We shouldn't I dont think go to mars because we wont survive because there is 95% carbon-dioxide and only 1% oxygen and we need oxygen to survive. I don't think that we would have enough water and food because the rocket with food and water goes up there every 26 months so they will have to have a lot of food/water. I also dont think that the space suits will be able to withstand the carbon-dioxide. Realistically there going up there to die they have to count on machines. The book that we are reading is becoming a martian.
This week i have also been doing decimals they were fun i did-int quite get them at first but then i caught up then they were really fun.
