To simply find out more about the Martian planet. Before the Martian probes were launched, much was of course known about Mars- that it had not supported life for hundreds of thousands of years, that the so-called 'canals' were a geographical feature and not artificially made, and so on.
But Scientists from Earth were curious- warranted, the 'canals' were not made by intelligent life, and all evidence supported the theory that Mars is a dead planet. BUT- had it once, maybe, held water? Nobody for a minute imagined that life- even vegetation- existed on Mars, but PERHAPS, it might at one point in the past have had water on it, which MAY have given rise to primitive lichens, and maybe bacterial forms of life. Probes (both orbital and landers) can give the answers to these questions.
And this is indeed what they are currently finding out- the Mars Orbiter suggests that there may indeed be a residue of underground water left on Mars, that appears at some seasons of the year. If any life- even at microscopic level- ever existed there, they would be long dead by now, but their fossilised remains MIGHT exist in ancient rocks, which would indicate that eons ago, Mars may have been closer to the Sun than it is now, which would allow organic life to develop.
The other reason that probes were sent there, was simply to find out what it looked like. Nobody knew what Mars looked like before 1969, when the first probe succesfully landed- and even then, it only transmitted pictures for about 15 seconds. The first truly succesful probe was Mariner 1 in 1976, which broadcast pictures of the Martian surface- it's true that she landed on the South-East of the planet, which is not the best place to go, so all she got was a view of a red desert covered in rocks. Other probes since then have taken pictures of a more interesting geography, with hills, small valleys and variable soil, as well as analysing the content of the atmopshere, but even so the fact remains that Mars cannot, and has not supported, life for many Millenia.
Maybe in Centuries to come, humankind will be able to travel to Mars, and then much further along, even modify it's atmosphere so that people can breathe normally on it without the need of space-suits. But this is a long way off- such things will not happen in the lifetime of anyone alive today! It's quite possible that this will happen ONE day, but not for a VERY long time.
Sending rovers to Mars allows us to gather valuable information about the planet's geology, atmosphere, and potential for supporting life. Rovers help scientists study Mars remotely and pave the way for future manned missions. Additionally, understanding Mars can provide insights into Earth's history and our potential for interplanetary exploration.
A Mars rover sends signals back to Earth through a high-gain antenna that communicates with orbiting satellites around Mars. These satellites then relay the signals to Earth-based receiving stations, which decode and process the data sent by the rover.
whenever nasa or whoever ae able to send people to mars
As of now, no human has been on the planet Mars. NASA and other space agencies are working on plans to send astronauts to Mars in the future, but so far only robotic explorers have landed on the planet.
i dont know :) i think
The two Mars rovers namely opportunity and spirit were shot to Mars in 1997 and 2006 respectively. Their aim was to send signals from mars back to earth to give researchers a better understanding of what goes on in Mars.
they take pics and look for life
That's already happened a couple of times. The Mars Rovers have brought back fascinating stuff. You can check it out on various space program sites, or government agency sites like the U.S.G.S. (United States Geological Survey). They have great pictures.
It doesn't. It radios its data back to Earth. there is no need for the actual rover to come back. Nothing should be brought back from Mars unless it is proven lifeless, as Martian life may be dangerous to Earth life, like us!

First of all, Mars is a lot closer to Earth than Mercury. The other reason is that since it is further away from the sun, it is not as hot as mercury which makes it easier to send rovers.
Yes, NASA has sent several rovers to Mars, such as the Curiosity and Perseverance rovers, to study the planet's surface and gather data. Additionally, NASA has plans to send crewed missions to Mars in the future as part of its Mars exploration program.

No human has stood on Mars yet. All Mars exploration has been done using rovers and orbiters. NASA aims to send humans to Mars in the 2030s as part of its Artemis program.
Zero. Nobody walks on mars, and nobody has ever walked on mars.
I think rovers send info from a radar dish or somthing really complicated.
Astronauts have sent robots to explore the following planets: Mars, Venus, and the Moon. These robots, such as rovers and landers, have been used to gather data and conduct experiments to further our understanding of these celestial bodies.
