Mars landing platforms for NASA; anxiety, building a day out



CAPE CANAVERAL, Florida – Just one day, the NASAPS spacecraft has turned its attention to Mars, approaching like an arrow without going back.

The InSight time of six months and 300 million kilometers (482 million kilometers) came in an uncertain final final on Monday afternoon.

The robotic geologist, designed to study the interior of Mars, has to move from 1900 km / h to zero for six minutes when it penetrates the Mars atmosphere, launches a parachute, lights up its downhill engines and, hopefully, lands on three legs.

This is NASA's first attempt to land on Mars in six years, and all participants are understandably worried.

NASA's top NASA scientist Thomas Zurbuben confided on Sunday that his stomach is already shattering. The hardest thing to do is sit on his hands and do nothing, he said, except that he hoped and prayed everything perfect for InSight.

"Mars landing is one of the most difficult individual tasks people have to do in exploring the planet," said InSight leading scientist Bruce Banner. "It's such a difficult thing, it's so dangerous that there's always a very unpleasant chance that something will go wrong."

Mars's Earth's success rate is 40 per cent, counting every attempt to fly, orbital flight and landing from the US, Russia and other countries dating back to 1960.

But the US has taken seven successful landings on Mars in the past three decades. With just one failed touchdown, this is an enviable record. No other country has managed to set and manage a spacecraft on the dusty red surface.

InSight can give NASA eighth victory.

I'm shooting for Elisium Planice, a plain near the Martian equator, which the InSight team hopes to be flat as a parking lot in Kansas with a few, if any, rocks. This is not a rock gathering expedition. Instead, a 360-kilogram stationary airplane will use its 1.8-meter robotic arm to place the ground a mechanical mole and a seismometer on the ground.

The self-destructive mall will erupt 5 meters down to measure the warmth of the planet, and the ultra-high-tech seismometer listens for possible benefits. Nothing like that had ever been attempted before in our neighboring neighbor, nearly 160 million kilometers.

No experiments have been robotically moved from the spacecraft to the actual surface of Mars. None of the droughts have dug more than a few centimeters and no seismometer ever worked on Mars.

Examining the deepest and darkest interior of Mars, preserved from the earliest days, scientists hope to create 3D images that could reveal how the rocky planets of our solar system formed about 4.5 billion years ago, and why proved so different. One of the big questions is what made Earth so hospitable to life.

Mars had once run rivers and lakes; deltas and ice beds are dry and the planet is cold. Venus is a furnace due to its dense atmosphere. Mercury, closest to the sun, has a surface that is well baked.

The planetary know-how accumulated in the $ 1 billion two-year InSight operation may even turn into rocky world outside our solar system, according to Banerdt. The findings on Mars could explain the type of conditions in these so-called "exoplanets," and how they fit into the story we are trying to understand about how the planets are formed, "he said.

Focusing on planetary building blocks, InSight does not have the ability to discover life. This will be left for future ruvers. For example, the NASA Mars 2020 mission will collect rocks for eventual return, which may contain evidence of ancient life.

Since it's been so long since NASA's last Massive Ground Section – "Curiosity" in 2012 – Mars Mania conquers not only cosmic and scientific communities, but everyday people.

Scrutinizing countries are planned coast to coast in museums, planets and libraries, as well as in France, where the seismometer of InSight is designed and built. NASDAQ's giant NASDAQ screen in Times Square, New York, will begin broadcasting NASA television one hour before the InSight scheduling at 3am. EST touchdown; so will be the Udvar-Hazy National Air and Space Museum in Chantilly, Virginia and the Museum of Nature and Science in Denver. The InSight spacecraft was built near Denver by Lockheed Martin.

But real action, at least on Earth, will be developed at NASA's Jet Propulsion Engine in Pasadena, California, at the home of InSight's control team. NASA provides a special 360-degree online broadcast from the control center.

Confirmation of a touchdown may take minutes – or hours. At least there is eight minutes of communication between Mars and Earth.

A pair of briefcase-sized satellites ending InSight, as the hangover in May will try to transmit its radio signals to Earth with a potential nine-minute delay. These experimental CubeSats will pass directly behind the red planet without stopping. Signals can be moved directly from InSight to radio telescopes in West Virginia and Germany. It will take longer to hear NASA's orbits from Mars.

Project Leader Tom Hoffman said he was trying to keep himself calm until the hours were over. Once InSight radiates his home from the surface of Mars, he expects to behave very well with his three young grandchildren at Thanksgiving dinner, running like crazy and screaming.

"Just to warn someone sitting near me … I'm going to let go of my inner 4-year-old, so be careful," he said.
