Geostationary orbit used to be a parking lot. Some Chinese satellites are circling the lot, tailgating other cars, and pulling into spots that aren't theirs. This report explores nine years of data on ...

The OEO satellite promises a geosynchronous orbit around the equator, low latency, and a drastic cut in costs—using readily ...

It's been decades since humanity first sent a satellite into orbit, and during all this time we kind of become experts at it. What we still haven't mastered yet is extending the life of these ...

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China’s Shijian-21 ...

In a breakthrough that could redefine the strategic race for the Moon, China has successfully executed a satellite-to-satellite refueling operation in geosynchronous orbit, according to reporting from ...

SpaceX is scheduled to launch a Falcon 9 rocket from Cape Canaveral, Florida this week. The rocket will carry the EchoStar XXV satellite into geosynchronous orbit. The launch window is set for ...

A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day).

Arianespace has performed one Ariane 6 launch so far this year, carrying a set of Amazon Leo satellites into orbit in February. Cavaillolès told reporters in January the company was planning to ...

China's space program took a major stride this past week as two of its satellites seemingly docked together in what could have been the country's first high-altitude attempt at refueling a satellite ...

A team led by Peng Zhou at Fudan University has built a radio-frequency communication system from atomically thin molybdenum disulfide transistors, flown it aboard a satellite in low Earth orbit for ...
