Download or read book Assessment of Corona Arcing Hazard for Electron Beam Welding in Space Shuttle Bay at Leo for Iswe written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-16 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test welds were made in argon over a range of pressures from 10-5 to 10-3 torr (the latter pressure an order of magnitude above pressures anticipated in the space shuttle bay during welding) with and without plasma on 304 stainless steel, 6Al-4V titanium, and 5456 aluminum in search of any possible unwanted electrical discharges. Only a faint steady glow of beam-excited atoms around the electron beam and sometimes extending out into the vacuum chamber was observed. No signs of current spiking or of any potentially dangerous electrical discharge were found. Nunes, A. C., Jr. and Russell, C. and Vaughn, J. and Stocks, C. and ODell, D. and Bhat, B.

The authors describe in detail the work carried out at the E O Paton Electric Welding Institute (the main organisation working in this field).

Download or read book The Space Shuttle Program written by Davide Sivolella and published by Springer. This book was released on 2017-06-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story of the Space Shuttle in its many different roles as orbital launch platform, orbital workshop, and science and technology laboratory. It focuses on the technology designed and developed to support the missions of the Space Shuttle program. Each mission is examined, from both the technical and managerial viewpoints. Although outwardly identical, the capabilities of the orbiters in the late years of the program were quite different from those in 1981. Sivolella traces the various improvements and modifications made to the shuttle over the years as part of each mission story. Technically accurate but with a pleasing narrative style and simple explanations of complex engineering concepts, the book provides details of many lesser known concepts, some developed but never flown, and commemorates the ingenuity of NASA and its partners in making each Space Shuttle mission push the boundaries of what we can accomplish in space.Using press kits, original papers, newspaper and magazine articles, memoirs and interviews, this book provides the most up-to-date and comprehensive account available of the shuttle’s many missions and will refocus interest on a remarkable flying machine and space program that is often pushed to the background.

Download or read book Celestial Delights written by Francis Reddy and published by Springer Science & Business Media. This book was released on 2011-11-12 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Celestial Delights is essentially a 'TV Guide' for teh sky. This will be its third edition. This title, which has aggregated sales of about 20,000 copies to date in its two previous editions and has found a niche with skygazers, is much awaited. Through extensive graphics integrated with an eight-year-long calendar of sky events, it provides a look at "don't miss" sky events, mostly for naked-eye and binocular observing. The book is organized by ease of observation - lunar phases and the brighter planets come first, while solar eclipses, the aurora, and comets come later. Celestial Delights also includes a hefty dose of sky lore, astronomical history, and clear overviews of current science. It provides a handy reference to upcoming naked-eye events, with information broken out in clear and simple diagrams and tables that are cross-referenced against a detailed almanac for each year covered. Most broad-ranging astronomy field guides focus on stars, constellations, and the deep sky, but tend to ignore planetary events, which are in by far the most widely observable aspects of the changing night sky. Celestial Delights puts a variety of information all in one place, presents it in a friendly way that does not require prior in-depth astronomical knowledge, but provides the context and historical background for understanding events that astronomical computer programs or web sites lack.

Book excerpt: NOTE; NO FURTHER DISCOUNT ON THIS PRINT PRODUCT-- OVERSTOCK SALE -- Signficantly reduced list price The technologies for the reentry and recovery from space might change over time, but the challenge remains one of the most important and vexing in the rigorous efforts to bring spacecraft and their crews and cargo home successfully. Returning to Earth after a flight into space is a fundamental challenge, and contributions from the NASA Aeronautics Research Mission Directorate in aerodynamics, thermal protection, guidance and control, stability, propulsion, and landing systems have proven critical to the success of the human space flight and other space programs. Without this base of fundamental and applied research, the capability to fly into space would not exist.

Book excerpt: Once upon a space-time vector, so it has been told, far beyond the fair Arcturian skies, in the distant galactic cloud, called by the wise, Velatropa, there was a stellar unit, Velatropa 24, which produced a planet, Velatropa 24.3 (also known as Earth). Now renown for its brilliant system of rings, trans-galactic travelers often ask: "how did Velatropa 24.3 get its rings?"
