None, since satellites don't "land", they orbit. There are 6 landers and rovers on the Martian surface, 2 of which were lost at arrival. NASA reports 3 types of Martian Exploration missions: (1) Fly-by missions: Mariner 3, Mariner 4, Mariner 6, Mariner 7 (2) Orbiter missions (the satellites): Mariner 8, Mariner 9, Viking 1, Viking 2, Mars Observer, Mars Global Surveyor, Mars Climate Orbiter, 2001 Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter (3) Lander and Rover missions: Viking 1 Lander, Viking 2 Lander, Pathfinder Rover, Polar Lander (lost), Deep Space 2 (lost), Spirit Rover, Opportunity Rover, Phoenix Mars Science Laboratory Rover is scheduled to launch in 2011.

The first man made, and Russian (Soviet) satellite was Sputnik launched in 1957.
A satellite is an object in space that is orbiting another object. The moon is a natural satellite of the earth. Man-made satellites orbit the earth just outside the earth atmosphere and used for many purposes such as GPS, telecommunications, weather, and spying to name a few. Satellites are in space
Yes, forensic scientists travel all over the world. Many times they are used in court cases and will travel to testify.
yes
As of September 2021, there are currently 9 active artificial satellites orbiting Mars. These satellites are used for various purposes, including studying the Martian surface, atmosphere, and environment.

Had no effect at all, except for those satellites which were attempting to measure biodiversity.
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon

Uranus has 27 known artificial satellites as of now. These satellites are typically referred to by numbers rather than names.
Venus has no natural satellites. It does have two artificial satellites (space probes). Venus is one of the two planets in our solar system (together with Mercury) that have no moon/natural satellite.
3, Charon, Nix and Hydra.
There is no "Murcury" bu there is a planet Mercury, it has no satellites natural or artificial that remain in orbit around the planet.In 1973 Mariner 10 flew relatively close to Mercury and photographed some of the surface.
Satellites are formed when an object orbits around a larger body, such as a planet. Many satellites are natural, like moons, which formed alongside their parent planets. Artificial satellites, created by humans, are launched into orbit around Earth for various purposes.
Many objects travel around the sun, including planets, dwarf planets, asteroids, comets, and artificial satellites. The sun's gravitational pull keeps these objects in orbit around it, following predictable paths.
