STS-41-G Patch
STS-41-G (formerly STS-17) was the 13th flight of NASA's Space Shuttle program and the sixth flight of Space Shuttle ''Challenger''. ''Challenger'' launched on October 5, 1984, and conducted the second shuttle landing at Kennedy Space Center on October 13, 1984. It was the first shuttle mission to carry a crew of seven, including the first crew with two women (Sally K. Ride and Kathryn D. Sullivan), the first American Extravehicular activity (EVA) involving a woman (Sullivan), the first Australian-born person to journey into space as well as the first astronaut with a beard ( Paul D. Scully-Power) and the first Canadian astronaut (Marc Garneau). STS-41-G was the third shuttle mission to carry an IMAX camera on board to document the flight. Launch and in-orbit footage from the mission (including Sullivan and Leestma's EVA) appeared in the 1985 IMAX movie '' The Dream is Alive''.

Space Transportation System
The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program. (NASA appropriated the name for its Space Shuttle Program, the only component of the proposal to survive Congressional funding approval). The purpose of the system was two-fold: to reduce the cost of spaceflight by replacing the current method of launching capsules on expendable rockets with reusable spacecraft; and to support ambitious follow-on programs including permanent orbiting space stations around Earth and the Moon, and a human landing mission to Mars. In February 1969, President Richard Nixon appointed a Space Task Group headed by Vice President Spiro Agnew to recommend human space projects beyond Apollo. The group responded in September with the outline of the STS, and three different program levels of effort culminating with a ...

Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

Space Shuttle Seating Plan
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 "space ...

Canadian Space Agency
The Canadian Space Agency (CSA; french: Agence spatiale canadienne, ASC) is the national space agency of Canada, established in 1990 by the ''Canadian Space Agency Act''. The president is Lisa Campbell, who took the position on September 3, 2020. The agency is responsible to the minister of innovation, science and industry. The CSA's headquarters are located at the John H. Chapman Space Centre in Longueuil, Quebec. The agency also has offices in Ottawa, Ontario, and small liaison offices in Houston; Washington, D.C.; and Paris. History The origins of the Canadian upper atmosphere and space program can be traced back to the end of the Second World War. Between 1945 and 1960, Canada undertook a number of small launcher and satellite projects under the aegis of defence research, including the development of the Black Brant rocket as well as series of advanced studies examining both orbital rendezvous and re-entry. In 1957, scientists and engineers at the Canadian Defence Research Te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IMAX
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio (approximately either 1.43:1 or 1.90:1) and steep stadium seating. Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw were the co-founders of what would be named the IMAX Corporation (founded in September 1967 as Multiscreen Corporation, Limited), and they developed the first IMAX cinema projection standards in the late 1960s and early 1970s in Canada. IMAX GT is the large format as originally conceived. It uses very large screens of and, unlike most conventional film projectors, the film runs horizontally so that the image width can be greater than the width of the film stock. It is called a 70/15 format. It is used exclusively in purpose-built theaters and dome theaters, and many installations limit themselves to a projection of high quality, short documentaries. The high costs involved in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Astronaut
The Canadian Astronaut Corps is a unit of the Canadian Space Agency (CSA) that selects, trains, and provides astronauts as crew members for U.S. and Russian space missions. The corps has four active members, able to serve on the International Space Station (ISS). History The original 6 astronauts selected in 1983 were under the auspices of the National Research Council of Canada. They were transferred to the Canadian Space Agency when it was established in 1989. Since 1984, when Marc Garneau became the first Canadian in space, nine CSA astronauts have flown on US NASA Space Shuttles and on Russian Soyuz rockets in 15 missions. In May 2009, Robert Thirsk flew to the International Space Station (ISS) for a six-month stay, thus becoming the first Canadian to stay aboard the ISS for an extended period. On December 1, 2009, after spending 188 days in space, Robert Thirsk returned to Earth aboard a Soyuz spacecraft. Canadian astronaut Chris Hadfield, the first Canadian Commander of the ...

Extravehicular Activity
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 ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-51-A
STS-51-A (formerly STS-19) was the 14th flight of NASA's Space Shuttle program, and the second flight of Space Shuttle ''Discovery''. The mission launched from Kennedy Space Center on November 8, 1984, and landed just under eight days later on November 16, 1984. STS-51-A marked the first time a shuttle deployed two communications satellites, and retrieved from orbit two other communications satellites. The Canadian Anik D2 and Syncom IV-1 satellites were both successfully deployed by the crew of ''Discovery''. Palapa B2 and Westar 6, meanwhile, had been deployed during the STS-41-B mission earlier in the year, but had been placed into improper orbits due to the malfunctioning of their kick motors; they were both safely recovered and returned to Earth during STS-51-A.

STS-41-D
STS-41-D (formerly STS-14) was the 12th flight of NASA's Space Shuttle program, and the first mission of Space Shuttle ''Discovery''. It was launched from Kennedy Space Center, Florida, on August 30, 1984, and landed at Edwards Air Force Base, California, on September 5, 1984. Three commercial communications satellites were deployed into orbit during the six-day mission, and a number of scientific experiments were conducted, including a prototype extendable solar array that would eventually form the basis of the main solar arrays on the International Space Station (ISS). The mission was delayed by more than two months from its original planned launch date, having experienced the Space Shuttle program's first launch abort at T-6 seconds on June 26, 1984. Crew Crew seat assignments Mission background The launch was originally planned for June 25, 1984, but because of a variety of technical problems, including rollback to the Vehicle Assembly Building (VAB) to replace ...
