At first, the skin turns red in the area of the infection, and a tender lump develops. After four to seven days, the lump starts turning white as pus collects under the skin. If the infection spreads to the deeper tissues of the skin, then it becomes an abscess or furuncle.
The International Space Station cruises at about 17,500 mph. The International Space Station has an average elevation of about 220 miles when orbiting Earth. Every hour and a half, the International Space Station completes an orbit around Earth.
Imagine being chased by a 925,000-pound machine traveling at 17,500 miles per hour. That's what's happens when astronauts dock with the International Space Station. Surprisingly though, the process can take a lot longer than you'd think. Although a rocket can transport astronauts into space in less than 10 minutes, it takes hours, and even days, to rendezvous with the International Space Station.
