This video shows the Apollo 15 lunar landing, flown with NASSP 8.0 Alpha in Orbiter 2016. As always the Virtual AGC is used, running the Luminary 1E software, which was flown in the Lunar Module computer (LGC) of Apollo 15 to 17. As in my previous Apollo 11 video the whole process from Powered Descent Initiaton to post-landing is shown, this time also with some annotations.
Highlights of this video are the amazing terrain, the Montes Apenninus, the Mons Hadley massif and the LM flying directly over Mons Hadley Delta. During the landing Hadley Rille can bee seen in the background. Highlight in terms of NASSP development is certainly to see Luminary 1E (specific version number Luminary 210) working. Luminary 1E can use a terrain model to translate the landing radar measurements to state vector updates and by flying over the 11,000 feet Mons Hadley Delta this terrain model is certainly necessary. Luminary 1E is one of the new LGC versions that became available for the Virtual AGC project through the LGC developer Don Eyles, who had a bunch of these 1700 pages listings in his private collection.
Also for the first time the Rate-of-Descent (ROD) mode, Program 66, is demonstrated. This mode was used for all actual lunar landings. It's a computer assisted mode, with a switch used to control the descent rate, which the computer then translates into throttle commands for the Descent Propulsion System (DPS). When no joystick inputs are done then the LM is in attitude hold in the ROD mode. The astronauts also could have performed a fully automatic landing with the computer or a fully manual landing.
