Visit the heart of your red planet to listen to your essential signs


"It's great for us to renew astonishment," said the philosophy, "transient travel has been brought back to youth."

The phrase, which is the beginning of the traditional edition of the classic Ray Bradbury
DistributionArcianas (Minotauro, 1976, is written by Borges), is very suited to wait for the incapable event that will be held today in space. At 17, the local time, after traveling more than six months, will probe Insight NASA land on the surface of Martian to start a two-year mission that will allow us to understand the processes that shape Earth's rocky plans. Solar System (Mars itself, Venus, Mercury and, also, Land), for 4,500 million years ago.

"It is a statistical ship, not rover, as a Viking – explaining the expert Argentinean Miguel San Martín, who, following the direction of four successful rescues of our cosmetic neighbor, is part of the group of consultees that guide the design and testing of this mission – To date, most of the probes and the soldiers focus on the surface and its & Find out if there is life or survival on Mars, this is not enough to be done, but by exploring inside: A & # 39 has no powerful scope. ; a red planet like the Earth, which is fundamental to protecting the sun wind air. "

"Why did you miss it?" It is a mystery, on the other hand, the planet Earth is so appealing that the evidence that has been created is already contaminated, and there, where things are not so happy, can us to monitor it better. It's like to analyze the history of the Earth on Mars and its; understand why they are different, "he says.

Planets were created by the Solar System from a disk of rock, ice and debris screwed around our home star. Mars is the longest most inspected after Earth, but there are no experts on the inside. So far, the many protagols that followed him, in 1971, his NASA's first director, Mariner 9 (we returned to 7300 image of the surface and its two ends, Phobos and Deimos ), atmosphere analysis, recorded as duststorms and life marks (not successful).

The launch – originally planned for 2016-, should be deferred due to a significant reduction in one of the ground modal appliances, the Insight (which responds to "Inside Research that uses Conservative, Exercise and Heat Treatment")) which presents three main instruments.

Seismograph can hear small words of the ground, of fractions of nanometer (billion of meters), due to seamless wavelengths that travel through the planet and thus allow the 3D image of the interior.

There is a drive drumming about five meters of Marsh's umbrella to heat the heat; explore from depth to depth and that's a comment on its & # 39; his activity. And another test will try to accurately verify how much the Martian north pole is "removed" as it does; affecting the sun. These ideas give detailed details of the size of the Mars Mars tree, and it will help verify whether it is dry and what else is heels.

"The most interesting thing about these initiatives is that they give us the opportunity to understand our world," said Diego Bagú, reelist at the National University of La Plata and director of the Planetarium in that town. "This is the first time we are able to contaminate the soil Martian and find out if there are loose movements and what kind of heat flux is there, even though there is no broken crucifixion the present one and, therefore, there is no movement of tectonic pests, geological activity may be due to the effect of meteorites, for example, to analyze how waves will be widespread let us find out what's inside a similar planet. "

Seven minutes of terror

When you reach the destination, the Insight will make one of the essential stages of the mission: to use its solar panels. So, with a height of one meter and 360km in weight, it will reach six meters long (equivalent to half to two thirds of a general length). With these "wings", you can catch the sun rays (at that speed 50% lower than Earth) to energize the tools.

Unlike other surveys, you must use a special robotic arm to slowly add instruments to the surface, which will take about three months.

But to achieve this, it must first save the "access, stretch and land" (EDL) series, which will cause the adrenaline stream to be in the control center because, although do it again, it is completely proven.

"Although the Insight is a copy similar to Phoenix in 2007, and we know that the design is hard, there can always be a mistake in staff," San Martin has arguments, one of those laws. but sometimes something will happen to us. The Mars situation is according to the seasons, as it happens here. The weight can be increased or reduced. When it is not so tight, the way is a & # 39; become more complex. And there may also be dust storms. For this reason, a team from NASA's Laboratory Jet Propulsion Laboratory (JPL) followed the method of trying to reassure the essential level, as in theory; The changes could be altered to make it stronger. of Chothrom, for example, we had a disturbed atmosphere and made small changes to increase success opportunities, "he says.

In fact, at the last minute, the Insight team decided to make the final correction to move the route around 16km.

In addition, there are other obstacles. In order to keep the vessel correctly, it must enter the correct angle: if it is too narrow, it can be burned; If there is, too, that it is too open, it would eliminate the atmosphere and its; holding a bow in the space.

"In about six minutes a half, the module will run from around 20,000 kilometers per hour to eight," Bagu said, "and must access through a window of about 10 km with 20 on either side, a place less than a city. "

Although Mars's air is 100 times aweer than it is on the way, the module must be protected from an anti-earthquake with a thermal shield ready to stand up to 1300 ° C. Then, He will use the parachute and, about 40 seconds before he knows the ground, he goes on both sides, expand his leg and 12 light spiders to reduce the speed and bend on a place called Elysium Planitia, on selected as it is dusty and flat and relatively cheap from rocks.

Marco Polo on Mars

Another innovation of this mission is that the probe travels with two ministers (or
cover) the size of a shoe box estimation, MarCO-A and MarCO-B (which are the mission technicians who call Marco / Polo), who are responsible for offering communications services with their; bottom ground as the module continues. level after the entrance, and they are proof of a concept to be used in searching of purely spatial space.

"In 1999, a ship told us that we were seeing each other on the surface" and we did not hear it again, "said San Martin," so NASA said that all level so we can decide It was not going well and arranged it in later walks. Usually, there is an orbit spacecraft and they make us
relay. The Insight carries both
cover divide it after its arrow and fly in parallel, but from the back While they are in a row, coming ashore, these little soldiers get the signal and go to Earth. And it's a good thing if it works, we do not have to worry that satellite & live & # 39; always on Mars in the right geometry to go ashore. "

In addition to what can be considered, there is no high level of international success in the upper tops, about 40%. "Sometimes these things are likely to be normal," Bagú concludes, "but in fact they are an amazing challenge."
