A full size model of the Earth observation satellite ERS 2 In the context of spaceflight , a satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon The first artificial satellite, Sputnik 1 , was launched by the Soviet Union in . Since then, thousands of satellites have been launched into orbit around the Earth. These originate from more than 50 countries and have used the satellite launching capabilities of ten nations. A few hundred satellites are currently operational, whereas thousands of unused satellites and satellite fragments orbit the Earth as space debris . A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Venus, Mars, Jupiter and Saturn.

Visual Satellite Observer's Home Page From left to right the above images are: A Soyuz manned capsule. Satellite captured on a long exposure photograph. The external tank caught just after separation during the STS-2 shuttle mission. If you have ever star-gazed shortly after sunset or before sunrise, you have probably noticed one or two "stars" sailing gracefully across the sky. These are Earth-orbiting satellites, visible due to the reflection of the Sun's light off their surfaces toward the observer. Hundreds of satellites are visible to the unaided eye; thousands are visible using binoculars and telescopes. Observing satellites has many enthusiasts around the world. Amateur astronomers seeking new challenges, find that spotting faint, rapidly moving satellites, such as the tiny Vanguard 1 (America's second satellite), are comparable to spotting a distant galaxy. Tracking down a newly launched spy satellite in a secret orbit, tests analytical as well as observational skill. Observing the International Space Station transit the sun, moon or one of the planets, requires planning, perseverance, and often a bit of luck. Positional observers precisely measure the time and position of satellites as they cross the sky. During the first 30 years of the space age, geophysicists used such hobbyist measurements alongside those of radars and telescopic cameras, to analyze small changes in satellite orbits - called perturbations - to reveal details of Earth's upper atmosphere and gravity field. Today, positional observers contribute to public knowledge by finding, tracking and publishing the orbits of satellites in secret orbits.

dartTag = 'homepage/home'; Satellites A satellite is defined as any object that orbits any other object. Satellites can be celestial, such as a moon orbiting a planet in the solar system , or a planet in the solar system orbiting the sun . Satellites can also be man-made. Man-made satellites are typically launched into outer space from earth to collect data, photos and other information about Earth and all the many things that exist around it. From studying outer space and Earth’s atmosphere to tracking weather patterns and acquiring intelligence, satellites illuminate us with vital information and visual imagery that can not be captured in any other manner. Stay up to date with the latest satellite system information and news. Whether you’re interested in NASA and the Mars Renaissance Orbiter, which was the most recent satellite to visit the red planet, or the on-going global race to further research and explore the moon, our diverse satellite images, articles and other news features will expose you to distant places, planets and infinite possibilities for learning more about this expansive galaxy we call home.

How Satellites Work What is a Satellite? Geostationary (GOES) Satellites What are the components of a human-made satellite? ... OSCAR Satellites These links take you to subsections of this page. You can scroll down the entire page, or jump to a topic of interest. In little more than a generation, the launching of a satellite has gone from stopping the nation's business to guaranteeing that it runs like clockwork. Today, satellites, like clocks, telephones, and computers, are commonplace tools of technology. They help us navigate, communicate, monitor the environment, and forecast weather. Appropriately, the word satellite means an "attendant." In 1957, the launching of the Russian satellite Sputnik changed the course of our nation. The United States immediately launched massive efforts to compete in a breakneck Race to the Moon. In the space of a decade, our nation of armchair explorers sat glued to their television sets while Alan Shepard went up and back in a Mercury capsule in 1961, as John Glenn circled the globe 3 times in 1962, and as Neil Armstrong set foot on the moon in 1969. That sense of discovery has muted over time as we became accustomed to the miracles of space travel. The launching of a Space Shuttle mission may not even come up in a class discussion of current events, yet satellites bring those same students the ability to watch the Olympics, the weather, and news of other events from around the world that are considered "newsworthy."

Science Home Year 9 Year 10 Elective ... MHS Home Satellites in orbit A satellite (be it man made or a natural satellite such as the moon) stays in orbit due to the gravitational field of the planet. AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0','width','600','height','400','src','flash_objects/physics/satellite','quality','high','pluginspage','http://www.macromedia.com/go/getflashplayer','movie','flash_objects/physics/satellite' ); //end AC code At any particular height, there is one speed at which a satellite can maintain a permenant orbit. As gravity pulls the satellite down, the forward speed of the satellite is unaffected. This means that the satellite travels in a curved, elliptical path and will always follow the same path around the planet. Satellites can be placed at different heights so that they circle the Earth over different time periods. A low orbit of a few hundred kilometres means that the satellite will circle the Earth in less than two hours. A satellite placed at a height of around 36,000km will take 24 hours to circle the Earth. If placed above the equator, it will maintain a geostationary orbit ; it will always look to be in the same position above the Earth.

Roadmap About Gpredict Gpredict is a real-time satellite tracking and orbit prediction application. It can track an unlimited number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view). Gpredict can also predict the time of future passes for a satellite, and provide you with detailed information about each pass. Gpredict is different from other satellite tracking programs in that it allows you to group the satellites into visualisation modules. Each of these modules can be configured independently from the others giving you unlimited flexibility concerning the look and feel of the modules. Naturally, Gpredict will also allow you to track satellites relatively to different observer locations - at the same time. Gpredict is free software licensed under the GNU General Public License . This gives you the freedom to use and modify gpredict to suit your needs. Gpredict is available as source package as well as precompiled binaries for Linux, Mac OS X, and Windows via third parties.
