Back in the man of time space travel was impossible, but know we canÕt only travel in space. We can observe in space with satellites. Read this report and discover what a satellite can do for you, your family, your friends, and more. To help you and there lifeÕs. JJJ
How many satellites are radios? According to http://www.spacetoday.org/Satellites/Hamsats/HamsatsBasics.html More than 70 Amateur Radio satellites have been launched over four decades. The number is astonishing because these sophisticated and groundbreaking spacecraft are little known outside the ham radio fraternity.
According to http://inventors.about.com/library/inventors/blsatellite.htm History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a basketball, weighed only 183 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space race.
How fast do satellites travel in space?
According to http://www.astronomycafe.net/qadir/q1780.htmlSatellites orbiting the Earth such as the Space Shuttle make one orbit every 90 minutes and cover a circumference of about 40,000 kilometers. This works out to about 445 kilometers per minute or 26,000 kilometers/hour, which is 17,000 miles per hour. Spacecraft such as Galileo, sent to Jupiter have exceeded 100,000 kilometers/hour or 64,000 miles per hour.
So remember What the first satellite was and what satellites are and remember what ones are radio Because satellites may help you when your listening to the radio, watching T.V., looking at your gps, spying, and much, much more. J
