Ottawa-Carleton Educational Space Simulation
The Ottawa-Carleton Educational Space Simulation (OCESS), unofficially known as "SpaceSim", is a student-run organization within the Ottawa-Carleton District School Board that operates primarily out of Lisgar Collegiate Institute. The chief activity of the club is to educate youth about the sciences with relation to space. Mission An important activity conducted by Spacesim is its annual 120-hour simulated space mission. This mission is conducted in a simulated spacecraft or Habitat designed and built by the organization. The current habitat was built in the 2008/2009 school year, after the Ottawa-Carleton District School Board asked OCESS to move to a different room within the same building. The previous habitat had been built in 2001. Accompanying the Habitat is an array of custom-made software written by the current Teacher Adviser of the organization, DrJames Magwood This software handles everything from environmental conditions to the navigation and piloting of the Habitat.

Airlock
An airlock is a room or compartment which permits passage between environments of differing atmospheric pressure or composition, while minimizing the changing of pressure or composition between the differing environments. An airlock consists of a chamber with two Hermetic seal, airtight doors or openings, usually arranged in series, which do not open simultaneously. Airlocks can be small-scale mechanisms, such as Fermentation lock, those used in fermenting, or larger mechanisms, which often take the form of an antechamber. An airlock may also be used underwater to allow passage between the air environment in a pressure vessel, such as a submarine, and the water environment outside. In such cases the airlock can contain either Atmosphere of Earth, air or water. This is called a floodable airlock or underwater airlock, and is used to prevent water from entering a submersible vessel or underwater habitat. Operation The procedure of entering an airlock from the external or am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravitationally bound Planetary system, system of the Sun and the objects that orbit it. It Formation and evolution of the Solar System, formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a hydrostatic equilibrium, balanced equilibrium by the thermonuclear fusion, fusion of hydrogen into helium at its stellar core, core, releasing this energy from its outer photosphere.

Ottawa-Gatineau
The National Capital Region (NCR) (, ), also known as Canada's Capital Region and Ottawa–Gatineau, is an official federal designation encompassing the Canada, Canadian capital of Ottawa, Ontario, the adjacent city of Gatineau, Quebec, and surrounding suburban and Exurb, exurban areas. Despite its designation, the NCR is not a separate political or administrative entity and falls within the provinces of Ontario and Quebec. Defined by the ''National Capital Act'' (1985), the NCR covers an area of , straddling the Ottawa River, which serves as the boundary between Ontario and Quebec. This area is smaller than the Ottawa–Gatineau Census geographic units of Canada#Census metropolitan areas, census metropolitan area (CMA), which spans . Ottawa–Gatineau is the only CMA in Canada that crosses provinces and territories of Canada, provincial boundaries. History The Algonquin people, Algonquins are indigenous to Ottawa-Gatineau. The first European settlement in the region was l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planetarium
A planetarium (: planetariums or planetaria) is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate their motion. The projection can be created in various ways, such as a star ball, slide projector, video, fulldome projector systems, and lasers. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth. Planetaria range in size from the 37 meter dome in St. Petersburg, Russia (called "Planetarium No 1") to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Planetariu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ottawa Citizen
The ''Ottawa Citizen'' is an English-language daily newspaper owned by Postmedia Network in Ottawa, Ontario, Canada. History Established as the Bytown ''Packet'' in 1845 by William Harris (journalist), William Harris, it was renamed the ''Citizen'' in 1851. The newspaper's original motto, which has recently been returned to the editorial page, was ''Fair Play and Day-Light''. The paper has been through a number of owners. In 1846, Harris sold the paper to John Bell (journalist), John Gordon Bell and Henry J. Friel. Robert Bell (1821-73), Robert Bell bought the paper in 1849, and sold it to I.B. Taylor in 1861. In 1877, Charles Herbert Mackintosh became the principal owner, and he later sold it to Robert and Lewis Shannon. In 1897, the ''Citizen'' became one of several papers owned by the Southam Newspapers, Southam family. It remained under Southam until the chain was purchased by Conrad Black's Hollinger Inc. in 1996. In 2000, the chain was sold to Canwest, Canwest Global, ...

Extra-vehicular 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. EVAs have 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. In 1984, Svetlana Savitskaya became the first woman to perform a spacewalk, conducting EVA outside the Salyut 7 space stati ...

Chemical Toilet
A chemical toilet collects human waste in a holding tank and uses chemicals to minimize odors. They do not require a connection to a water supply and are used in a wide variety of situations. These toilets are usually, but not always, self-contained and movable. A chemical toilet is structured around a relatively small tank, which requires frequent emptying. It is not connected to a hole in the ground (like a pit latrine), nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant. The enclosed portable toilets used on construction sites and at large gatherings such as music festivals are well-known types of chemical toilets. As they are usually used for short periods and because of their high prices, they are mostly rented rather than bought, often including servicing and cleaning. A simpler, unenclosed, chemical toilet may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PH Indicators
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. Hence, a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+) in the Arrhenius model. Normally, the indicator causes the color of the solution to change depending on the pH. Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor. The pH value of a neutral solution is 7.0 at 25°C ( standard laboratory conditions). Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic. Since most naturally occurring organic compounds are weak electrolytes, such as carboxylic acids and amines, pH indicators find many applications in biology and analytical chemistry. Moreover, pH indicators form one of the three main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Controller
Flight controllers are personnel who aid space flight by working in mission control centers such as NASA's Christopher C. Kraft Jr. Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in Real-time computing, real-time. Each controller is an expert in a specific area and constantly communicates with additional experts in the "back room". The flight director, who leads the flight controllers, monitors the activities of a team of flight controllers, and has overall responsibility for success and safety. NASA's flight controllers The room where the flight controllers work was called the mission operations control room (MOCR, pronounced "moh-ker"), and now is called the flight control room (FCR, pronounced "ficker"). The controllers are experts in individual systems, and make recommendations to the flight director involving their areas of responsibi ...
