NASA has set a new launch opportunity, beginning May 5, 2018, for the InSight mission to Mars. This artist&#39;s concept depicts the InSight lander on Mars after the lander&#39;s robotic arm has deployed a seismometer and a heat probe directly onto the ground. InSight is the first mission dedicated to investigating the deep interior of Mars. The findings will advance understanding of how all rocky planets, including Earth, formed and evolved.
