How does satellite imaging in the sky work?
Satillite imagining is a process where a satelitte in space is sending beams to various places on earth. these later take pictures and send it to earth

Satellites Visible in the Night SkyAbsolutely! Especially late dusk when their solar panels catch the sun and shine it your way. The International Space Station is the third …brightest object in the sky, only surpassed by the sun and the moon. If you are using Ubuntu go download GNOME Predict, of simply search for "Space Weather Simple satellite Tracker".

They are put into orbit by shuttles and stay in orbit around the earth, like the moon. Since they are no longer affected by Earth's gravitational field, they will not naturall…y fall down to Earth.
Because space has no gravity to pull them down.
The satellite is actually trying to fall away from the Earth, but gravity keeps it nearby. Also, the satellites have small rocket motors to keep adjusting it's positio…n to keep it in the same spot.
You get images from a satellite using a frequency band. The best way to access satellite images is with Google maps. However, if you want your own, you will need to have at …least $500 USD, and for larger areas up to $14,000. Look at Digital Globe for these.
about a 100 basket-ball sized satelittes fall every year.
At night, you can see: -- The Moon -- The International Space Station -- The Space Shuttle, during a mission -- The Hubble Space Telescope For any one of them, you have t…o know the proper time and direction to look.
Interestingly enough the sattelites are doing their level best at falling from the sky. The whole idea is that at orbital velocity the objects move forward fast enough tha…t they continously miss the Earth as they fall down. In the ideal case satellites are in orbit. This means that they circle the Earth at a specific speed and a specific height. Because satellites aren't in Earth's atmosphere nothing slows them down. If they did slow down it would reduce the height they orbit at. If the height were reduced they would encounter thicker air which would slow them down more, which would lower their height more. This cycle would continue until they crashed. In actuality the satellites do slow down very slowly because the air is not totally absent. Eventually all satellites will fall from the sky.
Satellites may fall out of the sky because they get too close to Earth. In that case, Earth overwhelmed the power of the satellite's propelling system and slowly but surely dr…agged the satellite into the Earth's atmosphere.
When we look up from the earth, we are looking into the atmosphere. The atmosphere appears blue because its gases scatter solar radiation in the longest parts of the visible p…ortion of the electromagnetic spectrum. Satellites are above the atmosphere, so when they look out they see the black vacuum of space (there is nothing in space, and black is the absence of color). When they look down at the earth, they "see" through the atmosphere to the earth's surface, or to the clouds that are visible above it (if these are sensors that are detecting visible radiation). They cannot observe solar radiation being scattered. Interestingly, the sun appears white from the satellite's point of view. This is because the sun emits radiation at all visible wavelengths, and white is the combination of all colors. The sun appears yellow from the surface because again, the radiation gets scattered in the atmosphere.
I have the same question in the textbook the answer is that satellites use sensors to detect changes in the wavelength of light that is reflected from earth surface. They send… this information to computers on Earth, which process into images. Additionally Early satellite communication used radio-transmitters to transfer imagery and data to earth ground stations. Some fixed satellites today use microwave radio relay technology to communicate with the ground which is complementary to that of communication cables. Some of the commercial satellites that capture imagery of the Earth include GeoEye and DigitalGlobe, which provide the imagery used by Google Maps, Google Earth, and others.
Satellites gather data from a satellite image by using electronic devices to collect computer data
You can see some of them if you know when and where to look. A few of them, like the International Space Station, are actually extremely bright (it can, under good conditions,… be noticeably brighter than anything in the sky other than the Sun and Moon).
best to get intouch with military or nasa to find out
