continued… We looked at the Atlantis Space Shuttle for a few minutes from different angles. She flew 33 missions, spent 307 days in space and flew 126-million miles. Her final flight finished on July 21, 2011.

Per the signs, Atlantis had three types of engines. The largest, or main engine, was used only for the first 8.5 minutes of take-off, and worked in conjunction with the rocket boosters to launch the shuttle into orbit. It had four turbo pumps, a computer controller and a network of ducts, wiring and valves and was able to withstand the release of 500,000 pounds (2,224 kN) of thrust. These fuel in the engines was -423 degrees Fahrenheit (-253 C), which was colder than Pluto. Inside the engine it was 6,000 degrees Fahrenheit (3316 C), hotter than the boiling point of copper. These engines had the most extreme temperature differential of all machines in the entire world.

continued… There was a large exhibit on Fisher Space Pens, which have been on every manned space flight since Apollo-7 in 1968. These remarkable pens are retractable, pressurized, all-metal, work in zero gravity, work underwater, write upside down, work in temperatures between -30 degrees and 250 degrees Fahrenheit (-35 to 121 degrees C), write on nearly any surface and last three times longer than an average ballpoint pen. The pens are made in Boulder City, Nevada.

Next was a holograph of former astronaut James Lovell talking to us. We don’t remember what he talked about, but, given the nature of the medium, we half-expected him to say “Your our only hope, OB-1.” He didn’t, though.

At some point, Eric had separated from Christi and Keith. As Christi and Keith were nearing the Command Module that they’d skipped earlier, they noticed a group of people coming out of the doors that Christi had noticed on our way in. She said “I knew we’d missed the first movie!” and quickly pulled Keith into the room to see the introductory movie. The set was a replica of the Control Room during the first moon landing.

continued… But we had a great view of the Saturn V from our table in the cafe. Looking towards the bottom of the rocket.

Basically above our heads.

Looking towards the top of the rocket.

continued... We followed the path to another building entrance. The first thing we saw when we opened the door was the bottom of the Saturn V rocket, which was diagonally mounted to the ceiling. A sign said the engines we were looking at were each 19 feet long, 12 feet and 3 inches wide at the widest point, weighed 18,500 lbs, and were fueled with a form of kerosene called RP-1 an liquid oxygen.

To the left of the photo was a large double-door that Christi remembered exiting from after the introductory movie on our last visit. The doors were shut, confirming in her mind that they’d changed how they’d routed guests. There were a few exhibits on the wall to the right of this photo.
