As earth-bound visitors cross the elevated gantry bridge into the Center and enter the world of the future, the first awe-inspiring site they see is the rotunda-wrapping mural entitled Tour of the Universe.

The six-story mural, painted by world-famous space artist, Robert McCall, encircles the entire interior rotunda of the main floor. Utilizing 27,000 square feet of canvas, this phenomenal piece of artistry took six months to complete. It is believed to be the largest mural in Arizona.
