Iron Man (Space Armor)
When Iron Man needed to investigate mysterious microwave transmissions from space, he introduced his first set of space armor. Designed to operate in zero-G conditions, this bulky armor provided the necessary protection and propulsion for space flight and operations. Iron Man would test his new armor to the max of its abilities while dealing with the misguided scientist Sunturion and his solar power station.
The first space armor (seen here in Minimate form) premiered in Iron Man #142. There have been several different models since this one was introduced.
