There is an ancient Chinese story about a giant man named Kua Fu who chases the sun. He drains the Yellow and Wei rivers during his race and finally dies of delydration(脱水). His failure has reminded people of the unstoppable power of the sun for centuries. And yet, scientists throughout history have tried to better understand the most important star in our sky. On Aug 12, NASA launched the Parker Solar Probe(探测器), marking the start of its trip to the sun.

The probe itself is almost as big as a car and needed the help of a powerful rocket to escape Earth’s orbit, change direction and reach the sun. In order to reach the sun, the probe must complete seven flybys of Venus, using the power of the planet’s gravity to change its path, sending it toward the sun. But that’s not the only difficult part of the journey. As the probe approaches the sun’s corona(日冕), it will have to bear temperatures reaching 1,400℃, as well as deal with serious radiation. So how will the probe survive?

According to NASA, a special shield has been used, which is a special 11.5 cm-thick carbon-composite shield that will be positioned between the probe and the sun’s corona. It’s advanced technology like this that will make the probe’s trip to the sun much smoother. If everything goes as planned the probe will reach a speed of 692,018 kilometers per hour as it moves around the sun, setting a new record for the fastest man-made object in history, NBC noted. It will fly close to the sun 24 times between 2018 and 2025. NBC added.
