Artificial Satellites

The moon for the tides.

The man-made ones for communications, weather forecasting, GPS, and spying on each other.

The word ‘Communism’ was a french word.

Which is ‘Communist’

A crosslink is when satellites communicate directly with eachother, instead of communicating with a ground station which, in turn, communicates with other satellites. Frequencies that are quickly attenutated in the atmosphere are commonly used, making the link undetectable and unjamable from the ground.

The first artificial satellite in space was called the Sputnik. The Sputnik satellite was launched on the 4th of October, 1957. It belonged to the Soviet Union.

Federal Communications Comission

all correct

Once in space, most satellites obtain their power from the Sun using solar panels. Satellites travelling deep into space often carry additional nuclear power supplies.

LNB satellite dishes are used for telecommunications. The LNB stands for low noise block and it is the part of the dish that collects the lowest frequencies. Your satellite TV distributor should be able to help you get hold of one.

DISH Network satellite dishes must face a certain direction in order to allow the dish to correctly align with the necessary satellite orbitals.

A planet orbits a star (and clears its orbit - new rule - which is why Pluto is now not a planet), while a moon orbits a planet. Someday they will find something that orbits a moon and need a new name.

Some moons are bigger than some planets, or at least were before the latest rule change.

A star that orbits another star is still a star in its own right.

There are objects which are not quite full stars and not quite planets.

Satellites that help defend a nation against attack are called military or defense satellites. These satellites are used for various purposes, including reconnaissance, surveillance, and early warning of missile launches. They play a critical role in gathering intelligence and providing real-time information to support military operations and national security. Additionally, some defense satellites are equipped with technologies for communication and navigation to enhance operational effectiveness.

Satellites typically use a combination of chemical propellants, such as hydrazine or other hypergolic fuels, for propulsion systems that maneuver and maintain their orbits. Some satellites also utilize electric propulsion systems, which may use ionized gases or other materials as fuel for generating thrust. Additionally, certain satellites are equipped with solar panels that convert sunlight into electrical energy, indirectly fueling onboard systems and supporting operations.

The first satellite sent into space was named Sputnik 1. Launched by the Soviet Union on October 4, 1957, it marked the beginning of the space age and the start of the space race between the United States and the USSR. Sputnik 1 transmitted radio signals back to Earth, which could be received by radio operators around the world.

Satellites have most benefited humans in the area of communication. They enable global telecommunications, including television broadcasting, internet access, and mobile phone services, thereby connecting people regardless of geographic barriers. Additionally, satellites play a crucial role in weather forecasting and disaster management, providing real-time data that helps in mitigating the impacts of natural disasters. Overall, their contributions enhance both daily life and emergency preparedness.

No, they do not.

The bhaskara 1 & II satellites were launched in order to study weather and meteorology.

That was Sputnik
