The J-series of Lunar Modules were the extended stay vehicles used on
Apollo 15, 16, and 17. They also carried the Lunar Roving Vehicle in
the bay next to the descent ladder. I tended to concentrate these
photos on the LRV bay itself, with a few other shots thrown in for
good measure. This was on display in the US Space and Rocket Center
in Huntsville, Alabama. I've also included some drawings from the
Apollo 15 Final Lunar Surface Procedures document which shows
how the rover was unstowed from the LM, along with the layout of the
MESA.
