What protects the spacecraft when it enters atmosphere from space?
A heat shield protects the spacecraft when it enters the atmosphere from space by absorbing and dissipating the intense heat generated due to atmospheric friction. The heat shield helps prevent the spacecraft from burning up during reentry by creating a layer of hot and ionized gas, or plasma, around the spacecraft that acts as a barrier.
How does a spacecraft resist burning up from extreme heat?
As a spacecraft enters the atmosphere, it will travel at a tremendously high speed. The friction from the air rubbing against the spacecraft causes lots of heat. To protect against this heat, spacecraft use heat shields. Most spacecraft use blunt, spherical, or conic heat shields which help slow the vehicle down, and dissipate the heat in the surrounding air. These heat shields are also usually made out of abalative material. Abalative materials sublimate into gas at high temperature. As a result, they absorb thermal energy but erode away as the vehicle enters the atmosphere. However modern spacecraft are being developed to have re-usable heat shields. The Space Shuttle, in particular, uses a series of thermal insulating tiles that absorb and radiate heat while preventing conduction to the shuttle's aluminum skin. These tiles can be re-used many times.
Why does a spacecraft need a heat shield to return to earth?
The speed of reentry combined with air friction creates a massive amount of heat at the point of entry. Heat shielding allows the craft to survive the high temperatures intact, but even a small defect in shielding can be catastrophic.

How does waters heating -holding capacity affect human beings?
It helps the body remove heat through sweating
What is an aeroshell?
An aeroshell is a heat-resistant shell which protects a spacecraft while it is travelling through the atmosphere.
How does water heat-holding capacity affect human beings?
It helps the body remove heat through sweating, and it also allows it to use water as an energy source.

When a space vehicle reenters the Earth's atmosphere energy does kinetic transform into heat energy.?
Yes, during reentry, the kinetic energy of the spacecraft is converted into heat due to air resistance. This heat is generated by the compression of air in front of the spacecraft, resulting in extremely high temperatures on the vehicle's surface. Heat shields are used to protect the spacecraft and dissipate this heat during reentry.

What does the heat shield do on a spacecraft?
As the name implies, a heat shield shields something from heat. In the case of a spacecraft heatshield, it shields and protects the craft itself from the tremendous amount of heat created by air friction due to the extremely high speed of the craft during reentry into the Earth's atmosphere.
Is spacecraft able to land in Venus'?
spacecraft can land on Venus but they melt, it's 400oC,, probes have been sent there but they were destroyed by the heat after a while
