What happened: Sun encounter reveals solar secrets
NASA‘s Parker Solar Probe is set to make its closest approach to the Sun on Christmas Eve, reaching approximately 3.8 million miles from its surface. This historic flyby is unprecedented, as no human-made object has ventured this close to a star.
The probe, travelling at an astonishing speed of about 430,000 miles per hour, was launched on August 12, 2018, to study the Sun’s complex dynamics, including solar corona and solar wind. During this approach, the spacecraft will rely on its 73 kg heat shield, designed to withstand temperatures up to 1,377°C.
Scientists anticipate receiving a confirmation signal on December 27, indicating that the probe successfully survived this critical flyby. Following this mission, two additional close approaches are scheduled for 2025, after which the team will evaluate the probe’s future trajectory.

Why it is important
The Parker Solar Probe‘s upcoming encounter is significant for several reasons. It promises to provide groundbreaking data on solar phenomena, enhancing our understanding of the Sun’s behaviour and its impact on space weather.
By studying the solar corona, which mysteriously exceeds the surface temperature of the Sun, researchers hope to uncover the mechanisms driving solar wind and its effects on Earth’s magnetosphere. This is particularly relevant, as solar activity can disrupt satellite communications and power grids.
Moreover, the mission continues to honour the legacy of Eugene Parker, an influential astrophysicist whose theories reshaped our understanding of stellar physics. By naming the probe after him, NASA acknowledges the importance of innovative ideas in advancing space exploration.
The Parker Solar Probe represents a leap forward in our quest to unravel the mysteries of our nearest star, potentially leading to technological advancements in various fields, from telecommunications to climate science. As we await the results from this mission, the knowledge gained could have far-reaching implications for both science and society.
