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
What is the height of the shuttle orbit?
The height of the typical space shuttle orbit is around 300 kilometers (186 miles) above the Earth's surface. This height allows the shuttle to orbit within the Earth's atmosphere yet still be in microgravity conditions.
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.
What happens in the exosphere layer?
In the exosphere layer, the outermost layer of Earth's atmosphere, gases such as hydrogen and helium are present but in very low densities. This is where Earth's atmosphere gradually transitions into outer space. Due to the extremely low density of particles, temperatures can vary widely ranging from very hot to very cold.
What layer of the atmosphere do space shuttles orbit in?
The Shuttle and the ISS orbit in the thermosphere or ionosphere (I think both terms are correct, not sure but I've heard both). This layer starts at 85km and goes up to 600km, after which is the exosphere. "Space" technically starts at 100km. The ISS orbits around 350km, and obviously so does the Shuttle when it is docked, although when it first gets in to orbit the Shuttle is only at about 150km and speeds up over the few days after launch to match its orbit with the ISS. It is still atmosphere because there are stray atoms of oxygen and such up there. In fact there is enough of it that periodically the ISS has to speed itself back up because even though the amount of drag is infinitesimal, it still slows it down slightly over time.
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.
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
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.
Is Luna 1 still in orbit?
YESS! luna 1 is still in orbit.
Can asteroids and comets still bombard your planet - earth?
yes, many objects enter earths atmosphere everyday but are burnt up before they make it to the ground.
What is the height of the shuttle orbit?
The height of the typical space shuttle orbit is around 300 kilometers (186 miles) above the Earth's surface. This height allows the shuttle to orbit within the Earth's atmosphere yet still be in microgravity conditions.
What era began when earths atmosphere formed?
The era that began with the formation of Earth's atmosphere is the Hadean Eon, which lasted from about 4.6 to 4.0 billion years ago. This was a time when Earth was still forming and experiencing intense volcanic activity, leading to the formation of the early atmosphere.
