Week 4 : Task 1- Is There Life on a Mars?

• Task 1 is from http://www.pbs.org/video/program/979359664/topic/979380997

I listened 20 minutes.
Is there life beyond the Earth? To find out we might look no further planet next door. Mars maybe the best hope for resolving the ultimate mystery of creation. It is the one planet out of there , has more in common like enough we can imagine with our world than any place of Universe. Mars has some dark secret. Around 4 billion years ago cataclysm event, two young planets emerged both brimming with promise. Peter Smith has been involved 7 missions on the Mars.
1999- POLLO lander about it touch-down on a surface. His team waited for a signal. The POLLO lander disappeared. After the POLLO, NASA canceled the mission. He felt apart. Smith did not give up. His plane to take technology from those fail Mission and reproposed for another lander. Every incoushen will be taken to make sure that this one would make it. Another lander was , it was Phoenix like the golf across to solar sistem.
9 month later (May 25, 2008) if land it Phoenix would be thank to the engineering today who made it happened . But no one knew better than Smith what could go wrong. Time already running out. This is 39 time we tried to reach Mars, the 7 th time they actually landed.
2004, NASA put a vichle on a ground.They were equipped with a sophisticated biology experiment designed to search for microbial life on Mars. It would take a sample of the Martian soil, and then expose it to chemicals that would feed an microbial life in the soil. Some gases were emitted, but most scientists now think that the results can be explained by purely chemical processes.On Earth, wherever there's water, scientists find life; deep underground, under rocks in Antarctica, or inside nuclear reactor tanks. Life always finds a way. And so, the search for life on Mars will involve the search for water.They're hoping to find evidence of organic molecules in the ice, and further clinch the possibility that the raw ingredients for life are on Mars.

I chose this topic because i was wondering is there any life on a Mars? But right now, there's no conclusive evidence of life on Mars, either today, or in the past. Let's hope that changes in the next few years.

• dispatches(v) to send someone or something somewere. NASA dispatches the aptly named Phoenix to see if soil conditions on the Red Planet

• cataclysm(n) a sudden violent event or change, such as a big flood or Earthquake.
