Satellites - National Air and Space Museum 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 These types of satellites have fundamentally changed humanity—such as connecting us with
Cest quoi un satellite ? | Espace des sciences C'est quoi un satellite ? GRANDES QUESTIONS C'est un objet qui tourne autour d'une planète Il peut tourner autour de la Terre … ou d'une autre planète ! La Lune est le seul satellite naturel de notre planète Terre Mais par exemple, Mars en possède 2 et Jupiter plus de 60 !
Communications Satellite, Iridium - National Air and Space Museum This satellite is the heart of a space-based communications system called Iridium Conceived, designed, and built by Motorola, the Iridium system provides wireless, mobile communications through a network of 66 satellites in polar, low-Earth orbits Inaugurated in November 1998, under the auspices of Iridium LLC, this complex space system allowed callers using hand-held mobile phones and
Communications Satellite, Syncom A - National Air and Space Museum As satellite communications evolved in the first years of the space age, geostationary orbits gradually emerged as the most effective approach to satellite communications Spacecraft in this orbit matched the orbital rotation of the Earth and remained continuously over the same geographical area, making communication via satellite reliable and consistent
Communications Satellite, Echo 1 - National Air and Space Museum Launched in 1960, Echo 1 served as one of the first attempts to assess requirements and techniques for conducting communications via space The satellite was a remarkably simple device: a reflective sphere 30 meters (100 feet) in diameter Serving as a "mirror" in space, signals directed at the satellite from one location on Earth reflected back down to another location By the time Echo 2
Telstar - National Air and Space Museum Telstar, launched in 1962, was the first active communications satellite: it received microwave signals from ground stations and retransmitted them across vast distances back to Earth
Echo 1 Communications Satellite - National Air and Space Museum Launched in 1960, Echo 1 was designed to explore the new field of communications via space Its design was remarkably simple: Essentially a large balloon, measuring 30 meters (100 feet) across, the satellite provided a reflective surface in space Radio signals directed at Echo from one location on Earth "bounced" to another By the time Echo 2 was launched in 1964, other types of
Model, Communications Satellite, INTELSAT VI - National Air and Space . . . A total of six Intelsat VI satellites entered into service over the period 1989-1991 By this time the Intelsat satellites had become a crucial means for transmitting live news and television programming around the globe In a 1990 launch, an Intelsat VI satellite only managed to achieve low Earth orbit, rather that its intended geostationary orbit of 35,800 kilometers (about 22,300 miles) In
Satellite | Espace des sciences Quand nous regardons la Lune, elle nous présente toujours la même face Grâce aux sondes lunaires, on a pu avoir des images de la face cachée de notre satellite naturel Cette face est beaucoup plus cratérisée que celle visible depuis la Terre C'est comme si la Lune nous avait protégé de la chute de nombreux astéroïdes et météorites qui, sans elle, auraient normalement percuté
