As for the mysterious impulses, astronomers are not sure what triggers them, but believe they are also related to how the solar wind interacts with Mars.
This study is one of six resulting from InSight's first year data, which can be viewed here. However, this is just the beginning of the InSight mission, which will complete its two-year main mission by the end of 2020.
Of particular interest are X-band radio measurements, which will show how Mars 'wobbles' as it rotates on its axis, which in turn will help reveal the true nature of the planet's core (solid or liquid?).
