WBecause there are no on board life detectors, its main objective is not to look for signs of life, past or present. But that does not mean that it will not be able to provide such clues.
"When InSight will break into the Martian soil, we will learn more about how Mars and Earth are formed. We will learn more about where we came from and why these two rocky worlds are so similar but so different "Bill Nye, said the director of the nonprofit planetary society. "We may find out more about what kind of planets can have life. InSight is more than a mission of Mars – it is a mission of the solar system."
Mars is much less geologically active than the Earth, so its interior is closer to being in the initial state – a tantalizing time capsule.
InSight comes to "revolutionize the way we think about the interior of the planet," said the head of the Nasa scientific mission, Thomas Zurbuchen.
Place of landing
InSight headed for a land called Elysium Planitia, an area that astronomers describe as "the largest parking lot on Mars."
A considerable equatorial field, Tom Hoffman, project manager of InSight, hopes to be "like a Walmart car park in Kansas."
Nasa was looking for a more flat area so the lander did not overturn and thus kill the mission so that the robotic arm could put down the scientific instruments.
"If Elysium Planitia was a salad, it would consist of tomato salad and ham – it does not dress," said Bruce Banerdt, principal investigator at NASA's Jet Propulsion Laboratory. – If it was an ice cream, it would be vanilla.
