Bangalore, April 1, 2026 – The Indian Space Research Organisation (ISRO) has officially announced the approval and initiation of its next Venus mission, Shukrayaan-3. Following the success of Chandrayaan-3 and the upcoming Gaganyaan mission, Shukrayaan-3 aims to further explore the mysteries of our solar system's hottest planet. The mission received final clearance from the Union Cabinet earlier this week, paving the way for development and launch preparations.

Shukrayaan-3 builds upon the foundation laid by its predecessor, Shukrayaan-1, which is still operational and sending back valuable data. However, Shukrayaan-3 represents a significant leap in technological capabilities, featuring more advanced scientific instruments and a more robust spacecraft design to withstand Venus's harsh atmospheric conditions.

Shukrayaan-3: Mission Objectives and Payload

According to ISRO officials, Shukrayaan-3's primary objectives include mapping the Venusian surface in high resolution, studying the planet's atmospheric composition and dynamics, and investigating the possibility of past or present volcanic activity. The spacecraft will carry a suite of advanced scientific instruments, including a high-resolution synthetic aperture radar (SAR), ultraviolet and infrared spectrometers, and atmospheric probes.

"This mission is crucial for understanding the evolution of terrestrial planets," stated Dr. Meena Sharma, Project Director of Shukrayaan-3, during a press conference held earlier today. "Venus, often called Earth's twin, has taken a drastically different evolutionary path. Studying it closely will provide invaluable insights into the factors that make a planet habitable or uninhabitable."

The mission's SAR will allow scientists to peer through Venus's thick cloud cover and create detailed maps of the surface, revealing geological features and potential signs of past water bodies. The spectrometers will analyze the chemical composition of the atmosphere, providing clues about the planet's climate history and potential for life. The atmospheric probes will descend into the Venusian atmosphere, measuring temperature, pressure, and wind speed at different altitudes.

India's Venus Mission: A Comparison with Other Missions

While several space agencies, including NASA and ESA, have conducted Venus missions in the past, Shukrayaan-3 represents a unique contribution due to its focus on long-term observation and in-situ atmospheric measurements. Unlike previous flyby missions, Shukrayaan-3 is designed to orbit Venus for several years, providing continuous data collection and a comprehensive understanding of the planet's dynamic environment. Reportersays, ISRO aims to leverage its expertise in developing cost-effective and reliable space technologies to achieve its ambitious scientific goals.

The mission's advanced SAR surpasses the capabilities of previous Venus radar mappers, promising to reveal previously unseen details of the planet's surface. Furthermore, the atmospheric probes will provide the most detailed measurements of Venus's lower atmosphere to date, shedding light on the processes that drive its extreme greenhouse effect.

Shukrayaan-3: India Launch Date and Expected Cost

ISRO has tentatively scheduled the launch of Shukrayaan-3 for late 2028, with a backup launch window in early 2029. "The exact launch date will depend on the alignment of Earth and Venus, which occurs approximately every 19 months," explained Dr. Sharma. The mission is estimated to cost around INR 1200 crore (approximately $145 million USD), making it one of ISRO's most ambitious and expensive interplanetary missions to date.

"The investment in Shukrayaan-3 is an investment in our future," stated ISRO Chairman, Dr. Rajesh Kumar, in a statement released this morning. "The knowledge gained from this mission will not only advance our understanding of Venus but also contribute to our ability to address climate change and ensure the long-term habitability of our own planet."
