What else can I help you with?
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.
When spacecraft goes on moon how it revolves after leaving earths gravitational pull?
ahhh now.... When a spacecraft leaves earths atmoshere it does not leave earths gravitational pull! the moon itself is in earths gravitational pull. which is what stops the moon from floating away so as far as i can imagine if you put a space craft on the moon you have not left earths gravitational pull or the E.G.P
What is an aeroshell?
An aeroshell is a heat-resistant shell which protects a spacecraft while it is travelling through the atmosphere.
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.
How high can the altitude be before you burn in the heat of the earths atmostsphere?
When the altitude on Earth increases, the temperature decreases. The reason spacecraft are incredibly hot upon re-entry into the Earth's atmosphere is due to the friction of the molecules in the atmosphere on the spacecraft, which are traveling at extremely high speeds.
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.
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 does the moon appear yellow while rising?
Pollution in the earths atmosphere. That also can make it look brown, orange or red.
What is a natural phenomenon that maintains earths temperature range?
The greenhouse effect is a natural phenomenon that maintains Earth's temperature range by trapping heat in the atmosphere. This process allows some of the sun's energy to enter the Earth's atmosphere while preventing some of the heat from escaping back into space.
Why don't NASA's Rockets burn up while falling back through earths atmosphere?
The rockets have heat cells on the rocket
Earths air temperature vary greatly during the day while its ocean temperature varies only slightly?
The atmosphere has lower heat capacity
