 Introduction:
“You want to wake up in the morning and think the future is going to be great - and that's what being a spacefaring civilization is all about.” (Musk in Space X , 2017) It is about believing in the future and thinking that the future will be better than the past. There are really two fundamental paths, History is bifurcate along two directions One path is we stay on Earth forever, and then there will be some eventual extinction event, the alternative is to become a space faring civilization and a multi planet species.
In early space exploration, the scientists found that Mars is the most suitable planet to live on because it has a special nature and similar to Earth, and even though the people still wonder about the other …show more content…

Mars’s size is the half size of the Earth, (May in NASA,2017). it is very cold and the average temperature is -80 degrees Fahrenheit , its gravity one-third of the Earth which is 38 percent of that found on Earth at sea level, it has the largest volcano into the solar system some of them still younger(Davis in Solar system) his atmosphere full of Carbon dioxide (95.32%) ,Nitrogen (2.7%),Argon (1.6%) and that is mean we could grow plants on it , the length of the day is remarkably 24 hours, 37 minutes which is smaller to our day on Earth. (Smith, in phoenix mars mission ). And today there are a lot of robots that were sending by NASA to explore it and check the water source and the volcano status (May in …show more content…

this sort of rocket is consists of 40 cabins and they expect to be 3-4 people per cabin and normally there will be about a hundred people on it, it is working with four vacuum engines and the risk would be closer to zero when it will entry Mars. (Musk in Space X, 2017)
This company has intended to create moon base Alpha to refill BFR system with the fuel into the Earth’s orbit to continue to the red planet, as well as they announced a bout the two mission that will going to Mars over the next five years. The first one will land on it in 2022 with two ships to confirm water resources and identify hazard life and support infrastructure for future flight, then the next mission will be in 2024 with four ships (two cargo and two crew) to build propellant plant and self-sustaining civilization on Mars. .(SpaceX, 2017) the Earth and Mars synchronization happens roughly every 26 months so we actually have an opportunity to go there in time when Mars is particularly close to Earth. (NASA gov, 2014) and the length of the trip will be n average: 3,888 hours (162 days) which means 9 months. (Taylor in Space,

There is also ice on the moon so if we buy land on the moon then we can defrost the ice on the moon and get oxygen on the moon, too. To conclude, people of Earth should be able to own land in the gorgeous area of space instead of always living in Earth, a polluted and already discovered area. In space there are no creatures there that we will need to harm or steal the lan from, so there also

Why did Columbus travel west? Why did Alexander the Great head east? Because it is that charm, that sense of unknown, that outlook for adventure and expedition which compels humans to explore new frontiers. The ultimate identification of adventure is in living on another planet, millions of light years away from Earth; where one would look up in the night sky with the knowledge that one of those brightly shining stars is in reality the planet that you were born on. However, it is a sobering fact to realize that the unfortunate reason for the human race to abandon the mother Earth and move to another planet is due to the risks caused by our own mutilation of nature whether it is by global warming or famine or nuclear threats.

From the early ages, Space and the concept of Space Exploration has retained a notion of mystique and intrigue ever since the first astrologists gazed up at the stars. With the launch of Apollo 11, Neil Armstrong became the first person to ever step on the moon. Many years of struggle as well as many lives being lost has only led to greater discoveries but the sacrifices that were made will always be mourned and remembered. And despite the risks, the notion of space travel has led us to many different discoveries and truths about the galaxy. The aims of the space program today should be centered around obtaining the brightest of mankind, to get them involved, provide safety, and continue to fulfill the treaty which “bans the use of placing

Space is a vast world worth exploring. NASA (National Aeronautics and Space Administration) has been around for 59 years. The United States should be involved in space travel because it would improve life on Earth, there is extinction protection, and it keeps people interested in space travel. One of the common arguments against exploring space is that we should explore the rest of the Earth first. Although exploring Earth is important, exploring space has many benefits of its own such as improving life on earth with things like satellites.

Al-Qaeda v Islamic State The emergence of radical jihadist organizations has become a great threat to global security in the twenty-first century, and no organizations have been more violent or notorious than Al-Qaeda and the Islamic State. Both organizations seek to establish a global caliphate governed by their extremely strict Sharia Law, and seek to purify Islam by following their ideology of Salafism. Both groups, although they differ in practice, seek to rid Muslim lands of any Western influence, and free the muslim people from the West’s oppression, specifically targeting the United States.

On Mars, humans are exposed to radiation. On Earth, however, humans are protected by a magnetic field. The effects of exposure are severe memory loss, brain damage, and cancer. That would be terrible for scientists, because when they have to go exploring for samples scientists would have to be very cautious. Although the gravity on Mars allows humans to jump higher and run faster, scientists have observed what happens to humans in low-gravity environments, including weakened immune systems, extreme fatigue, and muscle and bone loss.

The Journey to Mars An Achievement Why should we, America, go to Mars? We should go to Mars, because the trip could be a huge achievement for America. Imagine what all could happen on Mars if we were able to take a trip there. We would be able to discover the climate, and the environment on Mars. Depending on the conditions of Mars, we could possibly adapt to the changes of the climate.

(Main Idea): In the words of Stephen Hawking “Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out. But once we spread out into space and establish independent colonies, our future should be safe.” We like it our not, the humans of the future will live in the space, and life outside earth might influence dramatically the way we look.

Alternatively, there are other dangers out there that other systems do face, such as singularities (black holes), gamma ray bursts (bursts of lethal radiation), and possibly hostile life forms (aliens!). All things considered, mankind is resilient, diligent, and with the instinct of survival, anything can be accomplished. New technologies and mapping will prevent losses to the universe. Humans need a new planet to colonize and spread out upon to better support our growing needs. According to Dr. Klein “I believe the same is true about societies, civilizations and governments.

They also believe that they will find new resources to genetically modify our society. And they just might get their wishes if people start funding for space travel. Finding cures, new resources, and studying space are only a few reasons why space travel is necessary and why people should do more to fund the cause. Cancer and Mono still haven’t found a cure but, with the help of space travel, people can explore space and find other materials to find a cure for diseases. “Medicine has been revolutionized by the space program.

The Earth is a beautiful place, there is no doubt about that. Now the future is questionable due to all the manufacturing and oil drilling we’ve done. However, not only those actions are to blame, we have all played our part. Humans have created a new world, the Anthropocene. The Anthropocene is defined as the idea that we have entered a new epoch in Earth’s geological history.
