It depends on the type of satellite, and whether you mean a particular ONE satellite or all of the satellites in aggregate.
You can do a lot with weather satellites, like looking into hurricanes. You can think of a KH satellite as a gigantic orbiting digital camera with an incredibly huge lens on it. Commercial and security satellites do the same. Satellites, camera drones, and other cameras lofted in planes and helicopters all get nadir and oblique images. From left to right and lowest to highest resolution: NOAA/NASA Suomi NPP (375m / pixel), Landsat-8 (15m / pixel) and Worldview-3 (<1 m / pixel).

A satellite is an object in space that orbits or circles around a bigger object.
Hurricanes only affect things in the atmosphere. Some take pictures of our planet.
Today, the Landsat program is not the only one to take satellite images of Earth.
Pretty much continuously!
These two things are, however, very closely related, because the job a satellite does usually determines both how far away from Earth it needs to be, how fast it has to move, and the orbit it has to follow.
We think of light as visible light, UV, infrared, radio, etc. What do satellites do for us? Today they … Some take pictures of other planets, the sun, black holes, dark matter or faraway galaxies. Man-made satellites are machines made by people. Some take pictures of other planets, the sun and other objects. Optical image reconnaissance satellites use a charge coupled device (CCD) to gather images that make up a digital photograph for transmission back to Earth from an altitude of about 200 miles.
Note that the pictures of Earth do have satellites in them; however, they’re too tiny to be resolved in the image. Satellites are outside the atmosphere. There are thousands of man-made satellites. These pictures help scientists better understand the solar system and universe. To take pictures of the whole Earth, you have to be very far away.
We tend to group satellites either according to the jobs they do or the orbits they follow. Satellites are very far away from the Earth's surface.
These machines are launched into space and orbit Earth or another body in space. They see a large part of the Earth in one satellite image. Take pictures of the hurricane. With modern transmission technology the number of pictures (or video) that can be taken, sent or streamed is essentially unlimited. The Deep Space Climate Observatory (DSCOVR) satellite is on its way to do something epic.
NOAA satellites employ a wide swath to capture a large area in one image. Most images of our planet are only a few thousand pixels in diameter; so unless an object is of the order of a kilometer or more (which no object in the vicinity of the planet is), it would only be a fraction of a pixel, and thus invisible in the image. Odenwald says that inspired him to launch the Satellite Streak Watcher project and ask citizen scientists all over the world to take pictures of these satellites with their cellphones.
Satellites take satellite pictures of the cloud cover, I don't think any other measurements are taken by satellites.
Science Fair Projects - How satellites take pictures. NASA’s Landsat series of satellites have consistently orbited and captured images of the Earth since the program launched in 1972.
Even as late as the mid-80s, reconnaissance satellites delivered their pictures back to the Earth using fragile film canisters mounted on parachutes and picked up by planes in mid-air. It depends on what they want an image of.
Pictures taken during poor weather are likely to be filtered out.
Side by side you can see the effect of the resolution of each of the satellites.
