A recent report from the US National Research Council has highlighted an ever increasing problem – space debris. Ever since humans started sending things up into orbit there has been a problem with space junk, because not everything that goes up there comes back down. While larger objects will fall out of orbit and either return to Earth or burn up in the atmosphere, smaller fragments remain in orbit. While small, these fragments could do a significant amount of damage to satellites (or worse spacecraft) and there are also old satellites and spent booster rockets that remain in orbit which could cause even more damage. Some computer models are suggesting that the level of debris has reached a tipping point where there is so much debris that it will be constantly colliding – creating yet more debris. So what is the solution? Several ideas have been proposed including a giant magnet and an umbrella shaped device to sweep up debris. Whichever solution is decided upon, something needs to be done for the sake of those onboard the International Space Station, who increasingly have to dodge the space junk that shares their orbit.Discuss

There are a few ways to create a habitable planet. We think the way Earth was created was as a bunch of rocks that were orbiting the Sun and all clumped together. Scientists think that later extra water was brought by asteroids. However as the search for extra-solar planets progresses we find more and more … More

New operating systems often look more “flash” than the previous iteration, with many an Apple/Android fan raving to their friends about the new look, but do improved aesthetics actually make the product better? According to new research by Irene Reppa of Swansea University and Siné McDougall of Bournemouth University, the answer is yes . By … More
5 February 2015 Many renewable energy sources are now working remarkably efficiently and many scientists feel that with sufficient financing, continuing research and real dedication from world leaders that these could eventually take over from fossil fuels entirely. For example, in 2010, Alec Salmond claimed that Scotland could soon be run entirely on green energy … More
