International Space Station (ISS) crews allow scientists to study what happens to a body in long-term microgravity, which is the condition of being weightless. The ISS is the first step toward the goal of figuring out a way to have healthy human beings who are engaged in long-term space conversation. People ‘s bodies were not meant to exist in the situations and deteriorate after long space journeys as a result. The International Space Station also performs many experiments which improve the quality of life on earth and would not be possible to do on planet. For all the importance of what goes on aboard, the International Space Station and countries that cooperate to keep her orbiting have always feared that it would be unable to avoid its personal doomsday Apocalypse.
The enemy that ISS and her crew must confront daily is not the ways in which earth-based conflicts might impact in often international crew or even working to combat the negative effects of microgravity on crew members, it is the presence of space junk. Space and is comprised of the many non-working satellites, rocket bodies, and other parts from space missions, as well as smaller pieces that have broken off from larger space trash and are now floating independently. Due to the shielding which the space station and most other modern spacecraft possess., they can withstand impacts of four-tenths of an inch or less. However, this is inadequate because, according to ground-based radar and computer systems, there are approximately 700,000 pieces of debris bigger than that floating around in space.
Until now the only way for the International Space Station to avoid being damaged by these projectiles was to alter its trajectory. However, since one in 10 pieces of space junk are difficult to see, and, therefore, avoid in the problem is only going it worse as more and more objects not just into lunched into the atmosphere, researchers from the Riken Computational Astrophysics Laboratory based in Japan have created the Extreme Universe Space Observatory (EUSO), a device designed to help the orbiting complex detect dangerous debris. Currently, the EUSO is scheduled to be installed on the Japanese module on the ISS in 2017. If that goes well, the International Space Station may one day be equipped with a laser capable of destroying the 4000 tons of space junk residing in low-Earth orbit, which is about 200 – 500 miles above the planet, along with the ISS.
Therefore, International Space Station may be able to avoid a doomsday apocalypse scenario for itself and its crew by aiming this laser towards any threatening debris and vaporizing it. Researchers estimate that the later could eliminate one piece of possibly dangerous junk every five minutes or 100,000 objects every year. A system like this would make activities in space much less dangerous, according to Riken’s cHief scientist Toshikazu Ebisuzaki.
The system is still in development, although it has passed proof of concept test. Coherent Amplification Network (CAN) laser, a device now under development for use in in atom mashers. Would be what shot the space junk. The CAN creates an extremely powerful by combining a lot of small ones together. It would generate t 10,000 pulses per second with each pulse being of a one-tenth of one-billionth of a second long. The CAN would be powered by approximately 17 pounds of lithium-ion batteries. It could blast troublesome objects within a range of 60 miles.
That would keep the ISS and her crew safe from the ever present danger of space debris, the fear of which now is a regular factor in the daily life aboard. Of course, the project is still in the early planning stages and will not be ready for installation for a few more years. However, it appears that International Space Station may one day be able to defend itself from a doomsday apocalypse caused by a wayward piece of space debris.
