Today the fastest space object ever created by humanity and sent into the outer space, Helios II, was proved at merely over 157,070 miles per hour, whilst the speed of light is far beyond 4000 times faster at about 669,600,000 miles per hour (Collins, Iwasaki, Kanayama, Ohnuki, 21). Over the last 50 years a huge variety of launchers have been created, counting the U.S. Space Shuttle, one of the most capable space ships to date. Nevertheless, in spite of decades of evolvement, Earth-to-Orbit transportation is extremely expensive and suffers a disastrous failure rate of a 1-2 percent. Worse, these figures have not enhanced with time. Considering the fact that over the past 50 years spacecraft force has not augment considerably enough to create a feasible speed, it is unlikely that this generation of people will accomplish an amazing boost in speed within the predictable future. The propellants have altered, but slightly, and not enough to permit large-scale space travel.
Nevertheless, it is quite possible that humankind is on the edge of an incredible breakthrough in the propulsion science. Soon NASA and JPL will wind down the operations as the space tourism sphere is just beginning to wind up. Actually, there have already been some millionaire space tourists to fly in a spacecraft to the International Space Station and back. And over the past ten years this has just been the start (Abitzsch).
NASA is probably just several decades away from evolving an antimatter spaceship, which would cut fuel expenses to a small part of what they are nowadays. NASA researchers declared initial models for an antimatter engine, which could produce huge push with small quantities of antimatter fueling it. The quantity of antimatter required to supply the engine for a year tour to Mars could be just millionth of one gram. This means that nearly ten grams of the antiprotons would be sufficient fuel to send the manned spaceship to Mars in a month. Nowadays, it takes almost a year for an unmanned spaceship to achieve Mars. In 1996, for instance, Mars Global Surveyor took eleven months to get to Mars. Researchers are confident the speed of matter-antimatter spaceship would let human beings go where no person has gone before in outer space. It would be achievable to make tours to Jupiter and even farther.
These Mars tours will pave the path for further space travels. The space missions that will allow people to go on these long trips will be made by spacecrafts, which are on the rising edge of the technology today (Barrett). Hot plasma and cold fusion will provide the power for spacecrafts on the future ventures. Work is today being done on plasma and cold fusion energy approaches and some important breakthroughs will happen within the next ten years to push space technology further. Space tourism is a reality nowadays. Not only does this type of tourism extend the freedom to travel into space for prosperous people, it suggests a profitable market to evolve the launch vehicles required to expand existence throughout the solar system. Space tourism may resolve one very difficult trouble holding up space settlement: protected and reasonably priced transportation from the surface of our planet to Low Earth Orbit.
People used to believe nothing in the universe could travel quicker than light. This approach was believed to be appropriate till the hypothetical finding of a heavy subatomic particle that may travel beyond the speed of light, recognized as tachyons. Under this finding, many researchers aspire to be capable to travel faster-than-light. Plasma thrust, the usage of gases heated to the temperature higher than the core of the sun, expels the billion-degree gases of a back of a spaceship to create incredible push. Utilizing this technology, people can be capable to accomplish a rapidity of a quarter of million miles per hour. This progression could come within the near future, practically 50 years from now (Crouch). The Earth’s resources decrease (particularly our requirement for growing amounts of the energy), as a result, this will drive the requirement for further space travel. The requirement for security will be a motivating force as the disturbing quantity of unexpected Near Earth Objects is increasing. It may follow by destruction if these objects directly strike our planet.
Space travel may lead to a huge numbers of human beings traveling to space in the next several decades (Crouch). Space settlement has marvelous possible advantages for humanity but needs a far stronger and reasonably priced launch capability than is obtainable nowadays. Customary approaches to improving launch have failed to provide an adequately able system over few decades and demonstrate little guarantee of doing this. To manage this matter, it is highly recommended to orient launch evolvement towards the tourist market, which is vast enough to support thousands of flights in a year. Just as the computers previously cost millions of dollars and were available to the few people, space travel nowadays is the zone of the wealthy. Nevertheless, as the price of computers lessened, they have become an important part of daily life for the globe’s middle-class. Space travel promises to do something analogous for individual space flight. Just as millions of years ago life moved out of the oceans and to the land, space travel can start the growth of life throughout the solar system.
