Can you see the whole Earth from space?
While there are many satellites constantly capturing their views of the earth, most do so at low Earth orbit, a distance too close to see the whole earth at one time.
Other space agencies have taken full-disk images of the Earth since the Apollo missions..
Why are there no pictures of the whole earth?
There are pictures of the Earth from space that show the entire Earth. The reason you can’t see the entire Earth from the moon is because it’s only 250,000 miles away.
Is there a full picture of Earth?
Nasa has released the first picture of the Earth that it has taken in 43 years. The picture, which has come from a camera on board the Deep Space Climate Observatory (DSCOVR), is the first picture of the whole Earth that has been seen since 1972.
Why do commercial airliners fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
How far up do planes fly?
7.2 milesCommercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.
What Earth really looks like?
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. Water covers most of Earth.
What’s the minimum distance that allows us to see the entire earth?
When in a tall building, the horizon can be as far as about 40 miles. From the ISS, the distance to the horizon is over 1,000 miles. So from horizon to horizon, the section of the Earth you can see at any one time is a patch about 2,000 miles across, almost enough to see the entire United States at once.
How many satellites can cover the earth?
When three satellites are required to cover the Earth on GEO, at least 15 are required to cover the whole Earth on LEO. Since satellites at this elevation are moving, many more are required to provide constant coverage. But the lower elevation of LEO satellite constellation also has benefits.
Is Earth perfectly round?
Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.
Can you see the whole Earth from the moon?
The first humans who directly saw the far side of the moon, that is, the side that’s always facing away from Earth, were the Apollo 8 astronauts. If you were camped out on the far side of the moon, you’d never have a view of Earth. If you were based on the near side, you’d see Earth all the time.
Can you take a picture in space?
To ensure they capture a great shot, astronauts always keep eight cameras at the ready in the cupola of the space station, so someone can grab a camera and snap a picture when needed. When it comes to taking photos from the Hubble Space Telescope, the device features multiple cameras to take pictures of space.
At what altitude can you see the curvature of the earth?
35,000 ftVisual daytime observations show that the minimum altitude at which curvature of the horizon can be detected is at or slightly below 35,000 ft, providing that the field of view is wide (60°) and nearly cloud free.
Why doesnt the sun shine in space?
Space is dark because there is no atmosphere to scatter the sunlight. … As there is nothing else in space to shine, hence we never see the Sun’s light.
Why can’t we see the whole earth at a time?
Answer: Earth is very big. The sunlight falls on only one part of the earth at a certain time and the other half is in darkness, that is the reason why we can’t see the whole earth at a time.
What is the highest altitude a 747 can fly?
45,100 ftThe 747 max altitude is 45,100 ft. The 757 max altitude is 42,000 ft. The 767 max altitude is 43,100 ft.
