25. Is space calm or is it windy and noisy? (A K2S Question)

From The Space Library

Jump to: navigation, search

Since space is a pretty good vacuum, no sound is transmitted and the only noise astronauts hear is over their intercoms if they are on a spacewalk or from fans and equipment on board the Shuttle or ISS. In fact, most astronauts wear some hearing protection while on board the ISS because certain areas of the Station can be very loud due to circulation air fans and equipment noise.
