On the surface of Mars there are many steep banks of dried rivers where the remains of plants and animals that lived on the planet can be stored. We can not look for signs of life in such dangerous areas because the current rovers like Curiosity can not climb vertical surfaces. However, the situation could soon change radically as NASA's space agency completed tests on a climber named LEMUR. With his pointed hands he successfully climbed one of the mountains of the United States and found the fossil remains of ancient algae, which means that even the search for life on Mars is in his power.
Tests were carried out in the so-called Death Valley – the hollow between two large mountains in the US state of California. This place is often used by space companies to test rovers, as its stony and dry landscape is very similar to the red planet. For example, the Mars 2020 rover landing system was recently tested in this valley.
New robots from NASA
The LEMUR robot was developed for a long time by the space authority – the first mentions of a robot climber appeared already in 2013. Already at that time he could climb with his hands on vertical surfaces, which held themselves with the help of hundreds of hooks on bumps on the rocks. Thanks to them, in the last test, the robot was able to climb a real rock and find the fossilized remains of algae that had grown 500 million years ago.

You should not be surprised that the algae were found on the rock. The fact is, millions of years ago, there was a huge sea in the Mojave Desert, where the valley is located. It is likely that the robot, with the help of his scientific tools, could even find the remnants of ancient animals by thoroughly examining the rocky surface.
Mars rovers learn to climb mountains
Unfortunately, he will not be able to search for old animals anymore because the LEMUR project is now considered complete. The vehicle is not sent to Mars, but other Rover climbers are already created on its base. One of them is the Robot Iceworm, which can climb on icy rocks, using deep holes.

The robot RoboSimian, on our list of the best lifesavers, can also be used to search for the remains of life on the Martian rocks. It looks like a giant spider that can easily move through rocky terrain with the help of its four legs – engineers can easily teach it how to climb mountains.
