Mars
Mars is the fourth planet from the sun and the last of the solid, non-gas planets in our solar system. Mars is the seventh largest planet in our solar system. The diameter is about 4,220 miles. The equatorial circumference is about 13,259 miles. Earth’s equatorial circumference is about 24,901 miles so Mars’ equatorial circumference is approximately 53.2% that of Earth. The radius of Mars’ core is 1,056 miles. The surface area is 55,742,106 square miles, which is about 28% that of Earth. Mars’ volume is 163,115,609,799 cubic kilometers. The mass is about 641,693,000,000,000,000,000,000 kilograms. The mean density of Mars is 3,933 kilograms/meter3. Mean density gives clues about what the planet is made up of, like how much metal it has, and whether the planet is solid or gaseous (Mars Facts).
Mars is made up of many different materials. The crust and surface is made mostly of iron – rich basaltic rock similar to Earth’s thin crust. The mantle is silicate rock and the core is probably an iron, nickel, and sulfur core. Scientists are not sure though if the core is either hot liquid or cooled metal and if there is two distinct layers like Earth’s or not. Mars’ composition is similar to Earth’s. The main gases that make up Mars’ atmosphere are Carbon Dioxide (CO2), Argon (Ar), Nitrogen (N2) Oxygen (O2), and Carbon Monoxide (CO). There is about 96% carbon dioxide, 1.93% argon, 1.89% nitrogen, 0.145% oxygen, and less than 0.01% carbon monoxide. Mars’ atmosphere also has other gases in very small amounts which are called trace gases. The atmosphere on Mars is about 100 times less dense than Earth’s atmosphere (Mars Facts).
The temperature on Mars is colder than Earth because it is farther away from the sun. Th...

...mperatures and climates on Mars, the possibility of people reaching the planet and surviving, is realistic according to scientist. Mars One, a community of scientist who believe in this reality, has already begun to collect applications for those willing to take a one-way trip to Mars. They plan to start making these trips in 2024 (Human Settlement on Mars). It may not seem realistic to be able to start human settlement on Mars in just ten years, but it is possible.

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.
“The needs of the one outweigh the needs of the many” -Captain Kirk, Star Trek. In this weeks reading of The Martian, this idea is communicated in the story that saving one person is more important than saving many people.
Mercury is in many ways similar to the Moon: its surface is heavily cratered and very old; it has no plate tectonics. On the other hand, Mercury is much denser than the Moon (5.43 gm/cm3 vs 3.34). Mercury is the second densest major body in the solar system, after Earth. Actually Earth's density is due in part to gravitational compression; if not for this, Mercury would be denser than Earth. Mercury has a total area of 75 000 000 square kilometers and is the closest planet to the sun in the solor system. This indicates that Mercury's dense iron core is relatively larger than Earth's, probably comprising the majority of the planet. Mercury therefore has only a relatively thin silicate mantle and crust.
Mars is a planet that is 35 million miles away from us, yet it is one of the closest neighbors we have. From 8 years old kids to scientists who are 80, all dreamed of being on Mars. Even if the manned Mars mission would not be a reality until late 2020s, thousands of hardworking individuals are chasing their dreams. The Martian is a science fiction novel written by Andy Weir that focuses on the survival of astronaut, Mark Watney on Mars. Watney was one of the 6 astronauts on Eris 3 program; unfortunately Watney was left stranded on Mars during an emergency evacuation.
“Life On Mars” is a collection of poems written by award-winning author Tracy K. Smith. Throughout the text, she plunges into ideas about space and the unknown as well as the physical world, while incorporating emotions derived from her father's death. Smith’s poetry can be described as abstract, intriguing, and thought-provoking. As stated in The Gray Wolf Press, the Pulitzer Prize judges explained her work as “a collection of bold, skillful poems, taking readers into the universe and moving them to an authentic mix of joy and pain" (qtd. in “Life On Mars”). Smith’s fascination with the universe has allowed for readers to become knowledgeable about the mysterious world of outer-space and connect it to life on Earth. In the poem, “My God, It’s
Jack Hodgins “By the River” is a short story that delves into the lives of an isolated woman named Crystal and her husband, Jim. An unnamed narrator explores Crystal’s life with Jim as she walks through the forest to meet Jim at the train station. Jim wanted to live isolated and independently from civilization, so he and Crystal moved into the woods and started working on a farm together. Crystal had different plans for her life, but Jim talked her out of them, and she moved onto the isolated farm with him. Things did not go as planned at the farm, leaving them unprepared for what was to come.
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.
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.
The gas giants are a collection of planets in our solar system. As can be told from their name, they are mostly composed of differing mixtures of gases and ices. The gas and ice composition in question varies among the different planets. This mix of gases gives much of the planets an extremely thick atmosphere. At the very center of a gas giant is a core of liquid heavy metals. The gas giants are also called Jovian planets, taken from the largest planet in our solar system: Jupiter. Due to the fact the the majority of a gas giant planet is gas, the planet isn’t very dense and therefore, very large as a result. In fact, all of the gas giants are vastly larger than all of the terrestrial planets. Another common factor of the gas giants are their large amount of moons. The terrestrial planet, Mars, has the largest amount of moons, 2. The amount of moons of Mars is dwarfed in comparison to Saturn’s and Jupiter’s moo...
In a recent interview with Bruce Jakosky, Ph.D., Professor of Geologic and Planetary Sciences at the University of Colorado, Linda Howe asked a series of questions pertaining to Mars and what had exactly happened to the planet. The first question was: Q.) “What might have Caused Mars to lose both its surface water and magnetic field?'; A.) “The CO2 that would have produced a greenhouse atmosphere could have been lost to space. It could have been incorporated into the ground as carbonate minerals, and once that happens, the water could have frozen out in the ground.
Pluto is located 7.5 billion kilometers from Earth and is only over 2,000 km in diameter. Pluto has been labeled both a planet and a dwarf planet over the years. As said by USA Today, “a planet is a celestial body that: is in orbit around the sun, is round or nearly round, and has "cleared the neighborhood" around its orbit, meaning it is not surrounded by objects of similar size and characteristics.” Pluto only follows two of the three rules of a planet. Pluto crosses over Neptune’s orbit and is near other dwarf planets like it. Even though it breaks one rule it was officially named a dwarf planet in “August 2006”, as stated by the Library of Congress. After this event Pluto still only has one correct classification. Pluto is a planet because
He also reasoned that organisms would use the planet's atmosphere as a medium for this cyclic exchange, just as we breathe in oxygen and expel carbon dioxide. The atmosphere of Mars, like Venus, was about 95% carbon dioxide, with some oxygen and no methane. The Earth was 77% nitrogen, 21% oxygen, and a relatively large amount of methane. Mars was chemically dead; all the reactions that were going to take place had already done so. The Earth, however, was far from chemical equilibrium.
The movements of Mars and Venus in “The Planets” by Gustav Holst are two seemingly opposite pieces, with completely different feelings, tempos, and instrumental arrangements. The characteristics of the two gods couldn’t be any more opposite, yet Holst decided to put them one after the other in his symphony. With Nietzsche's “Birth of Tragedy,” knowledge of the planet’s astrology (and possibly historical context) I will uncover how the two movements are more similar than anyone ever imagined.
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.
The moon is the only natural satellite of Earth. The moon orbits the Earth from 384,400 km and has an average speed of 3700 km per hour. It has a diameter of 3476 km, which is about ¼ that of the Earth and has a mass of 7.35e22 kg. The moon is the second brightest object in the sky after the sun.
