     Here, we have the Saturn V rocket, housed inside the Apollo/Saturn V Center at Kennedy Space Center near Titusville, Florida, just a few miles from Launch complex 39, where these beasts once roared into the sky.

     When we look at the enormous first stage of the Saturn V rocket, called an S-IC, we think “spaceship”. Truthfully, the Saturn V first stage never actually made it into space. The stage only burned for the first 150 seconds of flight, then dropped away from the rest of the rocket, all while remaining totally inside Earth’s atmosphere. The S-IC stage is merely an aircraft.

     Even more truthfully, the S-IC stage displayed here at the Apollo/Saturn V Center at the Kennedy Space Center in Florida, never flew at all. It is a static test article, fired while firmly attached to the ground, to make sure the rocket would actually hold together in flight. Obviously, these tests were successful, (e.g. she didn’t blow up), and she sits on our Apollo museum today. I wrote more about this particular stage in a previous post, (click here to view.)

     The rest of the rocket, the second and third stages, called the S-II and S-IVB stages, did fly into space. The S-II put the manned payload into orbit, and the S-IVB was responsible for initially propelling that payload from earth orbit to the moon, an act called “trans-lunar injection” (TLI).

     The particular rocket in this display, except for the first stage, is called SA-514. 514 was going to launch the cancelled Apollo 18 and 19 moon missions.

     The command/service module (CSM) in the photos is called CSM-119. This particular capsule is unique to the Apollo program, because it has five seats. All the others had three. 119 could launch with a crew of three, and land with five, because it was designed it for a possible Skylab rescue mission. It was later used it as a backup capsule for the Apollo-Soyuz Test Project.

On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first people to walk on the moon. The giant leap was made possible by decades of scientific research, rigorous testing, and new innovations spearheaded by NASA with collaborations by many other groups and organizations, one of which was GE. Among other contributions to the technology of the Apollo program, GE researchers developed a special silicon rubber for the astronaut’s boots. This week, to celebrate the 45th anniversary of the moon landing, GE, Android Homme and JackThreads collaborated on a new sneaker called The Missions, which Buzz Aldrin is wearing in the picture above. The sneakers feature lightweight carbon fiber used for jet engine components, and a hydrophobic coating similar to the materials that prevent ice from forming on wind turbines.
