NASA Insight probe reached Mars and sent the first image – 11/26/2018



NASA did it again. Six years after the "landing" of the Curiosity rover, Put an object on the red planet. This Tuesday, the InSight investigation, after seven months of research and development, succeeded in overcoming the seven-month area and the "seven-minute terror" by distributing its equipment and delivering the first message after a few minutes of support. Three legs on Mars, 55 million kilometers on Earth. And although this is simple for existing technology, managed to reach only 40% of sent tasks successfully.

The main complication of heavy probes trying to descend into Mars sand is the subtle atmosphere – the pressure on the surface does not reach 1% of the terrestrial – and the ship has little resistance when testing the vessel's entrance. Engineers to slow down before they hit Synchronized thermal shields, paragliders and rocketsin less than seven minutes.

Seven minutes before this 17th Monday (Argentina time), InSight entered the atmosphere of Mars in an oblique manner 12 degrees from the planet. If he had more, he would be less burned, lost in space, and eventually lost. The probe is about 20,000 km / h, which is three to four times faster than a shotgun bullet. The thermal protector was heated to a temperature of 1,500 ° C, which is the temperature of the surface of the sun.

Selected place to go down Elysium Plain: Because of its few geographical features, a smooth and dusty extension called the ğü largest parking spot in Mars “was chosen from 22 possibilities, 600 km away from the point where it fell, to minimize the risk of landing. Wonder.

The process was perfect: the activation of the parachute, the placement of the legs and speed up from 19,800 km / h in just seven minutes to 8 km / h. A series of "terrorism" where all tasks can fail with a small error.

. I wish I was here!!, The message was tweeted by the official account of the catheter to announce the first image he took while approaching the surface of Mars.

"My first photo # Marte. My films have not yet been removed, but I should have given them my first look at my new home," he said, adding that the space agency feasts were underway at the Propulsion Laboratory's control center. By NASA Jet in Pasadena, California.

"I'm here, with this safe descent, you'll feel Mars, and soon you'll know your heart. I am home"He then broadcast live and released the InSight module from his journey through the world through this social network.

Technical arrangements were made until the last moment. "Two hours before reaching the atmosphere, the entry, landing and landing gear (EDL) reported some final touches to the algorithm that directs the spacecraft to the surface," NASA said.

As Earth and Mars formed in a similar way, NASA expects to help understand why they are so different. This evolution on our planet was concealed by millions of years of earthquakes and the movement of molten rocks in the mantle, while Mars was less geologically active than it could have been before.

The InSight module will collect data from three instruments before landing on a $ 993 million landing: Seismic fogging system (SEIS), RISE device (to locate the probe when rotating around its axis while Mars is rotating); and HP3 heat flow sensor inserted into 5 meters of Mars bottom surface.

SIX will be used to monitor soil vibrations. Given the Mars earthquakes or meteorites that hit the surface, The study will reveal exactly what these seismic waves produce.. The HP3 penetrates 15 times more than other shovels or previous drillings. The amount of heat escaping from the intestines of the red planet. RISE will use the earth's radios and provide information about the core of the planet to assess the vibration of the rotation axis of Mars.
