The landing of the InSight probe on Mars is still here



The landing of the InSight probe on Mars is still here

In a complex mission, this spacecraft will be the first to explore the deep interior of the red planet where it will install a seismometer and a thermal sensor.

LOS ANGELES.

after lid for 300 million kilometers, The mission of InSight from NASA will reach today the surface of Mars and will install a seismometer and a thermal sensor to decipher "deep interior" the call red planet,

It is stationary modulewho flew before 5 May from Military Base Vandenberg, in California, will use a mechanical excavator to break through to about Depth 5 meters and measures its internal temperature, In addition to any internal movement with the help of seismograph,

This is the first mission to study the deep interior of Mars, "said Fernando Abileira, deputy director of design and navigation at InSight, and part of the multidisciplinary and international team that is the mission.

Examining the wave propagation under the surface of Mars, through its seismometer we will have more information on how the planet has evolved "over the last 3 billion years," he added.

Abileyra, who has 17 years of NASA space projects, is part of the engineers and scientists who will study the "vital signs" of the neighboring planet on Wednesday at the JPL-NASA Laboratory of Pasadena, Calif. , such as its "ripple, temperature".

He added that through "accurate tracking," they would observe the "reflections" in the two years of "primary experiments" that the mission would mean.

To expand the knowledge about the formation of Mars and other rocky planets like Earth, the Earthquake Seismic Experiment (SEIS) will use a seismometer produced by the National Center for Aerospace Research in France (CNES). "Any movement on the surface of Mars," Abileira explained.

The vibrations that will be recorded by SEST may be caused by the impact of a meteorite or a small earthquake, although the seismic activity of the "red planet" is less than that of Earth.

By studying the movement of the waves that spread under the surface of Mars, we can have a better understanding of the composition, structure of the core, the mantle, and the crust of the planet, "he added.

The other instrument that gains prominence is the Probe for Physical Properties and Heat Flow (HP3), built by the German Aerospace Center (DLR), which will be implanted in Martian soil at a depth of about 5 meters.

This instrument has thermal sensors that will gather information about the thermal activity of the red planet, "said Abileira, who stressed that Spain has contributed to this REMS mission equipped with meteorological sensors for the Martian environment.

This spacecraft trajectory specialist, who follows the Curiosity robot's path that reached the red planet in August 2012, points out that "landing on Mars is very complicated."

The speed of entry into the atmosphere is about 20,000 kilometers per hour, and in less than 7 minutes we have to reduce that speed to 5 kilometers per hour, "says Abileira, who graduated from St. Louis University in Missouri.

After a journey of more than 6 months, the InSight mission will pass through three afternoons on Monday, the Eastern Time in the United States (around 14:00 am Mexican time), the atmosphere of Mars and the surface will be established.

The robot arm will descend from the scientific instruments that will be installed on the Martian soil.

Part of the mission is two Mars Cube One vehicles (Marco Cube One), which will be first tested in the "deep space," as Abileyra said, and using tiny components will test a new method of transmitting information to Earth,

The Insight mission will focus on an unpublished study that is expected to provide clues about how the solar system originated about 4600 million years ago, and how life is spread.
