75-470: A composite sandwich of stainless steel and 6061-T6 aluminium alloy , and a secondary barrier of Kevlar / resin . The design is based on the existing Multi-Purpose Logistics Module , as well as the European Space Agency 's Columbus module (both of which have only one passive Common Berthing Mechanism [CBM]). There are six CBMs on Harmony : the aft CBM that connects it to Destiny

100-582: Is able to operate from a powered grapple fixture on the exterior of Harmony . Harmony is equipped with eight International Standard Payload Racks : four avionics racks and four for stowage or crew quarters. The first two were delivered on STS-126 and the second two on STS-128 . After the cancellation of the Habitation Module , Harmony was chosen to house the American Crew Quarters. In an agreement between NASA and

125-589: Is passive; the rest are active. Harmony is managed by NASA's Marshall Space Flight Center in Huntsville, Alabama . Its deployment expanded the Space Station, allowing it to grow from the size of a three-bedroom house, to the space equivalent of a typical five-bedroom house, once the Japanese Kibō and European Columbus laboratories are attached. The Space Station robotic arm, Canadarm2 ,

150-542: Is the "utility hub" of the International Space Station . It connects the laboratory modules of the United States , Europe and Japan , as well as providing electrical power and electronic data. Sleeping cabins for four of the crew are housed here. Harmony was successfully launched into space aboard Space Shuttle flight STS-120 on 23 October 2007. After temporarily being attached to

175-662: The CRS-9 mission. This adapter was used for the first time for the automatic docking of the Crew Dragon spacecraft during its uncrewed test mission on 3 March 2019. On 26 March 2017, PMA-3 was robotically removed from the Tranquility module and attached to the zenith port of the Harmony module after being prepared during a successful spacewalk on 24 March 2017. A second spacewalk was conducted on 30 March 2017 to finalize

200-749: The European Space Agency , the company Thales Alenia Space , built Harmony at its facility in Turin , Italy . Harmony arrived on 1 June 2003 at the Kennedy Space Center in Florida after its flight in an Airbus Beluga oversize cargo vehicle. Following post transportation inspection, the Italian Space Agency (ASI) formally handed over Harmony to the European Space Agency (ESA). From there, ESA formally transferred ownership of Harmony to NASA on 18 June 2003, taking place in

225-759: The Multi-Purpose Logistics Modules (MPLMs) to the station, the MPLM would be temporarily berthed to the nadir mechanism of Harmony . The Japanese H-II Transfer Vehicle and the American Commercial Resupply Service (COTS) vehicles, Dragon and Cygnus , are temporarily berthed to either the nadir or zenith mechanism. In August 2016, the forward docking port was equipped with the International Docking Adapter (IDA) delivered with

250-623: The STS-120 , as the primary component of assembly mission ISS-10A . On 26 October 2007, the station's Space Station Remote Manipulator System (SSRMS) removed Harmony from the shuttle cargo bay and temporarily mated it to the port side of Unity and, on 27 October 2007, the crew entered in Harmony . After the Space Shuttle departed, Harmony was relocated to the forward dock of the Destiny laboratory. It required three EVAs by

275-679: The Space Station Processing Facility (SSPF) of the Kennedy Space Center. The handover of Harmony completed a major element of the barter agreement, between ESA and NASA, that was signed in Turin, Italy on 8 October 1997. Paolo Nespoli , an ESA astronaut born in Milan , Italy, accompanied the Harmony module aboard STS-120 as a mission specialist. Harmony was launched on 23 October 2007 aboard of

300-535: The zenith hatch of Harmony . During STS-124 , a Space Shuttle mission flown by Space Shuttle Discovery , the Pressurized Module of Kibō was added to the port side of Harmony and the ELM-PS was moved, leaving the zenith hatch empty. The zenith hatch was originally intended to be the permanent docking connector for the now canceled Centrifuge Accommodations Module (CAM). When the Space Shuttle flew

325-550: The 1960s. Since 2000, however, epoxy and polyurethane resins are used in interiors as well, mainly in Western Europe. Synthetic casting "resin" for embedding display objects in Plexiglas/Lucite ( PMMA ) is simply methyl methacrylate liquid, into which a polymerization catalyst is added and mixed, causing it to "set" (polymerize). The polymerization creates a block of PMMA plastic ("acrylic glass") which holds

350-533: The Kennedy Space Center (KSC). Since the Space Shuttle program was retired, had a decision to build and launch Node 4 been taken, it would have been launched by an Atlas V or Delta IV rocket. In December 2011 Boeing proposed using Node 4 as the core of an Exploration Gateway Platform to be constructed at the ISS and relocated via space tug to an Earth-Moon Lagrange point (EML-1 or 2). The purpose of

375-978: The PMA-3 cable connections on Harmony . PMA-3 is linked to the International Docking Adapter -3 adapter, delivered on the SpaceX CRS-18 mission in July 2019. IDA-3 was fully linked to PMA-3 during an EVA on 21 August 2019. Synthetic resin Synthetic resins are industrially produced resins , typically viscous substances that convert into rigid polymers by the process of curing . In order to undergo curing, resins typically contain reactive end groups, such as acrylates or epoxides . Some synthetic resins have properties similar to natural plant resins , but many do not. Synthetic resins are of several classes. Some are manufactured by esterification of organic compounds . Some are thermosetting plastics in which

400-562: The World Group Home School, Monona, Wisconsin. Harmony is the second of three node modules on the United States Orbital Segment (USOS). It is composed of a cylindrical, 5.1 cm (2.0 in) thick 2219-T851 aluminium alloy pressure shell with two endcones and is thermally insulated by a goldised Kapton blanket . It is protected from micrometeoroids by 98 panels, each made from

425-725: The display object inside a transparent block. Another synthetic polymer, sometimes called by the same general category, is acetal resin . By contrast with the other synthetics, however, it has a simple chain structure with the repeat unit of form −[CH 2 O]−. Ion-exchange resins are used in water purification and catalysis of organic reactions . (See also AT-10 resin , melamine resin .) Certain ion-exchange resins are also used pharmaceutically as bile acid sequestrants , mainly as hypolipidemic agents , although they may be used for purposes other than lowering cholesterol . Solvent impregnated resins (SIRs) are porous resin particles which contain an additional liquid extractant inside

450-508: The forward end of Destiny on 14 November 2007. All the following Space Shuttle missions would dock at this location. On 11 February 2008, ESA's Columbus laboratory was attached to the starboard hatch of the Harmony module during space shuttle mission STS-122 . On 14 March 2008, the Experiment Logistics Module Pressurized Section (ELM-PS) of Kibō was attached to its interim location:

475-665: The platform would be to support lunar landing missions with a reusable lunar lander after the first two SLS flights. It would also satisfy the need for a L1 propellant depot for lunar missions. Other hardware would include an airlock, an 'international module', and a MPLM based habitat module. In June 2020 the Node STA was moved from the Space Station Processing Facility to the Shuttle Landing Facility to make room for commercial partners. Harmony (ISS module) Harmony , also known as Node 2 ,

500-631: The porous matrix. The contained extractant is supposed to enhance the capacity of the resin particles. A large category of resins, which constitutes 75% of resins used, is that of the unsaturated polyester resins . The production of PVC entails the production of "vinyl chloride resins", which differ in the degree of polymerization. Silicone resins are silicone -based polymers that exhibit various useful properties like weatherability (durability), dielectricity , water repellency, thermal stability, and chemical inertness . Health hazards potentially associated with synthetic resins are typically less of

525-508: The port side of the Unity module , it was moved to its permanent location on the forward end of the Destiny module on 14 November 2007. Harmony added 70 m (2,500 cu ft) to the station's living volume, an increase of almost 20%, from 420 m (15,000 cu ft) to 490 m (17,000 cu ft). Its successful installation meant that from NASA 's perspective,

550-492: The resulting poly(methyl methacrylate) (PMMA) is often renamed "acrylic glass" or "acrylic". (This is the same material called Plexiglas and Lucite). The classic variety is epoxy resin , manufactured through polymerization -polyaddition or polycondensation reactions, used as a thermoset polymer for adhesives and composites . Epoxy resin is two times stronger than concrete, seamless, and waterproof. Accordingly, it has been mainly in use for industrial flooring purposes since

575-584: The station crew to complete the installation. Harmony was the first permanent living space enlargement to the ISS after the Pirs docking compartment was added in 2001. The Expedition 16 crew moved the Pressurized Mating Adapter (PMA-2) on 12 November 2007 from Destiny to the forward berth of Harmony . The combined PMA-2/ Harmony unit was subsequently berthed to its final destination at

600-464: The station was considered to be "U.S. Core Complete". The unit formerly known as Node 2 was renamed Harmony in March 2004. The name was chosen in a competition where more than 2,200 students from 32 states participated. The Node 2 Challenge required students to learn about the space station, build a scale model, and write an essay explaining their proposed name for the module, which will serve as

625-460: The term "resin" is loosely applied to the reactant(s), the product, or both. "Resin" may be applied to one of two monomers in a copolymer , the other being called a "hardener", as in epoxy resins . For thermosetting plastics that require only one monomer, the monomer compound is the "resin". For example, liquid methyl methacrylate is often called the "resin" or "casting resin" while in the liquid state, before it polymerizes and "sets". After setting,
