Manufacturing Of The International Space Station
The project to create the International Space Station required the utilization and/or construction of new and existing manufacturing facilities around the world, mostly in the United States and Europe. The agencies overseeing the manufacturing involved NASA, Roscosmos, the European Space Agency, JAXA, and the Canadian Space Agency. Hundreds of contractors working for the five space agencies were assigned the task of fabricating the modules, trusses, experiments and other hardware elements for the station. The fact that the project involved the co-operation of sixteen countries working together created engineering challenges that had to be overcome: most notably the differences in language, culture and politics, but also engineering processes, management, measuring standards and communication; to ensure that all elements connect together and function according to plan. The ISS agreement program also called for the station components to be made highly durable and versatile — as it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPLM Inside The SSPF
A Multi-Purpose Logistics Module (MPLM) is a large pressurized container that was used on Space Shuttle missions to transfer cargo to and from the International Space Station (ISS). Two MPLMs made a dozen trips in the Shuttle cargo bay and initially berthed to the ''Unity'' module and later the '' Harmony'' module on the ISS. From there, supplies were offloaded, and finished experiments and waste were reloaded. The MPLM was then reberthed in the Shuttle for return to Earth. Three modules were built by the Italian Space Agency (ASI): ''Leonardo'', ''Raffaello'', and ''Donatello''. The ''Leonardo'' module was modified in 2010 to turn it into the Permanent Multipurpose Module (PMM) and was permanently attached to the ISS during the STS-133 mission in March 2011. In July 2011, the ''Raffaello'' module was the primary payload on the final Space Shuttle mission. It returned with the Shuttle and was stored at the Kennedy Space Center. The ''Donatello'' module never launched. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

Hot Rolling
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Space Flight Center

Pressurized Mating Adapter
The Pressurized Mating Adapter (PMA) is a class of spacecraft adapters that convert the Common Berthing Mechanism (CBM) used on the US Orbital Segment to APAS-95 docking ports. There are three PMAs located on the International Space Station (ISS); the first two were launched with the ''Unity'' connecting module in 1998 aboard STS-88, and the third was launched in 2000 aboard STS-92. All three of the PMAs are now used to permanently connect parts of the ISS, so they are no longer available as docking ports for visiting spacecraft. Design/History Its origins lie in designs for the Pressurized Docking Mast, consisting of an off-axis frustoconical docking tunnel contained within a framework and a retractable coupling mechanism, later part of the Pressurized Berthing Adapter assembly that appeared in designs for Space Station Freedom 1987, and the reduced design referred to as 'Fred' 1991. After 1992-93 and the Russian integration into the International Space Station Alpha p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unity (ISS Module)
upright=1.0, The ''Unity'' module as seen in May 2011 The ''Unity'' connecting module, also known as Node 1, is the first U.S.-built component of the International Space Station (ISS). It connects the Russian and United States segments of the station, and is where crew eat meals together. The module is cylindrical in shape, with six berthing locations ( forward, aft, port, starboard, zenith, and nadir) facilitating connections to other modules. ''Unity'' measures in diameter, is long, made of steel, and was built for NASA by Boeing in a manufacturing facility at the Marshall Space Flight Center in Huntsville, Alabama. ''Unity'' is the first of the three connecting modules; the other two are ''Harmony'' and ''Tranquility''. Launch and initial berthing ''Unity'' (with its two attached PMAs) was carried into orbit as the primary cargo of the Space Shuttle ''Endeavour'' (OV 105) on STS-88, the first Space Shuttle mission dedicated to assembly of the station.

Electroforming
Electroforming is a metal forming process in which parts are fabricated through electrodeposition on a model, known in the industry as a mandrel. Conductive (metallic) mandrels are treated to create a mechanical parting layer, or are chemically passivated to limit electroform adhesion to the mandrel and thereby allow its subsequent separation. Non-conductive (glass, silicon, plastic) mandrels require the deposition of a conductive layer prior to electrodeposition. Such layers can be deposited chemically, or using vacuum deposition techniques (e.g., gold sputtering). The outer surface of the mandrel forms the inner surface of the form. The process involves passing direct current through an electrolyte containing salts of the metal being electroformed. The anode is the solid metal being electroformed, and the cathode is the mandrel, onto which the electroform gets plated (deposited). The process continues until the required electroform thickness is achieved. The mandrel is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
