The idea of life on a planet other than our own has always interested me, from the time we studied Outer Space in third grade to be exact. I have heard over and over again that there is a chance Mars could have some forms of life living on it today. I decided to find out more about this possibility of life on Mars.

NASA is currently researching this mysterious planet in order to find out if there is in fact life. For fifty years, they have been creating and launching spacecraft into orbit around Mars or actually to land on Mars. Scientists that work for NASA know that Mars is the one place in the Solar System that is most like Earth, however there are still many differences that divide the two. Some of these differences include: Mars does not have a magnetic field, Earth has much more air than Mars, and most of the water that exists on Mars is ice because of the low temperatures that exist on this planet (Not to mention, Earth has a lot more water than Mars to begin with). These differences sort of support the idea that it would be very hard for life to live and sustain itself on Mars.

Large, dry channels show that at one time there was an abundance of flowing water on Mars, much like Earth today. In 1996, a meteorite was discovered by a group of scientists. On the inside of the meteorite evidence of bacteria was found. Perhaps, many years ago, life did exist on this planet. Today, however, it just is not likely.
