Live as Our Space Planet Spacecraft, News and Top Stories in the United States



PASADENA (California) • In our Nuclear Power Plant, applauds like the Dutch powerless landing gear, called InSight, touched on Mars, covering almost seven years of travel from design to launch to landing.

The dramatic arrival of $ 993 million (just $ 1.4 billion) of a spacecraft – designed to listen to earthquakes and shocks as a way of discovering the inner mysteries of the Red Planet, how it formed billions of years and, as it is expanded, how other rocky planets Earth began forming – marked the eighth successful landing on Mars in our history.

"Touchdown has been confirmed," said the mission control officer at the Department of Aeronautics and Space, because it was disturbed by anxiety and excitement through space, and dozens of scientists jumped from their seats to hug.

"He was intense and you felt emotions," said administrator Jim Bridenstein in an interview with NASA's television.

Mr. Bridenstein also said that President Donald Trump and Vice President Mike Pence watched on television and called for congratulations to the US space agency.

"In the end, the day comes when people put us on Mars," Bridenstein said, adding that the goal was to do it by the mid-1930s.

The vehicle seemed to be in good shape, according to the first communications received from the surface of Mars.

  • MARS 3 (1971)

    Through the Soviet Union Mars 3 is the first spacecraft on Mars – December 2, 1971. Shortly after landing, it fails.

    VIKING 1 (1976)

    NASA Viking 1 is the first American spacecraft to successfully descend to Mars – on July 20, 1976. The Viking 2 passenger arrives to Mars on September 3, 1976.

    MARS GLOBAL SURVEYOR (1997)

    NASA Mars Global Surveyor agreed on September 11, 1997.

    MARS PATHFINDER (1997)

    Our Mars Pathfinder landed on July 4, 1997. His mission includes the first successful rover on Mars, called Sojourner.

    DUH I PRILIKA (2004)

    NASA Mars rover, the nickname "Spirit", arrived on January 3, 2004, three weeks before it was close, Opportunity, located on the other side of the planet.

    PHOENIX (2008)

    Phoenix Mars Lander is on May 25, 2008. Part of NASA's Scout program for smaller and lower costs, is designed to study water in the arctic arsenic arena and look for a living area.

    CURIOSITY (2012)

But, as expected, the dust that started during the landing darkened the first image of InSight that came back, which was strongly flashy.

The French Center National d 'Etudes Spatiales (CNES) has created an instrument Seismic Experiment for the internal structure, a key element for the sensitization of the earthquake.

The chief explorer of the French seismometer, Professor Philippe Lognonne, said he was "very comfortable and very happy" in the outcome.

"I just got confirmation that there is no stone in front of diggers," he said.

In the final key phase, NASA said InSight signaled to Earth that its solar panels – dual solar arrays of 2.2m width – opened and collected sunlight on the surface of Mars.

"The InSight team can make it a bit easier … now that we know that the solar spacecraft spacecraft is deployed and stuffing batteries," said Tom Hoffman, project manager at InSight.

The spacecraft is our first one that touched the neighboring planet of Earth since the rover Curiosity arrived in 2012.

More than half of the 43 attempts to reach Mars with rovers, orbits and probes of space agencies around the world have collapsed.

Nasa was invested in these robotic missions as a way to prepare for the first human explorers in the Marsa of the 2030s.

"We never take Mars for granted, Mars is difficult," said Dr Sutherland on Sunday. Thomas Zurbuchen, assistant administrator of NASA for the mission of science.

The launch, landing and landing phase began at 3.47 on Tuesday in Singapore at NASA's Jet Propulsion Laboratory in Pasadena, California, at the Mars InSight mission control mission home.

A carefully orchestrated series – fully pre-programmed on a ship's aircraft – developed over the next few minutes, coined "six and a half minutes of terror".

Accelerating faster than the bullet at 19,800kmh, the heat-shielded lander encountered burning friction as it entered the Mars atmosphere.

The heat shield descended to a temperature of about 1500 degrees C before it was discarded, three deployed landings, and the parachute came out, easing InSight to the surface of Mars.

InSight contains key tools contributed by several European space agencies.

In addition to the French CNES, the German aerospace center also provided self-centered tubers that can bury 5m on the surface – far from any instrument earlier – in order to measure the heat flow.

The Spanish Centro de Astrobiologia has made wind sensors, and three InSight's seismic instruments have been designed and built in Britain.

Another significant contribution comes from the Research Center of the Polish Polish Academy of Sciences and Astronomy and the Swiss Institute of Technology.

The goal is to map the interior of Mars into three dimensions, "so that we understand the interior of Mars as well as that we understand the outer appearance of Mars," said Dr. Bruce Banerdt, Chief InSight Researcher at the Jet Propulsion Laboratory.
