The Differences Between Mars And Earth

The planet Mars is a red plant that is found in the Solar System in the Milky Way Galaxy one planets farther from the sun than Earth. The planet Mars has a very thin atmosphere full of primarily carbon dioxide. The surface of Mars is very dusty and rocky because of volcanoes. The geology of Mars is different from Earth in many ways including the amount of volcanoes, mountains, valleys, and internal makeup.

Mars is a very cooled planet, the average temperature on mars is at least minus 80 degrees, that’s way below freezing. Mars surface is very rocky with canyons, volcanos, dry lake beds and also craters all over mars. Red dust mostly covers most of mars surface. Mars is about one third of the gravity of earths atmosphere. If someone were to go to mars and they weighed at least 100 pounds they would weigh only about 37 pounds because of the reduced gravity. Mars atmosphere contains 95 percent more of carbon dioxide and less then 1 percent oxygen.

In addition, the crust of Mars contains more volatile elements such as sulfur and chlorine than Earth.

20. Although it is much colder on Mars than on Earth, the similar tilt of Earth’s and Mars’ axes means they have similar seasons. Like Earth's, Mars’ north and south polar caps shrink in the summer and grow in the winter. In addition, a day on Mars is 24 hours 37 minutes—nearly the same as Earth’s. No other planet shares such similar characteristics with Earth.e 21. Mars’ seasons are twice as long as those on Earth because it takes Mars 687 days to orbit the sun, twice as long as Earth’s 365-day journey.a 22. With no large moon like Earth’s to stabilize it, Mars periodically tilts much more toward the sun, creating warmer summers on Mars than it otherwise would have.d 23. The Earth’s moon is 240,000 miles away. Earth’s next closest neighbor is Venus, which comes as near as 24 million miles. After the moon and Venus, Mars is our next closest neighbor at 34 million miles away—though when Mars and Earth are at the opposite sides of their orbits around the sun, they are separated by 249 million miles.e 24. Mars is home to Hellas, a vast and featureless plain that covers 1300 miles (the size of the Caribbean Sea). It was created by asteroids crashing into the planet’s surface of Mars

To compare, all three planets have secondary atmospheres that were produced by volcanoes. To contrast, Venus is too close to the Sun, and was too warm for liquid water to form and without liquid water; the CO2 could not settle out of the atmosphere and dissolve into the oceans. This caused Venus to suffer from runaway greenhouse effect and became hot with an extremely dense and vastly insulated atmosphere. Along with this, UV sunlight destroyed the H2O in the atmosphere. On the other hand, Earth had enough distance from the Sun for liquid water to form and precipitate out into the ocean while the CO2 in the atmosphere dissolved into the oceans and was removed from the atmosphere. The trace amounts of H2O and CO2 in the atmosphere create an insulating layer which is enough to keep the Earth at a mild temperature. Out of the three planets, Mars is the farthest from the Sun. It is possible that Mars had liquid water earlier in its history. The CO2 dissolved into water; however, Mars has less mass than Venus or the Earth. Because of Mars’ smaller mass, it has less tectonic activity and Volcanism stopped early in its formation. This did not allow the atmosphere to be renewed from CO2 or H2O

How similar or different are Mars and Earth’s atmosphere? To start, Earth is mainly composed of nitrogen (78%), oxygen (21%) and argon (1%). Secondary compositions include the following: carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide and ammonia (universetoday.com). On the other hand, the following is the composition of Mars atmosphere: Carbon dioxide (95.32%), Nitrogen (2.7%), Argon (1.6%), Oxygen (0.13%) and carbon monoxide (0.08%) (space.com). The atmosphere of Mars is cold and thin, making life exist difficult. To elaborate, liquid water currently can’t exist on any manner of surface on Mars (space.com). To continue, dust storms add to the pain of the thin atmosphere and make life even more difficult to not exist. These dust storms can completely cover the entire planet for whole months at a time (space.com). On the other side of the spectrum, it can even snow on Mars - making the north and south

A number of things have been attributed to the red planet in contemporary times, much of it research-based, some cartoon-based. One’s childhood could have been filled with various science fiction novels about humanity colonizing the red planet or watching Bugs Bunny outsmart the Martian and his dog.

I don't think men are from Mars. I think they're from Whoville, where every year they align with the Grinch and band together to ruin Christmas. Each holiday, after thoughtfully deciding on, shopping for, and wrapping the perfect presents for my boyfriend, I can't wait to see what he picked out for me. I breathlessly anticipate tearing open the perfect romantic/sentimental gift, and every year I'm sorely disappointed.

Mars has an atmosphere made of carbon dioxide, nitrogen, and argon. It is similar in composition to Venus' atmosphere, but it does

For whatever reason, the planet Mars has always been synonymous with alien life in popular culture. This makes it very interesting to study. Recent studies have taught us a great deal about Mars’ surface, water content and geography as well as suggesting that it may have been capable of supporting life in the past. Further study of Mars’ ice caps, various impact craters and other sources has helped scientists glean information of the planet’s history and the wealth of information that can be gained from its study. Of course, the most popular topic about Mars is its present habitability and presence of life, both of which are still very possible. Mars will be an excellent planet to analyze due to its proximity to earth and its ability to potentially sustain life.

After the Earth, Mars is the most habitable planet in our solar system. Its soil contains water and when compared to our neighbor planets, Mars isn’t too cold or too hot. There is enough sunlight to use solar panels and its gravity is 38% that of our Earth’s, which is believed by many to be sufficient for the human body to adapt to in a healthy fashion. It has an atmosphere, albeit a thin one that offers protection from cosmic and sun’s radiation. Another important point is also the day and night rhythm, which is very similar, that of Earth: a Mars day is 24hours, 39 minutes and 35 seconds. According to the data gasses like carbon dioxide and nitrogen are found in the atmosphere of Mars which can be used to grow plants through hydroponics.

Mars is of course known as the “Red Planet” as the name implies, it’s red. Many people (including myself) are tricked to believe that Mars is hot, but it’s not. The surface of Mars is pretty rocky and barren. However, Mars also has Avalanches that turn up the soil, along with areas that show a possible brine, or watery area.

It is made up largely of Carbon dioxide (95.32%), along with Nitrogen (2.7%), Argon (1.6%), and Oxygen (0.13%). The biggest issue caused by a significantly thinner atmosphere synergized with not having a global magnetic field is radiation. The magnetic field generated by Earth’s liquid iron core shields the planet from 99.9% of harmful radiation. However, in space, radiation is a serious hazard. The radiation dosage from the shortest round trip to Mars is about 0.66 sieverts, which is equivalent to receiving a CT scan every five or six days.

“The atmosphere holds carbon dioxide and other gases that keep the planet warm and protect its surface from radiation.” Again, radiation is a bad thing, so the atmosphere helps with that as well. It keeps the good gasses in (the bad, too, unfortunately, though I think it keeps some gasses out as well) that would otherwise make Earth impossible to be sustain life.

It is assumed that Earth and Mars are in Circular orbits. The initial relative phase angle is stated to be 30o. Calculate the transfer orbit of a time of flight (TOF) 120 day. The orbital parameters such as ΔVs must be calculated. In addition, the propulsion considerations must be evaluated for the case when mission is to be Evaluate the orbital parameters, ΔVs and propulsion parameters when the mission is to be executed by a 500 kg spacecraft, which utilizes 450 s specific impulse propellant.
