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.

Communications Satellites - National Air and Space Museum

Communications Satellites Help Connect Us To Each Other. With the invention of things like airplanes and jet engines, our understanding of the planet shifted: Earth was becoming one connected planet?one global neighborhood. Communications satellites played a major role in this shift. Connecting with satellites

Applications Satellites - National Air and Space Museum
21 Nov 2024 at 8:14pm
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.

Military Reconnaissance | National Air and Space Museum

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.

Applications Technology Satellite, ATS-1 - National Air and Space Museum

Launched in 1966, Applications Technology Satellite 1 (ATS 1) was the first in a series of six satellites sponsored by NASA to test out new technologies in space communications and, to a lesser extent, in meteorology and understanding the space environment.

Dove Satellite | National Air and Space Museum

In the 2010s, the use of "nanosatellites" greatly expanded, especially for use in Earth remote sensing. The Dove satellite is a prime example. It uses three standard (10 cm square) building blocks.

What Can You Really See From Space?
19 Nov 2024 at 11:27am
A few non-military satellites can see objects down to about half the size of a car. Some military satellites can still see even smaller things. But that does not tell us the whole story. For most applications we need to see larger areas, which requires other satellites that observe at a different scale.

Satellite, Communications, Sirius FM-4 - National Air and Space Museum
9 Aug 2020 at 8:42am
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.

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.

Three Ways Satellites Help Us Understand Our Environment
22 Nov 2024 at 1:08am
Global Positioning System, or GPS as it is commonly known, is another way satellites help us monitor our evolving Earth?particularly when it comes to wildlife conservation. Monitoring devices equipped with GPS allow scientists to track the movement and migration of sharks, birds, elephants, and other animals.
