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 !
Learn about how a communications satellite works and how it helps us to connect to each other around the world.
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 ...
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.
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 ...
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 ...

From the ozone to underwater life, satellites help us understand our environment. In some cases, satellites enable us to take steps to protect it.

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 ...

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.
The bullet-shaped satellite payload, about 6.5 inches in diameter and 3 feet long, carried three micrometeorite detectors (a microphone, a wire grid, and metallic film), temperature sensors, …
