After more than a week of delays, two new NASA missions have gotten the greenlight to head to space tonight (March 8).

This diagram demonstrates the interaction ... spacecraft controllers on the ground may need to take action to stop satellites from tumbling, and orbit corrections may be needed.

The uncrewed aircraft manufacturer says it has completed two test flights of a Grey Eagle 25M controlled remotely via a ...

With the rapid increase in satellite constellations and the evolving needs of defense, commercial, and enterprise users, Orbit's OrBeam MIL ESA delivers an agile, multi-orbit solution that ...

The team carried out simulations of how carbon emissions affect the upper atmosphere and orbital dynamics, in order to estimate the "satellite carrying capacity" of low-Earth orbit. These ...

Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites more vulnerable to damage, according to new research Margherita Bassi ...

China has also recently added to its activities with a new satellite apparently set to test on-orbit servicing in GEO. “Just this past January, the Chinese put on orbit what’s known as the ...

By the year 2100, the “satellite carrying capacity” of the most popular low-orbit regions could decline by 50 to 66 percent due to the impacts of these emissions, according to the study ...

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 ...

Rocket Lab launched a high-resolution Earth-imaging satellite toward low Earth orbit this evening (Feb. 18). An Electron vehicle carrying the first "Gen-3" satellite for the geospatial ...
