Since satellites are high in the sky, there are a lot more customers in the line of site. Satellite television systems transmit and receive radio signals using specialized antennas called satellite dishes. The television satellites are all in geosynchronous orbit, meaning that they stay in one ...
On May 1, theSDA released its solicitation for the first 10 satellitesthat will make up its transport layer — a space-based mesh network in low-Earth orbit. When fully developed, that transport layer will provide a global network that various sensors, shooters and tactical networks will be ...
All of these satellites are sensitive at some level to space weather effects. Predictions of drag on LEO spacecraft are one of the most important. Launching a satellite with less fuel can mean a higher orbit, but unanticipated solar activity and increased drag can make that a Pyrrhic victory....
Why do we need satellites? There are various reasons why we need to send objects into space. Some are sent for exploration. They go beyond the orbit of our beloved planet and are equipped with probes and sensors to monitor and study the various parts of our solar system. Others bring us...

Most recently, aSmart Dragon-3 (SD-3) carrier rocketblasted off on Saturday, sending a group of nine satellites, including the world's first in-orbit AI commercial hypersatellite, into planned orbit. With a carrying capacity of 1.5 tonnes to the sun-synchronous orbit, the f...
But, all-electric satellites carry a trade-off. “The only disadvantage is that since the thrust of such systems is lower than chemical propulsion systems, it will take satellites up to six months longer to reach their final orbit,” says Tun. ...
