This makala is kwa Alicia Chang, AP science writer. Written on Thursday, April 21, 2011 at 6:18 ET. As usual I typed into bin “Current events” and opened the link to Yahoo News, clicked the science tab. It usually takes some searching to find a good makala but this time the first makala was just perfect. I saw a picture of what looked like a crater on mars however, the title proved way zaidi exiting. There was no tarehe specified for when this discovery took place. The makala is on a large dry ice lake that was discovered on mars, one that probably formed 6000,000 years ago.
    600,000 years zamani in mars the atmosphere was much zaidi dense, there was much zaidi carbon dioxide in the atmosphere, because of this the dust had an easier time lifting off; causing deadly dust storms much like what took place in the American dust bowl in the 1930s, but much worse. The atmosphere has since frozen. “Mars lacks a molten core that provides a magnetosphere that in the past protected it's atmosphere.” Eric alisema in one of the replies. “Without a magnetosphere, Mars cannot protect and/or maintain a significant atmosphere. From everything I've seen and read, fantasies of terraforming Mars are ridiculous from that standpoint alone.” alisema Wtfk in another reply. (All grammar and spelling mistakes are made kwa the original writer, I only copied and gave credit.) The lack of significant atmosphere creates a lack of greenhouse effect so the planet is much colder now.
    This makala falls under the category of astronomy because of the fact that it all takes place in outer space, au Mars zaidi like. It also deals with atmospheric conditions, magnetic fields, and molten rock. Some of this was already studied in class before, and most of the rest of it I am sure is to come, but not in so much detail. The fact that it covers zaidi than one region of earth science sparked my interest, this may have happened before without me noticing until now. But I found myself practically on the edge of my kiti, kiti cha kusoma this makala and the comments, until someone had to make a wise crack at Japan that made the guy sound so stupid.
    This makala basically shows that it is not really possible to colonize mars, let me re-quote Wtfk “From everything I've seen and read, fantasies of terraforming Mars are ridiculous from that standpoint alone.” As well as the fact that it increased my understanding of the earth itself. With some of the information here we may be able to conclude that there may have at one point been life on mars, but not anymore, and this was zaidi than 600,000 years ago. The knowledge that this makala supplies may be helpful to me at some point, and may be worth consideration for the rest of the world, It shows that nothing lasts forever and if my theories are correct, Earth may end up just like Mars someday.
