If I am in space in a space suit and assuming I have plenty of oxygen, can I float/fall back to earth.?
Also assuming I have a parachute or jet pack and my trajectory is correct at the start. What would I need to do this?
Answers:
First you are initially traveling 17,500 miles per hour, in order to obit the earth.
to fall back to earth you need to slow down.
to do this you'll require a rocket pack, or a chemical thruster, to slow your speed.
now you are falling back to earth. gravity takes over.
with just a space suite, you would enter the upper atmosphere, very little air, not enough air for chutes, the air molecules would bounce off you creating friction, and a lot of heat (remember you are traveling at 17,000 M/hr. chutes only good under 200 miles per hour. you need to slow down, either friction of the air (you would disintegrate, vaporize due to heat) as for a jet pack not enough air, rocket pack, you'll need a couple of tons of fuel to slow you down, and keep your speed down, it's not like a moon landing they did not have an atmosphere to contend with.
BALLS OF STEEL
no way possible as you would burn up in the atmosphere
if you're on the outskirts of the atmosphere then you can, nasa have already done that, but any further and you'll just drift aimlessly
You wouldn't be able to 'fall' with a parachute, as there's no gravity. Also, you would catch fire when you re entered the atmosphere.. probably not a good idea!
No, you will be lost in the space, because you are not under earth gravity, oxygen or space suits has nothing to do to your return to earth.
nope u won't make it threw the ozone layer budd u'll be a floating object useless with no meaning to human nature. sir you'l be equal to a grain of dirt on a 2-lane high-way *_* do it
you would drift aimlessly in space till your oxygen runs out then you're dead. If you are close enough to the earth you will be drawn back to earth so fast you'll burn up like a little meteor, I dont think a parachute will help much, you'll need something to slow down your descent with alot more power than that, even a little jet pack on your back wouldnt be enough.
Float! You mean plummet to earth at speeds in excess of 500 mph.
First, you are only going to head for earth if you are in it's gravitational pull. Second you will fry to a crisp the moment you hit the atmosphere.
You will fall back to earth but mostly in dust particles!
No, your speed in space would by 18,000 miles per hour.
you'd need to be able to face the wrong way and them slow yourself down. at about 17,500 you will start to drop. From then on your speed will scrub off and resistance will slow you down. You'll re-enter the earth atmoshere at 14,000 mph. From then on you're in free fall as you have no wings.
You'll die about .00005 seconds into the procedure
and a huge, fire-proof shield to stop yourself burning up like a shooting star and bearing in mind that you'd be accelerating at 10m/second/second from miles and miles and miles above the earth. No, you couldn't.
You remember a little incident with the Space Shuttle Columbia? Let me refresh your memory -
They had plenty of Oxygen
They had the proper trajectory
They were equipped with parachutes
They were equipped with rocket boosters (jet packs)
They also wore space suits.
They had a hole in one of their shields and were vaporized!
You'd be vaporized long before they were. So simply put: No sir.
atmosphere will burn eu..
suit will be gone + ur body..
don worry eu die then eu still go back earth mah.
back onli back 2 hell onli wat...
You'd need something o prevent you from frying up when you enter the atmosphere.
You would burn up in the atmosphere in re-entry to earth. got balls.
If you were travelling at about 700 mph you.d live no bother but you'd need a jet pack the size of a space shuttle liquid fuel tank to slow you down enough.
may be not because earth's gravity doesn't affect you in space.
Yes Captain Joseph Kittinger of the us airforce i think. jumped from a balloon at an altitude of over 100 000 feet in 1960 i think he reached a speed of over 600 mph during the fall back into the atmosphere.
Sure, you can. Don't know what all these people are talking about.
Depending on what you mean by "trajectory is correct at the start", you may not need to do anything at all - just continue following your "correct trajectory", and you'll bump into Earth eventually.
If the trajectory is not all that "correct" after all, you can always change it by emiting oxygen streams (you said, you have plenty) in appropriate directions. It might take some time, but eventually, you should be able to get on the right track (unless, you get captured into a gravitational field of another body and become a satellite - in that case, you'd need way too much oxygen and hell of a lot of pressure to be able to escape).
If you're on the outskirts of the atmosphere then you can, NASA have already done that, but any further and you'll just drift aimlessly...rather like you are doing now!
Sorry for plagiarising part of your answer Aphextwig
Why would you want to do that ? sounds a bit daft to me the question is how would you get up into space in the first place ?
I am pretty sure you would burn up on re-entry. Jet pack sounds like fum though.
Drifting aimlessly.how fast are you going if you are drifting aimlessly and far could you get.that sounds like fun ^_^.
no is the answer my friend, as you would need a fair old velocity to re-enter the earths atmosphere, you would merely bounce of and float away...however, if you before your space walk had had a good meal containing an ample amount of sprouts, washed down with several litres of cider, and had a small vent and an ignition system fitted in the rear end of your space suite, you may well regain entry into earths atmosphere, think you might want to hold your breath for a while though.
