External Stowage Platform
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. Locations and components ESP-1 The first of the external stowage platforms, called ESP-1, was installed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grapple Fixture
Grapple fixtures are used on spacecraft or other objects to provide a secure connection for a Articulated robot, robotic arm. North America The fixtures allowed the Space Shuttle, 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. Hubble Space Telescope, HST). They currently do the same for the International Space Station's Mobile Servicing System#Canadarm2, Space Station Remote Manipulator System (SSRMS) (also known as Canadarm2) and the Kibo (ISS module)#Remote Manipulator System, 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. It ...

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] |

SpaceX CRS-15
SpaceX CRS-15, also known as SpX-15, was a Commercial Resupply Service mission to the International Space Station launched 29 June 2018 aboard a Falcon 9 rocket. The mission was contracted by NASA and flown by SpaceX. Launch In early 2015, NASA awarded a contract extension to SpaceX for three additional CRS missions ( CRS-13 to CRS-15). In June 2016, a NASA Inspector General report had this mission manifested for April 2018, but this was pushed back, first to 6 June, to 9 June, to 28 June and finally to 29 June 2018. The mission launched on 29 June 2018 at 09:42 UTC aboard a Falcon 9 rocket from Cape Canaveral Air Force Station Launch Complex 40. The SpaceX Dragon spacecraft rendezvoused with the International Space Station on 2 July 2018. It was captured by the Canadarm2 at 10:54 UTC and was berthed to the ''Harmony'' node at 13:50 UTC. On 3 August 2018, Dragon was released from ISS at 16:38 UTC and deorbited, splashing down in the Pacific Ocean appro ... [...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 ESA, European ''Columbus (ISS module), 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 December 6, 2007, but due to engine cutoff sensor (ECO) reading errors, the launch was postponed to December 9, 2007. During the second launch attempt, the sensors failed again, and the launch was halted. A tanki ... [...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 July 8, 2011, and landed on July 21, 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 January 20, 2011, program managers changed STS-335 to STS-135 on the flight manifest. This allowed for training and other mission spe ...
