The Mariner 4 was the first spacecraft to visit the planet in 1965, but the first spacecraft to land on Mars was Mars 2. There have been many other rovers collecting data and pictures throughout the years since there have been no manned missions. The elliptical orbit that Mars possesses contributes to the climate here. The temperatures typically range from -207 degrees fahrenheit to 80 degrees fahrenheit. Earth and Mars have about the same surface area even though Mars is significantly smaller than Earth. Mar’s surface contains volcanoes, canyons, craters, and much more. There are many land features that this plant possesses. Although we can’t see the land features from a telescope we know this because of the rovers that on Mars. Because of it has a lower density than most other planets scientist believe that the core contains large amounts of iron and iron sulfide. Since there is no evidence of plate tectonics presently, this explains why the planet has enormous volcanoes on its …show more content…
In order for this to be attained, we will have to compare the two planets to see if life will survive on Mars. The similarities between Mars and Earth include: “seasons, polar ice caps, volcanoes, canyons and weather” (Dunford, "Mars: Overview: The Red Planet."). Although there are some similarities between the two planets this doesn’t necessarily mean that humans can survive there. Mars is 1.5 times farther from the sun than Earth is. The planet is also elliptical, so that means that the distance from the sun is not always the same. The seasons on Mars would be different than on Earth because of these reasons. There is evidence from NASA’s Mars Global Surveyor that parts of the crust are highly magnetized which indicates that there was once a magnetic field millions of years ago, but as of now Mars does not have a magnetic field. Magnetic fields act as a barrier from space and the planet. Some scientists believe that Mars was stripped from its water from solarwinds. They believe that solarwinds were able to affect the amount of water the planet had because it does not have a magnetic field. This theory is not believed by all scientists because hasn’t been proven, but if it were true, it would explain why Mars had water on it’s surface millions of years ago. There is no liquid water on the surface of the planet, but NASA’s Mars Odyssey orbiter had detected evidence of water ice below the surface
