In. Sight Mission to Mars Mission objectives: The In. Sight mission will conduct six science investigations on and below the surface of Mars to uncover the evolutionary history that shaped all of the rocky planets in the inner solar system. It will: • Determine the size, composition, physical state (liquid/solid) of the Martian core • Determine thickness and structure of the Martian crust • Determine the composition and structure of the Martian mantle • Determine thermal state of Mars' interior • Measure the magnitude, rate and geographical distribution of Mars' internal seismic activity • Measure the rate of meteorite impacts on the surface of Mars Next Slide

In. Sight Mission to Mars By using sophisticated instruments, In. Sight will delve deep beneath the surface of Mars, detecting the fingerprints of the processes of terrestrial planet formation, as well as measuring the planet's "vital signs“: • Its "pulse" (seismology) • Its "temperature" (heat flow probe) • Its "reflexes" (precision tracking). Mars will get its first “checkup” in more than 4. 5 billion years. Next Slide

In. Sight Mission to Mars The In. Sight Lander will carry three instruments to the surface of Mars: 1. SEIS: To capture Mars' pulse, or its internal activity. 2. HP 3: To take Mars' temperature, a key indicator of planetary evolution. 3. Rise: To track Mars' reflexes, or the way it wobbles when it is pulled by the Sun. More Information Next Slide

In. Sight Mission to Mars Insight will use two cameras: In. Sight will incorporate a camera, similar to the "Navcam" engineering cameras onboard the Mars Exploration Rovers (MER). A second similar camera will be used, with a wide-angle 120 -degree field of view lens like the "Hazcam" cameras on MER. More Information Next Slide

In. Sight Mission to Mars In. Sight is more than a Mars mission - it is a terrestrial planet explorer that will address one of the most fundamental issues of planetary and solar system science - understanding the processes that shaped the rocky planets of the inner solar system (Earth top and Mars bottom) more than four billion years ago.

In. Sight Mission to Mars Mission overview: • In. Sight's primary objective will be

In. Sight Mission to Mars Mission overview: • In. Sight's primary objective will be to uncover how a rocky body forms and evolves to become a planet. Generally, a rocky body begins its formation through a process called accretion. As the body increases in size, its interior heats up and melts. As it subsequently cools and recrystallizes it evolves into what we know today as a terrestrial planet, containing a core, mantle and crust. While all of the terrestrial planets share similar structures and their bulk compositions are roughly the same as the meteoritic material from which they were formed, they are by no means uniform. Each of the terrestrial planets reached their current formation and structure through a process known as differentiation, which is poorly understood. In. Sight's goal will be to solve the mystery of differentiation in planetary formation - and to bridge the gap of understanding that lies between accretion, and the final formation of a terrestrial planet's core, mantle, and crust. • The mission's secondary objective is to conduct an in-depth study of tectonic activity and meteorite impacts on Mars, both of which could provide valuable knowledge about such processes on Earth. Mars’ internal structure Return

In. Sight Mission to Mars has the same basic internal structure as the Earth

In. Sight Mission to Mars has the same basic internal structure as the Earth and other terrestrial (rocky) planets. It is large enough to have pressures equivalent to those throughout the Earth's upper mantle, and it has a core with a similar fraction of its mass. This diagram shows the depths at which high pressures cause certain minerals to transform to higher-density crystal structures. The size of Mars indicates that it must have undergone many of the same separation and crystallization processes that formed the Earth's crust and core during early planetary formation. Return

In. Sight Mission to Mars The In. Sight Lander will carry three instruments to the surface of Mars: 1. SEIS: To capture Mars' pulse, or its internal activity, In. Sight will carry a seismometer called SEIS to the surface of the Red Planet. SEIS will take precise measurements of quakes and other internal activity on Mars to better understand the planet's history and structure. 2. HP 3: To take Mars' temperature, a key indicator of planetary evolution, In. Sight will deploy a heat flow probe on the surface of Mars. The instrument, known as HP 3, will hammer five meters into the Martian subsurface, deeper than all previous arms, scoops, drills and probes, to learn how much heat is coming from Mars' interior and reveal the planet's thermal history. Another instrument Return

In. Sight Mission to Mars 3. Rise: To track Mars' reflexes, or the way it wobbles when it is pulled by the Sun, an investigation called RISE will precisely measure the Doppler shift and ranging of radio communications sent between the In. Sight lander and Earth. By tracking wobble, scientists can determine the distribution of the Red Planet's internal structures and better understand how the planet is built. Return

In. Sight Mission to Mars Cameras: In. Sight will incorporate a camera, similar to the "Navcam" engineering cameras onboard the Mars Exploration Rovers (MER), mounted on the arm of the lander that will serve to capture black and white images of the instruments on the lander's deck and a 3 -D view of the ground where the seismometer and heat flow probe will be placed. It will then be used to help engineers and scientists guide the deployment of the instruments to the ground. With a 45 -degree field of view, the camera will also provide a panoramic view of the terrain surrounding the landing site. A second similar camera, with a wide-angle 120 degree field of view lens like the "Hazcam" cameras on MER, will be mounted under the edge of the lander's deck and will provide a complementary view of the instrument deployment area.
