Today, December 24, one evening before Christmas, NASA’s Parker Solar Probe will pass closest to the Sun. According to Indian time, at 5:10 p.m., Parker will be just 61 lakh km from the Sun. It will be the first man-made object to come this close to the Sun.
According to the NYT report, it is 7 times closer than any previous mission to the sun. While passing through the outer atmosphere of the Sun, Parker’s speed will be more than 6.9 lakh km/hour. This is the highest speed ever achieved by a man-made object and will beat its previous record.
According to Nikki Fox of NASA’s science mission, so far nothing has passed through a star’s atmosphere. This will be the first time an object has passed through the star’s atmosphere. Parker will remain in the sun’s atmosphere for the next 3 days.
The temperature will be above 1000 as it passes close to the Sun. So far, Parker Solar Probe has reached the closest point to the Sun through 21 Sun flybys. This region is called perihelion. Parker’s temperature will exceed 1,000 degrees Celsius as it passes near the Sun.
During this time, it will slip through the sun’s atmosphere. The Sun is currently in its most active state. This is called solar maximum. Parker will send information about his trip to Earth on December 27. Until then, he will remain out of contact.
Next year, also in 2025, it will pass close to the Sun twice. This mission will end next year. However, there is still fuel left for the next few years. But it will never come this close to the sun again.

Parker was launched 6 years ago. Parker Solar Probe was launched by NASA on August 12, 2018. It was launched with the aim of closely studying the corona, the outer atmosphere of the Sun. Through this, efforts are being made to understand the solar wind system.
It is also named after solar scientist Eugene Parker. Parker was the first to provide information on solar winds. Eugene Parker died in 2022. For the first time, a spacecraft is named after a scientist during his lifetime.
Parker Solar Probe flew close to the sun for the first time in 2021. For the first time in history, a spacecraft passed so close to the Sun. It was designed to pass close to the sun a total of 24 times. Today, Parker will pass near the sun for the 22nd time.
To protect against the heat of the sun, it has been equipped with a 4.5-inch thick carbon composite heat shield. ,
