The Altair lander (formally the Lunar Surface Access Module) was one of the principal vehicles of NASA's Constellation program. Together with the Orion Crew Exploration Vehicle, Ares I Crew Launch Vehicle, and Ares V Cargo Launch Vehicle, it would enable crewed missions to the lunar surface. In its crewed configuration, it was a two-stage lander. Its hydrogen-oxygen descent stage was dual-purpose, serving both as the landing stage and also to perform the braking burn to capture the entire Altair-Orion mission stack into low lunar orbit. The hypergolic-fueled ascent stage contained the main crew cabin, augmented by an optional airlock module which would remain attached to the descent stage. A cargo-only version with a simple unpressurized payload deck in place of the ascent stage was also planned, to support delivery of habitat modules or other large equipment

This model depicts Altair as designed in the final days of the Constellation program. The ascent, descent, and airlock modules are separate collections. The landing legs on the descent stage are rigged (a leg deploy level empty object controls their movement). Use of unapplied modifiers and instancing have been used to reduce model size and enable easy editing. All materials and textures are packed into the .blend file, and a zip file containing the needed image textures is also included
