NASA dixit:

“NASA’s InSight mission launched from Vandenberg Air Force Base for Mars on May 5, 2018—the first interplanetary launch from the West Coast. InSight is expected to land on the Red Planet on November 26, 2018. More than a mission to Mars, InSight will help scientists understand the formation and early evolution of all rocky planets, including Earth.”

NASA dixit:

“All of NASA’s interplanetary launches to date have been from Kennedy Space Center in Cape Canaveral, Florida, in part because the physics of launching off the East Coast are better for journeys to other planets. However, InSight will break the mold by launching from Vandenberg Air Force Base in California. It will be the first launch to another planet from the West Coast. A whole new region of the country will get to see an interplanetary launch when InSight rockets into the sky. On a clear day, the launch may be visible from Santa Maria, California to San Diego, California.

Weather permitting, InSight’s pre-dawn launch (4:05 a.m.) may be visible for more than 10 million Californians without a need for them to drive to a special location. Just wake up early, check the InSight Website for assurance the launch is still on schedule, go outside, look at the western sky, marvel at the rocket’s flare as it travels southward, and cheer InSight bon voyage to Mars. The launch window is May 5 through June 8, 2018.”

NASA JPL dixit:

“Starting next year, scientists will get their first look deep below the surface of Mars. That’s when NASA will send the first robotic lander dedicated to exploring the planet’s subsurface. InSight, which stands for Interior Exploration using Seismic Investigations, will study marsquakes to learn about the Martian crust, mantle and core.

When rocks crack or shift, they give off seismic waves that bounce throughout a planet. These waves, better known as quakes, travel at different speeds depending on the geologic material they travel through. Seismometers, like InSight’s SEIS instrument, measure the size, frequency and speed of these quakes, offering scientists a snapshot of the material they pass through.

Mars’ geologic record includes lighter rocks and minerals — which rose from the planet’s interior to form the Martian crust — and heavier rocks and minerals that sank to form the Martian mantle and core. By learning about the layering of these materials, scientists can explain why some rocky planets turn into an “Earth” rather than a “Mars” or “Venus” — a factor that is essential to understanding where life can appear in the universe.

Each time a quake happens on Mars, it will give InSight a “snapshot” of the planet’s interior. The InSight team estimates the spacecraft will see between a couple dozen to several hundred quakes over the course of the mission. Small meteorites, which pass through the thin Martian atmosphere on a regular basis, will also serve as seismic “snapshots.” One challenge will be getting a complete look at Mars using only one location. Most seismology on Earth takes measurements from multiple stations. InSight will have the planet’s only seismometer, requiring scientists to parse the data in creative ways.

InSight will measure more than seismology. The Doppler shift from a radio signal on the lander can reveal whether the planet’s core is still molten; a self-burrowing probe is designed to measure heat from the interior. Wind, pressure and temperature sensors will allow scientists to subtract vibrational “noise” caused by weather. Combining all this data will give us the most complete picture of Mars yet.”
