After half a year of Mars trip NASA probe is the famous "six and a half minutes of terror", which is used in a parachute and laskeutumisvoimia, in order to avoid falling over. If everything goes as planned, it slows down only 2.24 meters per second and returns padded feet to the red planet to explore its interior. The landing is scheduled this Monday.
Another possibility is not the head of the project, Tom Hoffman. "The team has been working for several years and is ready for this moment, and finally we can put all the preparation into action"he summarized.
The sensor door is a rectangle 10 x 24 km. The goal is that 479 million kilometers as the junction required, is for scientists, soccer metaphor, "How to make a goal of 130,000 km". During the first 25 seconds, InSight discards its heat shield and one minute before touching the Mars desert that uses it to detect the radar's speed and distance to the ground.
Despite optimism uncertainties exist and are justified: only 40% of missions dispatched by various space agencies to failed Mars have been successful. For this reason, it is important to supply precision but also aerodynamic factors such as vessel attraction and atmospheric variables such as wind speed and atmospheric density.
Even though InSight's features have a good deal on the American Space Agency, it can choose the friendly surface that they considered "Elysium Planitian" as the largest parking space for Mars. "Also a ship with a total weight of more than 360 pounds and costing about $ 1 billion prepared engineers for dust as needed. "When it arrives, the Earth team starts the process of choosing the best places to place scientific tools on the", an expert described.
The task is to explore the interior of the red planet for the first time with two main tools. Seismograph that monitors and analyzes soil oscillations caused by earthquakes and meteorites. And a thermal flow sensor that penetrates 15 times more ground than any other prior hardware, accurately determine the amount of heat it contains.
NASA needs to be accurate to measure "Vital Signs" (seismology) and its temperature (heat flow). "Engineers are going to decide on the next steps, and when the tools are in place, InSight will spend the next March (26 Earths) to follow these signs," Hoffman said.
In addition, the specialty cameras produce high-quality color images, and if that is not enough, two Mars Cube One devices have flown from InSight and are trying to send information and open a new way of communicating with the country.
Why explore Martian interior design? Decades ago and in several reports it was stated that it should be one of the scientific priorities, and although several tasks were proposed over the next few years, no one succeeded. That is why the international expectation this Monday: French and German space agencies, which provided the most important tools, also participated in the United Kingdom, Austria, Belgium, Canada, Italy, Spain, Switzerland and Poland.
By exploring Mars's deep interior, we can learn how other cliffs, such as the earth and the moon, formed. In short, it is a close relatives born from the same source, over 4500 million years ago.
What we learned from this cold, rocky desert country could illuminate our own existence. And above all, it is crucial to fill one of the great dreams of marching in the history of the Revolution: to send the human explorer to the surface of Mars for years to come.
