The Clarke Exobelt is the name that Dr Hector Socas-Navarro has given to perhaps the largest structure humans have built. A collection of satellites in earth orbit (geosynchronous) 36,000 km radius. All circling the earth at the same speed in the same direction. The density of this orbit has been increasing since the 1960s but is not yet sufficient…

In his 1979 novel, Fountains of Paradise, Arthur C Clarke imagines a cable stretching from the Earth's equator to Geosynchronous orbit. He called it a "space elevator" and imagined it would be constructed from continuous pseudo-one-dimensional diamond crystals. Bangalore based NoPo Technologies is now commercially producing Carbon Nanotubes. Could …

Dr Brian WeedenSpace, as the author Douglas Adams said "is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is". After 6 decades of launching spacecraft, some orbits are now congested with space debris from collisions and poor end-of-life mission management. This has now become a serious hazard and even a danger to…
