The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## How does a satellite get into orbit?

All satellites today get into orbit by riding on a rocket or by riding in the cargo bay of a space shuttle. For most satellite launches, the scheduled launch rocket is aimed straight up at first. This gets the rocket through the thickest part of the atmosphere most quickly and best minimizes fuel consumption.

## Do satellites orbit the Earth or are they stationary?

Stationary Earth orbit Clarke imagined communications satellites as travelling in stationary orbits, where those satellites would travel around the Earth at the same speed the globe is spinning, making them hover stationary over one spot on the Earth’s surface.

## How long does it take for a satellite to complete its orbit?

Many of the satellites in NASA’s Earth Observing System have a nearly polar orbit. In this highly inclined orbit, the satellite moves around the Earth from pole to pole, taking about 99 minutes to complete an orbit. During one half of the orbit, the satellite views the daytime side of the Earth.

## How does the Hubble Space Telescope orbit the Earth?

The Hubble space telescope orbits at an altitude of 380 miles (600 km) or so. But the principle is exactly the same. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!

## How does the weather and TV satellites orbit the Earth?

Weather and TV satellites seem to hover above the equator. These satellites are in geostationary orbits. As one orbits further from the Earth, the speed required to stay in orbit decreases and the time required to complete an orbit increases. A weather satellite monitors the approach of Cyclone Ita in 2014.

## What should the orbital velocity of a satellite be?

The mean orbital velocity of any satellite that needs to reach an LEO should be 7.5km/s (27,000km/h). This value decreases as the altitude increases. The relatively low altitude of satellites in this orbit offers some attractive perks for satellite manufacturers and hobbyists. What is the orbital period of the Low earth orbit?
