Weather reports were not accurate. Long distance communication required cables and microwave relay towers. There was no GPS navigation systems. Land was mapped slowly and expensively.
A satellite is a body orbiting another like a planet or moon. A natural satelite is not man-made. The moon and other bodies were called this before the artificial, or man-made satellites were ever made like the ISS.
There are no known satellites of Mercury.
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.
Triangulation of satellites requires three satellites that bank of one another simultaneously.
Yes but they are called natural satellites
Satellites increased the speed of global communications.

is there life other than ours? are there any other earth like planets in the universe
Satellites have a typical operational lifespan of 5 to 15 years, after which their fuel is exhausted or their components degrade. However, some satellites have lasted much longer through efficient management of resources. When a satellite reaches the end of its life, it may be moved to a "graveyard" orbit to reduce the chances of collision with other operational satellites.
Satellite. Satellites can be natural, like the Moon, or artificial like GPS satellites.
What was life like before Albert Einstein moved to America
Natural satellites are things like our own moon that orbit a planet.In our solar system there are 173 natural satellites that we know of.
They improve communications.
Applications satellites, like weather satellites, communications satellites (TV, Cell phone, internet), military observation birds, reconnaissance satellites and other "useful" things predominate. Purely scientific satellites such as the Hubble Space Telescope are in the minority.

It was estimated some of the Vanguard satellites- which looked like little influence mines- might have a natural life span of some 400 years but not in an active role.
