Nasa makes history with closest-ever approach to Sun

On December 24th, 2024, the world-renowned National Aeronautics and Space Administration (NASA)'s Solar Probe Parker passed only 3.8 million miles above the surface of the Sun. In comparison, the Sun is nearly 93 million miles away from the Earth, putting into perspective the degree of accomplishment this probe has done. Furthermore, this feat made history with the closest-ever encounter with the Sun, marking a significant jump from the first probe, Sputnik 1 (which traveled only 43 million miles). Not only does this mark a significant advancement in space travel technology, but it also presents countless opportunities for further exploration. Specifically, this probe withstood soaring temperatures of 1400 degrees Celsius (2552 degrees Fahrenheit) and still managed to travel at the astonishing speed of 432,000 miles per hour, a whopping 563 times faster than the speed of sound.

According to NASA officials, the Parker probe was designed with an enduring 4.5 inch thick carbon-composite shield that acted as an expansive heat protector (that prevented the Sun from frying any electronics) while simultaneously keeping the interior space cooler. Additionally, the probe was equipped with 2 solar panels that generated about 343 watts of power to keep itself functioning. It collected this energy through the absorption of solar radiation from solar arrays ( which were suspended on two separate wings of the probe) that either retracted or extended to keep a proper angle that faced the sun. The probe was painted by ceramic paint to reflect excess heat, the probe was aptly able maintain its structure.
