How does SATCOM work?
An earth terminal transmits data up to the satellite. The satellite can then either shoot it right back down in its footprint to another earth station where the data was meant to go. It can relay it directly to any amount of other satellites and then down to the other earth terminal you were wanting to talk to. Or it can go up to the satellite, back down to another terminal, up to another satellite, and then down to where you wanted to "talk" to.
How does gravity affect the launch and travel of a satellite?
It has to get up to 7km a second to get out of earth's orbit, then it orbits around earth.
How far away is the farthest satellite?
The earth is a planet. An earth satellite is an artificial satellite that orbits the earth A geostationary satellite is an earth satellite that orbits at a height (approximately 22,000 miles) precisely determined to ensure that the satellite remains over the same spot on the earth's surface at all times, thus appearing from the earth to be stationary in the sky.
How does a Landsat satellite differentiate between objects on Earth's surface?
Features on Earth radiate warmth at different frequencies, which show up as different colors on Landsat images.
What is the ROSAT satellite?
ROSAT is a German satellite launched in 1990. It was used for research on black holes and neutron stars. It was supposed to be in space for 18 months, but since it was successful it stayed there for 8 more years. In 1999 communication of ROSAT satellite with Earth was lost. Scientists predict that it will hit the Earth sometimes between October 21 and October 24, 2011. Parts of the satellite will burn up during the re-entry in atmosphere, but at least 30 fragments, weighing 1.87 tons could crush into Earth with a speed up to 280 mph.
Is there any satellite or robots that have explored neptune close up?
have any satellite or robots look-up close to neptune
What robot or satellite explored Saturn up close?
cassinni
What is the name of the satellite or robot that explored Earth close up?
The satellite or robot that explored Earth close up is the Earth Observing System (EOS) by NASA. These satellites collect data on various aspects of Earth, such as weather patterns, climate changes, and environmental phenomena.
Have robots or satellite explored mars close up?
yes but what kind
What are the names of any satellite's or robots that have explored Neptune close up?
Voyager 2 is the only probe.
Have any satellites explored earth up close?
Plenty. Just look Google Earth for the pictures of everything.
From earth one satellite appears to overtake another the faster satellite is?
The faster satellite appears to overtake another satellite when observed from Earth. This is because the faster satellite covers a greater distance in the same amount of time, causing it to catch up to and pass the slower satellite.
Why does satellite gets hot?
Most Likely the satellite gets hot form coming in close proximity with the earth's atmosphere, skipping along it, therefore causing friction with it and heating it up.
Have any satelites or robots explored uranus up close?
no
What robots have explored Saturn up close?
The "Cassini" in 2004.
What satellites or robots have explored mercury close up?
none
What happens as the satellite get closer to the earth?
As a satellite gets closer to Earth, the force of gravity acting on it becomes stronger. This can result in an increase in speed and a change in the satellite's orbit. Ultimately, if the satellite gets too close, it may enter the Earth's atmosphere and burn up upon reentry.
