Hi Sophia,
In 2018 NASA will be launching the Solar Probe Plus mission (
https://science.nasa.gov/missions/solar-probe). This spacecraft will go closer to the sun than any spacecraft has ever gone before, sampling and imaging the hot solar wind as it flows away from the sun. It will get 3.7 million miles from the solar surface, which sounds like a lot, but on solar system terms is pretty close-by, and the intense brightness of the sun makes that very difficult.
Another solar space mission, Solar Orbiter, is scheduled to launch in 2019. This is a European Space Agency mission, but NASA is involved too. Solar Orbiter (
https://science.nasa.gov/...sions/solar-orbiter) will not get as close to the Sun as Solar Probe Plus, but it will get closer than the planet Mercury. It will also move out of the plane of Earth's orbit (the "ecliptic") and be able to image the area around the Sun's poles, which is hard to do from Earth's orbit.
