Chandrayaan-4 mission will ensure the safe handling and storage of lunar sample to prevent contamination by transferring the leak proof sample canisters to sample curation facility with contamination control features. Establishment of Curation Facility (Class 100 & 1000 clean room environment as per ISO standard) is planned with advanced instrument to preserve the integrity of the sample for scientific analysis. As per COSPAR (Committee on Space Research) Planetary Protection policy, lunar missions fall under the category where it does not demand stringent requirement for biological contamination.

Chandrayaan-4 mission will employ the specific Technological advancements, which include precise rendezvous and docking systems, navigation and attitude control for orbit management, robotic drill and scoop for sample collection and sealing, robotic arm for sample transfer, autonomous ascent systems, heat shield technology for re-entry module, deceleration systems to overcome the challenges of lunar sample return. Department has institutional mechanisms in place for conducting simulations, ground tests and reviews to ensure successful execution of mission.

This information was given by Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science and Technology, Earth Sciences, MoS PMO, MoS Personnel, Public Grievances & Pensions, Department of Atomic Energy and Department of Space, in a written reply in the Rajya Sabha today.
