NASA’s Parker Solar Probe makes its 15th close flyby of the sun this St. Patrick’s Day

NASA’s sun-touching Parker Solar Probe spacecraft will celebrate St. Patrick’s Day (March 17) by making another close approach to our star. While people all over Earth enjoy a cold beer, the spacecraft will brave blisteringly hot temperatures as high as 2,500 degrees Fahrenheit (1,400 degrees Celsius) as it makes its 15th close approach to the sun, or perihelion. 

According to NASA’s Parker Solar Probe website, (opens in new tab) the exact time of the close approach will be 4:30 p.m. EDT (2030 GMT) when the spacecraft comes to within around 5.3 million miles (8.5 million km) of the sun’s surface, the photosphere.
