The Genesis mission has already collected samples of the solar wind, material flowing outward from the Sun. The samples are on their way back to Earth. In another 30 days, the samples will be transported to the labs. Scientists will be able to compare the compositions of these samples with known compositions of the planets and help in the effort to understand how our solar system and its planets formed.

one wonders whether this is the closest we will get to the sun, or will we be able to get even 'closer'?

Yes for sure. Robotic missions can get a lot closer to sun.
