What happens to an astronaut's bones when they are in space?
In space, astronauts experience microgravity, which leads to a decrease in bone density due to reduced mechanical stress on the skeletal system. This phenomenon is known as spaceflight osteopenia, where bones lose calcium and other minerals, making them weaker and more susceptible to fractures. Research indicates that astronauts can lose about 1% to 2% of their bone mass per month while in space. To mitigate this effect, astronauts engage in regular strength and resistance training during their missions.
Why do astronauts in space can develop bone weakness?
Astronauts in space can develop bone weakness due to the microgravity environment, which significantly reduces the mechanical loading on their bones. In normal gravity, bones are constantly subjected to stress from weight-bearing activities, which helps maintain bone density through a process called remodeling. In space, the lack of gravitational forces leads to a decrease in bone density, particularly in weight-bearing bones, making astronauts more susceptible to fractures and osteoporosis. To combat this, astronauts engage in regular exercise while in space to help stimulate bone health.
Why do you lose bone density in space?
In space, the lack of gravity-induced pressure on your bones leads to decreased bone density because your body does not need to support its weight in the same way as it does on Earth. As a result, astronauts in space experience bone loss due to reduced mechanical stress on their bones, which can lead to weakened bones and an increased risk of fractures.
Name three types of special equipment astronauts need to work in space?
Space suits: to protect astronauts from extreme temperatures, micrometeoroids, and provide oxygen. Extravehicular Mobility Units (EMUs): for spacewalks to enable astronauts to move and work outside the spacecraft. Tether systems: to keep astronauts connected to the spacecraft while working in space.
How can astronauts perform their space walk and move around as if nothing while the space station is traveling at 17500 mph?
Astronauts can perform their space walk and move around as if nothing is happening while the space station is traveling at 17,500 miles per hour, because there is no gravity. This keeps them from feeling the fast speed.

How astronauts spend their time in the space ship?
astronauts like to exercise while in the ship
What is the name of the space sickness that many astronauts get while in space?
Space Adaptation Syndrome
Do astronauts leave the ISS while in outer space?
no

What do people use as a shower in space?
Astronauts do not shower, they must sponge bath while they are in space.

Why should astronauts exercise regularly while on a space mission?
While in weightlessness, your bone density and muscle mass decrease as you don't use them. So, by doing several hours of exercise a day, you are using the muscles and bones, therefore, the bone density and muscle mass do not decrease as much as they would if they didn't exercise.

Do the astronauts need special clothes while living and working inside the space station?
Yes, astronauts wear specialized clothing while living and working inside the space station. They wear comfortable clothes for daily activities and special space suits for spacewalks or emergencies. These suits provide protection from extreme temperatures, radiation, and microgravity conditions.
Do astronauts need to have a passport while in space?
No , but for astronauts visiting from other nations they do need passports to travel to the respective countries who are launching them into space e.g. the U.S. , Russia .
