When people talk about "a GPS," they usually mean a GPS receiver, but the Global Positioning System (GPS) is actually a constellation of many Earth-orbiting satellites (gps.gov/systems/gps/space/">31 in operational orbit and four that are classified as either "in reserve" or "unhealthy...
Electrons circle the nucleus in fixed orbits -- a simplified way to think about it is to imagine how satellites orbit the Earth. There's a huge amount of theory around electron orbitals, but to understand light there is just one key fact to understand: An electron has a natural orbit that...

As of May the 4th, 2024 (be with you), the satellite tracking website "Orbiting Now" lists 9,900 active satellites in various Earth orbits. A deeper dive how many satellites are in Space
As the name implies,satellite internetuses satellites orbiting the Earth to provide internet access, particularly in remote or rural areas where traditional wired connections are unavailable. The process begins with an ISP sending data to a satellite in geostationary orbit. The satellite then relays th...

Gyroscopes are built into compasses on ships and aircraft, the steering mechanism in torpedoes, and the guidance systems installed in ballistic missiles and orbiting satellites, among other places. Why do gyroscopes defy gravity? They may seem to defy gravity, but they don't. That effect is du...

capture a capsule dropped by a US satellite, containing film of Earth’s surface. He quotes an off-the-record comment by President Lyndon Johnson about the secret film’s value: “We were building things we didn’t need to build… Because of satellites Iknowhow many missiles the enemy has...
How many satellites does the asteroid belt have? Does Halley's Comet enter the Earth's atmosphere? What is the surface temp of Halley's Comet? How many dwarf planets are in the Kuiper belt? What is Halley's Comet nucleus? What is the size of Comet Encke? How many chemically different...
