As of the beginning of 2023, nearly 15,000 satellites are orbiting our planet. With so many orbiting bodies circling the Earth, it's a miracle they don't crash into each other, right? It might seem like magic, but in reality, it's because they aren't all orbiting at the same height. Let's take a closer look at what LEO, MEO and GEO satellites are, and why more companies are investing in LEO and MEO satellites to support space exploration.
What are satellites used for? Our tech and communication relies mostly on these devices. Explore all uses of wireless communication and find out if too many manmade devices orbiting the Earth poses any dangers.
German Aerospace Center (DLR) signs €310.5 million contract with OHB Systems for Heinrich Hertz Satellite launch in 2021. Satellite to be the first "smart" satellite in orbit, offering flexibility in missions and communication services. OHB faces pressure after atomic clock failures in other launches.
The space elevator is a gigantic concept and as such it has many safety issues that would have to be resolved before construction begins. A space elevator would present a navigational hazard, both to aircraft and spacecraft.
Why non-rocket spacelaunch? Because the current chemical rockets are really expensive. In order to further explore outer space and establish a permanent human presence in space we need more cost efficient spacelaunch methods.
