Chandrayaan-3 set for August 2023 launch: ISRO chairman
The Hindu
“C-3 is ready now. It is not a replica of C-2. The rover is there. The engineering is significantly different.”
The Chandrayaan-3 mission is expected to be launched in August 2023, S. Somnath, Chairman, Indian Space Research Organisation (ISRO), said here on the sidelines of a conference.
Dr. Somnath explained that while mission parameters would remain the same there were several changes being made to the design. “The design and engineering are significantly different [compared to Chandrayaan-2] to make it more robust and avoid the problems from last time.”
The Chandrayaan-3 mission is a follow-up of Chandrayaan-2 of July 2019, which aimed to land a rover on the lunar South Pole. It was sent aboard the country’s most powerful geosynchronous launch vehicle, the GSLV-Mk 3. However, lander Vikram, instead of a controlled landing, ended up crash-landing on September 7, 2019, and prevented rover Pragyaan from successfully travelling on the surface of the moon. Had the mission been successful, it would have been the first time a country landed its rover on the moon in its maiden attempt.
The legs that would hold the body of the craft on landing were made more rugged, there are improved sensors and algorithms to identify sites where the lander could successfully descend safely and better instrumentation that would provide more resilient back-up systems, said Dr. Somnath.
On Sunday, October 23, ISRO is expected to launch 36 satellites aboard its heaviest rocket LVM3 — earlier known as the GSLV Mk3. These satellites belong to British start-up OneWeb and will launch from the spaceport in Andhra Pradesh’s Sriharikota. Telecom major Airtel has a significant stake in OneWeb. A successful mission will greatly improve ISRO’s prospects in the commercial space launch sector where it can use its heaviest rockets to launch heavy payloads.
“There is also a second set of satellites [of OneWeb] that will be launched in February next year,” he added.

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025. Their artwork takes centre stage at the Where We Gather exhibit, which is part of Festivals of Goa, an ongoing exhibition hosted by the Museum of Goa. The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
