SPHEREx
NASA all-sky near-infrared spectrophotometric survey (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer). Per src-loeb-panspermia-impact-survival-2026-03, avi-loeb cites SPHEREx as having detected organic molecules on interstellar object 3i-atlas — observational support for treating interstellar objects as targets of astrobiological interest.
Cross-mission 3I/ATLAS compositional analysis (2025–2026)
SPHEREx contributed to a cross-mission analysis of 3i-atlas’s volatile production rates. Combined with NASA’s MAVEN Mars orbiter and James Webb Space Telescope, SPHEREx data revealed that 3I/ATLAS’s water, CO₂, and carbon monoxide production rates differ substantially from solar-system comets — an interstellar-origin signature accessible only through multi-mission data fusion (src-nasa-3i-atlas-open-data-2026-03).
