The next installment of my Iron Man Armor Mini-series is the Orbit-reaching member of the Stark Arsenal, the Mk.39, AKA Gemini, or Starboost.

Description of the Mk.39 Armor (from the Iron Man wiki);

"The Mark 39 (Mark XXXIX), also known by its names as"Gemini" and "Starboost", is a Sub-Orbital Suit, and was one of several new Iron Man Armors created by Tony Starkas part of the Iron Legion. The armor was created sometime after the Battle of New York.<sup>[1T

/url]The suit earned it's name the "Starboost", for having the ability to travel into sub-orbital ranges and for venturing into space, as it is derived from it's name. It was built with an armor that could stand the cold temperature and radiation in space and was built in with an oxygen tank to allow Tony to be able to breathe while he was in space."</sup>
