Technically, there is stuff in space ... atoms of all kinds of elements, mostly hydrogen.
But the stuff is so thin that it's actually a stronger vacuum than can be created in earth laboratories. I've seen estimates like "one atom in a cubic inch", which is awfully thin.
We know that the stuff in space is as good as nothing. Maybe the easiest proof is this:
When a satellite has to plow through any gas in space, it loses energy, its orbit 'decays', and it falls into whatever it's orbiting. The International Space Station, in orbit 'outside' the earth's atmosphere about 240 miles up, loses a few miles off of its orbit every month or so, and they have to give it a bump with a rocket engine to boost it back up to where they want it.
From observing the planets and their moons for the past 500 years or so, including our own moon, we can see how much they're slowing down ... or not slowing down. We can easily calculate how 'thick' the stuff is in space, and the answer is: a few atoms, but as good as nothing. and there are 78 000 000 000 000 000 000 atoms in one grain of sand so how many atoms in space i wonder
Because in space it is all made of carbon dioxide and no oxygen so people are not able to breath in space. The space suit allows you to breath in oxygen because there is an oxygen tank built inside.
no there is no oxygen in space
Oxygen is used in the launch of space vehicles to make discoveries.
It didn't. Space does have some oxygen, it is just extremely thin almost everywhere (except in the atmospheres of some planets).
They carry it with them on board.
Simple. It dosent because air as we know it would be oxygen so, no oxygen in space means no life actually in space cause they would die
They need to take it with them. There is no oxygen in space
No. In space there is no oxygen and oxygen is what you breathe.
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
The space shuttle is able to fire its engines in space because it takes the needed oxygen with it.
it is important because if they don't know the temperature they
There is no oxygen in space. Astronauts have to take oxygen with them.
In space there is no oxygen. Space is a vacuum. All things like a rocket going to space, require a fuel to burn, oxygen and a heater. Since there is no oxygen is space they need to provide it for them. Meaning the reaction can take place correctly.
There is no oxygen in space and fire needs oxygen.
Answer: All combustion reactions require oxygen, since there is no oxygen in space, they must bring it with them.
Oxygen tanks and space suits are needed for space exploration because there is no air in space and anyone there without suitable coverings and sources of oxygen would quickly die.
No. There is no air in space. Our gravity holds in the atmosphere, including Oxygen and other gases.
