Bengaluru-born astronomer Dr. Ramya Anche has been selected as principal investigator for NASA’s $20 million PUFFINS space telescope mission. Scheduled to launch in 2030, the SmallSat project will use ultraviolet spectropolarimetry to study nanometre-sized interstellar dust grains and decode how stars and planets form.
Dr. Ramya Anche to Lead NASA’s PUFFINS Mission
A Bengaluru-born astronomer will head a $20 million NASA space telescope mission designed to investigate the universe’s smallest building blocks. Dr. Ramya Anche, an assistant research professor at the University of Arizona’s Steward Observatory, has been named the principal investigator for PUFFINS, which stands for Polarimetry in the Ultraviolet to Find Features in INterStellar dust.
The initiative secured its funding under Astrophysics Pioneers programme, an agency framework specifically structured to give early-career scientists their first opportunity to lead a space mission. When she submitted the proposal last year, Anche was still a postdoctoral fellow rather than a faculty member.
Our proposal was selected under the Astrophysics Pioneers programme, which is specifically designed for early-career scientists leading a NASA mission for the first time. Notably, when I submitted the proposal last year, I was still a postdoctoral fellow, not yet a faculty member. The selection came with $20 million in funding to design, build and launch the telescope by 2030.

Investigating Nanometre-Sized Dust Grains with UV Light
The mission relies on a SmallSat carrying a telescope roughly 10 inches across to observe ultraviolet light from approximately 70 distant stars. By tracking how starlight changes as it travels through the interstellar medium, researchers hope to map cosmic particles that remain largely invisible to conventional instruments.
These targets are extremely small, measuring under 50 nanometres, or roughly the size of a common cold virus. While they appear insignificant, they govern how starlight travels and dictate how planets and stars eventually assemble.
PUFFINS will study the smallest grains of dust between the stars: particles roughly the size of a common cold virus. These grains are invisible to most telescopes, yet they play a critical role in how starlight travels through the galaxy, and ultimately in our understanding of how new stars and planets form.

To examine these tiny particles, PUFFINS employs ultraviolet spectropolarimetry. The technique is not entirely new, but its application from space has not been attempted in nearly thirty years. Earlier ultraviolet observations of interstellar dust polarizations relied on space-based instruments in the early 1990s, which examined only about 30 stars.

Global Collaboration Involving Arizona, McDonald, and Indian Institutions
The PUFFINS team currently encompasses roughly 40 individuals, including scientists, engineers, graduate students, and postdoctoral researchers. It operates as a joint venture between the University of Arizona, the McDonald Observatory, and an international network of institutions.
The institutional partners include two prominent Indian facilities: the Inter-University Centre for Astronomy and Astrophysics in Pune and the Indian Institute of Astrophysics in Bengaluru. Anche grew up nearby in Devanahalli, completed her education across local institutions, and eventually joined the Indian Institute of Astrophysics in 2012 before moving to the United States in 2021.
Bridging Gaps in Cosmic Evolution and Future Observatories
Beyond charting stellar nurseries and reflection nebulae, the mission addresses broader astrophysical questions. Dust polarization provides vital clues regarding galactic magnetic fields.
The Arizona team also envisions PUFFINS as a technological precursor to NASA’s proposed Habitable Worlds Observatory, utilizing the smaller mission to refine ultraviolet polarimetry capabilities for future decades.

The data it returns will fill a long-standing gap in our understanding of interstellar dust and by extension, the structure, and evolution of the universe.
