Blast from the past. The Altair Lunar Lander via Fuck Yeah Spaceships Tumblr.

Note:  When the Constellation program was "reconfigured" and given the new mission of landing on an asteroid (I still don't get that...the moon is a stable source of everything we could get from asteroids...its like they just wanted to do something different instead of actually harvesting resources) instead of the moon, alot of work had been thrown away with the blink of an eye.  Exhibit number one is the Altair Lunar Lander.  Its just like the Orion space capsule.  A step back to the work that was proposed for the follow on to Apollo by the greats that put us on the moon.  Notice that they chose an evolutionary path instead of seeking to be revolutionary.  The US military should take note.
