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
What else can I help you with?
When did space lose oxygen?
Space does not "lose" oxygen as it is a vacuum. Oxygen is present in the Earth's atmosphere, but it becomes extremely sparse as you move away from the planet. The lack of oxygen in space can make it uninhabitable for humans without proper life support systems.
How can oxygen be efficient for space discovery?
Oxygen is used in the launch of space vehicles to make discoveries.
How do astronauts get oxygen into space?
They carry it with them on board.
How does Chemistry helps in space travel?
It helps scientists know how much of what is needed to make for example the fuel or how much of gases they need to give the astronauts oxygen.
If there is no oxygen in outer space what is there?
Space junk, stars, planets and no vacums Nij ok???
How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
WHy is it important to have an atmosphere?
it is important because if they don't know the temperature they
How do astronauts get oxygen in space?
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.
How can fire lighten in space without oxygen if there is no oxygen then how can a space shuttle come back?
The space shuttle is able to fire its engines in space because it takes the needed oxygen with it.
What type of oxygen is in outer space that make us use helmets?
There is no oxygen in space. Astronauts have to take oxygen with them.
Why do space rockets have to carry a supply of oxygen?
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.
Would a box of matches work in space?
There is no oxygen in space and fire needs oxygen.
Do they have oxygen in space?
While space itself does not have oxygen, astronauts have access to oxygen on space missions through systems that generate and regulate the supply of breathable air. This is necessary for them to survive in the vacuum of space.
Why are oxygen tanks and space suits needed to explore in space?
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.
Why do rockets engines in space have to carry their own oxygen?
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
Can a tree go in space?
Technically speaking you could send a potted tree inside a spaceship into space, however if you took it outside the spaceship it could not survive as there is no oxygen on the moon or in space in general that we know of.
How to calculate when you run out of air in an enclosed space?
To calculate how long it takes to run out of air in an enclosed space, you need to know the volume of the space, the rate at which you consume oxygen (your metabolic rate), the initial oxygen level, and the concentration of oxygen in the space. You can use these values to determine the time it takes for the oxygen level to drop to a critical level where it is unsafe to breathe. Consulting with a safety professional or utilizing specialized software may also help in making more accurate calculations.
