Terraforming Mars – The 2020 Rover



As it continues to build on the JPL spacecraft assembly shop High Bay 1 in Pasadena. California, more and more details about the Rover come to the surface and pile up to create the overall picture of one of the most impressive objects that humans have ever made. Below is a more detailed look at the Rover, its instruments, and its historic mission. THE ROVER

For the moment, the machine is simply called Mars Rover. It is based on the same platform as the Curiosity Rover, developed by the Mars Science Laboratory of JPL, but a bit bigger. The Rover is the size of an average car and measures 1

0 feet (3 meters), 9 feet (2.7 meters), and 7 feet (2.2 meters).

Mars 2020 has six wheels that help it navigate terrain of Mars aircraft. His body hides computers and other hardware needed for exploration. The temperature is regulated by means of internal heaters and insulation.

The performance for the rover is provided by a thermoelectric multi-mission radioisotope generator (MMRTG) similar to that used on Curiosity. It converts the heat generated by the natural decay of plutonium-238 into electricity that drives all Rovers' systems. THE EQUIPMENT

The Rover is tasked with a series of missions that have never been performed before. It must be equipped with the latest tools and instruments.

Seven such tools have been selected by NASA for transport to the Red Planet. They were selected from 58 proposed instruments submitted by researchers and engineers worldwide, twice as often as instrument competitions. The seven are listed below. Mastcam-Z is a panoramic and stereo camera used to determine the mineralogy of the Martian surface and to assist in rover operations.

SuperCam is used to provide imaging, chemical composition analysis, and mineralogy. It is able to detect the presence of organic compounds from a distance.

PIXL (Planetary instrument for X-ray lithochemistry) is an X-ray fluorescence spectrometer used for the detection and analysis of chemical elements.

SHERLOC (Scanning Habitable) Environments with Raman & Luminescence for Organics and Chemicals) is the first UV Raman spectrometer to be sent to Mars and may be used to detect organic compounds [19659003] MOXIE (Mars Oxygen ISRU experiment) is the most exciting of all, because it is used to launch man's terraforming efforts on Mars, albeit on a tiny scale: it becomes oxygen from the carbon dioxide of the Martian atmosphere produce – the atmosphere of Mars consists of 96 percent carbon dioxide.

MEDA (Mars Environmental Dynamics Analyzer) is used to measure temperature, wind speed and direction, pressure, relative humidity and dust size and shape

RIMFAX (Radar Imager for Mars & # 39; Underwater Experimentation THE MISSION

The Mars 2020 Rover is the first one to seek long-term goals: It will search for life signs and habitability of the environment, pursue natural resources and hazards and try In addition, it will pick up and store rock samples in canisters placed in strategically important areas to collect and land them in the future, a strategy NASA Depot caching calls.

However, before all this is achieved, the rover will have to reach Mars, and it will leave Earth sometime in July or August 2020 when our planet is next to Mars is. After a few months' drive, it will be on site in February 2021.

To land, the rover will use a parachute, a descent vehicle and an approach maneuver called skycrane. This technique was introduced on the Curiosity to land heavier machines without having to use airbags to soften the landing.

It works like this: After the vehicle accelerates slowly enough thanks to the parachute, the heat shield dissolves. and the descent phase is separated from the rear shell.

With four steerable engines, the descent level slows down the rover. When almost no speed is reached, the rover is detached from the descent stage and tied to a bridle and umbilical cord which lower it to the ground.

The rover's landing site was not selected as NASA still views. Three possible options: Columbia Hills in Gusev Crater, Jezero Crater and NE Syrtis.
