Why doesn't the space shuttle burn up upon entering the eath's atmosphere?
The shuttle spacecraft does nort burn up at all when it does reenters the earths atmosphere, even of the heat. The reason is that there are all heat preventing tiles on the spacecraft from burning, and keeping the astronauts safe.
Why might a spacecraft get too cold?
Because the average temperature in space is just 2.73 degrees above absolute zero in the Kelvin scale. After their oxygen tank exploded, the Apollo 13 astronauts were forced to shut down their spacecraft to conserve battery power necessary for re-entry. Following the shutdown, the temperature in the spacecraft dipped to near freezing temperatures. The only reason it didn't freeze was because they were heated by the sun for most of their journey. When astronauts went to the moon, they put their spacecraft in what was known as a barbeque roll to even out the temperatures both inside the spacecraft and back in the Service Module where their oxygen and fuel tanks were. Had they not done that, half of their spacecraft would have been frozen while the other half overheated.
How do astronauts return to earth?
Through a slow and controlled descent.During the space programs Mercury, Gemini, and Apollo, astronauts returned to Earth through a sort of crash landing. They fell through the atmosphere using a heat shield to deflect the massive amounts of heat built up do to the friction of the Earth against the spacecraft. When they were nearing the Earth's surface they deployed a parachute to slow them down. They then fell into the ocean, the spacecraft floated, and they were retrieved by a Navy rescue team. Then the spacecrafts could not be reused, they were a once only deal. Now the Shuttle lands much like an airplane does. It reenters the atmosphere and uses a heatshield of its own to deflect the heat. It has wings on the side which allow it control over its decent and it lands on a runway, also using parachutes to slow it down after it has touched down. The benefit of this style of landing is that the spacecraft is reuseable and can fly several missions.
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.

How did the Apollo team compensate for the heat on the moon?
They mostly used thermal blankets to shield the equipment and the Lunar Module from the intense heat of the sun. The astronauts were protected from the heat by their space suit and with cooling water which flowed continuously through their undergarments.
How are astronauts protected in space?
The space suit is what protects the astronauts the most, if they did not have these then there would be no more travelling to the space. Astronauts come across very extreme temperatures but luckily they are protected with their complex "suit of armour" that is snug fit and fully tight. At an altitude of 400 kilometres, the temperature can approximately drop from 120 °C to 150°C in a matter of minutes.
Can you heat the water in satellite?
Yes. Just like astronauts can heat air in a satellite you can heat and boil water.
How do astronauts control temperature while on a space mission?
Strangely, both heating and cooling are required in spacecraft: radiant heat is constantly being lost to the cold of space, while the radiation from the Sun will rapidly heat any object in orbit around the Earth or Sun. Spacecraft use both passive and active temperature controls. Reflective materials and coatings prevent the buildup of heat from the Sun. Active systems remove heat from the sunward side and use it to warm the interior. For astronauts outside a spacecraft, excess body heat has to be removed from their cramped spacesuits, while the suit exteriors insulate them from both the Sun's rays and the frigid cold of space.

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
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.
How were viking houses protected from the winter?
Viking houses were protected from the winter by using turf or sod walls, which offered insulation and kept the heat inside. The roofs were thatched with straw or reed, which provided additional insulation. Fireplaces or hearths were also used inside the houses for warmth and cooking.
