A satellite is an object that is in orbit around an object in space of a larger size. Things such as the Earth's Moon or Pluto's Charon are natural satellites. Humans have also created artificial satellites—human-made machines and spacecraft in orbit around our Earth or other objects in our galaxy.
This is a replica of Ariel-1 satellite, the world's first internationally conceived and executed satellite. The flight model was designed and built by NASA's Goddard Space Flight Center (GSFC) and carried six British experiments designed to study the ionosphere and its relationship to solar radiation, including cosmic ray, solar emission and ...
In 1958, President Dwight D. Eisenhower used SCORE—the first communication satellite—to broadcast a Christmas message: "Through this unique means I convey to you and all mankind, America's wish for peace on Earth and goodwill toward men everywhere." The SCORE (Signal Communications by Orbital Relay Equipment) satellite operated for 35 days.
The Predator can provide near real-time reconnaissance using a satellite data link system and perform attack missions as well. The Museum's Predator was one of the first three UAVs to fly operational missions over Afghanistan after the 9/11 terrorist attacks.
Last week, the Museum recognized the 50th anniversary of Telstar, the first “active” satellite (one that can receive a radio signal from a ground station and then immediately re-transmit it to another) and the first technology of any kind that enabled transatlantic television transmissions. In 1962, both accomplishments generated intense interest, excitement, and commentary.
Most communications satellites have the same basic components, pointed out in this diagram: Solar cells and batteries to power the satellite systems Antennas to receive and transmit signals Transponder to alter the frequency of incoming signals (avoiding interference with outgoing signals) and to amplify signals before transmitting them back to Earth Orientation and propulsion systems to keep ...
While commonplace today, satellite weather tracking was not possible before 1960. The first images of weather from space were taken by the TIROS I satellite on April 1, 1960. Today, different types of satellites, using a variety of tools, monitor and capture images of weather on Earth and in space.
This satellite represents the first generation of space-based, commercial radio service developed by Sirius Radio, a U.S. company (now Sirius XM Radio). Designed in 1987 and initiating service in 2001, the Sirius satellite system consisted of three satellites that provided more than 150 digital music and audio channels to North America.
Key Accomplishment(s) World's First Weather Satellite Brief Description TIROS (Television Infrared Observation Satellite) I was the world's first weather satellite. Launched in April 1960, it imaged large swaths of the Earth's surface, allowing forecasters and scientists to see large-scale weather system features for the first time.
The United States chose government direction and created two new institutions, COMSAT and INTELSAT, to develop satellite communcations, an arrangement that lasted for more than two decades. This Telstar is a backup spacecraft to Telstar 1 and 2 (launched respectively in 1962 and 1963), transferred from the National Museum of American History to ...
