AI Thread Summary
An artificial satellite is set into orbit around the Earth using a rocket, which provides the necessary lift and increases the satellite's azimuthal velocity. The satellite must achieve specific energy and angular momentum to match the desired orbital parameters. After launch, thrusters can be used for further maneuvering to fine-tune the orbit. The selection of specific orbits depends on the satellite's purpose, such as geostationary orbits for communication satellites or a constellation of satellites for GPS. Understanding these mechanics is crucial for successful satellite deployment and operation.

how is an artificial satellite set on an orbit around the earth?

Well, a rocket.

Can you be more specific?

As DaveC mentioned a rocket is used to 1) lift a satellite radially in the gravitational field, and 2) increase it's azimuthal (centrifugal) velocity. The energy and angular momentum of the satellited at the end of the launch trajectory has to match orbital parameters at some tanget to the desired orbit. A satellite can be maneuvered with thrusters, but bascially, it is a matter of achieving the right orbital parameters for given orbit.

See some basic mechanics here -

If the question is intended to be asking how specific orbits are picked, they are based on the purpose of the satellite. Ie, a DirecTV satellite needs to be stationary so that people can point their dishes at it, so they locate the satellites in geostationary orbit. GPS needs several satellites in different locations to give a position, so they use a constellation of around 24 satellites going in different directions to keep a few in view at all times.
 
thnku for all the answers :-)
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
