Starcloud Founders Announce Fermi Explorer to Send Tiny Probe Toward Alpha Centauri

Using proven solar‑electric hardware plus an AI‑derived perihelion pump the group says a 1 kg payload launched on a 2029 rideshare could coast to another star in roughly 80,000 years to test questions tied to the Fermi paradox.

Heading right over there.

Overview

  • The Fermi Explorer non‑profit was publicly announced Tuesday and is soliciting roughly $15 million, vendors and scientific or cultural payloads for a target 2029 rideshare launch.
  • The team says an AI‑assisted feasibility study found a perihelion 'pump' profile that uses close solar passes and solar‑electric propulsion over about 12 years to reach roughly 25 km/s, after which the probe would enter an ~77,000–80,000 year ballistic coast to Alpha Centauri.
  • Design calls for a very small craft with a 10 cm square, ~1 kg payload that would be actively operated for about 12 years with meaningful ground contact for roughly 18 months and routine tracking only until approximately Jupiter.
  • The mission plans to carry cultural items similar to Voyager’s Golden Record and has discussed including DNA samples, raising ethical and archival questions about what to send and who decides what represents humanity.
  • Early coverage shows inconsistent specs on mass, cost and cruise figures and experts note open technical questions about long‑term survivability, tracking after Jupiter and launch/vendor logistics as fundraising and partnerships proceed.
