On the new NASA Mars Mars rover installed wheels

NASA Aerospace Agency Engineerscompleted the installation of the suspension and the installation of six wheels on the Mars-2020 rover, which is planned to land in the Mars Mars crater Dzhezero with a diameter of 45 kilometers in February 2021, according to the Jet Propulsion Laboratory (JPL) in Pasadena, where all the apparatus is being assembled.

Feature of the suspension of the Mars-2020 rover

According to the source, each wheel diameter52.5 centimeters made of aluminum and equipped with 48 lugs to increase the maneuverability of the machine along the not very convenient ground for movement of Mars. Bars and levers of the suspension system for greater strength are made of titanium. Each wheel is equipped with a motor. In addition to this, the front and rear pairs are equipped with a steering system so that the "Mars-2020" can make a rotation of 360 degrees without moving from its place.

“Now it is a real rover. He with the suspension system not only looks like a real rover, but is also ready for integration with the most important components, if you look in the rearview mirror, ”commented one of the managers of the Mars 2020 program at David Grüel from the Jet Propulsion Laboratory.

It is additionally reported that the suspension itselfThe swing type is similar to the one used on the rover “Curiosity”, which is currently working on the surface of the Red Planet. Due to this, the new rover is designed for movement over the surface with an inclination of up to 45 degrees and to develop a staggering speed of 152 meters per hour. However, it is noted that NASA experts will select the route so that the inclination of the surface does not exceed 30 degrees.

In the coming weeks, NASA experts are going to start installing a mechanical arm, a mast with a camera and a soil sampling system.

Without hand-manipulator mars rover lengthis about 3 meters, width - 2.7 meters, and height - 2.2 meters. The mass of the fully equipped apparatus will be 1050 kg, but under the conditions of Martian gravity its weight will seem less.

To launch a new autonomous martian scientificlaboratories in July 2020 from Cape Canaveral will use the Atlas-5 launch vehicle. One of the main objectives of the rover will be to find traces of life on Mars, as well as the study of the geological features of the structure of the Red Planet and the composition of the Martian atmosphere.

Recall that, together with the new Mars rover on the Redthe planet will go a compact helicopter. Scientists from NASA want to check whether it is possible to fly in a discharged Martian atmosphere. You can read more about this venture in one of our previous materials.
