Thank you Tamar for the question. The answer to your question is that it would be about the same amount of air needed to survive as you do on Earth. On earth, we all know that there is plenty of air to breathe, but on Pluto there is a different atmosphere. You would need a spacesuit to carry your air with you... There is not much we know for sure about Pluto's atmosphere, but it is made up of mostly nitrogen with some carbon monoxide and methane and very thin. Not only that, but most of the time Pluto's atmosphere is frozen into ice. Because of this, an astronaut visiting Pluto would need a spacesuit to keep them warm and give them air to breathe. The amount of air needed would be very similar to what this astronaut would need on other planets. The small difference is that Pluto is not a very big planet and has alot less gravity than here on Earth. This means that if you were the astronaut trying to do work or go places on Pluto, it would take less energy to move yourself (have you ever seen the movies of astronauts hopping across the moon?). On the other hand, you have a big, bulky suit to move around, which would take more energy. The temperature shouldn't be a problem, as you would have that controlled through your suit (it would have to be pretty warm for Pluto's low temperature of -235 degrees Celsius). So, maybe you can say that you use about the same air there on Pluto if you were doing similar activities here on Earth, but wearing a spacesuit... I hope this helped. Tye "Mad Scientist"
