The success of Chandrayaan-3, India's lunar exploration mission, can be attributed to several factors and the contributions of various entities. Here are the key points:

• Technical Expertise: One crucial factor is the technical expertise of the Indian Space Research Organisation (ISRO) which has a proven track record in space missions, including the successful Chandrayaan-2.
• Budget Allocation: Adequate budget allocation by the Indian government ensures the necessary resources and infrastructure are available for the mission.
• Collaboration: Collaboration with other space agencies and entities, both national and international, can provide valuable insights and resources.
• Research and Development: Continuous research and development efforts in spacecraft design, propulsion systems, and lunar exploration technology help improve the chances of success.
• Mission Planning: Thorough mission planning, including comprehensive risk assessments, simulations, and contingency plans, increases the likelihood of achieving mission objectives.
• System Integration and Testing: Rigorous system integration and testing processes, including simulations and ground testing, are vital for identifying and rectifying any potential issues or failures before the launch.
• Public Support: Public support and enthusiasm play a crucial role in motivating and encouraging the scientists, engineers, and researchers involved in the mission.

By considering these factors and leveraging the contributions made by various entities, Chandrayaan-3 has a higher chance of achieving its objectives and contributing to lunar exploration.
