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.
Why do astronauts use space pen?
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper
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 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
Are astronauts weightless inside a international space station?
yes
When astronauts appear weightless it is actually because they are actually in what?
They are in the vacuum of space.
A friend says that astronauts in orbit are weightless because they're beyond the pull of earth's gravity correct your friend's ignorance?
Astronauts are weightless in space because there is no gravity in space. The lack of gravity is what allows them to float.
What causes astronauts to become weighless?
the absence of the gravitational force or field in space causes the astronauts to become weightless

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.
Are astronauts weightless in orbit?
As there is no gravity in space, everything will float........... Because They're in free fall ........
What happens to your bones when you are weightless?
What happens to your bones when you are weightless, is that your bones will get weaker and weaker. That is why everyday, astronauts, have to spend two hours on a treadmill everyday of there space expedition.
How do astronauts in space determine their mass even though they are weightless?
Here is, how: http://urvilag.hu/article.php?id=3489
If the space station were in a geosynchronous orbit above the earth would the people be weightless?
The astronauts would experience weightlessness.
