NASA, Mars countdown for landing on a seismometer

NASA in countdown for Landing on Mars on Monday probe Inside Mars, from 993 million dollarsand first He can listen to earthquakes and examine the inner workings of another rocky planet..

The unmanned spacecraft was launched about seven months ago and has traveled 482 million kilometers.

Part of the mission One day to report efforts to send human observers to the red planetNASA has something to get in the 2030s.

The landing of the Mars InSight probe is the first since the explorer's 2012 wonder NASA surfaced and analyzed the rocks for life signs that were now frozen and dry, inhabited by the planet on earth.

InSight must overcome difficult entry into the atmosphere of the red planetit is at a speed of 19,800 kilometers per hour and is rapidly dropping its speed at only 8 kilometers per hour.

The entry, landing and landing stage will start on Monday at 16:47 (GMT). Tomorrow's a joke on NASA "Six and a half minutes of terror."

Only 18 of the 43 missions launched on Mars have reached the red planet, a success rate of 40%.and they all came from the United States.

Olan It's very, very difficult to go to Mars, Thomas said Thomas Zurbuchen, NASA's Director of Scientific Affairs.

”The exciting part is that we are building on this planet, the success of the NASA team's best team of contractors and their collaborators.“

FRENCH SISMOMETER

The InSight name is derived. "Inland exploration using seismic investigations, geodesy and heat convection".

The spacecraft stops at a height of about one meter and extends to almost 6 meters when the solar panels are installed.

With full fuel, Inight weighs more than 360 kgalmost the same as a Harley Davidson motorcycle.

The central instrument is a Earthquake detection seismometer by French Space Agency (CNES).

"This is the only NASA task designed around a foreign-made instrument," CNES president Jean-Yves Le Gall told AFP.

Therefore, geliştirmek the United States, a basic task for France ”and added to improve Mars' understanding.

The six seismic sensors on the ship are too sensitive to detect the smallest vibrations in MarsThe weakness of the Phobos bear, the effects of meteors, and possibly the evidence of volcanic activity.

Seismology taught a lot about mankind's formation of the Earth about 4.5 billion years ago, but most of the evidence based on Earth was lost by the recycling of the shell guided by plate tectonics. This process is not available in Mars.

The ship also has a self-drilling probe that can dig up to a depth of 3 to 5 meters.To provide the first accurate measurement of underground temperatures in Mars and the amount of heat escaping from inside.

InSight landing will be buffered by a parachute. The heat shield will protect the ship from slowing down and friction of entering the Mars atmosphere.

Landing area is a flat area called Elysium PlanitiaNASA said it was "the biggest parking spot on Mars."

NASA will know in a few minutes whether the landing has been successful, but will have to wait more than five hours to verify the deployment of the equipment.
