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 ...

What Can You Really See From Space? - National Air and Space Museum
Most people know that satellites in orbit do useful things such as collect images of the Earth's surface. At the National Air and Space Museum I use satellite images in my job to understand changes in the Earth's land surface.
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.
Explorer - National Air and Space Museum
Explorer-1 was the United States' first successful orbiting satellite. Following the failure of Vanguard in December 1957, the JPL- ABMA group was permitted to adapt the Jupiter-C reentry test vehicle to carry an instrumented satellite into earth orbit. The resulting Explorer-1 satellite was successfully launched and placed into Earth orbit on January 31, 1958. Explorer-1, also known ...
Applications Satellites - National Air and Space Museum
In the tense years of the Cold War, applications satellites evolved down two separate paths: one devoted to national security needs, the other to civilian interests.

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 ...
What Makes a Moon a Moon? | National Air and Space Museum
A moon is a planetary body that goes around another planetary body. Usually, this is one or more moons going around a planet, but it doesn’t have to be a planet. In Star Wars, the Death Star is not a moon because it isn’t a naturally occurring satellite: the International Space Station, the Juno spacecraft orbiting Jupiter, or any of the telecommunications satellites we rely on in low ...
Corona KH-4B Camera - National Air and Space Museum
The KH-4B was the last and most advanced camera system used in Project Corona, America and the world's first photoreconnaissance satellite program. Between August 1960 and May 1972, when the program ended, 145 Corona satellites were launched and they produced over 800,000 usable images of the USSR and other nations. Film return capsules containing the exposed film separated from the spacecraft ...
