Enter: Solar Probe Plus (SPP), a NASA mission in development at the Johns Hopkins University Applied Physics Laboratory. This robotic explorer will venture closer to the Sun than any other probe before it, flying through its corona—the searing atmosphere surrounding the star—for the first time in history. It will brave both fiery and freezing temperatures, travel faster than anything ever made by humans, and deliver the most intimate glimpse of our star—and the forceful solar wind it emits—in spaceflight history.
