The probe will follow the seismic activity of the Red Planet. The data obtained should help us to find out how Mars – and in addition other earthy planets – were formed billions of years ago.
InSight was released almost seven months ago. Since 2012, when the marshal floated "Curiosity" to Mars, it is NASA's first attempt to hit the probe on a neighboring planet.
More than half of the 43 global attempts to send Mars to Marshals, satellites and probes were unsuccessful.
NASA is the only space agency that is successful. She is investing in these missions in preparation for the first flight of people planned for Mars in the 1940s.
"We never evaluate (successfully) Mars as it is understood, Mars has problems," said NASA scientist Thomas Zurbuchen on Sunday.
"Horror moments"
The entrance of the probe into the atmosphere and the landing phase starts at 11 o'clock. 47 minutes (21 hours 47 minutes Lithuanian time). The mission is managed by the NASA Reaction Research Laboratory (JPL) in Pasadena, California.
A well timed and probe-programmed phase was called "six and a half horror moments".
The probe will stick more quickly to the Mars atmosphere than the bullet, 19.8 pcs. km per hour speed, and will suffer a lot of friction. From the heat that protects the outer layer, the layer pounds to about 1.5 thousand. Celsius degrees, and the radio link can be interrupted for a short time.
When the protective layer is released, three landing legs and a parachute will unfold.
"There will be a bit of a free fall, and it's an absolutely frightening idea for me," said InSight project manager Thomas Hoffman.
But then the probe motors will go on, which will slow down the 365 kg probe, and this surface of the planet will reach about 8 kilometers per hour. speed.
Nothing can be controlled of the earth, and it will not be possible to intervene in any way, if someone does not turn in that direction, then emotions, according to Hoffmann, are contradictory.
"At the same time I am completely calm and very excited," he said. "We have done everything … but you never know what will happen."
T. Hoffman, a child of two and four years old, said that he "does not sleep well", but added that this could be due to his fallen offshoots.
But when at 10 pm 1 minute T. Hoffman promises "to show his full will in himself in the first year in Lithuania" to show that the probe has landed successfully.
Mars inner 3D map
Th. The Zurbuchen probe is called InSight unique because it is equipped with instruments from various European space organizations.
The French Center National d 'Etudes Spatiales (CNES) has developed the Seismic Instrument for Internal Structure (SEIS) instrument, which will register the earthquake.
The German aerospace research center of the DLR created a "deer" that could reach a depth of 5 m – deeper than any other previous instrument – and measure the heat flow.
The Spanish Astrobiology Center produced sensors for the probe.
The Space Research Center of the Polish Academy of Sciences and the Polish company Astronica, the Swiss Technical Institute, the British Imperial College and the University of Oxford also contributed significantly to the project.
All these instruments will study geological processes, says InSight & # 39; s lead researcher, Bruce Banerdt, working at NASA JPL.
By recording vibrations in Marseille – earthquakes, meteorite shock waves or even volcanic activities – scientists can learn more about the interior and the formation of the planet.
The goal is to create an internal Mars 3D map "to understand the interior of Mars," said B. Banerdath to reporters.
Knowledge about Mars formation can provide more knowledge about the processes in which the earth has been formed.
