NASA has resumed. For six years we have landed the cursor vehicle, An object returned to the red planet. This week, after seven years of research and development, InSight has seven months of mobile space and "seven-minute fear" to spread its equipment and send its first message. Three tide legs, 55 million kilometers of Earth. And despite being easy for today's technology, They have successfully achieved 40% of all the missed missions.
The most complex complexity of heavy earth testing in Martian sand is a fixed atmosphere: superficial pressure does not exceed 1% of the earth and the resistance of the boat shows its resistance. To do it before crashing, engineers need to get off Synchronize thermal blocks, parachutes and rocketsin less than seven minutes.
This Monday, 17 minutes before (Argentina's time), InSight Marsen entered the civil field at 12 degrees on the planet. If there were more, burn, less bounce, and eventually lost in space. The 20,000 km / h probe has been moved, three to four times faster than the rifle bullet. Thermal protection was heated to 1,500 ° C, the temperature of the Sun's surface.
It was the place to go down Plain Elysium: In addition to the soft and dusty extensions, it was named "the largest parking lot in Mars", with the idea of minimizing the risk of casualties due to a few geographical features. It was chosen at 22 options, 600 kilometers from the fall point. wisdom

The process was perfect: activating the parachute, spreading the legs Reduce speed by 19.800 km / h in seven minutes. "Horror" period, in which the whole mission is mistaken for a minor mistake.
"Here I Want!", The message was tweeted through the official Zonda account, to reveal the first image that was approaching the Martian surface.
"My first photo on #Mar. My lens cover has not been removed yet, but I have had to show a first look at my new home," said the space agency later, while the fiestas were under the control of the Propulsion Laboratory. NASA Jet in Pasadena, California.
"I'm sorry, Mars, and soon I know your heart, with this safe landing, I'm here. I'm home", He later published the InSight module, directly through his social network, his Earth journey.
Up to the last moment, technical adaptations were made. NASA "has made the last touches of the algorithm that drives the entrance, descent and landing gear (EDL) two hours before reaching the atmosphere".
As Earth and Mars were built similarly, NASA expects the mission to help them understand why they are so different. And while the evolution of our planet was hidden by millions of earthquakes and rocky rocks over the mantle, Mars had less than a geologically active asset for more than 4,500 million years ago.
The InSight module, priced before landing $ 993 million, includes data from the instrument: the seismometer SEIS, the RISE device (when determining the position of the probe during oscillation at the rotation axis); and the HP3 heat flow sensor, which is 5 meters below ground level in Martian.
The SIG will be used to control the soil vibrations. In addition to facing the surface of the earthquakes or meteorites in Martian, This study produces the seismic waves that produce it. HP3 introduces 15 times more ground than the previous shovel or previous drilling The amount of heat that escapes the red planet's nose. RISE will use earth radio stations to evaluate the wobble of the Mars rotation axis, providing information about the planet's core.
