What will make rover "Mars 2020" with their hands?
Space agency NASA has long been trying to find signs of life on Mars. I think she has it does not matter, it exists now or sway on the planet millions of years ago, because even detect barely noticeable traces of extraterrestrial microbes would be a sensational discovery. In July of the following year in search of the Martians leave the unit under the name "Mars 2020", equipped with a two-meter robotic arm. It is one of the main instruments of the rover, but what it can do?
First, let's remind that the new rover is based on "Kyuriositi" system, which examines the planet's surface to this day as much as in 2012. He, too, is equipped with a robotic limb, but the "Mars 2020" will receive an improved version with a more precise scientific instruments, drill to drill the surface of the planet and the quality of the camera. More precisely, the new rover is all already received - the hand was attached to the body of the device at the end of June 2019.
The robotic arm Mars 2020
"Mars 2020" will fly to the Red Planet about a year and, according to the scientists, it will face its atmosphere will fall to the surface in February 2021. Place of work will be the 45-kilometer crater called Jezero, in the territory of which millions of years ago a river. By means of its 2, 1-meter-hand weight 40 kg, it will prey species, which can leave traces of ancient organisms. The study of rocks also tells a lot about the formation of the planet and its structure.
The structure of the rover's arm
To remove soil samples from the interior of the planet will be used rig. The collected materials will be carefully examined in the internal laboratory of the device, but some of them will be moved inside the container to someday they could be sent back to Earth for study by these researchers. The study will also play a big role SuperCam camera capable of analyzing soil samples from a distance, to do color photos, and record sounds.
By the way, Insight apparatus also has a drilling rig, but recently it was stuck
At this point the assembly "Mars 2020" machine manufactured in a sterile room, located at the Jet Propulsion Laboratory of NASA. Recently in the room there was a webcam, which allows anyone to follow the progress of the build of the new rover. Engineers have already demonstrated the movement of the hand - accelerated video and lasts only a few seconds, but the creators of the rover made sure that no part of the body does not block the movement of the limbs.
Also on the rover were installed wheel diameter 52, 5 centimeters. The unit can be rotated 360 degrees without moving from the spot, because the steering system, and affects the front and the rear pair of wheels. It is hoped that the rover can reach the speed of 152 meters per hour, and the design will allow it to move up and down the slopes with a slope greater than 45 degrees. It is hoped that the device will not have problems with the wheels, as in "Kyuriositi".
