Astrobiology Missions

Enceladus Mission

According to src-esa-enceladus-life-mission-2025, ESA is pursuing an orbiter-lander mission to Saturn’s moon Enceladus under its Voyage 2050 strategic framework. The mission aims to investigate whether Enceladus’s subsurface ocean harbors life. Planned launch ~2042 with Saturn arrival ~2053. Requires two Ariane 6 launches with in-orbit docking.

Cassini-Huygens (1997-2017)

Built and operated the huygens-probe for titan in partnership with nasa (orbiter) and italian-space-agency (high-gain antenna). The probe’s January 14, 2005 surface touchdown remains the most distant landing in history. The partnership was foundational to ocean-worlds astrobiology and converted Cassini-Huygens into a treaty-level commitment that survived four U.S. budget cycles (src-cassini-huygens-ocean-worlds-2026-04).

JWST Partnership

ESA is a partner in the jwst alongside nasa and CSA.

Earth Explorer 13 (proposed)

earth-explorer-13 is an Earth-Explorer mission opportunity under selection. christopher-kyba is PI on a proposal for a dedicated night-lights satellite intended to detect fainter sources at higher resolution than the current VIIRS DNB capability — relevant here as a terrestrial-technosignature calibration platform for seti and exoplanet direct-imaging strategies (src-terrestrial-technosignatures-satellites-2026-04).
