The probe will monitor the seismic activity of the red planet. The resulting data should help us understand how Mars and other Earth-like planets formed billions of years ago.
InSight was released almost seven months ago. Since 2012, when Marshal "Curiosity" floated on Mars, it was NASA's first attempt to hit the probe on a nearby planet.
More than half of the 43 global attempts to send Mars to Marshals, satellites and probes failed.
NASA is the only space agency to succeed. It invests in these missions for the first flight of people planned for Mars in the 1940s.
"We never evaluate (the success of) Mars as it is understood, Mars has problems," said scientist Thomas Zurbuchen of NASA on Sunday.

"Horror Moments"
The entry of the probe into the atmosphere and the landing phase will begin at 11 o'clock. 47 min (21 h 47 min Lithuanian time). The mission is managed by the NASA Reaction Research Laboratory (JPL) in Pasadena, California.
A well-programmed and programmed phase by the probe has been dubbed "six horror moments and a half".
The probe clings to the atmosphere of Mars faster than the ball, 19.8 ths. km per hour speed and will suffer a lot of friction. Heat protecting the outer layer of it, the layer weighs up to about 1.5 miles. Degrees Celsius, and the radio connection may be interrupted for a short time.
When the protective layer is released, three landing legs and a parachute unfold.
"There will be a bit of a free fall, and that's an absolutely scary idea for me," said Thomas Hoffman, InSight project manager.
But then, the probe motors will come on, which will further slow down the 365 kg weighing probe, and that planet's surface will reach about 8 kilometers per hour. speed.
From Earth, nothing can be controlled and no intervention will be possible if someone does not turn in that direction, the emotions, according to T. Hoffman, are controversial.
"At the same time, I am completely calm and excited," he said. "We did everything … but you never know what will happen."
T. Hoffman, a two-year-old and four-year-old, said that "sleeping was not very good," but added that it might be due to her sucking.
But when at 22 hours 1 min At the time of Lithuania, first signal showing that the probe had landed successfully, T.Hoffman promises to "give all his will for four years in itself".
Interior 3D map of Mars
Th.Zurbuchen described "InSight" as exceptional because it is equipped with instruments provided by several European space agencies.
The French National Center for Space Studies (CNES) has developed the SEIS instrument (Seismic Instrument for Internal Structure), which will record the earthquake.
DLR's German Aerospace Research Center provided a "deer" that could reach a depth of 5 m – deeper than any previous instrument – and measure heat flow.
The Spanish astrobiology center has produced sensors for the probe.
The Space Research Center of the Polish Academy of Sciences and the Polish Astronica Society, the Swiss Technical Institute, the British Imperial College and the University of Oxford have also contributed significantly to the project.
All of these instruments will study geological processes, says InSight principal investigator, Bruce Banerdt, working for NASA JPL.
By recording the vibrations in Marseille – earthquakes, meteorite shock waves or even volcanic activities – scientists can learn more about the planet and its formation.
The goal is to create an internal 3D map for Mars "to understand the inside of Mars," Banerdath told reporters.
Knowledge about Mars formation could provide more insight into the processes in which the Earth formed.
