  1. The article was very interesting to read as it has many interesting facts to read.
    My opinion about the article speaks about Mars and its effects and first rock to be examined up close last year by the Mars rover Curiosity a run of the mill volcanic rock. The rock turned out to be anything. Sometime it become like pile of windblown dust and soil. The rocks that exist on Mars, such as Chunk of basalt. Chunk of basalt it is unusual rock type and like terrestrial rocks. On Earth, the magma that hardens into alkaline rocks comes from the melting of rocks deep in the mantle in the presence of water. That suggests that the movement of magma. I agree with ( Grotzinger ) what he said about the water because for hypothetical Martian microbes to drink and maybe can cause thyroid problems. In Conclusion the water undrinkable there in Mars, rocks also sometimes be harmful.

  2. The article was a bit interesting and the fact also has made me want to read more about Mars, by the way I hate everything about space but this article made me change my look about the space. I have been surprised when I read that the rock they had examined turned out to be anything but an ordinary one. I have learnt that on Earth the magma that hardens into alkaline rocks comes from the melting of rocks deep in the mantle in the presence of water and that suggests that the movement of magma in mars is very complex than people. I got shocked when I reached the point that there is water in mars and most of people say that Mars is a dry desert planet. In Mars I think everything is harmful in Mars and the most harmful thing there in mars is the water and here in earth everything is harmless to us.
