The pass predictions generates, among other things, the time window, minimum elevation and the apparent brightness of the object in the sky. Satellite Tracking provides detailed real-time and pass predictions for Earth orbiting satellites. See A Satellite Tonight shows you where to look with Google Street View.
An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. The optical, infrared and radio windows comprise the three main atmospheric windows. [2] The windows provide direct channels for Earth's surface to receive electromagnetic energy from the Sun, and for thermal radiation from the ...
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator ). [1]
Visible pass of the International Space Station and Space Shuttle Atlantis over Tampa, Florida, on mission STS-132, May 18, 2010 (five-minute exposure). An orbital pass (or simply pass) is the period in which a spacecraft is above the local horizon, and thus available for line-of-sight communication with a given ground station, receiver, or relay satellite, or for visual sighting.
A geostationary satellite is in orbit around the Earth at an altitude where it orbits at the same rate as the Earth turns. An observer at any place where the satellite is visible will always see it in exactly the same spot in the sky, unlike stars and planets that move continuously. Geostationary satellites appear to be fixed over one spot ...
Satellite flare. Top: a simulated animation of a typical Iridium flare. Bottom: Both images show a flare of an Iridium satellite. Comet Holmes can be seen in the right image, slightly above the tree branch. Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".
Meteoroid. A meteoroid shown entering the atmosphere, causing a visible meteor and hitting the Earth's surface, becoming a meteorite. A meteoroid ( / ˈmiːtiərɔɪd / MEE-tee-ə-royd) [1] is a small rocky or metallic body in outer space . Meteoroids are distinguished as objects significantly smaller than asteroids, ranging in size from grains ...
Earth's shadow (or Earth shadow) is the shadow that Earth itself casts through its atmosphere and into outer space, toward the antisolar point. During the twilight period (both early dusk and late dawn ), the shadow's visible fringe – sometimes called the dark segment or twilight wedge [1] – appears as a dark and diffuse band just above the ...
