 Solar Orbiter will actually have remote sensing and in situ data, so we'll be able to sample the inner part of the atmosphere of the sun called the corona. So we'll be getting composition measurements of this area where solar wind occurs. And that's extremely important for understanding how the solar wind is generated, what's happening in the corona in this extended atmosphere of the sun. So getting close up allows us to sample and view the sun from this region where we haven't been able to before.
