How is time kept for astrounaughts?

Question

1. How many times does the space station rotate the Earth a day?
2. How frequent do the austrounaughts sleep?
3. If an astraunaught spent 1 year in space ... would this age them or keep them young?

Answer 1

If they stayed up a year at 7.7 km/s and that year is considered to be 365 days, they would have aged by only 364.999 999 8795 days.

PS: astro Naughts-- Funny!

Answer 2

1. The ISS (the only space station in space right now) orbits once every 90 minutes or so, so the astronauts get 45 minutes of sunlight followed by 45 minutes of darkness.

2. They have a normal sleep schedule, 8 hours asleep and 16 hours awake. When on the space shuttle, I believe they keep their watches set to Central Time - the time in Houston (mission control) but I could be mistaken. Not sure about the ISS, though.

3. He or she would age a year in space just like on Earth. Actually, since they are exposed to a bit more radiation in space, they might "age" more than a year. The longest anyone has ever spent in space at one time is 438 days, a record held by a russian cosmonaut on Mir. http://hypertextbook.com/facts/2006/KieshaHarding.shtml

Answer 3

1. Which space station? ISS orbits earth approximately 16 times a day.

2. If you meant astronauts, they sleep "normally", once every day for several hours, unless they have special duties for the night in which case they may be awake for longer periods of time, like soldiers on guard duty or doctors on night shift at a hospital.

3. Even though ISS travels at a speed of about 7.7 km per second, that's still far too slow for any noticable effect of time dilation. After one year on the space station an astronaut would be aged by one year, but he might suffer from muscle atrophy and deterioration of the bones due to the extended period of weightlessness.

As for time keeping, many types of clocks work in weightlessness without problems, so this isn't really a challenge.

Answer 4

0. time is relative to a point on earth for astronaughts
1. space station orbits the earth 15.72 times per day
2. the astronaughts sleep once a day, for about 8 hours
3. if an astronaught spent one year in space, it would theoretically make them a little bit younger than people on earth, but its very neglible

bonus: if you misbehave on the ISS, are you astronaughty?

Answer 5

O N E question at a time.
And before you are looking for such answers, I would try and learn how to spell words first ... :-))
1. one time every 90 minutes
2. as often as you do
3 of course aging, because time doesn't run backwards.

Answer 6

there is no such thing as an astrounaught
the space station does not rotate the earth

Answer 7

The time is beamed from an atomic clock.

The rest depends on the frequency of the station's orbit.

Answer 8

they will probably age, but i highly doubt you will look like a 60 year old in space.....THERE IS NO GRAVITY!! nothing to give you wrinkles and pull down your face.

Answer 9

What the hell is an astrounaught?

Answer 10
