Advanced Space Vision System
The Advanced Space Vision System (also known as the Space Vision System or SVS) is a computer vision system designed primarily for International Space Station (ISS) assembly. The system uses regular 2D cameras in the Space Shuttle bay, on the Canadarm, or on the ISS along with cooperative targets to calculate the 3D position of an object. Because of the small number of viewing ports on the station and on the shuttle, most of the assembly and maintenance is done using cameras, which do not give stereoscopic vision, and thus do not allow a proper evaluation of depth. In addition the difficult conditions created by the particular conditions of illumination and obscurity in space, make it much more difficult to distinguish objects, even when the assembly work can be viewed directly, without using a camera. For instance, the harsh glare of direct sunlight can blind human vision. Also, the contrasts between objects in black shadows and objects in the solar light are much greater than ...

TriDAR
TriDAR, or Triangulation and LIDAR Automated Rendezvous and Docking, is a relative navigation vision system developed by Neptec Design Group and funded by the Canadian Space Agency and NASA. It provides guidance information that can be used to guide an unmanned vehicle during rendezvous and docking operations in space. TriDAR does not rely on any reference markers positioned on the target spacecraft. Instead, TriDAR relies on a laser based 3D sensor and a thermal imager. TriDAR's proprietary software uses the geometric information contained in successive 3D images to match against the known shape of the target object and calculate its position and orientation. TriDAR made its inaugural demonstration space flight on board Space Shuttle Discovery on the STS-128 mission, launched on 28 August 2009. On STS-128, TriDAR provided astronauts with real-time guidance information during rendezvous and docking with the International Space Station (ISS). It automatically acquired and tracke ...

Space Shuttle Program
The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011. Its official name, Space Transportation System (STS), was taken from a 1969 plan for Space Transportation System, a system of reusable spacecraft of which it was the only item funded for development. It flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips. The Space Shuttle—composed of an Space Shuttle orbiter, orbiter launched with two reusable Space Shuttle Solid Rocket Booster, solid rocket boosters and a disposable Space Shuttle external tank, external fuel tank—carried up to eight astronauts and up to of Payload (air and space craft), payload into low Earth orbit (LEO). When its mission was complete, the orbiter would atmospheric reentry, reenter the Earth's atmosphere and land like a glider (aircr ...

Space Shuttle Endeavour
Space Shuttle ''Endeavour'' (Orbiter Vehicle Designation: OV-105) is a retired orbiter from NASA's Space Shuttle program and the fifth and final operational Shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, in May 2011. STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135 by the United States Congress, Space Shuttle Atlantis, ''Atlantis'' became the last shuttle to fly. The United States Congress approved the construction of ''Endeavour'' in 1987 to replace the Space Shuttle Challenger, Space Shuttle ''Challenger'', which was Space Shuttle Challenger disaster, destroyed in 1986. NASA chose, on cost grounds, to build much of ''Endeavour'' from spare parts rather than refitting the Space Shuttle Enterprise, Space Shuttle ''Enterprise'', and used structural spares built during the construction of ''Space Shuttle Discovery, Discovery'' and Space Shuttle Atlantis, ...

Spacecraft Instruments
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ( space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Imagers
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spa ...

STS 114
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 late ...

STS 118
STS-118 was a Space Shuttle mission to the International Space Station (ISS) flown by the orbiter '' Endeavour''. STS-118 lifted off on 8 August 2007 from launch pad 39A at Kennedy Space Center (KSC), Florida and landed at the Shuttle Landing Facility at KSC on 21 August 2007. This was the first flight of ''Endeavour'' since STS-113 in November 2002, which was also the last successful shuttle flight before STS-107 which culminated in the loss of '' Columbia'' when it disintegrated during reentry. STS-118 pilot Charles Hobaugh had been the entry team CAPCOM for STS-107. ''Columbia'' had originally been selected for this flight, for what would have been its 29th mission, and its first and likely only visit to the ISS, mainly due to its heavier weight. The mission is also referred to as ISS-13A.1 by the ISS program. The mission added two more components to the ISS and brought supplies for its crew. During and after the mission, the media focused heavily on a small puncture in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS 117
STS-117 ( ISS assembly flight 13A) was a Space Shuttle mission flown by Space Shuttle ''Atlantis'', launched from pad 39A of the Kennedy Space Center on 8 June 2007. ''Atlantis'' lifted off from the launch pad at 19:38 EDT. Damage from a hail storm on 26 February 2007 had previously caused the launch to be postponed from an originally-planned launch date of 15 March 2007. The launch of STS-117 marked the 250th orbital human spaceflight. ''Atlantis'' delivered to the International Space Station (ISS) the second starboard truss segment (the S3/S4 Truss) and its associated energy systems, including a set of solar arrays. During the course of the mission the crew installed the new truss segment, retracted one set of solar arrays, and unfolded the new set on the starboard side of the station. STS-117 also brought Expedition 15 crewmember Clayton Anderson to the station, and returned with ISS crewmember Sunita Williams. On 11 June 2007, NASA mission managers announced a two-day ex ...
