On May 19, 2023, ISRO organized a one-day appraisal to the national academia and research institutes on the forthcoming space science missions Chandrayaan-3 and Aditya-L1, in the premises of the ISRO Headquarters, Bangalore. The meeting was attended by more than three hundred scientists, academicians and engineers representing 20 academic and research institutes of the country, apart from a set of former and serving scientists from the centres of ISRO / Department of Space, in offline and online modes.

The Chandrayaan-3 mission, equipped with scientific payloads on its lander and rover, will conduct in-situ studies of the lunar surface, at higher lunar latitude in the Southern lunar hemisphere. The mission will also carry an experimental payload on its propulsion module, to conduct spectro-polarimetric observations of the Earth from the lunar orbit. The Aditya-L1 mission, in turn, will study the photons and the solar wind ions and electrons emitted by the Sun, and the associated interplanetary magnetic field, from a halo orbit around the first Sun-Earth Lagrange point (L1).

During the opening remarks, Shri S Somanath, Chairman, ISRO / Secretary, DOS mentioned that this appraisal with the national experts is arranged to ensure that no stone is kept unturned in order to ensure the success of the missions.

The technical sessions consisted of sessions on Aditya-L1 and Chandrayaan-3 missions, where the overview of the missions, along with the technical details were deliberated at length. The meeting was attended by the directors / eminent senior scientists from institutions like NAL, ADA, NIAS, IUCAA, IIA, RRI, TIFR, JNCASR, IIG, ARIES and NGRI, and academicians from University of Hyderabad, IIT Kharagpur, IISc, IIT-Madras, IIT-Bombay, IISER-Kolkata, Ashoka University, IIT-BHU, and MAHE. The aspects of the Navigation-Guidance-Control of the lunar lander and the Aditya-L1 spacecraft were discussed at length. The technical lessons learnt from the Chandrayaan-2 lander, and the revised configuration of the Chandrayaan-3 lander were deliberated in details.

Following the technical sessions, there were detailed discussions and deliberations involving the national experts from academics and research institutes. The discussions with national academia and institutes also led to valuable technical suggestions for configuring future space missions. The experts, during the deliberations, have provided valuable suggestions and feedback on the technical aspects of Chandrayaan-3 and Aditya-L1 missions, which were noted by the ISRO project teams for cross-checks and compliance.

During the concluding session, the members from academia and institutes unanimously opined that the project teams have taken care of every aspects of both the missions in their capacity. Above suggestions by the experts are getting addressed by ISRO.
