NASA Report Highlights Increasing Solar Activity

Rapid Summary

• Solar activity, which had been decreasing since the 1980s, reached a record low in 2008 but has been steadily increasing since then, according to a new NASA study published in The Astrophysical Journal Letters.
• Scientists had anticipated an extended period of historically low solar activity but were surprised by the reversal and rise in solar energetic events.
• Solar activity fluctuates in cycles of approximately 11 years and can have longer-term unpredictable trends lasting decades. Past periods of exceptionally low solar activity occurred between 1645-1715 and 1790-1830.
• Sunspots, areas associated with increased solar activity, are tied to phenomena such as solar flares and coronal mass ejections. These events impact spacecraft systems, astronaut safety, satellite communications, GPS navigation, and Earth’s power grids.
• Upcoming missions like NASA’s IMAP (Interstellar Mapping and Acceleration Probe) and NOAA’s SWFO-L1 aim to enhance space weather predictions critical for Moon-and-Mars exploration under NASA’s Artemis campaign.
• The rise in solar wind and magnetic field strength since 2008 was analyzed using heliospheric data from NASA spacecraft like ACE (Advanced Composition explorer) and Wind missions launched in the 1990s.

Indian Opinion Analysis

India stands to be significantly impacted by rising global solar activities due to its increasing reliance on satellite technology across critical sectors such as telecommunications, navigation systems (like GPS), disaster management alerts via INSAT satellites, climate monitoring programs aligned with ISRO’s initiatives on Earth observation missions. Strengthened efforts toward space weather monitoring will be crucial for safeguarding both civilian infrastructure like power grids-vulnerable during geomagnetic storms-and defense capacities relying on advanced satellites.

Collaborating internationally with organizations conducting space weather research might benefit India’s advancements through initiatives developed by ISRO or private aerospace firms venturing into sustainable extraterrestrial resource usage within lunar exploration plans envisaged directly fueled upcoming decades;} `Connectedfinal!*
