Old, digitized astronomical images taken before the human spacefaring age offer a unique view of the sky devoid of known artificial satellites. In this paper, we have carried out the first optical ...

Artistic impression of European Data Relay Satellite (EDRS) system (not to scale). These satellites work in GEO and relay data to and from non-GEO satellites, spacecraft, and stations that aren’t ...

The OEO satellite promises a geosynchronous orbit around the equator, low latency, and a drastic cut in costs—using readily available technology. Thousands of satellites have been deployed during ...

The Space Force wants to cut one Lockheed Martin-built geosynchronous satellite from its Next-Generation Overhead Persistent Infrared program. (Lockheed Martin) WASHINGTON — The U.S. Space Force’s ...

(via MinutePhysics) This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

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 ...

You can spot "GEOSat' satellites in far-flung orbits… if you know exactly where and when to look. Watch the sky long enough, and you're bound to see one. Seasoned observers are familiar with seeing ...

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).

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today launched a new line of plastic-packaged radiation-hardened (rad-hard) ...

We show the candidate in SuperCosmos scans of POSS-I red (left) and POSS-II red (right) images. Transients are marked with green circles. The candidate with a measured coordinate is marked with a ...
