With 27 satellites now in orbit around the Earth, Amazon joins a growing number of companies working to put more than 1,000 satellites each into space to create their own mega constellation.

Satellites launched into this kind of orbit may have additional thrusters onboard, which are fired to subtly shift their arc. This is all with the intent of matching the speed of the Earth's ...

ULA launched two prototype Kuiper satellites into orbit for months of testing in October 2023, but this mission — known as Kuiper Atlas 1, or KA-01 — marked Amazon’s first full-scale launch ...

SpaceX's Starlink constellation is over 60% of all of the active satellites in orbit, and they operate at this point many thousands of satellites in a very tight altitude regime, ...
