How is NASA astronomers shake the seismometer in March – 2013/11/28


NASA is backward landing On Mars Mars Mars InSight. It has a cost of $ 993 million, capable of "hearing" the earthquake and is capable of exploring the functioning of another rocky planet.

This spacecraft is guided It started almost seven months ago and has already made 482 million kilometers. A part of its mission is to inform the current planet about the effort of sending human explorers to the NASA in 2030.

Mars InSight will be landing as of 2012, when the NASA wisdom manages to surface and planet Earth, now frozen and dried, to analyze the signs of life.

To do this, it is necessary to survive in a difficult atmosphere of the red planet, traveling at a speed of 19,800 kilometers, which only reduces the speed at 8 km.

Entry, descent and landing stages will begin on Monday at 4 in the afternoon (Argentina time). Half jokingly, NASA refers to this phrase "Six and a half minutes of terrorism".

Mars missed out on 43 missions, reaching 18 of the planet. That's a success rate of around 40%. All missions came from the United States. "It's a very difficult time for Mars to be very difficult," said Thomas Zurbuch, associate administrator of NASA's Science Missions Directorate.

"It's exciting that we are building the greatest success of the best landing ever landed on this planet, that is, the NASA team with its contractors and their collaborators."

InSight is called "Inner exploration", which will conduct seismic research, geodesy and heat transport.

With full fuel charge, InSight weighs more than 360 kg, similar to the Harley Davidson motorcycle. Its main instrument is the earthquake detection seismometer The French Space Agency (CNES) did.

"This is the only NASA mission created around a foreign tool," said Jean-Yves Le Gall, CNES President, AFP. That's why he added, "It's a key role in the United States, France," and improves understanding of Mars.

Sensors of the six sensors in the skin are very sensitive, which should be the slightest shaking of Marsen, such as Phobos on the face of the moon, meteoric impacts and perhaps volcanic activity.

Seismology has taught a lot about humans about 4.5 million years ago, but much of the Earth's evidence was lost with crustal recycling, due to tectonic plaques. This process is not in Martian.

In addition, a spacecraft can carry a "self-cap" probe that is 3 to 5 meters deep, measuring the temperature at underground and measuring the temperature and the amount of heat it escapes from the outside.

InSight landing will cushion with parpaid. The heat shield will help to slow down the ship and protect the friction of accessing the atmosphere of Mars.

The landing area is called Plane Elysium Planitia, NASA has designated "The largest parking lot in Mars".

NASA will know for a minute whether the landing was successful, but it would have to wait more than five hours to confirm the expansion of the equipment. That would be on Monday at 5pm (Argentina time).
