One is going to fly two of NASA's WB-57 jets to chase the eclipse with telescopes mounted in the nose cone and under the wings to make observations of the solar corona in infrared and other wavelengths.
The other is going to deploy 35 teams of amateurs across the eclipse path, giving them telescopes that can measure the polarization of light from the ground.
There are a lot of open questions about the sun even though it is our star. The corona is millions of degrees, but it's the atmosphere of the star. Why is the atmosphere hotter than the surface? This is something that's counterintuitive.
