The Space Station "Freedom" design was slightly modified in late 1989 after the program's Fiscal 1990 budget again was reduced — from $2.05 billion to $1.75 billion — when the design was found to be 23% overweight and over budget, too complicated to assemble, and providing little power for its users. The 1990 Space Exploration Initiative called for the construction of the Space Station "Freedom". Congress consequently demanded yet another redesign in October 1990, and requested further cost reductions after the fiscal 1991 budget was cut from $2.5 billion to $1.9 billion. NASA unveiled its new space station design in March 1991.
