Professor Kuljeet Kaur Marhas, a senior scientist at the Physical Research Laboratory (PRL) in Ahmedabad, has made history by becoming the first Indian woman to be elected as a Fellow of the Meteoritical Society for 2026. This fellowship is considered one of the most prestigious international honours in the fields of meteoritics, cosmochemistry, and planetary science, reserved for those who have distinguished themselves through groundbreaking contributions to allied sciences. Operating under the administrative control of the Department of Space, she is only the third Indian scientist to receive this global distinction, following the late geophysicist Devendra Lal and renowned planetary scientist Jitendra Nath Goswami.
A Historic Distinction in Planetary Science
The election of Professor Kuljeet Kaur Marhas as a Fellow of the Meteoritical Society represents a landmark moment for India’s scientific community. As the first Indian woman scientist to achieve this honour, her election highlights the growing role and leadership of Indian women in specialized space research. This fellowship is extremely selective, meaning her recognition reflects decades of high-impact research.
She joins an elite global group of scientists who study the origin, history, and composition of planetary bodies. Prior to her election in 2026, only two other Indian scientists had ever received this fellowship. By joining their ranks, Professor Marhas has cemented India’s position on the global map of cosmochemistry and meteoritics research.
Research Focus: Tracing the Early Solar System’s Evolution
Professor Marhas is internationally recognized for her extensive research into the origin and early evolution of the Solar System. Her work primarily involves analyzing primitive extraterrestrial materials to reconstruct cosmic events that took place more than 4.5 billion years ago. By studying these ancient samples, she deciphers the chemical and physical processes that governed the birth of the Sun and the planets.
Her investigations focus on primitive cosmic materials such as presolar grains, which are microscopic dust particles formed in the atmospheres of dying stars before our Solar System existed. These grains offer a direct window into stellar evolution and nucleosynthesis. Additionally, she analyzes Calcium-Aluminium-rich inclusions (CAIs), which are the oldest solid objects formed within the early solar nebula, serving as precise time capsules of the Solar System’s oldest thermal events. She also studies chondrules and meteorites to understand the mixing and cooling of materials in the early protoplanetary disk.
To examine these microscopic samples, Professor Marhas relies on advanced micro-analytical instrumentation. She played a pivotal role in establishing the high-resolution Nano Secondary Ion Mass Spectrometry (NanoSIMS) facility at PRL. This cutting-edge instrument uses a high-intensity primary ion beam to sputter the surface of a sample, allowing researchers to measure the isotopic composition of elements at the sub-micrometer scale. Through this precise isotopic mapping, she extracts “cosmic fingerprints” that show how elements were distributed and mixed during the Solar System’s formative years.
Pioneering Indian Fellows of the Meteoritical Society
Professor Marhas joins two legendary Indian scientists in receiving this international distinction. The first Indian scientist to be elected as a Fellow of the Meteoritical Society was the late geophysicist Devendra Lal in 1970. A towering figure in Indian science, Devendra Lal served as the Director of PRL from 1972 to 1983. His pioneering research spanned cosmic rays, oceanography, and meteoritics, including the analysis of lunar samples brought back by the historic Apollo missions. His globally recognized contributions earned him the prestigious Leonard Medal in 1987, which is the highest scientific honour awarded by the Meteoritical Society.
The second Indian scientist to receive the fellowship was Jitendra Nath Goswami, widely recognized as a cornerstone of modern Indian planetary exploration. Popularly known as the Moon Man of India, he served as the Principal Scientist for the landmark Chandrayaan-1 mission, which discovered water molecules on the Moon. He also served as the Director of PRL and contributed significantly to the planning of Chandrayaan-2 and the Mars Orbiter Mission, also known as Mangalyaan. His research on the early Solar System, cosmic ray records in meteorites, and isotopic anomalies earned him the fellowship. The fact that all three Indian fellows are associated with the Physical Research Laboratory highlights the institution’s long-standing leadership in space sciences.
The Meteoritical Society and its Fellowship
Founded in 1933, the Meteoritical Society is an international scholarly organization dedicated to the promotion of research and education in planetary science. While the society’s primary focus is the study of meteorites and other extraterrestrial materials, its broader scope encompasses the investigation of planetary systems, cosmochemistry, and the early history of the Solar System. Representing scientists and enthusiasts from over 50 countries, the society serves as the primary global forum for planetary materials research.
The title of Fellow is one of the most prestigious distinctions conferred by the society. To maintain its high standards of excellence, the election of new Fellows is governed by strict rules. Elections are held only in even-numbered years, and the number of members elected as Fellows in any given election year cannot exceed 1% of the total membership of the society. Candidates are nominated by their peers, and their scientific contributions are thoroughly evaluated by the Leonard Medal Committee before a final selection is recommended to the society’s Council. This rigorous process ensures that the fellowship remains a rare and highly respected honour worldwide.
Physical Research Laboratory: India’s Space Science Pioneer
The Physical Research Laboratory (PRL) is widely recognized as the cradle of space sciences in India. Established in 1947 by the visionary scientist Dr. Vikram Sarabhai, the institute initially began its operations in Ahmedabad, Gujarat, focusing on cosmic rays and the physics of the upper atmosphere. Today, PRL operates as a premier national research institute and functions as an autonomous unit of the Department of Space, Government of India. It maintains a close collaborative relationship with the Indian Space Research Organisation (ISRO) on various scientific and deep-space missions.
Research at PRL spans a wide spectrum of fields, including astronomy, astrophysics, planetary sciences, geosciences, space and atmospheric sciences, and theoretical physics. The institution played a foundational role in the early stages of India’s space programme, long before the formal establishment of ISRO in 1969. The selection of three of its distinguished scientists as Fellows of the Meteoritical Society serves as a testament to the world-class analytical facilities and academic excellence nurtured within its laboratories.
