NASA’s Mars 2020 rover is scheduled to land on the red planet in February 2021, and once it will, it is going to touch down in Jezero Crater, the website of an ancient lake that existed 3.5 billion decades ago. The next generation rover, which will find an official name will build on the achievement of the explorers who arrived before it by collecting the samples of Mars for a long run return to Earth.
But the rover will lay the groundwork for future human exploration by analyzing new technologies.
Even the Mars 2020 rover, which looks nearly identical to the Curiosity rover that landed at 2012, will start its mission investigating Jezero Crater. The six-wheeled rover is equipped with a suite of tools developed to allow it to look for indications of life biosignatures.

NASA believes that Mars was habitable sometime in yesteryear. The planet we see now wasn’t necessarily the case. Mars’ once atmosphere circulates through the years, stripped off by solar particles, leading to the atmosphere we see now.
But so far, we haven’t been able to detect some real signs of ancient life yet. The rover’s team believes that its suite of tools will change that.
The twin Mars Exploration Rovers (Spirit and Opportunity) were tasked with finding evidence of water, plus they were successful right from the gate. Even the Mars Science Laboratory (aka Curiosity) was designed to comprehend habitability and whether the conditions were appropriate for life. Now, the Mars 2020 rover can require that one step further and search for signals of life.

Even the 2020 rover is going to do this by drilling into its surroundings and extracting samples that are going to be returned to Earth at a subsequent time. Returning the samples is a struggle that NASA is starting to tackle. The agency estimates that the earliest it can send a mission s samples are some time around 2027 or 2026.
2020 will be active sciencing the hell from Mars to search for microbial life in addition to testing out technologies that potential human missions will rely upon.
Here’s just how four of these instruments will get the job done.
Terrain Relative Navigation
Landing on Mars is catchy. So far, only around half of the assignments have touched down on the red planet. The 2020 rover is going to be outfitted with a technical attribute to allow it to prevent any potential hazards in the landing zone.
Past assignments, like Curiosity, had a landing spot that was free from debris (like rocks, boulders, etc). However, 2020 will be able to navigate . Since the rover is equipped with a lander vision strategy This ’ s. Pictures are taken by this program through the parachute descent stage. Those pictures are then compared by it .

The computer matches the map (which is made from orbital imagery), to create a guide that can identify landmarks like craters and hills.
Landing sites are then ranked by the system according to security, and may even recognize a hazard. The Mars 2020 mission is going to be the first to check this new system. If all works well, it’ll be utilized such as missions to Mars and the moon.
MOXIE
Astronauts traveling to Mars will need oxygen to breathe and also to use as rocket fuel. Hauling it with the other freight not a workable solution and also is expensive. Even the Mars 2020 rover Has an instrument on called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE for short).
MOXIE will convert carbon dioxide (a gas that’s plentiful on Mars) into the oxygen, which astronauts may use as required. 2020 is outfitted with a prototype version of the gear required for future human missions.
The staff will study the way the experiment performs and use that information to scale the technology to work with on subsequent assignments. But will it work?
MOXIE can only run for a couple hours at one time, and only about per month. (That’s because the system utilizes a full day’s worthiness of rover electricity each time that it runs.) Humans use about 20 g per hour of oxygen and MOXIE can produce about half that.
Also be able to create propellant and in order to encourage a crew of 4-6 astronauts iterations of MOXIE will need to produce about 200 times that amount of oxygen.
MEDA
The Mars Environmental Dynamics Analyzer, aka MEDA, is a suite of sensors developed to study the Martian weather, in addition to dust and radiation and also the way they change over the Martian seasons.

Day and night temperatures around Mars can fluctuate by up to 80 or 90 degrees. MEDA will help scientists monitor quantify radiation in addition to those changes in the outside, to comprehend sunlight heats the air. This heating system causes changes in the Martian wind and can help scientists better understand the Martian water cycle.
Knowing the weather patterns and environment could also result in a better understanding of Mars’s history and shed light on how it transitioned into the temperate, chilly desert now, we see from a habitable planet.
RIMFAX
Even the Mars 2020 rover is going to be outfitted with a ground-penetrating radar instrument: Radar Imager for Mars’ Subsurface Experiment, or RIMFAX.

Scientists hope that RIMAX will help them examine the history of Jezero Crater by peering below the surface. With the instrument’s help, scientists are going to be able to check at subsurface rock and icehockey. So far, only observations are made from the Martian polar snow hockey, but this can boost our comprehension of the entire world ’s internal geology.
Even the Mars 2020 rover is scheduled to launch July of 2020, and will land on the Martian surface six weeks afterwards. If all goes according to plan, then we might be able to answer the query of whether Mars hosted life.
