Philip Johnston, co-founder and president of the Fermi Explorer Mission, launched the project to confront the Fermi Paradox—the question "Where is everybody?" posed by physicist Enrico Fermi in 1950.
- Unlike the stalled Breakthrough Starshot mission, the team plans to use proven electric propulsion for the 155kg probe carrying a 1kg payload, with total mission costs estimated under $15 million.
- Launching in 2029, the probe will cruise at 24km/s for 79,800 years to reach Alpha Centauri; Johnston acknowledged that none of the current team will live to witness its arrival.
- Beyond Alpha Centauri, Johnston estimated that future missions to the Andromeda galaxy could cost around £73 million, with plans to send a spacecraft reaching our nearest galaxy in about one billion years.

How AI plotted an interstellar journey to Alpha Centauri
A nonprofit organization called the Fermi Explorer Mission announced today that it intends to launch a spacecraft to our nearest star system by the end of 2029. It’s a hugely ambitious mission—if all goes well, the spacecraft could take up to 80,000 years to arrive at Alpha Centauri, which is 4.4 light-years away. And the…
Fermi Explorer: Building the First Mission to Another Star?
The question of when to launch an interstellar mission has occupied us many times in the past. Specifically, how long do we wait so that travel times are reduced to something like the lifetime of a researcher working on the project? But there is another approach to all this. Someone is going to launch an […]
