InSight is also the first NASA interplanetary mission to launch from the West Coast, particularly from Space Launch Complex 3E at the US Air Force Vandenberg Base. After it arrives on the planet on November 26th, (around 3PM Eastern time), it will deploy a seismometer and a heat probe to detect Marsquakes and monitor the flow of heat. Its findings will help us better understand what's underneath the Martian surface, such as how thick its crust is. The data it sends back could also shed light on how rocky planets and their natural satellites are formed -- including our own.

LIFTOFF! Humanity's next mission to Mars has left the pad! @NASAInSight heads into space for a ~6 month journey to Mars where it will take the planet's vital signs and help us understand how rocky planets formed. Watch: https://t.co/SA1B0Dglms pic.twitter.com/wBqFc47L5p — NASA (@NASA) May 5, 2018
