Why do we keep going back to Mars?


Mars has been humanity for centuries, and dream of the potential to lie on the dust-orange surface. As the growth of our tapes has been developed, so our photo on Red Planet, although scientists' explanations have not been modified; These details are never right (see: canals Mars). A first intention to & # 39; Mars shows close, Mariner 4, and inserts to her; home a number of shade scenes, but the following initiatives – the ones that were successful; The fullest extent ups up 50% for a spacecraft linked by Mars – to paint a clearer picture of dust dust, burns today.

Recently, scientists have found evidence of an older, warmer and wetter planet for a planet that could host a life similar to Earth, so the search for life to continue, although it is now going to the last. And its planet has fewer material from the tectonic movement than Earth, so it can tell scientists about how to use the Earth. creating the solar system.

NASA's InSight Mars, which will be installed on Monday (November 26), will grow deeper in the surface of the planet any preceding resolution, learn about it inside its & # 39 ; planet. InSight is less than many of the rovers and the actions that are going on, but & # 39; It is the latest thing in a long series of robotic supporters to explore our planetary neighbor.

"Mars is a fascinating natural laboratory next door to Earth," said Lori Glaze, NASA's planetary NASA planetary actor director, when he spoke to InSight on November 21. "We want to understand how We include a diversity of rocky plans in our solar system – they are all very different, each of which is unique in its own way, and try to understand how they came to so different a very important issue. "

In addition – the weakness rate despite – the planet is easy enough to be converted and it is less likely that our device melts the Vèus or Surprising.

Mars geology gives a lot of evidence of water, and Glaze added, so "it could be a place where life could be very early in the history of Mars. And, indeed, trying to understand how life is spread over our bottom is a system one of our key issues. "

The ground, Mars and the other rocky planets in our solar system are built together from dusty dust around a young sun, grow warmer and warmer as a material added and pour into your body with sticks and a special shell. But we are not well known about that period in the history of the planets.

"Air Mars, that structure has been retained over the last 4.5 billion years, but on Earth, where we can easily read it, all of these structures are surrounded by teitonean plates, with wood splitting, so there is evidence that early sweeping processes have been removed on Earth, "said Bruce Banerdt, chief inspector of the InSight mission and researcher at the NAS Propulsion Laboratory of NASA in California during the preparation.

So, just like forest survey – a & # 39; leaving this creation process – telling researchers about the earliest days of the solar system, and # 39; The structure of Mars structure is measured by measurement of planetary temperatures and marsquakes can inform scientists of the next stage in the development of a planet.

And to get more information about the current situation of Mars, researchers can also help with & # 39; understand how it would appear in the past. [Why We’re Obsessed with Mars]

"Mars is a very special place in our solar system because one of the few real ideas we've ever had," Briony Horgan, a scientist planet from Purdue University who is focus on geological history of the moon and Mars, to Space.com. "Today, this cold, unhealthy atmosphere is very calm … low pressure, all radiators that swim the surface. But when we are & # 39 ; look at the geological map of Mars, we see many things like dry river channels, dry lake lochs and sediments of lochs; we see minerals across their planet that can only to be in the presence of water.

Mars 3 or 4 billion years ago may look very similar to Earth early, Horgan said, and long ago. Since we have drained its planet, plateauettes and other processes on excavating rocks from that time, Mars is a offer another opportunity to see them.

"Geology Mars has just been so active on the scale of Earth that the rocks are 4 billion years ago just to sit on the surface," said Horgan. "They are not arrested, they are not buried, they are not eroded – they're just sitting there, especially waiting for us to & Look at them and try to understand what these older 4 billion are likely to look like old scenes, and they supported your life. "

Horgan is a scientist on the NASA's rover Mars 2020 mission, on which the organization's site was set up by the group named on November 19. The rover Mars 2020 is a " Follow in the steps of at least two Viking clans in 1976, which landed on the Red Planet for searching life according to scientists & their best understanding of situations; planet, and the rover Curiosity, who disappeared in 2012 to investigate a living place.

How do our ideas on the plan and # Growing, our search engines are also our life, Horgan said – after the Spirit and Opportunities have been presenting evidence of water, he has noticed scientifically enough science to try to find creativity or other evidence of residence near these old water beds. Mars 2020 will build on the ongoing Curiosity work by bringing it even more widespread survey tools, for example, legends in rock, and # 39; Look for microfossils or textures that propose ancient biology. Scientists do not know if water was often flush on the surface, or if it was mostly frozen with occasional melting due to volcanic activity.

"Some of the instruments on 2020 are going to hell into more detailed information on the rocks, the kind of things we can not see with our existing instruments, Currently, and finally installing samples, if they were brought back Earth, which gives us long-term basic information, "said John Grant, a geologist of the Smithsonian Institute that has been on the science teams for Spiritual Spirits and Opportunity, Information and Orbiter Report Mars. He also collaborated on the process for choosing the Mars 2020 website.

"InSight is a very important part of that, because none of these are [NASA’s previous missions] indeed – express in particular – scroll down under the surface of the planet's development and an understanding of how the planet has spread over time, "said Grant.

"If we know something about the internal structure and the development, we can say something about how long it has been active, whether it is or is not as active as it is today, and everyone has an impact on the changing conditions … as it relates to things like a living and a life that has gone wrong, "he said to Space.com. So, although InSight does not just deal with Mars's life, "it's all interlaced," he said.

And, indeed, with NASA development plans to finally send people to Mars, anything that we will help will prepare for that time.

"Yes, we're going back to the moon, but we also have the way to Mars, and science [helps] make sure that we understand the resources, and to Examining that we understand living contexts and we are experiencing; understand what to be investigated, "said Thomas Zurbuchen, associate administrator led by NASA science mission, when announced on the Mars 2020 website.

"No, I'll argue, an extra argument as well as why Mars is so inspiring," he said. "We will not go anywhere else at any time as soon as our soil plants for all obvious things. Mars is a prominent place after its moon goes back and expand our presence to a deeper and deeper place. "

Why do we keep going to Mars? To learn about our solar system, learn the origins of Earth, to find life and just to learn about a neighbor before visiting.

"Science gives us an understanding and allows us to take people to Mars," said Glaze during the preparation. "Our biggest research, better we understand that environment, the best arrangements we are to send people to Mars during this time future. "
