How much is a space suit?
It is difficult to express the cost of the suit; not all parts are made by ILC, It has been reported in the news media that the spare suit costs two million dollars.
This does not mean that each time the suit is used it costs two million dollars..
How much fuel is needed to reach Mars?
When it comes time to take off from the Martian surface, the MAV will need 33 tons of propellant to break free of the red planet’s gravity, push through its atmosphere, and safely ferry the astronauts and their scientific cargo into orbit, where they can rendezvous and dock with their Earth Return Vehicle.
Does a body decompose in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.
Can you come to a complete stop in space?
No. Even if you manage to define a good universal reference frame, you still can never fully stop. Even if you are just “in space” you are already somewhere, which limits, by the uncertainty principle, the precision with which you can determin your momentum, thus you can never fully be at rest!
Do satellites run out of fuel?
Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris.
Why do Rockets need fuel in space?
Because it operates where the air is too thin to provides enough oxygen, a rocket carries its own oxygen in tanks and mixes it with the fuel just before it is burned. Rockets not only make space exploration possible, but they also enable us to explore our own planet in ways we could never do even from an airplane.
What fuel is used for space travel?
liquid hydrogenToday, liquid hydrogen is the signature fuel of the American space program and is used by other countries in the business of launching satellites. In addition to the Atlas, Boeing’s Delta III and Delta IV now have liquid-oxygen/liquid-hydrogen upper stages.
Can you accelerate indefinitely in space?
Yes, you can in theory accelerate forever. However, you can never reach the speed of light. This speed is usually called “c”. … Each time you pressed it, you’d be going faster – but you’d never get to the speed of light because each new speed increase is too small to reach c.
What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts. Image source: LubosHouska; CC0.
Does your head explode in space?
The vacuum of space will pull the air from your body. … Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode. Your skin is elastic enough to hold you together.
Can you stay still in space?
Our universe works similarly, but we’re embedded on a three-dimensional space instead of a two-dimensional one. There is no ‘still’ that is not relative to some other object. So yes, you can be still with respect to one object, but you’ll be moving with respect to every other object.
What happens if you run out of fuel in space?
Space ships do not stop when they run out of fuel. … As a result, there is essentially zero friction in space to slow down moving objects. Unlike ships in water, a ship in space does not need constant thrust to keep moving forward.
Is space in a vacuum?
Space is an almost perfect vacuum, full of cosmic voids. … But the vacuum of space is the opposite. By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty.
What happens to astronauts bodies in space?
In space, astronauts lose fluid volume—including up to 22% of their blood volume. Because it has less blood to pump, the heart will atrophy. … When gravity is taken away or reduced during space exploration, the blood tends to collect in the upper body instead, resulting in facial edema and other unwelcome side effects.
