Anxiety at NASA as Mars spacecraft touches Insight at Red Planet

The purpose of & # 39; Mars is to listen Insight & # 39; the quakes and tremors as a means to reveal the mysteries of & # 39; inside of the Red Planet, as formed billions & # 39; years ago, and b & # 39; extension, designed as a form of & # 39; rocky planets like Earth.

LOS ANGELES – The superior of Nasa scientists admitted to sleepless nights, sweaty palms, stomach pain and moments & # 39; pure terror as their space & # 39; 993 million Mars Insight approved high drama finale Monday: landing on Mars.

The purpose of & # 39; Mars is to listen Insight & # 39; the quakes and tremors as a means to reveal the mysteries of & # 39; inside of the Red Planet, as formed billions & # 39; years ago, and b & # 39; extension, designed as a form of & # 39; rocky planets like Earth.

The unmanned spacecraft launched nearly seven & # 39; months ago, and is the first Nasa to try adjoins the neighboring planet Earth since the Rover Curiosity arrived in 2012.

More than half of & # 39; 43 attempts to reach Mars with & # 39; rovers, orbitaturi and probes by space agencies from around the world have failed.

WATCH: How will Nasa & # 39; s Insight Space Land Land on Mars?

Nasa is the only space agency għamletha, and is invested in & # 39; these robotic missions as a way to prepare for the first human explorers linked & # 39; Mars in 2030.

"Never going to Mars. Wife is difficult," said Thomas Zurbuchen, associate administrator of Nasa for scientific mission directorate, on Sunday.

"PENSION B & # 39; robust terrifying"

The high drama of the entry phase, descent and landing begins at 11: 47 am at the Laboratory & # 39; Propulsion of the NASA Jet f & # 39; Panadena, California, where next control mission to Mars Insight.

orchestrated sequence carefully – already programmed completely on board the spacecraft – occur during the next few minutes, created "six and a half minutes of & # 39; terror."

Lightening b & # 39; move faster than a bullet in & # 39; 12,300 mph, the heat protecting spacecraft encounter & # 39; to & # 39; Friction due to enter into & # 39; atmosphere & # 39; Mars.

The heat shield turns to a temperature of & # 39; about 1,500 Celsius. Radio signals can be lost briefly.

The heat shield disposed, three riding & # 39; deploy the landing, and the parachute off.

"We release for a little while, that he thought absolutely terrible for me," said Tom Hoffman, the project manager & # 39; Insight.

But then, the thrusters of the Space begin to extinguish, and further reduce the area & # 39; 800 pounds (365 kilograms) to speed & # 39; about 8 km per hour when it reaches the surface.

Since m & # 39; there is no joystick back on Earth for this spacecraft, and no way to intervene if something goes wrong, Hoffman described his emotions as a composite.

"I am completely comfortable and completely nervous at the same time," he said.

"We did everything we could think to make sure that we will be & # 39; successful, but you'll never get & # 39; it will happen."

Hoffman, who is a father & # 39; & # 39 two and four; year, added that "did not sleep that great", although he said they can & # 39; due to the many young kids.

But when the first signal arrives at 2001 GMT, hopefully showing that the operator has established itself, intact and upright, "I'm going to stay in dissolved four indoor & # 39; years ago in & # 39; that point" , said.

Zurbuchen Insight described as "unique" because of the high waist artery has instruments that were contributed by various European space agencies.

The Center of & # 39; France & # 39; National d & # 39; Etudes Spatiales (CNES) made Instrument & # 39; Seismic Experiment for Internal Structure (SEIS), the key element for sensing quakes.

The German Aerospace Center (DLR) has provided self-blocking mole can & # 39; vacate 16 feet (five meters) to the surface – more than any previous instruments – to measure the heat flow.

The Centro de Astrobiologia of & # 39; Spain has the wind sensor space.

Other significant contributions for the project came from Space Research Center of the Polish Academy of Sciences and Astronika in Poland, the Swiss Institute of Technology in Switzerland and Imperial College and the University & # 39; Oxford in Britain.

Together, these instruments will use physics to study geological processes, said Bruce Banerdt, the principal investigator of & # 39; Insight Laboratory of & # 39; Jet propulsion & # 39; Nasa.

By listening & # 39; tremor on Mars, whether from impacts & # 39; storms or weather or even volcanic activity, scientists can learn more about the interior and reveal how the planet was formed.

The aim is to enter the party & # 39; inside & # 39; Mars in three dimensions, "so we understand inside & # 39; Mars and we understand each out & # 39; Mars", said Banerdt.

Understanding how Mars formed can & # 39; reveal more about the processes that formed the Earth also.
