+# Blue Moon Mark 2
+
+**Type:** Human Landing System (HLS)
+**Developer:** Blue Origin
+**Status:** Development (as of March 2026)
+**Program:** NASA Artemis
+
+## Overview
+
+Blue Moon Mark 2 is Blue Origin's commercially developed Human Landing System for NASA's Artemis program. It serves as a potential backup to SpaceX's Starship HLS for crewed lunar landing missions.
+
+## Development Status
+
+As of February 2026, Blue Moon Mark 2 remains in development with uncertain schedule certainty. NASA framed it as "if Starship isn't ready, Blue Moon could be the only target" for Artemis III LEO docking tests, suggesting Blue Origin's readiness is also uncertain.
+
+## Program Role
+
+Blue Moon Mark 2 is part of NASA's dual-HLS strategy, providing redundancy against single-provider dependency on SpaceX's Starship HLS.
