Why do astronauts sleep upright?
They do not. Astronauts in space are effectively weightless, so for them, there is no up or down; the idea of "upright" has no meaning.
How could working underwater help astronauts practice being in space?
Because if weighted properly, they can be neutrally boyant. In other words, they're as close to weightless as they can get on earth. The astronauts train underwater to give them a sense of what its like to do their task while weightless and also to practice the peocedures required for their task. The first astronaut to take advantage was Buzz Aldrin when he trained for his Gemini 12 mission. Aldrin was and is still an avid scuba diver. He noticed the similarity between water and space. His succees on Gemin 12 made underwater training the norm for all astronaut extravehicular training.
If objects are weightless in space why can't an astronaut push the space shuttle by the power of his own muscles?
weightless is just a figure of speech. things in space are just lighter than they are on earth. the space shuttle weighs 220,000pds so in space it might weigh 100,000pds.
Why do astronauts use space pen?
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper
Why zero gravity causes problems for astronauts?
I think it is because the human skeletal system is built to support your weight. Once you have no weight, it stops functioning correctly. Astronauts coming home from the MIR space station had significant bone deterioration after their 6 month stay in space. M uscles don't work as well either, very little energy used to lift stuff in a weightless environment.
Are astronauts in a space shuttle weightless?
yes there are
When are astronauts in space weightless?
i like turtles
Why do astronauts feel weightless in a space shuttle?
Because of gravity
When astronauts appear weightless it is actually because they are actually in what?
They are in the vacuum of space.
What causes astronauts to become weighless?
the absence of the gravitational force or field in space causes the astronauts to become weightless
Why do astronauts sleep upright?

Are austronaughts really weightless in space?
Yes, but they do have the same mass. Weight is based off the effect of gravity pulling something down, because there is no gravity in space astronauts are weightless.
Do astronauts lose their memory when weightless?
No, astronauts do not lose their memory when they are weightless in space. However, some astronauts may experience temporary cognitive changes due to factors such as radiation exposure, sleep deprivation, or stress, which could affect their memory.
Are astronauts weightless in orbit?
As there is no gravity in space, everything will float........... Because They're in free fall ........
How do astronauts in space determine their mass even though they are weightless?
Here is, how: http://urvilag.hu/article.php?id=3489
How does gravity hold the solar system together?
There is no gravity in space, everything is weightless.
Why do the passengers on a high flying airplane not appear weightless similar to the astronauts on the space station?
Airplanes do not fly high enough to be unaffected by the force of gravity.
