Flight Releasable Attachment Mechanism
External stowage platforms (ESPs) are key components of the International Space Station (ISS). Each platform is made from steel and serves as an external pallet that can hold spare parts, also known as orbital replacement units (ORUs), for the space station. As a platform it is not pressurized, but does require electricity to power the heaters of some of the stored equipment. ORUs are attached to the ESP via Flight Releasable Attachment Mechanisms (FRAMs), matching witness plates that mate the ORU to the platform. While ESP-1 is unique in shape, ESP-2 and ESP-3 were based on the deployable version of the Integrated Cargo Carriers (ICC), which were designed to transport unpressurized cargo inside the Space Shuttle's cargo bay. ESP-1 was transported to the International Space Station on STS-102, ESP-2 flew on mission STS-114 'Return to Flight' and ESP-3 on mission STS-118.

Integrated Truss Structure
The Integrated Truss Structure (ITS) of the International Space Station (ISS) consists of a linear arranged sequence of connected trusses on which various unpressurized components are mounted such as logistics carriers, radiators, solar arrays, and other equipment. It supplies the ISS with a bus architecture. It is approximately 110 meters long and is made from aluminum and stainless steel. Truss components All truss components were named after their planned end-positions: Z for zenith, S for starboard and P for port, with the number indicating the sequential position. The S0 truss might be considered a misnomer, as it is mounted centrally on the zenith position of ''Destiny'' and is neither starboard nor port side. Manufacturing ISS truss segments were fabricated by Boeing in its facilities at Huntington Beach, California (formerly McDonnell Douglas), Michoud Assembly Facility in New Orleans, Louisiana, Marshall Space Flight Center in Huntsville, Alabama, and in Tulsa, O ...

Photovoltaic Radiator Grapple Fixture
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system m ...

Grapple Fixture
Grapple fixtures are used on spacecraft or other objects to provide a secure connection for a robotic arm. North America The fixtures allowed the Space Shuttle's Canadarm (also known as the Shuttle Remote Manipulator System, or SRMS) to safely grapple large objects (e.g. ISS components, or satellites e.g. HST). They currently do the same for the International Space Station's Space Station Remote Manipulator System (SSRMS) (also known as Canadarm2) and the Japanese Experiment Module Remote Manipulator System (JEMRMS). The grapple fixtures are flat in appearance, with a central grapple pin topped with a sphere which the snares in the end of the arms latch on to. They use three "ramps" that help guide the robotic arm correctly onto the grapple fixture. Development The North American grapple fixture was developed at Spar Aerospace in the 1970s. Its invention is credited to Frank Mee, who also invented the Canadarm end effector for the Space Shuttle. The Grapple Fixture design w ...

Orbital Replacement Unit
Orbital replacement units (or on-orbit replaceable unit) (ORUs) are key elements of the International Space Station that can be readily replaced when the unit either passes its design life or fails. ORUs are parts of the main systems and subsystems of the external elements of the ISS, none are intended to be installed inside the pressurised modules. Examples of ORUs are: pumps, storage tanks, controller boxes, antennas, and battery units. Such units are replaced either by astronauts during EVA or by the Dextre (SPDM) robotic arm. All are stored on the three external stowage platforms (ESPs) or the four ExPRESS Logistics Carriers (ELCs) mounted on the Integrated Truss Structure (ITS). Introduction While spare parts/ORUs were routinely brought up and down during the ISS life-time via Space Shuttle resupply missions, there was a heavy emphasis once the Station was considered complete. Several Shuttle missions were dedicated to the delivery of ORUs using support carrier structures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

STS-122
STS-122 was a NASA Space Shuttle mission to the International Space Station (ISS), flown by the . STS-122 marked the 24th shuttle mission to the ISS, and the 121st Space Shuttle flight overall. The mission was also referred to as ISS-1E by the ISS program. The primary objective of STS-122 was to deliver the European ''Columbus'' science laboratory, built by the European Space Agency (ESA), to the station. It also returned Expedition 16 Flight Engineer Daniel M. Tani to Earth. Tani was replaced on Expedition 16 by Léopold Eyharts, a French Flight Engineer representing ESA. After ''Atlantis'' landing, the orbiter was prepared for STS-125, the final servicing mission for the Hubble Space Telescope. The original target launch date for STS-122 was 6 December 2007, but due to engine cutoff sensor (ECO) reading errors, the launch was postponed to 9 December 2007. During the second launch attempt, the sensors failed again, and the launch was halted. A tanking test on 18 December 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-135
STS-135 ( ISS assembly flight ULF7) was the 135th and final mission of the American Space Shuttle program. It used the orbiter ''Atlantis'' and hardware originally processed for the STS-335 contingency mission, which was not flown. STS-135 launched on 8 July 2011, and landed on 21 July 2011, following a one-day mission extension. The four-person crew was the smallest of any shuttle mission since STS-6 in April 1983. The mission's primary cargo was the Multi-Purpose Logistics Module (MPLM) '' Raffaello'' and a Lightweight Multi-Purpose Carrier (LMC), which were delivered to the International Space Station (ISS). The flight of ''Raffaello'' marked the only time that ''Atlantis'' carried an MPLM. Although the mission was authorized, it initially had no appropriation in the NASA budget, raising questions about whether the mission would fly. On 20 January 2011, program managers changed STS-335 to STS-135 on the flight manifest. This allowed for training and other mission specific p ...

STS-133
STS-133 ( ISS assembly flight ULF5) was the 133rd mission in NASA's Space Shuttle program; during the mission, Space Shuttle ''Discovery'' docked with the International Space Station. It was ''Discovery'''s 39th and final mission. The mission launched on 24 February 2011, and landed on 9 March 2011. The crew consisted of six American astronauts, all of whom had been on prior spaceflights, headed by Commander Steven Lindsey. The crew joined the long-duration six person crew of Expedition 26, who were already aboard the space station. About a month before lift-off, one of the original crew members, Tim Kopra, was injured in a bicycle accident. He was replaced by Stephen Bowen. The mission transported several items to the space station, including the Permanent Multipurpose Module ''Leonardo'', which was left permanently docked to one of the station's ports. The shuttle also carried the third of four ExPRESS Logistics Carriers to the ISS, as well as a humanoid robot called Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
