    For the first time in history, a spacecraft has touched the Sun. NASA's Parker Solar Probe has now flown through the Sun's upper atmosphere -- the corona -- and sampled particles and magnetic fields there. Launched in 2018 to explore the mysteries of the Sun, the Parker Solar Probe has, so far, completed nine full orbits of the Sun. Before its prime mission ends in 2025, it will complete another 15 orbits.
