A low Earth orbit is an orbit still in the outermost part of Earth's atmosphere. This kind of orbit occurs a few hundred kilometers into the atmosphere.

Is sputnik 1 still in orbit?
No. Sputnik 1 burned up on 4 January 1958, as it fell from orbit upon reentering Earth's atmosphere
Did a rocket ship ever blow up in space?
It blew up while still in the earths atmosphere, not when it was in space
Why is the Hubble telescope at that height?
Because it shall orbit above the atmosphere but still be at an altitude where it can be reached for repairs by astronauts.
How high above the earth does an orbit have to be?
Orbit can't be maintained in atmosphere. Some temporary low orbits are possible at lower heights. About the lowest possible orbit around the earth is 80 km high, but it will decay rapidly because it is still in the earth's atmosphere (the thermosphere). Even where the atmosphere is extremely thin (only a few molecules of gas in a cubic meter), the friction will eventually slow the orbit of a satellite or vehicle, and it will fall to earth.
Is sputnik 1 still working?
No. Sputnik 1 burned up on 4 January 1958, as its decaying orbit brought into into Earth's atmosphere.
What level of the atmosphere do satelites orbit?
The basic idea is for satellites to orbit OUTSIDE the atmosphere, to avoid losing energy through friction. In practice, there is still a small amount of air, even at the altitude at which they commonly orbit - typically around 200 km or so.

What is a gas that was probably abundant in earths atmosphere 3.6 billion years ago and is still abundant today?
Oxygen

Where does the atmosphere and outer space blend?
There is no sudden change between "atmosphere" and "outer space"; the atmosphere gets thinner and thinner as you move away from Earth. Official definitions of "outer space" usually start at around 100 km above Earth's surface - but please note that this altitude is still too low for satellites, at least if they are to orbit Earth long-term - since they will still get a significant amount of atmospheric drag at that altitude.

What 3 gases made up the earths atmosphere a lot of years ago?
carbon dioxide, sulphur dioxide and still nitrogen
What do you think earths atmosphere would be like today if life had not evolved on earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
Why didnt Felix float when he jumped from space?
Because technically he wasn't in space. He was on the edge of Earths atmosphere. so gravity was still in effect.

Why are some meteoroids visible to the naked eye once they enter the earths atmosphere?
It is so because, some of the meteoroids are of comparatively large size. So when they enter the atmosphere, a big part of them is burnt but still the remaining one enters the atmosphere.
