In microgravity environments like outer space, astronauts experience a slight increase in height due to the lack of gravity compressing the spinal discs. However, over a long duration, the lack of gravity can lead to muscle atrophy and bone density loss, causing astronauts to become slightly shorter upon returning to Earth.

Are there farmers in outer space?

Currently, there are no farmers in outer space. However, there are experiments being conducted to grow plants in space for future long-duration missions. These experiments aim to provide fresh food for astronauts and understand how plants grow in microgravity.


How will the mass of a rocket change when it has reached outer space?

NO. the rocket will not shrink,grow,compact,or spread out and stay same size.the stuff in it will stay the same,,,,,,,,,,but the weight will change because there is no gravity to pull down on it. (The mass of the rocket will change continuously from the time it leaves the launch pad until sometime after it has reached space. That's because of the fuel mass it loses, as the engines burn. But once the engines cut off, the vehicle's mass doesn't change.)


Can trees grow in space?

Trees cannot grow in empty space since there are not resources needed for growth, such as soil and water.


How many humans have visited space?

As of October 2023, over 600 people have traveled to space. This includes astronauts, cosmonauts, and private individuals on suborbital and orbital flights. The number continues to grow as commercial space travel becomes more accessible. The exact count may vary slightly depending on how one defines "space" and the criteria for who qualifies as having visited it.


Can the sun grow larger?

Yes, the Sun can grow larger over time as it evolves. In about 5 billion years, it will enter the red giant phase, during which it will expand significantly, potentially engulfing the inner planets, including Earth. This growth is a natural part of its life cycle as it exhausts its hydrogen fuel and begins to fuse helium in its core. Eventually, it will shed its outer layers and shrink down to become a white dwarf.
