What can a spy satellite see?
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.
They have an imaging resolution of 5-6 inches, which means they can see something 5 inches or larger on the ground.
How many spy satellites are there?
No one knows how many spy satellites there are in orbit. Here’s what we do know. Humanity has filled space with a staggering number of satellites in the 60-odd years since Sputnik, with the United States Space Surveillance Network currently tracking more than 8,000 man-made orbiting objects.7 Jan 2016

Can satellites see through walls?
NOAA satellites have the capability to provide astounding views of the Earth. But many people want to know if these satellites can see their house, or even through their roofs and walls to the people inside. Satellites differ greatly in the level of detail they can “see”.27 Nov 2017
Can you see satellite from Earth?
Yes, we can see satellites in particular orbits as they pass overhead at night. Viewing is best away from city lights and in cloud-free skies. Eventually the satellite will fly into the Earth’s shadow and then suddenly disappear from view. The International Space Station (ISS) can be very bright.2 Jul 2013

What is the most expensive satellite?
Scientists at the Space Applications Centre in Ahmedabad are also anxious as they go about fabricating unique components for the massive satellite. Together, Indian and American scientists are making what is possibly the world’s most expensive earth imaging satellite that will cost the countries over USD 1.5 billion.25 Jun 2017
How much does a spy satellite cost?
A typical weather satellite carries a price tag of $290 million; a spy satellite might cost an additional $100 million [source: GlobalCom]. Then there’s the expense of maintaining and repairing satellites.
What is the most powerful satellite?
“The heaviest, largest and most powerful satellite ever built by India is successfully launched by Ariane-5 today,” ISRO Chairman K Sivan said moments after the launch. GSAT-11, Sivan said, is going to India’s “richest space asset”.5 Dec 2018
What are spy satellites used for?
To monitor Earth’s climate and weather, weather satellites are used. Spy -or Espionage- satellites are used for intelligence purposes. They are also known as reconnaissance or recon satellites. Communications satellites are helpful in relaying radio signals to various parts of the world.
Who launched the first spy satellite?
The first Corona launch containing a camera was carried out in June 1959 with the cover name Discoverer 4. This was a 750 kilogram satellite launched by a Thor-Agena rocket. The return capsule of the Discoverer 13 mission, which launched August 10, 1960, was successfully recovered the next day.
