After covering about 300 million kilometers, the Insight NASA mission will reach the surface & # 39; Mars today and will install sismometru and thermal sensor to jiddeċifra the "internal fund" so-called "red plan".
This stationary module, which left at 5 & # 39; May by Base & # 39; Air & # 39; Vandenberg in California, will use a mechanical excavator to facilitate up to about 5 meters (16 feet) deep and measuring its internal temperature, plus & # 39; sismografu with any internal movement.
"It is the first mission that will study the deep interior & # 39; Mars", said the Spaniard Fernando Abilleira, deputy director of design and navigation of & # 39; Insight and part of the multidisciplinary and international team forming mission.
"By studying the propagation of the waves below the surface & # 39; Mars, through its seismometers, we will have more information on the evolution" in the last 3 billion years.
Abilleira, with 17 years & # 39; service in NASA space projects, is part of engineers and scientists from a day & # 39; Monday will study at the Laboratory & # 39; the Jet Propulsion & # 39; this agency (NASA JPL) in & # 39; Paltadena (California) near the planet, such as "pulsed," her temperature.
He added that through Spanish & # 39; 'tracking & # 39; precision "will comply" by reflections "during the two years & # 39;" primary experiments "the mission will entail.
To spread awareness about the formation of & # 39; Mars and other planets rock of the Solar System, such as the World, will be used to experiment Seismic for Internal Structure (SEIS), sismom manufactured by the National Center for Aerospace studies & # 39; France (CNES) and will discover "any movement on the surface of & # 39; Mars", said Abilleira.
The vibrations will be recorded by SIX may be caused by impact & # 39; meteorite or a small earthquake, although the seismic activity of the "red planet" is less than that of the World. "Through & # 39; of the wave motion study they spread under the surface & # 39; Mars, we can better understand the composition, the nucleus structure, the mantle and the crust of planet ", he added.
other tools
The other tool to acquire prominence is the probe of Physical Properties and (HP3) Heat Flux, built by the German Aerospace Center (DLR), which will be implanted in the Martian soil in & # 39; about 5 meters deep.
"This device has thermal sensors to collect information about the thermal activity of the red" planet, said Abilleira, stressing that Spain contributed to this environmental station mission (REMS) equipped with & # 39; meteorological sensors Martian environment.
This specialist in the trajectory of the spacecraft and paved the way of the robot "Curiosity", which reached the planet red f & # 39; August 2012, states that "landing on Mars is very complicated".
"All of atmospheric entry velocity is & # 39; about 20,000 kilometers per hour and at & # 39; less than 7 minutes we reduce that speed to 5 kilometers per hour", said Abilleira, graduate & # 39 ; Saint Louis University in Missouri.
After a journey of & # 39; more than 6 months, the mission will share insight on the fifth & # 39; evening & # 39; Monday, the Uruguay time, the Martian atmosphere and will come on the surface. Field robotic going to land scientific instruments will be installed on the Martian soil.
The Insight mission is expected to provide clues about how the Solar System originated 4,600 million years ago.
