Called the Roman god of war, Mars is not very kind to the visitors

NASA's Mariner 4 made the first successful flyover of the red planet in 1965 by sending 21 photos.

Mariner 9 made it in orbit around Mars and shot back more than 7,000 photos.

And NASA's Vikings 1 and 2 not only launched a spacecraft in orbit around Mars in 1976, but also on the surface. Viking couples were the first successful landings on Mars from planet Earth.

The 90s of the last century were not as good for NASA. A humiliating English-metric vibration for reversing was doomed to a Mars observer in 1993. Another American orbit was later lost, as well as ground and two companion probes designed to penetrate the surface.

Despite decades of experience, Russia, in particular, was lucky on Mars.

Then the Soviet Union was the first to try to cross Mars in 1960. The spacecraft never reached the Earth's orbit. After further failures at launch and unfortunate flights, the tips eventually received a pair of spacecraft in orbit on Mars in 1971 and received real data. But the companions' companions were quite bust.

So it was for the Russians and the Russians in their last experience with China in 2011. The bleak purpose was to land a Mars Phobos spacecraft to collect and return samples and put a second weapon in orbit around Mars. Nor did he get out of Earth's orbit.

Europe was also bitten by snakes on Mars, as well as Japan.

While the European Space Agency has satellites operating around Mars, both attempts to land are floppils. Only two years ago his land-based ship struck the surface so quickly that he dug a crater. The only Japanese space planet Mars, launched in 1998, has not made orbit.

Meanwhile, India has operated a satellite around Mars for four years – the first and only shot of the red planet.

There is a great European presence in NASA's InSight. Germany is responsible for a mechanical mall designed to expel 5 meters to the surface of Mars to take underground heat measurements while France directs the earthquake monitoring seismometer.

On the surface, Curiosity is the only thing that works on Mars. Currently in orbit: US Odyssey from 2001, Mars Express in Europe (2003), US Mars Reconnaissance Orbiter (2006), US Maven (2014), Mangalyan (2014) in India and European Trace Gas Orbiter (2016 ).
