Eternal Sunset

Eternal Sunset is the planned primary surface installation within the 1gSpace Proxima b mission architecture and the first fixed settlement site intended for long-duration human operation on the planet.

The site is defined within the planetary twilight zone, where comparatively stable thermal and illumination conditions are expected to provide the most favorable operating environment for early surface infrastructure. Its selection is not treated as a fixed assumption; the area is planned to be characterized first by ACEP from orbit, then reassessed by the ISV Innes crew through orbital survey, surface-access operations, and repeated lander-based inspection.

Eternal Sunset is therefore the first candidate site in a staged validation sequence. ACEP provides global reconnaissance, atmospheric data, terrain mapping, and preliminary hazard assessment. ISV Innes then expands that dataset with crew-directed orbital observation, landing-site verification, surface sampling, and operational testing of descent, ascent, and local mobility procedures.

After site certification, ISV Anglada is planned to deliver the equipment required for sustained habitation and early surface logistics, including power systems, construction assets, consumables, tools, autonomous support hardware, and pre-positioned operational infrastructure. ISV Proxima would follow as the colony transport stage, carrying the larger population element and the primary habitat systems required for permanent settlement.

Eternal Sunset functions as the supported initial foothold of the program: a transported, externally supplied base designed to stabilize surface presence, validate planetary operations, establish resource-handling procedures, and create the technical baseline from which later expansion can proceed.
