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.

By the mid-1960s, communications satellites had become reliable tools. Satellites positioned in high orbits could "see" large swaths of Earth, allowing them to receive and send signals from distant places. Satellites brought radical change, filling in communication gaps and providing telephone and television connection nearly worldwide.
Corona Spy Satellite Camera in Space Race

More advanced reconnaissance satellites - still classified - have since replaced Corona. Photos taken by Corona spy satellites were returned to Earth in nose cone capsules like this one, which was recovered from orbit in May 1972 during the final Corona mission.
Applications Satellites - National Air and Space Museum

In the tense years of the Cold War, such spacecraft (known as applications satellites) evolved down two separate paths: one devoted to national security needs, the other to civilian interests. Today, hundreds of civilian and military applications satellites ring the Earth, often operating side-by-side in orbit.

Earth's natural satellite is the Moon, but many objects in our Solar System have multiple natural satellites. Humans have also created artificial satellites?human-made machines and spacecraft in orbit around our Earth or other objects in our galaxy.

From 1960 to 1972, more than 100 Corona missions took over 800,000 photographs. As cameras and imaging techniques improved, Corona and other high-resolution reconnaissance satellites provided increasingly detailed information to U.S. intelligence analysts. In this video, listen to curator James David talk about the Corona spy satellite.
Satellite, Communications, Sirius FM-4 - National Air and Space Museum

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.
What are the Main Parts of a Communications Satellite?

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 ...
Communications Satellite, Oscar I - National Air and Space Museum

Launched in December 1961, OSCAR 1 (Orbiting Satellites Carrying Amateur Radio) was the world's first non-governmental satellite. Built by a group of California based amateur radio operators for only 63 dollars, OSCAR I operated for nearly 20 days, testing radio reception from space.
TIROS Meteorological Satellite - National Air and Space Museum

By the mid 1960s, the civilian TIROS program launched a series of satellites to provide routine, daily weather observations. The program is still in operation today and, in conjunction with other weather satellites, has made space-based weather observations a commonplace of contemporary life.
