Artificial Satellites

The force of gravity is responsible for changing the velocity of a satellite, thus affecting its path or trajectory in space. This force influences the satellite's speed and direction, causing it to move in an elliptical orbit around a larger body such as a planet or a star.

Satellites may fall out of the sky because they get too close to Earth. In that case, Earth overwhelmed the power of the satellite's propelling system and slowly but surely dragged the satellite into the Earth's atmosphere.

They are usually distinguished according to the size of the repeats:

Microsatellites, also termed Short tandem repeats (STRs) consist of tracts of repeats of 1-7bp, and minisatellites also called (VNTR) usually contain repeats of longer length (100-several hundred bp)

Minisatellites can be found in tandem arrays, but the majority are interspersed in the genome. Whilst microsatellites are found mostly in tandem repeats.

The most likely factor that would cause a communications satellite orbiting Earth to return to Earth from its orbit would be atmospheric drag. As the satellite moves through the Earth's atmosphere, it experiences friction with air molecules which can slow it down and cause its orbit to decay, eventually leading to re-entry into Earth's atmosphere.

That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.

The launch of Sputnik by the Soviets in 1957 sparked fear in the Americans about potential Soviet technological superiority and military capabilities. This led to increased funding for science and education, the establishment of NASA, and the eventual space race between the two countries.

The Sputnik satellite had a total weight of about 184 pounds (83.6 kilograms).

Sputnik was the first artificial Earth satellite, sent into orbit by Russia. The long-retired Sputnik rocket that was used to lift off the Sputnik 1, 2, and 3 payloads was an unmanned orbital carrier rocket (8K71PS) from the R-7 family of rockets, similar to America's (also retired) Vanguard and Juno I rockets.

A satellite is an object that orbits around a larger object in space. Satellites can be natural, like moons orbiting planets, or artificial, like those designed by humans for communication, weather forecasting, and navigation purposes. These artificial satellites are launched into space and then maintained in orbit by the gravitational pull of the Earth.

A space satellite typically looks like a metallic cylinder or box with solar panels attached. It can vary in size from small CubeSats to larger, more complex satellites. They are designed to withstand the harsh conditions of outer space while carrying out their specific functions, such as communication, Earth observation, or scientific research.

Satellites are powered by different types of fuels depending on their design and purpose. Some satellites use chemical rocket propulsion with fuels like hydrazine or a mix of hydrazine and nitrogen tetroxide. Others may use electric propulsion systems powered by xenon gas. The choice of fuel depends on factors such as mission duration, maneuverability requirements, and efficiency.

The Rohini satellite was launched on May 31, 1980. It was launched by the Indian Space Research Organization (ISRO) from the Sriharikota Range in Andhra Pradesh, India.

As of 2021, the company with the most satellites in orbit is SpaceX, with its Starlink constellation for providing global broadband internet coverage. They have launched over 1,600 satellites.

The largest and coldest satellite in our solar system is Saturn's moon Titan. It has a thick atmosphere primarily composed of nitrogen and is known for its icy surface, with temperatures dropping as low as -290 degrees Fahrenheit (-179 degrees Celsius).

Low Earth Orbit (LEO): Earth observation, remote sensing, satellite communication. Medium Earth Orbit (MEO): Global positioning system (GPS). Geostationary Orbit (GEO): Weather monitoring, telecommunications, television broadcasting.

1. Design the satellite and choose a launch vehicle.
2. Prepare the satellite for launch by testing and integrating it with the launch vehicle.
3. Schedule a launch opportunity with a spaceport.
4. Conduct a pre-launch check to ensure all systems are functioning properly.
5. Launch the satellite into its designated orbit.

A polar orbit would allow a satellite to view any point on the Earth's surface from (nearly) directly overhead. The times for a given location would depend on the altitude and the speed of the orbit. The advantages are a minimal angle to the specific point below the satellite's path, which would benefit direct obsevation (as with military "spy satellites"). Among the disadvantages is increased fuel cost to reach the orbit, and increased shielding in some orbits due to the polar radiation belts around the Earth.

The Sport Satellite has a different hood unique to the sport satellite (not a roadrunner hood) the dash says sport satellite as well. The sport satellites are a little more rare and are worth more then a plain satellite.

Yes, it is possible to see the Sputnik satellite from Massachusetts. Sputnik was the first artificial satellite launched by the Soviet Union in 1957 and could be seen in the night sky as a bright moving object.

Yes, the first artificial object put in space was the Soviet satellite Sputnik 1, launched on October 4, 1957. It marked the beginning of the space age and the start of human exploration beyond Earth.

Explorer 1 was launched to become the first satellite of the United States. It was part of the US effort to explore space and was a response to the successful launch of the Soviet satellite Sputnik. Additionally, Explorer 1 carried scientific instruments to study cosmic rays and radiation in space.

Uranus has 27 known satellites and it has a dim set of rings. The 5 major satellites of Uranus are Miranda, Ariel, Umbriel, Titania and Oberon.

Satellites equipped with synthetic aperture radar (SAR) sensors can penetrate clouds and smoke by emitting their own microwave signals that can pass through these obstacles and reflect off of the Earth's surface. By analyzing the return signal, satellites can create images of the ground beneath the clouds or smoke. Additionally, satellites with thermal infrared sensors can detect temperature differences caused by fires or heat sources even through clouds or smoke.

orbit

The first man-made object to successfully be placed in Earth orbit was dubbed "Sputnik".

It was launched from the Baikonur Cosmodrome in Kazakhstan ... part of the USSR at
