Anxiety in the Insight as NASA Mars space trap approaching Red Planet



This composite photo created from over 100 images of & # 39; Mars taken by Viking orbiters in the 70s into the family of our solar system, Mars is Earth servants, the following approaches to the Humans who captivated the door for millennia. The attraction sure to grow on Monday with the arrival of & # 39; NASA Lander named Insight. Picture: NASA via & # 39; AP

Tampa – Seven & # 39; & # 39 years; work and journey & # 39; & # 39 nearly seven; months would be limited by nearly seven & # 39; & # 39 minutes; terrorism as NASA has gone beyond the last hour for landing & # 39; high of nuclear drama & # 39; Mars Insight to 993 million on Monday.

The purpose of & # 39; Mars is listening Insight & # 39; the quakes and tremors as a way to unlock the mystery of & # 39; inside of the Red Planet, as formed billions & # 39; years ago and, b & # 39; extension and other planets were formed rocky like Earth.

The unmanned spacecraft is the first NASA to try and close contact with the planet Earth since the Curiosity Rover 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.

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.

"I never consider a wife for granted. Mars is difficult", said Thomas Zurbuchen, associate administrator of NASA for the management of the science mission, on Sunday.

The entry phase, descent and landing nail beginning at 11: 47 am (time & # 39; 1940 GMT / 2140 SA) Laboratory of & # 39; the Jet Propulsion & # 39; & # 39 NASA in; Panadena, California, where the next control mission to Mars Insight.

orchestrated sequence carefully – already programmed prior 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 at 12,300 miles (19,800km) per hour, the heat protecting spacecraft discover the friction tbaffija as comes in & # 39; atmosphere & # 39; Mars .

The heat shield turns to a temperature of & # 39; 2,700 Fahrenheit (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 device combines running, further reducing space & # 39; 800-pound (365 kg) for speed & # 39; only about 5 mph 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 added that he "did not sleep that great", although he said he can & # 39; is because of his young men, to two years and four & # 39; years.

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

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

The National Center & # 39; Etudes Spatiales of & # 39; France (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 to the project were the Center for Space Research of the Academy of Sciences and Polish Astronika, with the Swiss Institute of Technology, and the Imperial College of Britain in London and the University & # 39; Oxford.

Together, these instruments will study geological processes, said Bruce Banerdt, the principal investigator of & # 39; Insight into the Jet Propulsion Laboratory of.

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.

NASA made one final correction of the course on & # 39; Sunday.

With the rest of all pre-programmed sequence of landing, all out of NASA scientists can do is cross their fingers and hope for the best.
