Nasa is amazing in my opinion, for the fact that we are able to travel to a completely other place! (I don't mean like going to mexico, like another planet). It amazed me by some of the technology that they have, and the rockets are so cool. I learned that the rocket as they are launching can get very hot so to keep the astronauts safe they have to have insilation to keep them cool and calm. I didn't know that rockets are very heavy. While you are lifting off there is pressure pushing all over the rocket. Astronauts really feel the pressure going into space from the rocket pushing them, I would imagine that they have to take years of training practice to be able to handle it.
