- Summary
Mars are a illusion to us. It is surrounded by many secrets. Many scientists have hard been studying about Mars for decades because Mars is enough live tings to live. So, some scientists think we might be not alone in the Universe. That's why Mars are the best interseting subject we have endless tried to explore. Mars are so far away from Earth that only robots can land on now. The pioneer of this study is Peter Smith. He have tried the misson of Mars 7 times. Befor Agust 4 2007, he had never got siganal from his robot which sended to Mars. However, he never give up although Nasa canceld the misson that was suppose to launch as a associated project with his study team. On August 4 2007, his project team sent a robot which called Apropo Phoenix. The robot finally successed to arrive on Mars 9 month later. It has been a great chance to discover about Mars. The first country which sended a robot to Mars was Soviet. After 8 missions failure, Soviet successed to get image of Mars but there was no sign of lives. There are 3 significant conditions for lives to be genrated their lives. First is energy sources such as heat, sun rise, volcano. The second thing is organics to build blocks of lives. Last is solar system. So, Nasa sent two robots which called Spirit and Opportunity to search for sign of the conditions trace like ancient water stream. The robots laid down on a trace of water on Mars. The robots successed to pick some soil. The result was disappoint for sientist. Because the ancient water on Mars was too salty live things to live. The only positive thing is there might be high heat at least. Because the soil is made of silica almost 90 %, there should have been high heat billions years ago. The possibility of exists of water and heat support the idea that it would generate orgainism at the time. However, it is true that there are still many skeptical in the notion.
- Personal Response
The reaon I chose this video is that I alway wonder what if there are the other live on the universe and it is true that few people' insitence about it. The curisity stimulated me to choose this video. To be honest, I was not interseted in space sience and still now. However, I wondered how much the space science technique have progressed. The sientist struggled to have robots land on Mars. They failed many times but thanks to thire patience to reach Mars, they finally successed to survey Mars. Thire preserverance was so impressed that I cannot help admiring them. They are still making efforts to find more information about Mars and It is certain that next generation would discover on better condition we have had from former generation. No matter how much they success the dicovery about Mars, I praise the endless efforts of many scientists and thire inteligence.
