The Planet Mars

What is Mars?

Mars is the fourth closest planet to the sun in our solar system. It is the second closest planet to earth and is considered to have the most liveable conditions for mankind in our solar system other than Earth. Mars is home the largest mountain within our solar system, Olympus Mons, as well as the largest canyon, Valles Manrineris. Mars’ days are only just over 39 minutes longer than an earth day and the seasons are roughly the same as well, but a Martian year is equal to almost 1.9 earth years. Until 1965 many people believed that mars was host to great bodies of liquid water based on the observations of light and dark patches on the planet’s surface. At the current time, Mars has two known orbiting moons: Phobos and Deimos. It also has three functional, orbiting spacecraft: two owned by NASA and one owned by the ESA. The climate on Mars is very cold with the surface temperatures getting as low as -87?C. The warmest that the surface of mars gets is only around -5?C. The cold temperatures are mainly due to the fact that Mars is further away from the sun than Earth so only around 43% of the sunlight that reaches us, goes on to warm up Mars.

What is Mars made out of and how big is it?

Mars is a terrestrial planet (similar in size and composition to earth) that mainly consists of minerals that are mainly made up out of silicon, oxygen, various metals and other elements that are commonly found in rocks. The surface of Mars is covered in Iron Oxide (better known as rust) giving it a reddish appearance and earning it the nickname of ‘the red planet’. The diameter of Mars is around half that of Earth’s. Mars isn’t as dense as earth either. It contains around 11% of Earth’s mass even though it’s volume is equal to over 15% of Earth’s. Mars’ gravity is just under 0.4 Gs (Earths gravity is just under 1 G)

Where is Mars?

Mars is in constant orbit of the sun at an average distance of 230 million kilometres (one and a half times that of Earth’s). Mars’ distance from earth ranges between 54.6 million kilometres to 401 million kilometres, depending on the positioning of the two planets in their orbit. Compared to Earth’s orbit, Mars rotates in a very elliptical fashion.

Can we colonise Mars?

It may be possible to colonise mars in the future. There are some pretty big problems that we would have to face if we wished to settle there though. For a start the temperatures are well below that of what humans are comfortable with. Also the atmosphere is much thinner than Earth’s, so even though hardly any sunlight gets through humans would still burn up much quicker and worse than on Earth. To combat these issues, it might be possible to ‘build’ a new atmosphere for Mars. This is classified as terraforming. Other ways in which we can terraform Mars include flooding it to create oceans. To do this we can melt the build-up of ice around the poles. There are many suggestions as to how we can do this but there would be no point until an atmosphere has been built, as it would simply freeze over soon after. If we wished to colonise Mars it would be a very expensive procedure.

as I have written before ..there are beings residing on Mars ...not like us maybe but of a different frequency and beingness...and someday you may visit after leaving the earth plane...
thank you nihalar
