How many robots are on Mars?
Interestingly, Mars is the only known planet that is fully populated by robots, currently being the home to 16 of them, with more to be expected in the near future. However, just two robots are in operation at the moment. We’re talking about NASA’s Curiosity rover and InSight lander, and four other robots either crash-landed on the surface or got destroyed on entry.
What is Mars made of?
Inside, Mars consists of a dense iron, nickel and sulphur core, surrounded by a softer silicon and an oxygen mantle. The planet’s 50 km-thick crust is made almost entirely of iron, magnesium, aluminium, calcium, and potassium.
Where is Mars?
Just like the other Planets from the Solar System, Mars can be found in space and it’s the fourth planet from the Sun, and also in the Orion-Cygnus arm of the Milky Way. But if you want to be more precise and you’re interested in finding out more about the astronomical coordinates, Mars currently exists at RA 0h 58 m 6s Dec +2 ° 10′ 32′′.
