NASA has selected B-G Andersson to lead the PUFFINS mission, a research project designed to study interstellar dust using ultraviolet light. The mission, which is currently in the research-stage, aims to solve a mystery in interstellar physics that has persisted for over 50 years.
Why it matters
Interstellar dust is a critical component in the formation of stars and planets. By deploying new ultraviolet spectropolarimetry, researchers hope to decode the chemical and structural properties of this material in space.
The mission marks the return of spectropolarimetry to space for the first time in three decades. It will utilize ultraviolet light to probe interstellar dust, a field that has remained constrained by ground-based observation since the 1949 discovery of interstellar polarization.
The players
B-G Andersson
The science principal investigator for PUFFINS and assistant director for research support at McDonald Observatory.
Ramya Anche
The principal investigator for PUFFINS and an assistant research professor at the University of Arizona's Steward Observatory.
McDonald Observatory
A major astronomical research facility operated by UT Austin that provides ground-based observation support.
Steward Observatory
The research division of the University of Arizona focused on observational and theoretical astrophysics.
The details
PUFFINS will use spectropolarimetry — the measurement of light polarization across a spectrum of wavelengths — to analyze how ultraviolet light interacts with interstellar dust. By observing the gas surrounding these dust grains, researchers can map the physical environment that drives star and planet formation. Data from this orbital mission will be interpreted alongside ground-based observations conducted at the McDonald Observatory.

The Tech Race
This mission represents a significant effort to revive orbital spectropolarimetry, a technology that has not been deployed in space for three decades. It seeks to resolve a 50-year-old mystery regarding how dust influences star and planet formation.
The PUFFINS mission is currently in the planning stages with an anticipated launch in 2030. Astronomers and researchers will gain new primary data from space that aims to clarify the physical processes behind how stars form.
The takeaway
The PUFFINS mission targets a half-century-old mystery about the role of interstellar dust in planetary systems. Interested readers should track the 2030 launch schedule for updates on the deployment of its ultraviolet spectropolarimetry instrument.
