A Daring Dive Toward the Sun
NASA has a special spacecraft called the Parker Solar Probe. It just did something no machine has ever done before. It flew closer to the Sun than any spacecraft in history!
The probe zoomed within about 6.1 million kilometres of the Sun's surface. That may sound far, but for a star as hot and huge as the Sun, it's incredibly close. Imagine standing right next to a giant campfire.
The Fastest Thing Humans Have Built
As the probe fell toward the Sun, the Sun's strong pull made it speed up. It reached about 692,000 kilometres per hour. That makes it the fastest human-made object ever!
At that speed, you could travel from New York to London in less than 30 seconds. It's far faster than any rocket, jet, or race car.
How Does It Not Melt?
The Sun is unbelievably hot, so the probe needs amazing protection. It has a thick shield made of special material called carbon foam.
This shield faces the Sun and can handle temperatures over 1,371°C. Behind the shield, the rest of the spacecraft stays cool and safe, almost like sitting in the shade on a hot day.
Why Fly So Close?
Scientists want to learn about the Sun's outer layer, called the corona. It's the glowing ring you can see during a solar eclipse.
The corona is a mystery because it is much hotter than the Sun's surface, even though it's farther away. By flying through it, the probe collects clues to help solve this puzzle.
Helping People on Earth
The Sun sometimes sends out bursts of energy called solar wind and solar storms. These can affect satellites, power lines, and even astronauts.
By studying the Sun up close, scientists can predict space weather better. That helps keep our technology safe back home on Earth.
