Space Command (TV Series)
''Space Command'' was a Canadian children's science fiction television adventure series, broadcast on CBC Television in 1953 and 1954, the first time the network aired its own dramatic series. Created by Alfred Harris, the series focused on the activities of young space lieutenant Frank Anderson (Robert Barclay) aboard the space ship XSW1, along with his crewmate Phil Mitchell ( James Doohan, best known as Scotty on ''Star Trek'') and XSW1 captain Steve Cassel (Harry Geldard). Their missions dealt with various space exploration and science subjects, including sunspots, space medicine, and the search for extraterrestrial life. The XSW1 was operated by the worldwide Space Command organization, which concerned itself with space exploration and colonization. Characters at Space Command Earth included Dr. Joseph Edmunds (Andrew Anthony), Ilene Morris (Aileen Taylor), and Dr. Fleming, ( Austin Willis). Other actors appearing on the series included Joe Austin, Cec Linder, Barry Morse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Children's Television Series
Children's television series (or children's television shows) are television programs designed for children, normally scheduled for broadcast during the morning and afternoon when children are awake. They can sometimes run during the early evening, allowing younger children to watch them after school. The purpose of these shows is mainly to entertain or educate. The children's series are in four categories: those aimed at infants and toddlers, those aimed at those aged 6 to 11 years old, those for adolescents and those aimed at all children. History Children's television is nearly as old as television itself. The BBC's ''Children's Hour'', broadcast in the UK in 1946, is generally credited with being the first TV programme specifically for children. Television for children tended to originate from similar programs on radio; the BBC's ''Children's Hour'' was launched in 1922, and BBC School Radio began broadcasting in 1924. In the US in the early 1930s, adventure serials such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Television Content Rating System
Television content rating systems are systems for Content rating, evaluating the content and reporting the suitability of television programs for Minor (law), minors. Many countries have their own television evaluation, rating system and countries' rating processes vary by local priorities. Programs are rated by the organization that manages the system, the broadcasting, broadcaster, or the content producers. A rating is usually set for each individual episode of a television series. The rating can change per episode, television network, network, rerun, and country. As such, program ratings are usually not meaningful unless when and where the rating is used is mentioned. Comparison table A comparison of current television content rating systems, showing age on the horizontal axis. Note however that the specific criteria used in assigning a classification can vary widely from one country to another. Thus a color code or age range cannot be directly compared from one country to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorite
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples " bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and impact the Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditionally been divided into three broad categories: stony meteorites that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Medicine
Space medicine is the practice of medicine on astronauts in outer space whereas astronautical hygiene is the application of science and technology to the prevention or control of exposure to the hazards that may cause astronaut ill health. Both these sciences work together to ensure that astronauts work in a safe environment. The main objective is to discover how well and for how long people can survive the extreme conditions in space, and how fast they can adapt to the Earth's environment after returning from their voyage. Medical consequences such as possible blindness and bone loss have been associated with human spaceflight. In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars. History Hubertus Strughold (1898–1987), a former Nazi physician and physiologist, was brought to the United States after World War II as part of Operation Paperclip. He first coined the term "spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid
An asteroid is a minor planet of the Solar System#Inner solar system, inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type asteroid, C-type, M-type asteroid, M-type, and S-type asteroid, S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres (dwarf planet), Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slig ...

The Globe And Mail
''The Globe and Mail'' is a Canadian newspaper printed in five cities in western and central Canada. With a weekly readership of approximately 2 million in 2015, it is Canada's most widely read newspaper on weekdays and Saturdays, although it falls slightly behind the ''Toronto Star'' in overall weekly circulation because the ''Star'' publishes a Sunday edition, whereas the ''Globe'' does not. ''The Globe and Mail'' is regarded by some as Canada's "newspaper of record". ''The Globe and Mail''s predecessors, '' The Globe'' and ''The Mail and Empire'' were both established in the 19th century. The former was established in 1844, while the latter was established in 1895 through a merger of '' The Toronto Mail'' and the ''Toronto Empire''. In 1936, ''The Globe'' and ''The Mail and Empire'' merged to form ''The Globe and Mail''. The newspaper was acquired by FP Publications in 1965, who later sold the paper to the Thomson Corporation in 1980. In 2001, the paper merged with broadc ...

Sunspot
Sunspots are phenomena on the Sun's photosphere that appear as temporary spots that are darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar cycle. Individual sunspots or groups of sunspots may last anywhere from a few days to a few months, but eventually decay. Sunspots expand and contract as they move across the surface of the Sun, with diameters ranging from to . Larger sunspots can be visible from Earth without the aid of a telescope. They may travel at relative speeds, or proper motions, of a few hundred meters per second when they first emerge. Indicating intense magnetic activity, sunspots accompany other active region phenomena such as coronal loops, prominences, and reconnection events. Most solar flares and ...

Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
