Why don t space shuttles burn up in the atmosphere?
“Objects coming back from space are traveling at many times Mach speed — faster than the speed of sound — so to keep from burning up or breaking up they must be protected from the intense heat caused by that friction.” …
Why do space capsules get so hot as they’re enter Earth’s atmosphere?
Any vehicle coming back to Earth from space encounters friction with the air in the atmosphere upon re-entry. This causes it to heat up.
What do NASA scientists know happens to shuttles as they’re enter Earth’s atmosphere?
In 2003, the space shuttle Columbia and its seven crew members burned up as they were returning to Earth. After investigation, NASA discovered that damage to the left wing (that actually occurred during liftoff), let hot air in upon re-entry and caused the shuttle to lose control and burn up.
Do things burn leaving the atmosphere?
It’s about velocity. Objects that enter Earth’s atmosphere burn not because they are falling from great height, but because they are traveling through the atmosphere at great speed. The energy density is sufficient to cause atmospheric molecules to dissociate, and their component atoms to become ionized.
Why dont spaceships go straight up?
Rockets have to tilt to the side as they travel into the sky in order to reach orbit, or a circular path of motion around the Earth. This steering technique is known as a gravity turn, which uses Earth’s gravity to help conserve rocket fuel and minimize stress and strain on the spacecraft.
What does it feel like to re enter the atmosphere?
And what you realize is you’re looking from the inside of a fireball outward. You’re inside the air that’s being ripped apart as you’re re-entering the atmosphere. Very little feeling, no shaking, no vibration, but you just see the heat that’s being generated by the space shuttle entering the atmosphere.
Why is it so hard to break through the atmosphere?
The issue is really gravity. Gravity holds the atmosphere on the Earth otherwise is would dissipate into space. The rocket does two things. It provides enough thrust to defeat the pull of gravity.
Can an aircraft bounce off the atmosphere?
You can’t bounce. When a spacecraft is reentering the atmosphere from some altitude, it will lose some energy. If it gets too hot, it will blow up. If it loses just enough energy, it will land.
What happens when a spacecraft re-enter Earth’s atmosphere?
Spacecraft re-entry is tricky business for several reasons. When an object enters the Earth’s atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast. Luckily, the Earth’s atmosphere contains particles of air.
Why can’t we re-enter space with spacecraft?
Spacecraft re-entry is tricky business for several reasons. When an object enters the Earth’s atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast.
How do space shuttles descend through the atmosphere?
Descent through atmosphere: After it’s safely out of orbit, the shuttle turns nose-first again and enters the atmosphere belly-down (like a belly-flop) to take advantage of drag with its blunt bottom. Computers pull the nose up to an angle of attack (angle of descent) of about 40 degrees.
What is the speed of the Space Shuttle during reentry?
When reentry or blackout occurs, the Shuttle is traveling at 16,700 mph. After reentry the Shuttle uses Earth’s atmosphere to slow down. Landing speed ranges from 213 to 226 mph (343 to 364 kilometers).
