They send data about 1-22,000 miles. The moon isn't even millions of miles away, it's about 250,000 miles away, or 1/4 million miles.
They send information by way of radiation, usually radio waves. Radiation is light, most "light" is invisible to us, heat and light are the only kinds we can sense naturally. Radio waves are sent out in highly complex bursts which computers on earth translate into 1s and 0s, which is what computers use for information.
An unmanned spaceship can transmit pictures to Earth using onboard cameras that capture images or data, integrated communication systems, and antennas that send signals back to Earth. The spaceship typically communicates with ground stations or satellites in space to relay the pictures or data to Earth.
Pictures of Earth are taken by satellites, spacecraft, and astronauts in space. These devices use cameras and imaging sensors to capture images of Earth from different altitudes and perspectives. The images are then transmitted back to Earth for analysis and use in various applications, such as weather forecasting, environmental monitoring, and mapping.
Satellite pictures of Earth and other planets are captured by cameras or sensors onboard spacecraft and satellites in orbit. These images are then transmitted back to Earth using radio waves or other communication methods. Data is received by ground stations that can decode and process the information to create the images we see.
The earth is a spherical shape, and they food this out because in the late 20th century, artificial satellites sent back pictures confirming the earths round shape. Much earlier, Aristotle suspected earth was a sphere by observing that earth cast a curves shadow on the moon during an eclipse.
In space, there are satellites that take pictures of the weather all around the world. Then they send the photos back to NASA. At NASA, the scientists study the pictures and they can figure out if a storm is coming up.
Satellites take pictures and accumulate other information into the computer. They analyze the data and send it back to weather stations on earth.
One can find pictures of earth satellites on the NASA Visible Earth online website. NASA Visible Earth is a catalog of NASA images of our home planet, earth. The website "Geology" is where one can also find pictures of earth satellites.
Satellites use the earth's orbit and the earth's gravity to take pictures. The satellites orbit the earth in the same direction that the earth spins. That way the satellites never have to move against the earth's movement to take pictures. There are two kinds of satellites; ones that take pictures that are designed for taking pictures, and ones that are designed for spying. The ones that are designed for spying can magnify what are seeing on earth. Otherwise, the two kinds of satellites work the same way.

A satellite is orbiting the Earth and taking pictures of it. Satellites are equipped with cameras that capture images of Earth's surface for various purposes, such as weather monitoring, environmental analysis, and mapping.
Google Earth is made of pictures taken from satellites. If your house is new or has been renovated, the satellites may not have taken a picture of it yet.
An unmanned spaceship can transmit pictures to Earth using onboard cameras that capture images or data, integrated communication systems, and antennas that send signals back to Earth. The spaceship typically communicates with ground stations or satellites in space to relay the pictures or data to Earth.
We send satellites and space probes equipped with cameras into space. The satellites and probes can be sent commands via radio waves, and the equipment then sends back digital photographs via radio as well.
They are called maps
Plenty. Just look Google Earth for the pictures of everything.
Google satellites are closer to the Earth than the NASA satellites are to the moon. And those pictures are pretty good.
Communications satellites, launched in the 1960's. There were 2 Echo satellites, which were passive (the signal would bounce back to earth like a mirror). The Telstar satellites were active, meaning that the signal was retransmitted back to earth.
