NASA Awards $20 Million to PUFFINS Mission Led by Indian-Origin Scientist
NASA has selected Dr. Ramya Manjunath Anche, an assistant research professor at the University of Arizona’s Steward Observatory, as the principal investigator for a $20 million mission targeting the universe’s smallest interstellar dust grains, Firstpost reported. The initiative, named PUFFINS (Polarimetry in the Ultraviolet to Find Features in INterStellar dust), received its funding under NASA’s Astrophysics Pioneers programme and is targeted for launch in 2030.
Small Satellite and Ultraviolet Telescope Target 70 Stars
For its observations of ultraviolet light originating from approximately 70 stars, PUFFINS will deploy a compact satellite equipped with a telescope featuring an aperture roughly 10 inches wide. By analyzing how starlight changes as it travels through cosmic dust, researchers plan to map microscopic grains that have remained difficult to study using conventional telescopes. Visible light helps scientists study grains around 0.1 microns in size, but examining smaller particles around 0.05 microns requires ultraviolet observations. According to Anche, ultraviolet light is the key to unlocking these smaller components.
Silicate and Carbonaceous Grains Shape Planetary Systems
Interstellar dust consists largely of silicates resembling sand and carbonaceous grains resembling soot, playing an important role in how stars, planets, and planetary systems form. When a star forms, it is surrounded by a thick ring of gas and dust, which can eventually develop into planets, asteroid belts, and rings. Anche noted that understanding this material is essential for investigating how life might emerge on planets orbiting stars beyond our Sun. Because dust is a critical component of how planetary systems and eventually life form, researchers cannot separate the question of life in the universe from the study of dust.

Ultraviolet Polarimetry Distinguishes Dust Types and Magnetic Fields
The mission will use a technique called polarimetry, which involves measuring the polarisation of starlight as it passes through dust grains aligned by the galaxy’s magnetic field. Silicate grains align efficiently with magnetic fields, whereas carbonaceous grains do not, allowing scientists to distinguish between different types of dust. This ultraviolet polarimetry approach is an approach that Anche said has not been used for this purpose in three decades. In addition to aiding studies of stellar formation, charting dust polarisation enables scientists to subtract foreground noise from the cosmic microwave background—a crucial step for detecting faint B-mode polarisation signatures that could offer proof of primordial gravitational waves and shed light on the universe’s earliest epochs.
Inspiration Drawn from Kalpana Chawla
Anche’s journey into astronomy began during her school years near Bengaluru, where reading about Indian-born astronaut Kalpana Chawla sparked her interest in space. The mission focuses on tiny particles that are fundamental to cosmic evolution, connecting her early inspiration to current efforts to understand the origins of planets and the cosmos.
