Chandrayaan-2's CHACE [Chandra's Atmospheric Composition Explorer-2] payload made its first ever observations of the effects of a coronal mass ejection (CME) on the lunar exosphere.

KEY CONTRIBUTIONS
1] CHACE-2 conducted in-situ mass spectrometric measurements of the moon's exosphere and analyzed neutral particles and mapped their spatial and temporal variations.
2] It detected variations in Argon-40, (noble gas produced by radioactive decay of K-40 in the lunar interior). This detection helped scientists understand how Ar gases released from the lunar surface vary with local time, latitude and geological features.
3] The payload studied how solar radiation, solar wind and micrometeorite impacts affect the exosphere. It provided insights into surface-exosphere coupling, showing how solar activity influences the moon's atmosphere.
4] CHACE-2 as compared with earlier CHACE had better sensitivity and longer operational time allowing continuous observation and more accurate profiling of exospheric dynamics.

CHACE-2 significantly advanced India's lunar atmospheric research by revealing dynamic processes in the Moon's exosphere, thereby aiding future lunar exploration and comparative planetary studies.

Strong technical content with good scientific terminology and specific examples like Argon-40 detection. The answer effectively covers most demands but could better integrate the quantitative space weather findings mentioned in the introduction.
