For decades, humans have wanted to see more of the planet we call Mars, the red planet. There have been many successful attempts to get a glimpse of the interesting planet, and scientists are still working on a better solution to get there. The first rover to explore Mars was "Mariner 4", which arrived on November 28, 1964. It was a spacecraft designated to orbit the planet of Mars, but not to land. It lasted for about 8 months, and was not able to survive much longer than that due to the conditions on and around Mars. Rovers before have captured images and samples, but this may not be enough to give us the full image of what is really happening on the diverse planet. What is the planet of Mars really like? Is it possible for us to find out using simple technology?
Mars is the fourth planet from the sun, and has received many names in history due to its characteristics and features. Mars was known by its red color due to the iron-rich minerals inside it, developing a red surface as we know today. The ancient Romans and Greeks named the planet after their god of war, due to the red surface, symbolizing blood. However, the Egyptians named it "the red one" and the Chinese named it "the fire star". Mars was first discovered in approximately 400BC by the Babylonians, and they named it "the star of death". Back in that time, Mars was visible by the eye, simply seen as a red "dot" in the sky, and some thought it was possibly a moving star. Mars has a very interesting geology that can tell anyone a lot about the planet. The red planet has a variety of surface features that give much information about its history. Some of the signs of impact on the planet are craters from meteors, the rough surface, impact basins, the polar ice caps th...

Tracy K. Smith’s “Life on Mars” is a collection of poetry dealing mainly in the search for a sense of purpose and the nature of people. The books is something of an elegy as a whole with many poems pertaining to death and the author’s struggle with the loss of her father. The poems are at once poignant and gentle in tone and leave questions than can only be answered in multiple readings. The book is segmented in four parts that travel through different topics and types of poetry. The mood ranges from passionate accounts of Orwellian politics to soft recollections of a lovers embrace; throughout the book Smith brings in references to pop culture, science, and technology that incorporate seamlessly with her words.
To better understand the planets, we need to first have a basic understanding of our

The expedition, named after its supply ship, was a private venture, financed by public contributions augmented by a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal Geographical Society. The expedition's team of scientists carried out a comprehensive scientific programme, while other parties explored Victoria Land and the Western Mountains. An attempted landing and exploration of King Edward VII Land was unsuccessful. A journey to Cape Crozier in June and July 1911 was the first extended sledging journey in the depths of the Antarctic winter. The Terra Nova Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place
Many important themes can be drawn from reading Roving Mars that share important lessons about the scientific process. This personal account by the author, Steven Squyres, shares his story of passion toward being able to play a hand in the exploration of mars. The account shares many valuable lessons that we can learn for the scientific process and trend that appear in most scientific discovery. The greatest theme that can be gathered from Squyres story is that Science is never easy and it may come with many failures but the most important thing to do is persevere through these challenges. Another important thing to gather from the book is that not all discovery involves proving everything right or testing everything then and there to see if
In mid March of 1998, a scientific break through occurred for the engineers at NASA. The space probe that they sent to Mars came back and, for the first time, contained readable and usable photographs of the planet's landscape. Full of pride over their latest achievement, NASA posted the information on the Internet. This allowed astronomy enthusiasts, students, and other interested individuals to take a first hand look at the, never before seen, Martian Landscape. (NASA)
A English astronomer named William Herschel, had been using his 40-foot reflector telescope when he had made the discovery of Mimas on September 17, 1789. The name Mimas comes from the god (or Titan) Mimas in Greek mythology who was slain by one of the gods of Olympus in the war between the Olympians and the Titans. His son, John Herschel, suggested that the moons of Saturn be associated with Greek mythical brothers and sisters of Kronus, known to the Romans as Saturn. This tradition had begun with the publication of John Herschel's 1847 book.
'A discovery so unexpected could only have singular circumstances, for it was not due to an astronomer and the marvelous telescope…was not the work of an optician; it is Mr. Herschel, a [German] musician, to whom we owe the knowledge of this seventh principal planet.' (Hunt, 35)
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
There are many interesting facts about the planets. They are classified in two different categories, which is either a Terrestrial Planet or a Gas Giant. Take Mercury for example, it is one of the terrestrial planets in the Solar System. Also, Mercury may contain ice, it slowly rotates around the Sun so it exposes all of it sides to the Sun’s strong rays, so it’s hard to visualize whether the ice remains solid. Mars has various aspects of its own; some scientists discovered that this planet has water upon its surface. This discovery was encountered by the NASA’s spacecraft Odyssey.
Mars, the beautiful red planet, is the most similar planet to earth. The terrain in general is very close to what we are used to on earth, minus the vegetation. Earth and Mars both contain polar ice caps. Mars also has water throughout the planet, but it is mostly subsoil.
People have been venturing out into the universe for many years now. In addition to satellites, both women and men astronauts have traveled into space to collect data about the universe. The first human being, the first animal, and the first spacecraft in orbit, were all achievements of the Soviet Union.
The planet Mars is named after the Roman god of War. The Greeks originally named the planet after their god of war, Ares. The Romans then followed suit and named the planet after their own god of war, Mars, because of the blood like red color. Mars gets this color from having a surface so rich in iron. The iron minerals oxidize and that causes the surface to appear completely bright red.
For the past fifty years we have been exploring the planet Mars. We have been observing it through telescopes and by sending rovers such as Opportunity, Spirit and Curiosity. Spirit and Opportunity found minerals that can only be created in the presence of water and by using Curiosity astronomers were able to figure out that Mars once had liquid water, enough energy, and enough materials that could have allowed life to form. This research and many others have allowed us to come up with a few “indicators” of life that we could see from space. We can look at the size of the star in it’s solar system, the size of the planet, the closeness of the planet to its star, the color of the star, and the color of the planet( because certain chemicals reflect different colors) in order to find good “candidates” for life. However if we do ever find life it will most likely be tiny bacteria and not the intelligent life that our society has imagined. It has been proven that the science fiction is false and UFOs have not landed on Earth. We know this because they have never been reported by an actual astronomer and they have never left and physical evidence. However this does not mean that there are no intelligent civilizations out there or that astronomers are not searching for them. We are currently looking and
Humans can expect to face some major challenges on an expedition to Mars. It has been proven that humanity can travel in space for over two years. Cumulatively, Sergei Constantinovich Krikalev, a Russian cosmonaut, has spent over eight-hundred and three days in Earth orbit (Lyndon B. Johnson Space Center, 2005). The expedition to Mars would require the crew to endure a six month journey to the planet, a year of living on the planet, and a six months journey back to Earth. Russian cosmonaut, Valery V. Polyakoz, clocking in at four-hundred and thirty-eight days for just one stay in Earth orbit, shows humanity is capable of a twelve month round trip to Mars (Schwirtz, 2009). Earth's orbit has provided some benefits to space exploration, like the magnetic field from cosmic radiation, and the proximity to Earth if an emergency were to arise (Jones, 2009). The further humans travel away from Earth the greater the risks become. The major risks to human health on a flight to Mars, living on Mars, and returning to Earth are: radiation exposure, biological problems induced by weightlessness, spacecraft malfunctions, and psychological problems brought on by isolation.
