Earth; our home and sanctuary. It is the only place our human civilization has ever lived on. Every single human to have ever existed has been restricted to life on this planet. In a universe filled with wonder and unknown, we feel so alone. Space is so unimaginably big, yet we have been confined within Earth’s atmosphere since our existence began, with no knowledge of what is really out there in the great depths of space. For so long, we have felt so alone with so many questions left unanswered. Curiosity is a characteristic of the human mind that we all share, and, since the creation of technology, we have been seeking answers to our astrobiological questions. Finally, we are able to scratch the surface, thanks to our technological advancements. But everything we have done is just that; scratching the surface. We must push ourselves to conduct more research, to reach out farther than we ever have, so that we may ultimately gain not only answers to …show more content…
Hematite is a mineral, and generally forms in the presence of water. Water offers the oxygen atoms that link with iron atoms in the mineral. On Mars, it seems that groundwater carrying and transporting dissolved iron had infiltrated through the sandstone to form the mineral hematite (Nasa, ).
The weather on Mars tends to continuously alternate, and can include whirling clouds, morning and afternoon mists, gusting winds and intense dust storms, which can blow at speeds of up to 250mph (CITE). These storms can proceed for weeks at a time and conceal the widespread planet, with dust rising up to 15 miles in the atmosphere. Mars is composed of numerous rocky layers. Its dense crust is 125 miles deep. This crust shields a deeper layer of heavier rock called the mantle, which is 1,360 miles thick. Mars center core is primarily made of iron. Unlike Earth’s fluid metal core, the core of Mars is indeed
Some people call Space “The Final Frontier” but at one point all land west of the Mississippi was considered the frontier. Humans are curious people, sometimes too curious for our own good, but when we find something new we always explore and why would it be any different with space. When we explore the out reaches of space will no longer seem so small or insignificant. The idea of one day unlocking all of the Universe’s secrets, solely through our own advancements as a people, is what gives me that sense of
...; quest for new frontiers continues today as earthlings burst terrestrial bonds and begin the endless voyage beyond planet and galaxy into the illimitable dark.
The water contained under the soil has had some various effects on the Mars terrain. When the robots were on mars collecting samples, they found some rocks that looked like rocks from prehistoric life here on earth. When analyzing these samples, the scientists deemed that the water was very acidic and salty. This is similar to some of the earlier times in the Australian area.
Outer space has always intrigued the human mind. Ever since humans inhabited the Earth, they have always looked to the heavens. Ptolemy, who lived over two thousand years ago, dreamed of being with the stars. He said, “I know that I am mortal by nature, and ephemeral; but when I trace at my pleasure the windings to and fro of the heavenly bodies I no longer touch the earth with my feet: I stand in the presence of Zeus himself and take my fill of ambrosia” (Tyson). At that time, reaching the “final frontier” was not even remotely possible.
When considering this topic, one might ask themselves why explore space? We explore space to compare other planets with the earth and to study the sun, to explore the universe while finding if intelligent life exists, for satellites to improve communications, weather forecasting, navigation, resource monitoring, and “to create a focal point for a new intellectual renaissance” (Ruzic).
In 1960, John F Kennedy delivered a speech to thousands at the Democratic National Convention. This speech was called “The New Frontier” proposed many new promise and ideas to the American people. One idea John F. Kennedy supported almost 60 years ago that is still being explored today is the exploration of space and uncharted territory. Many could say that discovering new things, such uncharted territories, is thrill-seeking. Although the “thrill-seekers” want to advance our lifestyle in a positive way, have they ever thought that maybe there is a reason we haven’t in the last 60 years? The risks with exploring uncharted territory just may out rank the benefits, such as: exposing humans to harmful situation, creating issues with “civilians” in those territory, and rewrite the scientific theories of what our culture originally thought.
The layer underneath the crust is the mantle, which is made up mainly of ferro-magnesium silicates. The mantle is approximately two thousand, nine hundred kilometers thick, and is separated in to the upper and lower mantle. It is in the mantle where most of the centralized...
5. Martian Geology Investigations. Planning for the Scientific Exploration of Mars by Humans. Part 2.Joel S. Levine, Ph.D., James B. Garvin, Ph.D., James W. Head, Ph.D., Journal of Cosmology, Vol 12. 3636-3646.
Human fascination with the stars is as ancient as Babylonians and has been suggested to be older than Stonehenge. From “be fruitful and multiply” to “live long and prosper,” the instinct to protect and propagate the species has manifested in religion, art, and the imaginations of countless individuals. As human understanding of space treks out of the fantastical and into the scientific, the realities of traveling through and living in space are becoming clearer. Exploring, investigating, and living in space pose an expansive series of problems. However, the solutions to the problems faced by mankind's desire to reach beyond the horizon, through the night sky, and into the stars are solutions that will help in all areas of life on Earth.
For millennia mankind has inhabited the third planet from the sun; the planet that supports life and is know to us as Earth. Although there has been life on Earth for quite sometime, it is only in the past few centuries that man has come to learn about what makes up the interior of this planet.
“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” Neil Armstrong said this about his famous trip in which he was the first man to have stepped on the moon, being one of the few who have had this opportunity. Earth has been home to humankind since its birth. Now humanity has managed to tame Earth and the next step is to traverse into the reaches of the solar system, although Earth will always be the home to humanity but there are other possible homes for us in this galaxy through colonization. Colonizing space is the next step for humanity that will bring the race causing significant advancement benefitting civilization as a whole.
Since the beginning of time, mankind has sought after learning about and exploring the universe. This yearning drove us to achieve such great things as the journey to the moon and the discovery of water on Mars. Nowadays, several people argue as to whether or not space exploration is worth the effort. I believe that it is humanity’s instinctual nature to pursue a better understanding of ourselves, and our universe. Further understanding of our universe will lead to the discovery of new technologies and ways to secure humanity’s survivability.
Some may think exploring outer space is simply a human’s curiosity. This is true but on the contrary, people explore to learn about things they may have never known and touch on the essence of the creation of the universe. Another reason for exploring this uncharted area is the technological advancements people have made and immense amount of innovation they have achieved in this field (Wood). Lastly, scientists study the other planets just in case one day humans need to relocate after overwhelming damage has been done to Earth. Suffice to say, it is a vital part of today’s day and age to research outer space (Rothery).
“Sheltered as we are by Earth's atmosphere and magnetic field, which deflect lethal radiation from space, we are like coddled children who have never ventured into a tough neighborhood” (Folger 2). Humans have been fascinated with space since the beginning of our time. Just like children and rough neighborhoods, we have tackled obstacle over obstacle to make it home again. In the end, we have a better knowledge and strength than before. The future of space exploration can assist us in answering the everlasting question of how the universe came to be. The more we explore the infinite galaxies, the more we can scientifically discover and create new technologies as science advances. As we continue to discover, we can create new fields and occupations for aspiring young students like myself.
...e very human existence relies on the universe and the way in which it works. We should invest more money, effort, and time into the study of the cosmos to preserve the human race and prosper for years to come. The time is now to start investing in the skies above. We need to preserve our intelligence, insight, and life. The cosmos need to be considered by all humans more than ever before.
