NASA AERONAUTICS AND SPACE REPORT - THIRD MANNED SKYLAB

Creator: Natl Aeronautics And Space Administration

Description: Skylab: A Home in Orbit 00:00:00 NASA presents a special Aeronautics and Space report about Skylab, which orbits Earth every 93 minutes, 275 miles out. 00:00:16 Inside Skylab, men work and sleep, experiencing 15 sunrises and sunsets daily, and must exercise to counteract the effects of weightlessness. 00:00:31 Skylab is the working and living quarters for three three-man crews, providing valuable insights into human endurance in space. 00:00:44 Six astronauts have already completed missions of 28 and 59 days, and the next crew is preparing for the third and final Skylab mission. 00:00:54 - 00:02:10 Third Manned Skylab Mission 00:00:54 The third manned Skylab mission is introduced with its crew: William Pogue, Edward Gibson, and commander Gerald Carr. 00:01:05 The mission's primary objectives are medical flight physiology, solar observations, and earth resources observations. 00:01:22 Observations from Skylab provide valuable data and pictures of Earth's land, seas, clouds, rivers, and mountains to help manage resources. 00:01:40 As a winter flight, the mission will gather extensive snow cover data, which is crucial for hydrologists studying water supply, and observe environmental pollution from winter heating. 00:02:10 - 00:03:07 Eating in Space 00:02:10 Eating in space has changed significantly over the years, both in what is consumed and how it is eaten. 00:02:22 The position assumed while eating in space does not affect the ability to swallow, as astronauts have successfully eaten while floating upside down. 00:02:33 Early concerns about swallowing in zero gravity, as recalled by John Glenn, have been overcome, with astronauts now comfortably enjoying their food. 00:02:56 Astronauts now use spoons and other utensils, a stark contrast to the early days when eating was thought to be only possible from tubes or squeeze bottles. 00:03:07 - 00:05:53 Skylab Pilot William Pogue and Materials Processing in Space 00:03:07 William Pogue, Skylab pilot, is particularly interested in experiments involving manufacturing in space, which scientists believe could lead to materials with significantly increased strength and reliability on Earth. 00:03:31 The Materials Processing Facility on Skylab allows for various hardware experiments, including welding, brazing, heating materials to stimulate crystal growth, and a Zero Gravity Flammability Experiment. 00:04:26 Experiments in zero-gravity welding, brazing, and sphere forming are being conducted using an electron beam, with researchers analyzing the quality of welds and the formation of perfect spheres from molten metal. 00:05:02 Flammability experiments will be conducted by igniting different samples, such as Mylar, Teflon, and paper, to observe how flames behave in zero gravity and whether they self-extinguish due to gas accumulation. 00:05:53 - 00:08:08 Solar Physics and Discoveries from Skylab 00:05:53 Dr. Edward Gibson, a science pilot, explains his focus on medical and solar telescope operations, having written a textbook on solar physics to better understand the subject. 00:06:35 The first Skylab flight captured unprecedented photography of the sun's corona, leading to significant insights into the sun's intermediate region and its impact on Earth. 00:07:20 Researchers gained extensive knowledge about solar flares, their effects on radio communications, and high-energy emissions observed near Earth. 00:07:40 Unexpected discoveries included numerous bright points and coronal holes in the sun's atmosphere, which are expected to advance our understanding of basic physics. 00:08:08 - 00:09:39 The Sun's Influence and Practical Applications 00:08:08 The sun is our primary energy source, and its evolution has influenced the entire course of our own evolution, including biological effects from high-energy radiation. 00:08:34 To understand the potential for life elsewhere in the solar system, we must first comprehend the radiation history of the entire solar system, which necessitates understanding the sun. 00:08:46 Our technologically oriented society relies heavily on basic knowledge in physics, such as atomic and nuclear physics, which are crucial for future energy sources like magnetohydrodynamics. 00:09:25 The sun serves as a giant astrophysical laboratory, allowing us to conduct experiments and learn fundamental principles that are difficult to replicate on Earth. 00:09:39 - 00:12:09 Comet Kohoutek 00:09:39 The Skylab crew anticipates observing Comet Kohoutek, a potentially brighter comet than Halley's Comet, between November and January. 00:09:52 The presence of the Skylab crew in orbit during Comet Kohoutek's approach is considered fortunate for science, especially for those studying the solar system's formation and primordial matter. 00:10:50 Scientists are eager to observe Comet Kohoutek with advanced instruments in orbit, offering a unique opportunity compared to ground-based observations of other comets. 00:11:45 Comet Kohoutek is expected to be a very bright sphere with a long tail, potentially covering a significant portion of the sky, creating a dramatic natural spectacle. 00:12:09 - 00:14:03 Skylab's Accomplishments and Future 00:12:09 Skylab has successfully demonstrated that humans can endure and perform tasks for prolonged durations in the weightlessness of space. 00:12:33 Astronauts have collected extensive photographic data using various sensors for Earth resources experiments, documenting phenomena like droughts, typhoons, and mineral resources. 00:13:03 Skylab Commander Jerry Carr emphasizes that Skylab is applying past knowledge and expertise to establish a routine for living and working in space. 00:13:35 The data and knowledge gained from Skylab are surpassing all initial expectations, highlighting its importance for future space endeavors.
