The article celebrates the 30th anniversary of the ESA/NASA Solar-Heliospheric Observatory (SOHO), launched on December 2, 1995. SOHO, stationed 1.5 million kilometers from Earth, offers a continuous view of the Sun and has provided invaluable data across nearly three solar cycles.
Key highlights include:
-
Mission Challenges: Despite facing critical errors, including a loss of control and gyroscope failures, SOHO adapted through innovative software updates, enhancing solar research.
-
Scientific Contributions: SOHO has revolutionized solar science, enabling real-time monitoring of solar activity and improving forecasts of hazardous solar storms.
-
Data Legacy: SOHO’s extensive data supports ongoing studies; research indicates the Sun’s energy output is stable, affecting Earth’s climate minimally.
-
Comet Discoveries: Unintentionally functioning as a comet hunter, SOHO has discovered over 5,000 comets, largely thanks to citizen scientists.
- Future Impact: SOHO’s achievements inspire new solar missions like ESA’s Solar Orbiter and NASA’s Parker Solar Probe, ensuring its legacy continues to influence solar science for years to come.
Overall, the article emphasizes SOHO’s significance in advancing our understanding of solar dynamics and its collaborative efforts between NASA and ESA.
