First, Russia has now joined the fray with the recent arrival of its own suspected inspector (or attack) satellite in GEO. Second, the US Space Force is poised to order more—perhaps many ...

Putting tiny satellites in far-off GEO orbit is a thing now, and Viasat will help build them.

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 ...

Last year, scientists drove up Mauna Loa volcano on Hawai'i, aimed a laser at a reflector positioned on Haleakala peak on Maui, and beamed rapid pulses of laser light through 150 kilometers of ...

For many college students, satellites are faint dots crossing the sky on clear nights. These objects are background details from science fiction to reality, like GPS, satellite radio, and WiFi. For ...
