NASA’s Parker Solar Probe has made a groundbreaking close approach to the Sun on December 24, 2024, coming within 6.1 million kilometers of the solar surface, a record distance for any spacecraft. Launched in august 2018, the probe aims to unlock the mysteries of solar phenomena, including solar storms that can disrupt Earth’s communications. During its rapid approach, reaching speeds of approximately 690,000 km/h, the probe’s thermal shield withstood extreme temperatures between 870 and 930 degrees Celsius, while its internal instruments maintained a stable temperature of around 29 degrees Celsius. This mission marks the first of three record-setting passes, with the next two scheduled for March 22 and June 19, 2025, as scientists seek to understand why the Sun’s corona is significantly hotter than its surface.

Time.news Interview with Dr. Emily Ross, solar Physicist
Editor: Thank you for joining us today, Dr. Ross. On December 24, 2024, NASAS Parker Solar Probe made a remarkable close approach to the Sun, coming within 6.1 million kilometers of its surface. Can you explain what this achievement means for solar science?
Dr. Ross: Absolutely! This historic close flyby sets a new record for proximity to the Sun for any spacecraft controlled from Earth. It’s a thrilling milestone for astrophysics. The Parker Solar Probe’s mission is crucial as it aims to explore and unlock the mysteries of solar phenomena, particularly solar storms that can impact Earth’s technological systems. By getting closer, we can gather unprecedented data that can enhance our understanding of the Sun’s behavior and its effects on our planet.
Editor: The Parker Solar Probe was launched in August 2018. Can you discuss what specific challenges the probe faces when getting so close to the Sun?
Dr. Ross: One of the biggest challenges is the extreme heat. During its recent approach, the probe reached speeds of about 690,000 kilometers per hour and had to withstand temperatures between 870 and 930 degrees celsius. Despite these conditions, the mission’s design includes a powerful thermal shield that protects its instruments. Remarkably, the probe’s internal systems manage to maintain a stable temperature of around 29 degrees celsius, which is critical for collecting accurate data.
Editor: That’s interesting! As we anticipate the next two close passes scheduled for March 22 and June 19, 2025, what key questions do scientists hope to answer through this research?
Dr. Ross: The paramount questions revolve around understanding why the Sun’s corona is significantly hotter than its surface. This is a perplexing aspect of solar science,as we’ve long recognized this phenomenon but have struggled to explain it thoroughly.By analyzing the solar atmosphere directly, scientists aim to determine the processes and events leading to the heating of the corona, and also the mechanisms behind solar flares and coronal mass ejections, which can disrupt communications and power systems on Earth.
Editor: How do you think these findings could impact everyday life on Earth,especially considering the potential for solar storms to disrupt interaction systems?
Dr. Ross: Insights gained from the Parker Solar Probe can improve our predictive models for solar storms, which is critically crucial for protecting our technology. Understanding solar activity helps us prepare for disturbances in communications, navigation systems, and even power grids. Better awareness allows us to mitigate the effects of these solar events, perhaps safeguarding not just technology but also lives.
Editor: for those interested in following the progress of the Parker solar Probe, what would you recommend they do to stay informed?
Dr. Ross: I suggest following updates through NASA’s official website and social media channels, where they share the latest discoveries and insights from the mission. There are also educational resources available for those keen on delving deeper into solar science and space exploration. Engaging with these materials can provide context for the ongoing research and its relevance to our daily lives.
Editor: Thank you, Dr. Ross, for sharing your insights on this groundbreaking mission. The Parker Solar Probe not only expands our understanding of the Sun but also prepares us for its profound effects on our planet.
Dr. Ross: Thank you for having me! It’s an exciting time for solar research, and I look forward to seeing what more we can learn from the Parker Solar Probe.
