... I moved office furniture! Perhaps I should have said Rocket Scientist! Meteosat Second Generation (MSG) satellites operate in geostationary orbit nearly 36,000 km over the west coast of Africa, from where they continuously scan the globe, showing...
... services. It is estimated that there are around 34,000 trackable objects - larger than 5-10 cm in low Earth orbit (LEO) and 30 cm to 1 m in geostationary orbit (GEO) - as well as several thousands to millions of non-trackable debris particles...
... that is still widely used. The effective use of the spectrum by large SC during television transmission from geostationary orbit is telling – the same frequency may be used by satellites in different positions and additionally radiate with different...
...asteroid at the L1 or L2 or L5 Lagrangian points of Earth’s orbit and tug Earth away. Sound implausible? Maybe it’s time to take ... a very, very long tether from Earth to above geostationary orbit, secured to a counterweight, it could be possible to...
... demonstrated similar capabilities. And now, a Russian Luch satellite is manoeuvring from one satellite to another in geostationary orbit. Apart from potentially hostile activities, we face a threat from the growing population of space debris. This...
... seen by radio telescopes on Earth because they are blocked by our ionosphere. If we could position a radio telescope up at geostationary orbit (GEO) or higher, well above the ionosphere, we could observe and characterise these short-lived phenomena...
