NASA’s Parker Solar Probe has achieved a historic milestone, safely completing its closest approach to the sun yet. On December 24, the spacecraft soared within a remarkable 3.8 million miles (6.1 million km) of the sun’s surface, entering its outer atmosphere known as the corona. This unprecedented maneuver allows scientists to gather crucial data about Earth’s nearest star.
The operations team at the Johns Hopkins Applied Physics Laboratory in Maryland confirmed the successful flyby shortly before midnight on Thursday, receiving a reassuring signal from the probe. NASA has reported that detailed telemetry data from the spacecraft is expected to be received on January 1.
Traveling at incredible speeds of up to 430,000 mph (692,000 kph), the Parker Solar Probe encounters intense conditions, with temperatures reaching as high as 1,800 degrees Fahrenheit (982 degrees Celsius). This mission grants scientists an opportunity to measure the intricate processes influencing solar dynamics.
With its groundbreaking observations, the Parker Solar Probe aims to unravel mysteries surrounding the heating of solar material, track the origins of the solar wind, and explore how energetic particles speed up to almost the speed of light. Launched in 2018, the probe has been ingeniously using planetary flybys of Venus to gradually shift its orbit closer to the sun, paving the way for scientific discoveries that could redefine our understanding of solar physics.
