Astronaut Weightlessness Training

SciShow Space takes you behind the scenes of astronaut training, to show how crew members and their equipment are tested in microgravity, all while never having to leave Earth.

Inside the Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, technicians dressed in clean-room suits have installed a back shell tile panel onto the Orion crew module and are checking the fit next to the middle back shell tile panel. Preparations are underway for Exploration Flight Test-1, or EFT-1.
Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch later this year atop a Delta IV rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth’s surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

Chronicling the journey of the ISEE-3 space probe from its launch in 1978, the first-ever comet flyby, to a recent crowd-funded effort to contact and gain control of the decommissioned craft.

What’s It Like on Mercury?

SciShow Space takes you on a tour of Mercury, the sun’s closest friend, where a year is just a day and half long, and the surface holds many surprises — like ice!

Our Next Mission to Mars, and How the Sun Will Kill the Internet

SciShow Space shares the latest news from around the universe, including new details about our next mission to Mars, and a study that predicts a catastrophic solar storm may be more likely than we thought.

Watch the Delta Aquarids, and Meet NASA’s ‘Aquanauts’

SciShow Space preps you for the Delta Aquarids, a meteor shower, and explains what makes them so unique. Plus, join “aquanauts” on one of NASA’s least-known missions, a nine-day tour in its NEEMO undersea laboratory.

4 Important Lessons from the Apollo 11 Moon Landing

SciShow Space celebrates the 45th anniversary of the first moon landing by highlighting just four of the most important things we learned from the Apollo 11 mission. Subscribe!

     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.
