Us humans have never actually been to Mars. We have sent rovers and observers and many other machines but no man has actually visited this mysterious planet. It is believed by many that in the 2030s we will most likely be able to send man to Mars. This would be a very historic event because Mars might have a lot to offer which can lead to many advances in technology.
What we already know
Even though we have not visited Mars, we still have plenty of knowledge on the planet. For example, Mars is the fourth planet from the Sun. Also, it is named after the Roman God of War. In addition, the landmass of Mars and Earth is very similar. It takes Mars 687 Earth days to orbit the Sun. The tallest mountain known in the solar system is on Mars. This is some of the general knowledge that we have about Mars.
There have been 39 Mars Missions and only 16 have actually been successful. Basically, on these missions the scientist and explorers try to find information that they don't already have. Such as, the fact that there might be life on Mars. Nobody has actually discovered this yet. But they have certainly tried. This has been the biggest mystery on Mars, because if there is actually life on this Planet it world change the worlds understanding of everything.
In 2003 NASA sent two rovers on Mars. This has been on going until this day. The rover is still active and NASA is still trying to retrieve unknown information from it. The first spacecraft to land on Mars are called the Viking landers and they landed in the 1970s. This shows how we have been trying to gain knowledge of Mars for many years.
The Future of Mars
Soon we will be able to send man to Mars. And when we do it will be one of the greatest achievements in human history. We will have advances in technology, education, and many other things. We might even find life there which would just be phenomenal because it would open up many opportunities in many different fields for us humans.
There are many planets that have not yet been explored. Such as, Mercury, Uranus, Jupiter etc. But for now the most important to us is Mars because it has so much to offer. Also scientifically speaking, it is not too far away from earth which makes it appealing to us. Hopefully one day we will be able to call Mar our second planet
