Monday’s SpaceX launch was carrying a classified satellite to space, but the secret payload was not the cause of an unusual ...

Satellites serve many purposes while they orbit above the Earth, but as they do so, how fast do they actually move? The ...

SpaceX's mission to launch the first astronauts into polar orbit is quickly approaching.

This schematic diagram shows the quantum key distribution experiment of the Jinan-1 micro-nano satellite. (University of ...

Climate change is reshaping the environment of near-Earth space in ways that could significantly limit the number of satellites able to safely operate in low Earth orbit by the end of the century ...

Abstract: In satellite Internet of Things (IoT), the remote sensing satellites capture images and then transmit them to a ground station through low Earth orbit (LEO) communication satellites for ...

Part of the greenhouse effect that warms the air near Earth's surface also cools the upper parts of the atmosphere where space starts and satellites zip around in low orbit. The cooling also makes ...

But most satellites operate in a zone called “low Earth orbit,” between 200 and 2,000 kilometers up, and can take hundreds to thousands of years to fall. The higher, outermost reaches of Earth’s ...

Now, we have determined how many satellites will fit into low Earth orbit in 2100. Due to greenhouse gas emissions, the area of the Earth's orbit that is most popular with satellite operators will ...

Climate change is reshaping the environment of near-Earth space in ways that could significantly limit the number of satellites able to safely operate in low Earth orbit by the end of the century, a ...

An atmospheric layer of special interest is the thermosphere, where the International Space Station and most satellites orbit today. When the thermosphere contracts, the decreasing density reduces ...
