Meet Orpheus—A Hopper Mission Built to Hunt for Life in Martian Volcanoes

Why It Matters

Orpheus could provide the first direct search for living microbes on Mars by accessing recently active volcanic vents where heat and water may still coexist, potentially delivering a breakthrough in astrobiology and reshaping future planetary exploration priorities.

Summary

Researchers at the SETI Institute have proposed Orpheus, a vertical take‑off and landing (VTOL) hopper designed to explore the volcanic fissures, pits, and vents of Mars’s Cerberus Fossae region. Targeting the young volcanic deposits and a specific vent (Vent #5) on the dome‑shaped volcano Cerberus Tholus 1, the mission would use a quadcopter‑style hopper equipped with a color camera, near‑infrared spectrometer, ground‑penetrating radar and a biosignature detector to search for extant life beneath the surface. The concept builds on the success of Ingenuity’s powered flight and aims to reach terrain inaccessible to wheeled rovers, but it currently has no funding or adoption plan, pending NASA’s focus on other Mars initiatives.
