Why in news
Researchers at the Okinawa Institute of Science and Technology (OIST) linked a 13th-century Japanese diary entry to a massive solar particle event to help plan future space missions.
Background
Fujiwara no Teika's 1204 CE diary entry regarding 'red lights' was correlated with increased carbon-14 levels in ancient cypress trees. The study identifies shorter, erratic solar cycles that impact space weather data for NASA's Artemis missions.
Facts for Prelims
- S&TOIST: Okinawa Institute of Science and Technology conducted the research
- FactCarbon-14 levels in ancient cypress trees were used as indicators of solar particle events
- S&TArtemis missions: NASA's lunar exploration program utilizing this space weather data
- FactThe diary entry by Fujiwara no Teika dates back to 1204 CE
For Mains
Q. Discuss how historical data and paleoclimatology can enhance our understanding of space weather and ensure the safety of deep space exploration missions.
Dimensions to cover in your answer
- Data integration: Combining paleoclimatological records with modern satellite telemetry to model erratic solar cycles
- Astronaut safety: Mitigating risks of Extreme Solar Particle Events (ESPEs) during long-duration lunar and Martian missions
Keywords: Space Weather · Solar Particle Events · Paleoclimatology · Artemis Missions · Carbon-14 Dating
