How do astronautes control temperature in space?
Astronauts control temperature in space primarily through their spacesuits and the spacecraft's life support systems. Spacesuits are equipped with a Thermal Control System that includes layers of insulation and a liquid cooling and ventilation garment, which circulates water to absorb heat from the body. Inside the spacecraft, temperature is regulated using thermal insulation materials and active systems that manage heat exchange with the environment. These systems ensure that astronauts remain comfortable and safe in the extreme temperatures of space.
What term describes the process of returning astronauts to earth from space?
Reentry describes the process of returning astronauts to Earth from space. During reentry, the spacecraft passes through the Earth's atmosphere, experiencing high temperatures due to friction with the air. The spacecraft's heat shield helps protect it from burning up during this phase.
How do astronauts keep their spaceships from melting in space?
Space is cold - colder than you can possibly imagine. Their spaceship is in no danger of melting in space. The danger arises when they re-enter the earth's atmosphere. Then they need either a heat-shield or, on the space shuttle, special tiles which are heat-resistant.
Why might a spacecraft get too cold?
A spacecraft can get too cold in space due to the absence of an atmosphere to retain heat, resulting in rapid heat loss to the surrounding vacuum. Lack of sunlight or proper insulation can also contribute to temperature drop. Additionally, faulty thermal control systems or malfunctioning equipment can lead to temperature regulation issues.

Why do astraunauts cannot burn in the atmosphere?
Astronauts in space don't burn up in the atmosphere because they are not IN the atmosphere. Spacecraft are above the atmosphere. However, the most dangerous part of a space flight is getting THROUGH the atmosphere, on the way up or on the way down. The space shuttle Columbia was destroyed, killing seven astronauts, when the shuttle broke up during re-entry. The Soviet Union classifies spacecraft accidents, but we know of at least a couple when the cosmonauts did not survive the return trip.

How do astronauts depend on zirconium?
Astronauts depend on zirconium for its use in the construction of fuel rods for nuclear reactors that power spacecraft and for its ability to withstand high temperatures. Zirconium is also used in the production of heat shields and protective coatings for spacecraft due to its heat resistance properties.

How do Astronauts overcome G-forces in re-entry?
Astronauts rely on the design of the spacecraft to help absorb and dissipate the G-forces experienced during re-entry. Capsules are equipped with heat shields and parachutes that slow down descent, minimizing the impact of G-forces on the astronauts inside. Additionally, astronauts undergo physical training to prepare their bodies for the stresses of re-entry.

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.

Why can astronauts not use parachutes to help slow down their spacecraft?
Astronauts cannot use parachutes to slow down their spacecraft because there is no atmosphere or air resistance in space to deploy and manipulate the parachute. Parachutes rely on air to create drag and slow down the descent, which is not present in the vacuum of space. Spacecraft use thrusters or heat shields to control re-entry and manage their speed during re-entry into Earth's atmosphere.
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.
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.
