InSight probe to examine interior of Mars planet for the first time


After a half-year journey to Mars, the NASA probe will have a famous "six-and-a-half-minute horror" that you must use a parachute and landing thrusters to avoid a collision. If everything goes according to plan, it will slow down to only 2.24 meters per second and will rest the pillow feet on the red planet to examine its interior. This is scheduled for Monday.

Another possibility is not to go to the project manager Tom Hoffman. "The team has been working for a few years and is ready for this moment. We can finally put all our preparation into action"Summarize.

The entrance door for the probe will be a rectangle of 10 x 24 km. A goal, according to the transition required 479 million kilometers, for soccer players, football metaphor, "How to make a destination from 130,000 km". During the first 25 seconds of the approach, InSight will use the heat shield and Mars one minute after touching the desert to detect the distance to the ground and the ground.

Despite optimism, uncertainties are present and well established: only 40 percent of the missions to the rebellious Mars have been successful by different space agencies. For this reason, aerodynamic factors such as the precision to be entered as well as the drift of the ship, and atmospheric variables such as wind speed and atmospheric density will also be important.

According to the features of InSight, the American space agency has a great spot in favor of it:; The largest park in Mars & may choose a friendly surface, which they call the plains of Elysium Planitia. In addition, the ship, which had a full load of more than 360 kilos and cost about $ 1 billion, was prepared by the engineers for a dust storm. "Once upon a time, the Earth team will launch the process to select the best places to place scientific tools"The expert has been described.

The mission will first attempt to examine the interior of the red planet with two main instruments. Seismograph to monitor and analyze soil vibrations triggered by earthquakes and meteor effects. And a thermal flow probe that will penetrate the ground 15 times more than any other previous equipment, to accurately determine the amount of heat entering from the inside.

For NASA you will have a control to measure it. "Life signs" From the pulse (seismology) and temperature of Mars (heat flow). . The engineers will take the time to decide the next steps, and once the tools have been fulfilled, InSight will spend the next March (26 months of the month) watching these signs.

In addition, special cameras will produce high-quality color images, and if not, two spacecraft named Mars Cube One will fly behind InSight and attempt to transmit data and open a new way of communication with the Earth.

Why are we investigating the interior of Mars? Several decades ago, and several reports found that it should be one of the scientific priorities, and although several missions were proposed in the following years, none of them successfully flew. For this reason, the international expectation for this Monday: French and German space agencies, which provide the main instruments, cooperated with the important participation of the United Kingdom, Austria, Belgium, Canada, Italy, Spain, Switzerland and Poland.

By studying the deep interior of Mars, we can learn how other rocky planets like Earth and moon are formed. In short, 4,500 million years ago is a close relative of the same primitive elements.

What we learned from the cold, rocky desert world could shed light on our own existence. And above all, the conquest of space will be determined to carry out one of the great dreams of the march in history: to send a human explorer to the surface of Mars in the coming years.
