Will the interstellar comet 3I/ATLAS still exhibit a deuterium-to-hydrogen ratio at least 20× higher than Earth's oceans by end of June 2026?

🤖 Context

YES if peer‑reviewed measurements published by end of June 2026 confirm that 3I/ATLAS’s D/H ratio remains at least 20 times higher than Earth's ocean standard. NO otherwise (either published measurements report a lower ratio, or no peer‑reviewed confirmation appears by that date).
