On November 26, 2018, NASA's InSight mission landed in Elysium Planitia, Mars, and installed the first geophysical station on the planet. InSight's primary payload consists of a seismometer, a heat flow probe, and a radio tracking experiment to determine the planet's rotational state. In addition, the lander is equipped with a robotic arm that has been used to deploy the seismometer and heat flow probe, two cameras, a radiometer, and an atmospheric and magnetic field package. InSight's primary objectives are to determine the interior structure, composition, and thermal state of Mars, as well as constrain present-day seismicity and impact cratering rates. While the heat flow probe faces difficulties in emplacing sensors to the target depth of 5 m, the seismometer has been successfully installed. Here we will provide a mission overview and report on results obtained during the first year of operations on Mars.
