NASA scientist discusses Parker's journey to the sun

Sixty years ago, NASA set an out-of-this-world goal: to touch our sun. Sending a spacecraft to the fiery star at the center of our solar system is no small feat. From engineering a spacecraft that could hurtle 430,000 mph through space to agreeing on what kinds of data it would capture, there was a lot to sort out. A half-century in the making, Parker Solar Probe finally launched in 2018. Now, three years later, it has touched the sun.
