LR-101 Rocket Engine

Mark has an LR-101 on its full gimballing mechanism. This engine is a thing to behold, and probably my favorite artifact of his.

The thrust chamber freely gimbals, which sometimes complicated moving it around for photography, but other times made it simpler (as all I had to do was move the thrust chamber).

The same basic engine was used on both the Atlas and Thor (the main difference being the mount frame); I am uncertain as to which version this vernier is. This does appear to be an early LR-101, both by its low serial number its lack of a hypergolic igniter container.

See my page with additional LR-101 vernier engine information.
