The United States space agency, NASA, on Monday (11/26) will make a new effort to land a robot vehicle on Mars on a flat land north of the planet's Equator called Ellis Planitia.
The car, the insight, carries a set of instruments – some of Europe – in an effort to formulate the inner structure of the rocky planet.
The signal of the vehicle that confirms the landing safely should be available on Monday around 19:53 GMT, (Tuesday, 2:53 PM).
As previous landing missions, Insight should be able to get away from 'seven minutes of terror' – The time that is necessary for vehicles to enter the thin atmosphere of Mars at HyperSonic speeds to slow down the speed of walking and then gently set up on Mars.
Many have tried; most fail. "As humans, as explorers – the chances are less than 50%," said Science Chief Nasa, Thomas Hebbutchen. "Going to Mars is really a very difficult thing."
What are the opportunities? InSight?
Insight uses a variety of things similar to previous NASA explorers, Phoenix.
Among others, a combination of heat shields, parachutes and retro-rockets, which proved to be successful in launching a Phoenix vehicle in 2007 at the North Pole's Mars.
Engineers in the Mission Control Room in the Jet Propulsion Laboratory in California are very aware of the statistics of the success of landing on Mars.
"We have made all the preparations that we can be able to think of to ensure that content (coming through the Martian atmosphere), decreases and landings (EDL) run as smoothly as we imagined," explains the project manager Tom Hoffman.
"But Mars as a planet is not always friendly, I think our team is ready, our spacecraft is ready." "We do not know if Mars is ready," he told BBC News.
How is the last situation?
The engineers who are closely connected to the weather are closely watching the weather on the red planet, looking at dust storms and signs of strong winds that can make the insight difficult to penetrate the atmosphere.
The track has changed slightly on Sunday, to make sure it is on a perfect track with the landing zone targeted at Elysium Planitia.
There is not much now that the NASA team can do the results. The whole process must take place automatically, because every command takes eight minutes to travel 146 million km between Mars and Earth. You can not use the audio player to control a vehicle that is so far away.
Insight will send a message when showing up to the surface of Mars. This message will be forwarded to two small satellites that will fly over it. Radio telescopes on Earth will also track what happens to the insight vehicle, but in case the main communication lines do not function.
Within the perfect landing, Insight is programmed to take pictures quickly from its closest environment that can reach the ground in the first 30 minutes range from the vehicle on the surface of Mars.
What's different about this mission?
This will be the first expedition that specializes in investing in the interior of the planet Mars.
Scientists want to know how the world is built – from the heart to the crust. Insight has three major experiments to achieve this goal.
The first is a French-English seismometer package that will be lifted to the surface to listen to Mars, Mars Seismicity & # 39 ;. The vibrations will reveal where the layers of stone are and what they are made.
"German mice" will grow up to 5 meters underground to record the planet's temperature, which will give an idea of how active the planet Mars is.
And the third experiment will use radio transmission to determine exactly how the planet moves on its axis.
One of the project scientists, Suzanne Smarkarar uses this analogy: "If raw eggs and half eggs are rotated, the movements of both will be different because of the distribution of the liquid inside. And now we really do not know whether the heart of Mars is fluid or tough, and as a great place. "Insight will give us this information."
What is the need?
Scientists understand their health, as the land interior is structured, and have a number of models that explain the beginning of the Earth's architecture at the birth of the solar system more than 4.5 billion years ago. But the earth is a data point and Mars will provide a different perspective on how rocky planets shape and evolve over time.
Insight major scientist Bruce Baumert said: "The little details about how planets evolve is what we think is the difference between a lot of land where you can make your skin darker, and a lot like Venus where you will burn in seconds. Site as Mars where you will
