Distinguishing Features

Mars is known as the Red Planet, an appearance it gets from the surface being rich in iron oxide, a dust that covers the planet.

Much like Earth, Mars has two polar caps .

The surface of Mars is covered in over 43,000 large impact craters and many more besides that remain undiscovered.

Where is it in our Solar System?

Mars is the fourth planet from the Sun, sitting between Earth and Jupiter, at an incredible 142,000,000 miles, or 1.5 AU from our central star.  That is one and a half times the distance between the Earth and the Sun.  You would need to walk around the Earth’s equator over 5,700 times to equal that distance.

Interesting Facts

So far, Mars has the largest mountain in the Solar System, it is roughly three times the size of Everest at a staggering 15.6 miles high! The mountain is called Olympus Mons.

Mars is prone to huge dust storms enveloping and sweeping across the surface.

Currently, Mars is the only planet that we know of, that is completely inhabited by just robots.  This is due to the missions that humans have led to the Red Planet in which they can get the machinery to Mars, but have not been able to get the robot explorers back to Earth, so they instead roam the surface of Mars collecting data and sending it back to us, until it malfunctions.

  16. Interesting blog post. Some tips i would like to make contributions about is that computer system memory should be purchased if the computer still cannot cope with everything you do along with it. One can put in two RAM memory boards of 1GB each, as an illustration, but not one of 1GB and one with 2GB. One should make sure the maker’s documentation for own PC to make sure what type of storage is required.

  17. I’ve learned some new things through your weblog. One other thing I want to say is newer laptop or computer operating systems are inclined to allow far more memory to be played with, but they likewise demand more memory space simply to function. If a person’s computer is unable to handle additional memory and also the newest software package requires that memory space increase, it can be the time to buy a new Personal computer. Thanks

  18. One thing I want to say is that often before acquiring more pc memory, consider the machine in which it would be installed. In case the machine can be running Windows XP, for instance, the actual memory limit is 3.25GB. Installing above this would basically constitute any waste. Be sure that one’s mother board can handle the particular upgrade amount, as well. Good blog post.

  20. What I have observed in terms of pc memory is always that there are technical specs such as SDRAM, DDR and the like, that must fit the specific features of the mother board. If the personal computer’s motherboard is very current while there are no operating system issues, improving the storage space literally normally requires under an hour or so. It’s on the list of easiest computer upgrade treatments one can consider. Thanks for sharing your ideas.
