This conference will bring together experts and enthusiasts of infrared spectroscopy to discuss the vast scientific potential unlocked by space-based infrared observations. From unraveling galaxy evolution across cosmic time to revealing the chemical compositions of star-forming regions and planetary systems, space spectroscopy offers an unparalleled window into the universe. Missions such as JWST, Euclid, SPHEREx, Roman and Ariel are, or soon will be, revolutionizing our ability to study the faintest and most distant objects, or acquire spectra orders of magnitude faster than previous telescopes.

The aim of the conference is to highlight the scientific breakthroughs enabled by these missions and explore synergies across distinct fields—from cosmology to planetary science—through shared methodologies or multi-purpose data sets. It will also strive to address the community's research and collaboration needs, especially regarding large and complex datasets, while promoting the use of advanced data analysis techniques. An additional focus will be on exploring strategies to optimize future observational efforts, ensuring maximum scientific return from these missions.
