COM 1301, Section 05 October, 9th 2012 Mars Search Laboratory (MSL) Life on earth is getting more and more difficult, earth is overpopulated and global warming is treating our existence on earth every day. Living on another planet is on the etymon that may pop out in our mind, this solution is what a space rover is trying to answer. In exactly one month and three eld ago, a high technology rover lander on Mars, for those who did not hear well-nigh it let me show you some pictures (showing pictures to the audience), the rover is about 1000kg and a railroad car size.Curiosity is special because it process information for itself and then sends the result back to earth. Two main objectives of Mars are1. Discover traces of past life.2. Analyze Mars habitability It is difficult not to get excited about NASAs Mars Curiosity rover, its the most ambitious exploration vehicle yet sent to Mars.The big accomplishment question for the Mars Exploration Rover is how past water activity on Mars has influenced the red planets environment over time.While there is no naiant water on the surface of Mars today, the record of past water activity on Mars can be found in the rocks, minerals, and geologic landforms, particularly in those that can only form in the presence of water. Thats why the rover is specially equipped with tools to study a diverse accumulation of rocks and soils that may hold clues to past water activity on Mars. Project scientist Grokzinger says Curiosity is not a life detection mission. We are not really looking for life, we dont have the ability to detect life if it was there. But let me show you something (shows picture of river ) this river is located in Spain, it reaches high temperatures about 40C and its very acidic, it has a Ph about 2, knowing that the Ph scale goes from 0 to 14 from the most acidic to the least(prenominal) acidic. Well, surprisingly this river holds life Scientists have recently taken a sample from this water and discover bacte ria in it This can be the absolute prove that life can emerge from extreme conditions.A part from discovering traces of past life, the other mission of Curiosity is to identify if Mars can be a encourage of life, Mars Science Laboratory is equipped with an instrument that measures the level of radiation. This will be critical to put a man on Mars and even up the type of protection. At last but not least, Scientists expect from Curiosity a major discovery, it involves analyzing rocks of the landing area, hoping to discover traces of past life and analyzing Mars habitability.To leave off let me show you the latest picture received from the rover (showing picture trace of robot step) as you may see, this is a trace of the robot on the sandy surface of Mars, this is a small trace of a robot, a giant leap of mankind, Thank you.
