Introduction
Ritu Karidhal is one of India’s most accomplished aerospace engineers and an inspiration to aspiring scientists. Popularly known as the “Rocket Woman of India,” she has played a key role in several landmark missions of the Indian Space Research Organisation (ISRO). As a senior scientist and aerospace engineer, she contributed significantly to the success of India’s Mars Orbiter Mission (Mangalyaan) and Chandrayaan-2. Although her primary expertise is aerospace engineering, her work has also supported biological and environmental research by enabling satellite-based Earth observation, climate monitoring, and planetary exploration.
Early Life and Education
Ritu Karidhal was born in Lucknow, Uttar Pradesh, India, in 1975. From an early age, she displayed a deep fascination with the night sky, planets, and space exploration. She frequently read books on astronomy and collected newspaper articles related to scientific discoveries.
She completed her schooling in Lucknow before earning a Bachelor of Science (B.Sc.) in Physics from the University of Lucknow. Motivated by her passion for space technology, she pursued a Master’s degree in Aerospace Engineering from the Indian Institute of Science (IISc), Bengaluru, one of India’s premier engineering institutions.
Her academic excellence and dedication earned her an opportunity to join ISRO in 1997, where she began her distinguished scientific career.
Scientific Career & Research
At ISRO, Ritu Karidhal quickly established herself as a talented mission planner and systems engineer. She worked on several satellite and launch vehicle projects before taking leadership roles in India’s interplanetary missions.
Mars Orbiter Mission (Mangalyaan)
Ritu Karidhal served as the Deputy Operations Director for the Mars Orbiter Mission (MOM), launched in 2013. She was responsible for developing the spacecraft’s autonomous navigation and mission planning systems.
The mission achieved worldwide recognition because India became the first nation to successfully reach Mars orbit on its maiden attempt, and the mission was completed at a remarkably low cost.
Chandrayaan-2
She later became the Mission Director for Chandrayaan-2, India’s ambitious lunar exploration mission launched in 2019. She coordinated multiple engineering teams responsible for mission planning, spacecraft operations, and flight execution.
Although the Vikram lander experienced communication loss during its landing attempt, the Chandrayaan-2 orbiter continues to provide valuable scientific data about the Moon.
