Aetheris Orbis - Astraeus 2
Astraeus 2 – LR‑DM2#
Launch 01 Nov 2044 Dock 01 Jan 2045 (ISS) Return 31 Jun 2045
Mission Purpose – Extends the discovery series by testing long duration life support upgrades and delivering the habitat extension module that will host the robotic refueling station on the ISS.
Primary Objectives
- Operate an enhanced environmental control and life support system (ECLSS) for a continuous 60 day crewed stay, exceeding the baseline 30 day capability demonstrated on Astraeus 1.
- Transfer and install the habitat extension module onto the Aetheris Gateway LEO docking port, providing power, data, and mechanical interfaces for the future refueler.
- Validate remote health monitoring diagnostics for the ECLSS via the newly proven data relay link.
Key Milestones
- T‑0: Launch aboard the same heavy lift vehicle family used for Astraeus 1, ensuring commonality of launch operations.
- +2 mo: Docking and integration of the habitat extension module; crew initiates extended life support test.
- +5 mo: Completion of the 60 day endurance run; system performance logged and transmitted.
- +7 mo: Undocking, controlled re‑entry, and capsule recovery in the Gulf of Mexico.
Rationale & Impact – By confirming that crews can safely remain aboard an extended habitat for two months, Astraeus 2 guarantees that the Aetheris Gateway LEO can support the longer operational windows required for robotic refueling cycles. The installed extension module becomes the physical foundation for the Erebus refueler, turning the station into an active logistics hub.
