Why does a spacecraft does not burns when it move from earth to space but it burns while returning from there?
When a spacecraft goes into space its speed increases dramatically once it leave the earths atmosphere. When it is returning to earth, it hits the atmosphere at a faster rate than it was traveling when it left. The friction of the atmosphere against the craft, heats it up.
What is the difference between an aircraft and a spacecraft?
Aircraft fly through air and spacecraft fly in space.
What is an aeroshell?
An aeroshell is a heat-resistant shell which protects a spacecraft while it is travelling through the atmosphere.
How do satellites get into space?
They are placed on top of a rocket, which accelerates them until they "escape" the atmosphere and enter space. Satellites are spacecraft that orbit the Earth or a planet, while those that travel through space are usually called "space probes."
What if the design differences between aircraft and spacecraft?
To answer this question ask yourself where do airplanes fly and where do spacecraft fly? You can see most airplanes which fly overhead, but spacecraft fly much higher. Airplanes fly within the earth's atmosphere, while spacecraft fly outside the earth's atmosphere in space. So when you decide to ask a sensible question, post it and you may receive a answer.
Did a rocket ship ever blow up in space?
It blew up while still in the earths atmosphere, not when it was in space
What is a component of the earths atmosphere?
Significant components of the Earth's atmosphere include nitrogen, oxygen, and carbon dioxide.
What is difference between aeronautical and aerospace engineering?
Aeronautical engineering focuses on flying in Earth's atmosphere while aerospace deals with objects outside Earth's atmosphere. aerospace engineering deals with objects inside and outside of earths atmosphere while aeronautical engineering is a more specialized field with aerospace engineering that focuses more on objects inside earths atmosphere. astronautical engineering deals with objects outside earths atmosphere and is another specialized field under aerospace engineering.
Why don't meteors first burn up when they first enter earths atmosphere?
It takes a while for air friction to heat them through. Also some are massive enough that they never burn up but hit the earth instead, becoming what we call meteorites.
Why does the moon appear yellow while rising?
Pollution in the earths atmosphere. That also can make it look brown, orange or red.
Earths air temperature vary greatly during the day while its ocean temperature varies only slightly?
The atmosphere has lower heat capacity
Why don't NASA's Rockets burn up while falling back through earths atmosphere?
The rockets have heat cells on the rocket
