Apollo 15 was the ninth manned mission in the Apollo program and the fourth mission to land on the Moon. It was the first of what were termed J missions — long duration stays on the Moon with a greater focus on science than had been on previous missions. Dave Scott, Jim Irwin and Al Worden explored the area at Hadley Rille. They carried the first LRV. July 26, 1971.
In Project Apollo - NASSP the Apollo 15 mission is available in Virtual AGC mode.
Virtual AGC mode
The Apollo 15 - Launch scenario in the Virtual AGC folder starts a new Apollo 15 mission. Unlike the other Virtual AGC scenarios Apollo 15 uses Artemis 072 as AGC software. This Colossus version has more features like P15 - TLI burn, but currently there's no pad load documentation nor source code, so expect more problems and limitations.
