Mission Insight to Mars: why is it so hard to go ashore on the red planet?

InSight will enter the Martian atmosphere at 19,800 kilometers per hour and must reduce its speed in at least seven minutes directly to 8km per hour for landing successfully.

This is the first spacecast that will be Mars heart survey. And it is expected that he will land on this red planet on Monday at 7:53 GMT.

The mission InSight There are instruments that allow you to surface a & # 39; planet to a depth that is ever reached and its output diffused; red planet.

InSight, the NASA project with the participation of European partners, will be The first aim is to put seismographs on Martian land.

  • "Mars was water and it was hot for a long time on Earth to live"

The probe left for Mars on May 5, and the Monday presence – if it happens according to its plan – amazing achievement.

Mars landing so badly about two-thirds of the attempts have failed.

Why is it so difficult to land on Mars?

The probe, which is six meters long and 700 kilos of weight, is recorded to go into a flat section called Elyseum Planitia, which NASA says as "the largest car park on Mars."

In order to come down in the right place, InSight must enter the Martian atmosphere within a window only from 24km to 10km.

A tough move needs to be accessed to the atmosphere and to the surface.

The probe will go into the distance Martian atmosphere Six times higher than a high speed shot and he needs to be greatly reduced, he explained Jonathan Amos, Science Writer in the BBC.

A recent European effort, in 2016, ended with an investigation that collapsed the surface.

InSight will enter the Martian atmosphere at 19,800 kilometers per hour and must reduce its speed just 8km per hour. That bad downturn should take place in a place just just under seven minutes.

One of the problems is that Mars's atmosphere is just 1% of Earth's Earth's atmosphere, so there is not much waste to reduce the speed of its boat.

NASA hopes to thrive by combining machines: salvage captain, parachute and retro-rocket to slow down the scrutiny.

The US space agency explained that the capsule would have to resist temperatures near 1,500 degrees Celsius when it enters the Martian atmosphere.

"We have done everything we can do successfully," he said. Julie Wertz Chen, one of the scientists about the purpose.

"But it's really real, it's very difficult to come ashore on another planet."

"We do not say we'll reach it easily, because you do not know what amazing things Mars will give you."

Martian earthquake

Item InSight is the first one Detailed x-disease of Mars inside and it will still be on the red planet 728 days, about Martian year or about two years Land.

The probe is seismographs that allow us to accept the Martian earthquake.

Seismometers try to capture a British, one British and one Martian earthquake made with tectonic movements or meteorite effects.

And by studying seismic beasts, it is possible to explore the inner stone rows of Mars, from the rubbish, the banner and the neck.

"Earthquake is almost as a real lamp", he explained the principal mission scientist, Bruce Banerdt.

"It illuminates within its planet with loose waves. the seismometer is like a camera that gathers these waves to make an image. Pixel accordingly, we will reconfigure 3D representation within the planet. "

The ship is the first seismographs on the Martian surface.

Another machine will enter Martian ground to a depth of five meters to measure the heat that is discharged inside a & # 39; planet.

And the probe machine has also been developed by Spanish scientists, Twins, which allow to measure the speed and wind temperatures, as well as a device to alter the distribution of a planet.

Mars and Earth

"Scientists know the structure of the Earth inside well and have modules for explaining the Solar Power Initiative for more than 4,500 million years ago," he explained. Jonathan Amos, a BBC scientist, who will accompany the & # 39; Excavating from the work-keeping center, the NASA Laboratory Jet Propulsion, JPL for its English language measurement, in California.

There are two smallest boats called Mars Cube One, or MarCO, have been traveling separately to Mars behind InSight and send them to Earth data about the invasion.

"But the ground is just a window in that history and Mars will allow us to gain a better understanding of how to create a rocky plant that has grown over thousands of years," said Amos.

InSight will help the scientists why the massive change of Mars and the Earth was so different and what elements were essential for living in our planet.

Two miniature spacecraft Convener together Mars Cube One, no MarCO, which is separated from InSight shortly after its launch, has been traveling to Mars as part of a separate NASA test.

MarCO is the first confidence in the deep place of CubeSats, a class of shipwreckers that go using small technology.

Marco successfully succeeds Mars to try to attract data from InSight as it enters the Martian attack and land, and the event can be survived through NASA Television.

If the exams work, it may be the start of a new data type to be & # 39; space mission communication on Earth, according to their spatial group.
