NASA will send its roaming destiny to a Martian delta to look for signs of old life


NASA scientists chose to plan their next explorer on Mars in 2020 – on the Red Planet – into an area that could be an old river delta. The spacecraft will aim to touch the Jezero Crater, a habitable space billions of years ago. NASA drew special attention to investigate this point; One day, samples collected by rover can be returned to the World for study.

This new rover is the last of NASA's 2012 debut in Mars. This robot explores an area known as the Gale Crater in Mars, which was a wetting point in the past much more than it has been today. I've learned a lot about a little slice of Mars in the last six years of curiosity. He found organic matter in the Mars soil and detected methane – a gas that lived here in the world. However, with the new Mars 2020 explorer, NASA is finally hoping to answer a long burning question: did biological life really survive on the surface of Mars?

To solve this, Mars 2020 was designed to be the first step of what is known as the Mars example return mission. In the Jezero Crater, the robot will reveal evidence of past life on Mars and reveal rock samples that can store these materials on surface caches. Later, at an unknown date, NASA will launch a second mission to Red Planet to gather samples of Mars 2020 and bring them back to Earth. Thus, we can examine these Mars rocks in our own advanced laboratories to understand what the old Mars looks like.

A Mars example return mission is currently one of the top priorities of the planet science community. Also, the withdrawal is an incredibly difficult task. To get samples from Mars, NASA will need a set of sophisticated technologies, including a rocket that can stand on the surface of the Red Planet. In this way, the samples will be able to escape the gravity of Mars and have enough energy to travel back to our planet in space.

Until now, NASA has no plans to figure out how to make Mars 2020 samples from Mars, but the space agency hopes to launch this follow-up mission in the late 2020s, and this is going back to Earth a little earlier. 2030 & # 39; s in. "I don't have any updates today," said Thomas Zurbuchen, managing director of NASA's Science Mission. ”Business continues.“

But first, Mars 2020 will choose the most compelling examples for further research on the roaming. To find the perfect place for this, NASA experts and other planetary scientists met in a series of four workshops over the past four years. They managed to narrow the landing zone by more than 60 possible options. The Jezero Crater was one of the four finalists in the northern hemisphere of the planet. And ultimately because of the potential for inclusion of ancient biosignates – because of the signs of life long – won.

Perhaps the most attractive aspect of the Jezero Crater was the fact that it once housed the flowing waters. An asteroid impact may have carved out the site and created a crater of 28 miles wide and 1,600 feet deep. Scientists believe that the crater was filled with water 3.5 to 3.9 billion years ago. There is a delta within the crater, a delta that tells the researchers that water flows into the lake, precipitates and other materials are precipitated along the way. As the lakes are quite habitable in the world, Jezero makes the Crater an attractive option. And the flowing water also increases the likelihood that the microbes or other life will be transported to the area and trapped. Ken Farley, a project expert at NASA's Jet Propulsion Laboratory in 2020, said, "Delta has been stored for billions of years since the existence of this lake, and is a good place for proof of life later protected." . Press conference.

Jezero Crater is also home to interesting and diverse rocks that make it a great place to explore from a geological point of view. The most exciting one is thought to have at least five different rock types known as carbonate. This type of rock consists of interactions between water, rocks and gases in atmospheres such as carbon dioxide. Carbonates could hold clues as to what the ancient Mars atmosphere was billions of years ago. And it can also be another place where microbes develop – separate from the lake.

While Jezero Crater has some great features for research, the area is not the best place to descend a spacecraft. There are many rocks and rocks, cliffs and depressions in the area, which will be a challenge for a vehicle that needs to be touched gently. The Mars 2020 mobile vehicle, however, includes a mechanism such as a rope known as a sky-crane, which will be equipped with a sophisticated landing routine such as its predecessor, and will slowly lower the ground into the vehicle. Engineers have also been able to refine their landing systems in recent years, so that the spacecraft can avoid fluctuating areas, according to NASA.

There are too many improvements to be made to prepare the Mars 2020 navigator for the launch. In July of 2020, there was a landing in 2020 with a robot to move on top of an Atlas V rocket. Meanwhile, NASA focuses on landing. another the spacecraft on Mars this week – a robot called InSight that will sit on the surface of the Red Planet and explore the world's interior. InSight has traveled to Mars since its launch in May and is scheduled to go ashore on Monday (November 26th).
