But each attempt has its own characteristics based on where spacecraft is going and what kind of science mission intends to gather.
On November 26, 2018, NASA will try to secure a new spacecraft on Mars. is a landlord dedicated to studying the deep interior of the planet – the first task ever to do it.
Landing on Mars is difficult
Only about 40 percent of the orders ever sent to Mars – of any space organization – has been successful. The United States is the only nation whose mission has survived a Mars landing. The thin atmosphere – just 1 percent of the earth – means that there is little friction to slow down a spacecraft.
Despite this, NASA has had a long and successful breakthrough on Mars. Since 1965, it has flown through, crooked, landed on and roved over the surface of the red planet.
InSight uses proven and true technology
In 2008, NASA’s Jet Propulsion Laboratory in Pasadena, California, successfully landed the Phoenix spacecraft at Mars’ North Pole. InSight is based on the Phoenix Spacecraft, both built by Lockheed Martin Space in Denver.
Despite the tweaks to its heat shield and parachute, the overall landing design is still very similar: After being separated from a cruise stage, an aerosol falls through the atmosphere. Parachute and retardocks slow down the spacecraft, and suspended legs absorb a little shock from the touchdown.
InSight lands on “the largest parking lot on Mars”
One of the benefits of InSights science instrument is that they can record equally valuable data wherever they are on the planet. It releases the mission from needing something more complicated than a flat, solid surface (preferably with few stones and stones). For the mission team, the landing site of Elysium Planitia is considered to be “the largest parking spot on Mars”.
InSight was built to land in a dust storm
InSights engineers have built a tough spacecraft that can move safely in a dust storm if needed. The spacecraft heat shield is designed to be thick enough to resist being “sandblasted” by dust.
The parachute has suspension lines tested to be stronger than Phoenix if it meets more air resistance due to atmospheric conditions expected during a dust storm.
The entrance, descent and landing sequence also have some flexibility to handle changing weather. The mission team will receive daily weather updates from NASA’s Mars Reconnaissance Orbiter in the days before they land so they can tweak when InSights parachute is triggered and when it uses radar to find the Mars surface.
After landing, InSight will provide new science of rocky planets
InSight teaches us the interior of planets as our own. The mission team hopes that by studying Mars deep inside, we can learn how other rocky worlds, including the earth and the moon, formed. Our home planet and Mars were made of the same primordial things more than 4.5 billion years ago, but then became quite different. Why did not they share the same fate?
In the case of rocky planets, we have only studied one in detail: the Earth. By comparing the Earth’s interior with Mars, InSights team members hope to better understand our solar system. What they learn can even help searching for earthlike exoplanets, reducing those who can support life.
So while InSight is a Mars mission, it’s also much more than a Mars mission.

A press release released today contains additional information about the assignment.
JPL manages InSight for NASA’s Research Council. InSight is part of NASA’s Discovery Program, run by the Agency’s Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including the cruise stage and landlords, and supports spacecraft operations for the mission.
A number of European partners, including the National Center of the United States of America, the Etudes Spatiales (CNES) and the German Space Center (DLR), support the InSight mission.
CNES provided the SEIS instrument Seismic Experiment for Interior Structure (SEIS), with significant contributions from the Max Planck Institute for Solar System Research (MPS) in Germany, Swiss Technical University (ETH) in Switzerland, Imperial College and Oxford University in the UK and JPL.
provided the DLR heat flow and physical properties package (HP3) with significant contributions from the Polish Space Organization (CBK) and Astronika in Poland. Spain’s Centro de Astrobiología (CAB) delivered the wind sensors.
