Discoveries Being Made In Space and Tests Done W5
With our goal to discover mush about space, we need new discoveries. The first discovery made was an additional ring to Saturn, largest found up to date in the galaxy. In the article Largest ring in solar system found around Saturn, it was stated that this ring expands from 3 to 20 times the radius of Saturn. It was found that space weather has been relatively calm in the past three years. In the article Phantom storms: How our weather leaks into space, "And Murtagh should know - his job is to forecast space weather, which comprises any disturbance in near-Earth space, including the upper reaches of the Earth's atmosphere where satellites roam. Many of the serious events involve disturbances in the charged portion of the atmosphere, known as the ionosphere, which stretches from 80 to 1000 kilometers above sea level. The finger of blame has always been pointed at the sun, which bombards the Earth with a stream of charged particles in the form of the solar wind. During the last three years, though, the sun's cycle of activity has hit a trough, and as Murtagh observes, space weather is temporarily calm." If space weather is to stay calm, then we can send out space crafts to discover new findings. After that, the worlds most powerful ion engine was made. In Rocket company tests world's most powerful ion engine, "Rockets that would use charged particles to propel super-fast missions to Mars are one step closer, now that a small-scale prototype has been demonstrated at full power. The ion engine may be used to maintain the orbit of the International Space Station within the next five years, and could lay the groundwork for rockets that could one day travel to Mars in about a month." Once this is done, discovering new things in space will be easier on the humans.
