00:00NASA has done it again, history made with the closest ever approach to the sun.
00:05On Christmas Eve, the Parker Solar Probe achieved what seemed impossible.
00:09It survived a scorching flyby, just 3.8 million miles from the sun's surface.
00:15That's like being just 4 centimeters away if the sun and Earth were a meter apart.
00:19Traveling at a jaw-dropping 430,000 miles per hour,
00:23this spacecraft faced temperatures hotter than 1,800 degrees Fahrenheit,
00:28protected only by its cutting-edge carbon composite shield.
00:32But why take such a risk?
00:34The mission is unlocking mysteries of the sun's corona,
00:37a region that's millions of degrees hotter than the sun's surface.
00:41How does that even happen?
00:43Scientists are eager to find out.
00:45And it's not just about curiosity.
00:48Solar wind from the sun can disrupt power grids, satellites,
00:51and even communication systems here on Earth.
00:54By studying the sun up close, NASA is helping protect our modern world.
00:58After days of nerve-wracking silence, a signal confirmed the probe survived.
01:04Parker Solar Probe is not just a mission.
01:07It's a leap for humanity in understanding our sun, the very heart of our solar system.
