28. How far can we go into space without freezing? (A K2S Question)

From The Space Library

It is even very hard to get very much into our upper atmosphere before we would find the temperature dropping to a chilly -70° F! The troposphere's temperature ranges from 63° F to -135° F. So the key for all astronauts and cosmonauts is to dress in special pressure suits to allow them to feel comfortable in high-flying airplanes and even higher- flying spaceships. Did you know the astronauts have special heaters in their gloves to keep their fingertips from freezing in space?
