Recommended: Human involvement in animal extinction
One second the Earth may be causally orbiting around the sun, functioning normally, and the next it could be sucked into a rogue black hole, without anyone even knowing until it is too late. In our small world, mankind may seem powerful and unstoppable. However, in the bigger picture, they are just another speck on some tiny planet, somewhere in the middle of the universe. The real question is, what if they weren’t just specks on one tiny planet, but were specks on two planets, Earth, and Mars? On September 28, 2015, scientists from NASA (North American Space Agency) confirmed that liquid water flows on Mars today. Although they discovered water on Mars, it is only in the form of ice and snow. While finding signs of liquid water on today’s …show more content…
The species from the Ice Age, Jurassic, Triassic and Cretaceous time periods are all examples of this. So what is stopping this cycle from repeating itself? What is stopping all of the humankind from going extinct? Is it their sheer population, or their intelligence? Neither of these could stop an asteroid from hurtling into Earth, even in this day and age. If an asteroid of 10 km or wider were to hit the Earth, like it is theorized to have 65 million years ago, all life on Earth would end. Even if some people miraculously manage to survive the impact of the asteroid, the aftermath would certainly kill the rest. The effect of an asteroid of that size hitting the Earth would be, fire storms, severe tsunamis, and a nuclear winter. This nuclear winter would be caused by the dust and debris thrown into the atmosphere, from the impact causing the sun to be blocked for decades until the dust finally settles back down. However, if humankind was also already colonized on Mars the human race would survive, and after the clouds of dust settle back down and Earth becomes safe to live on once again. The human race would send people from Mars to Earth to repopulate …show more content…
There are many reasons to it, such as its accessibility, and the most important; its habitability. Mars is one of the closest planets to Earth, only taking 18 months to reach there with the technology of this day and age. Compared to the time it takes to travel to other planets in our solar system, such as Jupiter, 18 months is a minuscule time period. The other issue is that Mars is the only other habitable planet in our Solar System, other than the planet Earth. According to Elizabeth Howell, the most Habitable Planet discovered is Kepler-186f. This planet is Earth-sized and is in the habitable zone of its host star. The downside is that Kepler-186f is located 490 million light years away from Earth. Mars is also habitable for humans. It has an atmosphere, frozen water, and has enough gravity to keep humans on the surface of Mars. Aside from the frozen water located on Mars, it was confirmed by Nasa on September 28, 2015, that liquid water flows on Mars today. Mars is the most habitable planet in this solar system, it is located not too far away from the sun, and not too close to the sun either. Mars also has enough gravity to keep us on ground. There may be other planets that are more habitable than Mars or closer than Mars, but they may be non-habitable for humans, or too far away from Earth. In short Mars is the clear
Findings on Earth and other planets suggest extraterrestrial life could live in outer space, further encouraging scientists to proceed with their research. Discovering water is a great step for finding habitable planets. According to new studies, “Mars had a shallow pool of briny water on its surface long ago, NASA said in announcing what could be the strongest evidence yet that the now-dry Red Planet was once hospitable to life. ‘If we are correct in our interpretation, this was a habitable environment,’ Mr. Squyres said. These are the kinds of environments that are very suitable for life” (Bridges). Little evidence proves beings live on Mars now, but this dried up water source provides strong proof that Mars could have inhabited life in the past. Water is a key element of survival, and can also house marine life. Marine life could have simply died out when the water dried up. If Mars was truly inhabited by extraterrestrials long ago, then scientists cannot rule out living beings on any other planet in the universe, and must continue searching. Europa, one of Jupiter’s moons houses...
“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present. Scientists continue to notice several discoveries on the planet that lead them to think there was once life on the planet. Different clues have scientists wanting to find out about even more. Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before.
"The distance between Mars and Earth varies, from as little as 34 million miles (55 million km) to as much as 249 million miles (401 million km) " (Mars Facts). Nasa, Elon Musk, and many other agencies have been and are still trying to develop technology and ways to have people in Mars by the 2030's. There are many people for and against this idea and have their own reasons why such as, people shouldn't be sent to mars because of physical and Mental health problems. Also because of the lack of resources and having too much of certain resources. It is also believed that humans already have the right technology to go to Mars even though some people think the technology humans have today still does not allows us to.
Mars is our next best hope in life on another planet. Because of science mankind can grow and harvest plants in the modified mars soil, make a thick warm atmosphere, and drink no frozen mars water. Mankind can grow and flourish more as a species with this idea of colonizing mars. With more scientific advancements we can colonize mars and we will colonize mars.
There is, however, rising speculation that Mars currently holds ice and possibly flowing water in certain areas on and under the surface. Because of the surface conditions, the water would evaporate very quickly and not be directly visible from space, along with the possible exception of the polar caps, which will be discussed later. Almost all researchers and scientists believe that there is ice on Mars, but the trick is to find it and use it to our benefit.
The End of Humanity: Could the Human Species Destroy Itself? There are lots of ways humanity could be wiped out - although I don't think any of them are particularly likely. Natural causes - An extinction-level asteroid impact would probably be sufficient, although not much else would - a disease epidemic, major climate shift, etc. would still leave many survivors to rebuild within a few hundred years. The window for such an impact is, however, extremely short, because it's extremely likely that within 300 years or so we will have the means to predict and avert all dangerous impacts.
Is there such thing as life outside of Earth? The building blocks of life are carbon, nitrogen, and oxygen. Those ingredients condense to form all living things, new stars and even new planets! So, who’s to say those ingredients didn’t form other life on other planets? Think about how vast outer space is. There are millions and millions of other planets, stars and galaxies! It’s not that far out there to think that there might be other life in space, in fact, some people even have stone hard evidence that supports the idea of “aliens”. I personally believe there is such thing as extraterrestrials, and I believe they have visited earth before. As a child, I remember my dad and I would sit around all afternoon watching alien documentaries or shows about people hunting aliens and searching for UFOs. When it comes to aliens people have so many questions; have aliens been to earth before? Are they currently living on earth? Are they controlling us? Does the government know? If so, are they hiding it from the public? There are so many questions you can ask but, in order to answer them, you have to
NASA's Curiosity rover has found water in Martian soil, but it also found toxic chlorine gas. There are promising signs of flowing water, though that's still uncertain. Even if space travelers had sufficient food, water, and heat, the confined spaces and isolation of a Mars colony would be really bad for colonists' mental health. Plus, high levels of radiation would likely make Martian humans quite sick.
Well it’s not and here are the reasons why people shouldn’t go to Mars. First of all the mission to Mars is way too unpredictable and dangerous. Before even worrying about how people can survive on Mars, the people sending them there should worry about getting them there first.
The next habitual planet closest to earth is Alpha Centauri C which is 4.25 light years away. “aa Cen, 2017” We can also get to mars faster and safer if we build and launch space-planes from the moon. If we build and launch from the moon we would be closer to mars which means we need less fuel, and that means less weight, which is good. Mars is the closets planet like Earth in our solar system. The next closest planet like earth that we know about are the 7 planets in the TRAPPIST-1 system which is 39 light years away (229 trillion miles or 369 trillion kilometers).
Water is a very important part of agriculture. The water on Mars is a little different than the water here on earth. If we tried using the polar ice caps, we would have to do many things to make it worth out time. The location of the ice caps is in an area with “permafrost.” This means that the water remains frozen unless we do something to melt it. The bad part is that we don’t know what the water is actually like. When we get the contained water free, we will then have to test it and see what is needed to make the water useful. The water underneath the soil is already free, but there are many unanswered questions about that water also.
The temperatures can also change immediately within a week. This show that the weather on Mars might not be suitable for humans. The temperature is very different compare with world average temperature is 13.9°C (57.0°F) in this century. Moreover. Another factor which may be a threat to the human settlement in space is extraterrestrial life also known as “Alien”.
How would we colonize the Mars in our generation? Mars colonization means that we should send some normal people (enough for reproduction, at least 100 people), land on Mars and live in Mars. This is a similar process with what we have done in America. Our journey to Mars is truly difficult. Until now, we have or had 12 spacecraft orbit and 12 spacecraft land on Mars, but half of our mission failed on the journey to Mars (data from NASA).
There are more than just government agencies like NASA trying to make it to Mars there are a lot more private companies like SpaceX. Space travel has a lot of timing involved because the most efficient time to launch anything to Mars only comes every twenty-six months which lands in the year 2020, which will be a big year. There will be four or more spacecrafts being sent to the red planet (Skuse, 2017). Spain and Norway will be sending MOXIE which will survey the weather and ground. China is sending a spacecraft to survey the atmosphere, soil, water and ice. SpaceX will be sending one up also but what it will survey has not yet been
Many scientists have devoted time and money in hope of finding answers. Scientists have found many places that could possibly be holding life. For fifty years, many missions have been on Mars looking for space being. When searching, water is key.
