For most people, a meteorite is a curiosity — a blackened stone from space displayed behind museum glass. For Kuljeet Kaur Marhas, it is something far more profound: a time capsule carrying clues to the birth of the Solar System itself.
This year, Marhas became the first Indian woman to be elected a Fellow of the Meteoritical Society, one of the world’s most respected bodies devoted to planetary science and meteorite research. The honour places her among a small global community of scientists whose work has significantly advanced understanding of planets, asteroids and cosmic matter.
For Indian science, the recognition carries wider significance. Planetary science remains a relatively small and underfunded field in India compared with engineering, medicine or information technology. Women scientists working in highly specialised laboratory-based cosmochemistry also remain underrepresented globally. Marhas’s election therefore marks not merely a personal milestone but also a quiet institutional breakthrough.
Currently a professor at the Physical Research Laboratory — often described as the cradle of India’s space sciences — Marhas has spent years studying primitive meteorites, interplanetary dust particles and microscopic presolar grains older than the Sun itself. Her research sits at the intersection of chemistry, geology and astronomy, asking some of humanity’s oldest questions: How did the Solar System form? What materials existed before planets emerged? How did water and organic compounds travel across space?
Unlike astronomers who study distant galaxies through telescopes, Marhas’s work often unfolds under microscopes and inside ultra-sensitive laboratories. Meteorites are sliced into impossibly thin sections. Dust particles smaller than grains of sand are examined for isotopic signatures revealing origins in ancient stars that predate the Solar System. The scale may be microscopic, but the implications are cosmic.
Colleagues have frequently described her work as pioneering in the study of presolar materials and early Solar System processes. Over the years, she has collaborated internationally with institutions involved in NASA and other planetary missions, contributing to research linking laboratory cosmochemistry with broader models of planetary evolution.
Her career also reflects the gradual maturation of India’s own planetary science ecosystem. Public discussion of India’s space ambitions usually centres on rockets, Moon landings or missions such as ISRO’s Chandrayaan programme. Yet planetary science requires another layer of expertise: the ability to analyse extraterrestrial material and reconstruct the chemistry of the early Solar System. Scientists such as Marhas help build that intellectual foundation.
The timing of her election is notable. Planetary science is entering an especially exciting phase globally. NASA’s OSIRIS-REx mission recently returned asteroid samples to Earth, while renewed lunar and Mars missions are generating fresh interest in planetary origins and extraterrestrial chemistry. India, too, is expanding its ambitions beyond satellite launches towards deeper scientific exploration. Researchers such as Marhas are therefore becoming increasingly important to the country’s long-term scientific aspirations.
Yet hers is also a story of persistence within a demanding scientific culture. Cosmochemistry is painstaking work. Research projects often take years, with conclusions depending on minute measurements requiring extraordinary precision. Recognition, when it comes, arrives slowly. In such fields, reputations are built not through spectacle but through decades of careful, cumulative work.
There is also something quietly poetic about Marhas’s research. Meteorites collapse time. The rocks she studies are older than Earth itself, formed billions of years before human civilisation, before continents, before life. Through them, scientists attempt to reconstruct the processes that eventually made planets — and people — possible.
In an era dominated by flashy narratives around space exploration, Marhas represents a different scientific tradition: patient, analytical and deeply curious about origins. Her work reminds us that space science is not only about reaching other worlds but also about understanding how our own world came to exist.
For young Indian scientists — especially women considering careers in physics, astronomy or planetary sciences — her achievement may prove particularly meaningful. Visibility matters in science. So does precedent. Every first expands the horizon slightly for those who follow.
And in Kuljeet Kaur Marhas’s case, the journey from microscopic dust grains to one of planetary science’s highest honours tells a larger story about Indian science itself: slowly, steadily and often without much noise, it is beginning to claim a place in humanity’s effort to understand the universe.
