NASA selects Bengaluru-born astronomer Ramya Anche to lead $20m PUFFINS space mission

Bengaluru-born astronomer Dr Ramya Anche has been appointed Principal Investigator to lead a $20 million NASA space telescope mission aimed at decoding how interstellar dust builds stars and planets.

The mission, named PUFFINS—short for Polarimetry in the Ultraviolet to Find Features in INterStellar dust—was selected under the US space agency's Astrophysics Pioneers programme. Targeted for launch in 2030, the project places Indian-trained scientific talent at the forefront of international space exploration.

Dr Anche, an assistant research professor at the University of Arizona's Steward Observatory, grew up in Devanahalli near Bengaluru. She completed her studies across institutions in the city before joining the Indian Institute of Astrophysics (IIA) in 2012, building foundational expertise that has now carried her to the helm of a major space initiative.

What the PUFFINS mission will study

The mission employs a 10-inch telescope aboard a SmallSat to observe ultraviolet light emitted by around 70 distant stars. It seeks to answer a 50-year-old astrophysical puzzle regarding the mechanics of cosmic dust.

"PUFFINS will study the smallest grains of dust between the stars: particles roughly the size of a common cold virus," Dr Anche explained in an interview with The Hindu. "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 observe these microscopic particles, the mission will deploy UV spectropolarimetry, an observational technique that has not been conducted from space in three decades. The measurements are expected to plug critical gaps in human knowledge surrounding interstellar material and the wider structure and evolution of the universe.

Global collaboration including Indian institutes

The initiative brings together roughly 40 researchers, including senior scientists, engineers, graduate students, and postdoctoral fellows. Reflecting India's growing stature in space science collaborations, two premier domestic institutions are formally embedded in the project team.

How the mission was selected

The selection followed a rigorous international competition conducted through NASA's Research Opportunities in Space and Earth Science (ROSES) solicitation. Competing teams submitted comprehensive blueprints covering scientific targets, mission architecture, and instrument fabrication.

Dr Anche prepared and submitted the winning proposal while still working as a postdoctoral fellow, ahead of her transition to a faculty position. The Astrophysics Pioneers programme explicitly targets early-career scientists tasked with steering a NASA mission for the first time.

The resulting award grants $20 million in funding to oversee the entire life cycle of the telescope, including its engineering, construction, and scheduled launch by the end of the decade.
