Red planet posting

1. What I saw in the movie was that the men could breath on air, so I thought that we could breath on Mars. Dr platt says that the oxygen levels are far too low for them to be breathing especially when the bugs ate a lot of the algae. 

Another thing that I saw in the movie is that the commander could turn off gravity with a switch and I didn't think that it worked that way. Dr platt had proved what I thought, gravity can't be turned off and on with a switch 

I didn't think that there could be fire in space since there is no oxygen levels in space and in the movie it shows the commander trying to push the fire into space. Dr platt says that there could be fire but she as a character had to be weightless and she didn't show that.

I also saw in the movie that when they landed they landed pretty hard and since gravity is significantly less on mars they. Should have had a safer landing, or that's what I thought. Dr platt proves what I thought here as well. Gravity is less on mars so it wouldn't be as rough as a landing.

What I saw in the movie was they used a radio to communicate with the commander. What I thought was that since there are no radio towers in space and on mars they couldn't communicate but dr platt says that you can, but not from a radio that is 50 years old. 

I thought that the sky was blue because it reflects off the ocean. What I learned was that it's scattered blue light from the sun. 

I always thought that the North Star was the brightest star in the sky that lead you to home but what I learned is that it's only medium brightness and isn't the brightest star. 

I thought that the seasons change as the earth gets closer and further away from the sun. What I learned was that the seasons actually begin a month before then when we say they start and it's due to the solstice.
