Orbital Boom Sensor System
The Orbiter Boom Sensor System (OBSS) was a 50-foot (15.24 m) boom carried on board NASA's Space Shuttles. The boom was grappled by the Canadarm and served as an extension of the arm, doubling its length to a combined total of 100 feet (30 m). At the far end of the boom was an instrumentation package of cameras and lasers used to scan the leading edges of the wings, the nose cap, and the crew compartment after each lift-off and before each landing. If flight engineers suspected potential damage to other areas, as evidenced in imagery captured during lift-off or the rendezvous pitch maneuver, then additional regions could be scanned. The OBSS was introduced to the shuttle fleet with STS-114, the "Return to Flight" mission executed by '' Discovery'', and was flown on every mission after that until the retirement of the Space Shuttle fleet in 2011. It was used to inspect the shuttle for damage to the heat shield, officially called the Thermal Protection System (TPS), that could jeop ...

STS-114 Robot Arm Extension
STS-114 was the first "Return to Flight" Space Shuttle mission following the Space Shuttle ''Columbia'' disaster. ''Discovery'' launched at 10:39 EDT (14:39 UTC), July 26, 2005. The launch, 907 days (approx. 29 months) after the loss of ''Columbia'', was approved despite unresolved fuel sensor anomalies in the external tank that had prevented the shuttle from launching on July 13, its originally scheduled date. The mission ended on August 9, 2005, when ''Discovery'' landed at Edwards Air Force Base in California. Poor weather over the Kennedy Space Center in Florida hampered the shuttle from using its primary landing site. Analysis of the launch footage showed debris separating from the external tank during ascent; this was of particular concern because it was the issue that had set off the ''Columbia'' disaster. As a result, NASA decided on July 27 to postpone future shuttle flights pending additional modifications to the flight hardware. Shuttle flights resumed a year la ...

Laser Camera System
Neptec Design Group is an Ottawa-based Canadian vision systems company that provides machine vision solutions for space, industrial, and military applications. Privately owned and founded in 1990, Neptec supplies operational systems to NASA's Space Shuttle and International Space Station programs as one of their prime contractors. In 2000, Neptec expanded its technology to include active 3D imaging systems and 3D processing software. This led to the development of the Laser Camera System, an operational system used by NASA to inspect a shuttle's external surfaces during flight. Neptec also used this system to develop the TriDAR, a 3D imaging and tracking system designed for automated on-orbit rendezvous, inspection, and docking. It combines the LCS with a long range LIDAR sensor into the same optical path. On July 18 2018, Neptec Design Group was purchased for $32 million (CAD) by a subsidiary of Maxar Technologies, MacDonald, Dettwiler and Associates. Laser Camera System ...

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ... [...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 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 ...

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 ...

Canadarm2
The Mobile Servicing System (MSS), is a robotic system on board the International Space Station (ISS). Launched to the ISS in 2001, it plays a key role in station assembly and maintenance; it moves equipment and supplies around the station, supports astronauts working in space, and services instruments and other payloads attached to the ISS and is used for external maintenance. Astronauts receive specialized training to enable them to perform these functions with the various systems of the MSS. The MSS is composed of three components: * the Space Station Remote Manipulator System (SSRMS), known as Canadarm2. * the Mobile Remote Servicer Base System (MBS). * the Special Purpose Dexterous Manipulator (SPDM, also known as "Dextre" or "Canada hand"). The system can move along rails on the Integrated Truss Structure on top of the US provided Mobile Transporter cart which hosts the MRS Base System. The system's control software was written in the Ada 95 programming language. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-120
STS-120 was a Space Shuttle mission to the International Space Station (ISS) that launched on 23 October 2007 from the Kennedy Space Center, Florida. The mission is also referred to as ISS-10A by the ISS program. STS-120 delivered the ''Harmony'' module and reconfigured a portion of the station in preparation for future assembly missions. STS-120 was flown by , and was the twenty-third Space Shuttle mission to the ISS. Crew Crew notes As commander of STS-120, Pamela Melroy became the second woman (after Eileen Collins) to command a Space Shuttle mission. Additionally, the Expedition 16 crew that received STS-120 was commanded by Peggy Whitson, the first female ISS commander. The flight of STS-120 thus became the first time two female mission commanders were in space at the same time. Crew prior to the Space Shuttle ''Columbia'' disaster Prior to the Space Shuttle ''Columbia'' disaster, the original crew manifest for STS-120 was: The STS-120 mission patch was des ...

Spacewalk
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes ''spacewalks'' and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ''moonwalks''). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVA has been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film cani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Dynamic Range Imager
The Laser Dynamic Range Imager (LDRI) is a LIDAR range imaging device developed by Sandia National Laboratories for the US Space Shuttle program. The sensor was developed as part of NASA's "Return to Flight" effort following the Space Shuttle Columbia disaster to provide 2-D and 3-D images of the thermal protection system on the Space Shuttle Orbiter. The LDRI generates 3-dimensional images from 2-dimensional video. Modulated laser illumination is demodulated by the receive optics, and the resulting video sequences can be processed to produce 3-d images. The modulation produces a flickering effect from frame-to-frame in the video imagery. As part of the Orbiter Boom Sensor System, the LDRI is mounted at the end of the boom on a pan-tilt unit (PTU) along with an intensified video camera (ITVC). During 2-dimensional imaging of the reinforced carbon-carbon panels on the leading edge of the shuttle's wings, the LDRI is capable of seeing damage as small as a 0.020-inch crack. Dur ...
