NASA's InSight to land on Mars after a six-month trip

A six-month journey of NASA's spacecraft on Mars is approaching its dramatic final.

The InSight Terminal is meant to be touched within hours because anxiety develops among those involved in the $ 1 billion international effort.

Dangerous descent of InSight through the Martian atmosphere has stomachs and nerves stretch to the maximum. Although an old pro, NASA has not attempted a landing on Mars for six years.

InSight is scheduled for landing on Tuesday (May 7th) (AEDT).

The robotic geologist – designed to explore Mars' mysterious interiors – has to go from 19,800 km / h to zero in six minutes while perforating the Martian atmosphere, throwing a parachute, burning the driving forces and creating three legs.

It targets the flat red fields, we hope they are low on the stones.

The global success rate of the Earth at Mars is 40%.

"Mars landing is one of the most challenging unique jobs people have to do in planetary exploration," said Bruce Banerdt, principal investigator at InSight. "It's such a difficult thing, it's such a dangerous thing that there's always a pretty uncomfortable chance that something could go wrong."

This is not a rock collecting expedition. Instead, the 360-kilometer station will use its 1.8-meter robotic arm to place a mechanical harrow and a mechanical seismometer on the ground.

The hammer hammer will drop 5 meters down to measure the warmth of the planet, while the ultra-high-tech seismometer listens for possible marsquakes. Nothing like this has been tried before on Mars. No experiment has ever been robotic from the spacecraft to the Martian surface. No lander dug more than a few centimeters, and no seismometer ever worked on Mars.

Examining the deepest and darkest interior of the planet Mars – still preserved from its early days – scientists hope to create 3D images that could show how the rocky planets of our solar system have now formed 4.5 billion years and which proved to be so different. One of the great questions is what made Earth so hospitable to life.

Mars once have rivers and lakes; deltas and lakes are now dry, and the planet is cold. Venus is an oven due to the thick atmosphere, captured by the heat. Mercury, closest to the sun, has a surface that is well burned. Planetary know-how gained from InSight's two-year exploitation may even turn into rocky world beyond our solar system, according to Banerdt. The findings on Mars could help explain the type of conditions to the so-called "exoplanet" and how they fit into the story we are trying to figure out about how the planets are formed, "he said.

Focusing on planetary building blocks, InSight has no life-saving capabilities. This will be left for the future rovers. NASA's Mars 2020 mission, for example, will collect rocks for a possible return that could support evidence of ancient life.
