Mars's InSight Meter approaches Marsi at 19,800 miles per hour and will land on Monday with a view to launching its mission: listening to earthquakes and exploring the internal activity of the bedrock.
The ship must cope with the difficult result of the red planet's atmosphere and speed up its speed to only 8 kilometers per hour.
An unmanned spacecraft of $ 993 million was launched nearly seven months ago (May 5) at the Vandenberg Air Base in California and traveled around 482 million kilometers. Some of his duties are to inform the efforts of sending scouts on the red planet that Nasa hopes to receive in 2030.
Mars landing is the first since 2012, when a curiosity researcher
NASA landed on the surface and analyzed pebbles signs of life that could live next to the Earth, now frozen and dry.
The departure, landing and landing stages begin Monday at 19:47 GMT (2:47 pm, Colombia time). Half jokingly, Natassa they are referring to the stage of the "six and a half minutes of terror".
Its central tool is the Earthquake Measurement Measure developed by the French Space Agency (CNES).
Six earthquake sensors are so sensitive that they should reveal even the slightest tremor of Mars, such as the poor pulling of the Phobos moon, the effects of meteor and possibly volcanic activity.
"It's the first task that explores the deep inside of Mars," says Fernando Abilleira, deputy director of Inverness's planning and navigation. "By exploring the spread of waves under the surface of Mars, through its seismometer, we have more information on how the planet has developed over the last 3,000 million years" he added.
Seismology has taught mankind much of the Earth's formation, about 4.5 billion years ago, but much ground-based evidence has been lost through recycling driven by disk technology. This process does not exist on Mars.
Another important tool is the physical properties and thermal flow (HP3) built by the German Aerospace Center (DLR), which is implanted in Mars soil about 5 meters deep to provide the first accurate measurement temperatures inside and inside the heat from the inside.
The InSight drop is pressed with a parachute. Its thermal plate helps to slow down the platform and protect it from the friction of the red planet's atmosphere.
The landing site is the flat area of Elysium Planitia, which NASA has called "Mars's largest parking lot."
NASA knows in a matter of minutes whether the invoice is successful or not, but it will have to wait more than five hours to ensure that the devices are installed.
Of the 43 missions launched by Mars, only 18 have reached the red planet, the success rate is about 40 percent and all come from the United States. "Getting to Mars is very difficult," said Thomas Zurbuchen, Deputy Chief of NASA's Scientific Affairs Department.
"The exciting part is building the best of success that has ever landed on this planet, NASA's team with its contractors and their partners," he added.
Other probe details
The InSight name comes from "internal search using seismic studies, geodesy and heat transport". The spacecraft stops about one meter from the surface, and when it drives from solar panels, it reaches nearly 6 meters. The full fuel weighs more than 360 kg, almost the same as the Harley Davidson motorcycle.
