What are the Key Challenges in the Indian Space Programme Mission ?

• Limited Budget allocation: 
  • The Indian space program operates on a relatively modest budget compared to other major space-faring nations.
  • India's space budget is only 0.05% of its GDP. In contrast, the US allocates 0.25% of its GDP to space activities.
• Technological Challenges:
  • India stands at No. 7 globally in terms of satellites operated. It lags behind the US and China, the top two spacefaring powers.
  • India relies on the West for critical components for launch vehicles, spacecraft, and satellites.
  • India's Human Spaceflight Program poses unique challenges in terms of astronaut training, life support systems, and ensuring the safety of crew members.
    
• Commercialization and Market Access:
  • India has limited presence in space manufacturing, human space transport, space tourism, and high-altitude platforms.India’s share of the world space economy is barely 2.6%.
  • Indian investors are risk averse and prefer safe investments like 5G rather than long-term, high-risk investments in space technology
  • Start-ups in the Space sector need attention – capital, human resources, policy, support from ISRO and market
• Space Policy and Legislation:
  • Developing comprehensive space policies and legislation that address the evolving needs of the space sector is crucial.The delay in the passing of the Space Policy is becoming a big drag.
  • The Indian Space Policy,2023 sets out an ambitious role for InSPACe (Indian National Space Promotion and Authorisation Centre)  but provides no time frame for the necessary steps ahead
• Space Debris Management:
  • As the number of satellites and space activities increases, managing space debris becomes crucial. 
  • India needs effective strategies to minimize debris generation and actively participate in international efforts for space debris mitigation.
• Geopolitical Realignment :
  • India's participation in the Artemis Accords with the USA has been viewed as a counter to China in the changing geopolitical landscape.
• Competitive Edge :
  • Maintaining a competitive edge in the global space market  requires regular innovation, cost-effectiveness, and timely execution in the international space market.
• Space Applications for Societal Benefits:
  • Maximizing the societal benefits of space applications, such as remote sensing and satellite communication, requires effective integration with various sectors like agriculture, disaster management, and environmental monitoring.
  • Increasing public awareness about the benefits of space exploration and fostering interest in space science among students are essential for building a strong foundation for future advancements in the field.

What Should be the Way Forward to Realize India’s Full Potential in the Space Domain?

• Substantial Investment: A shift from "frugal engineering" to more substantial investments and ambitious projects is necessary. There has been a constant urge from the science community to enhance the budgetary allocations to the department to push for bigger missions.
• Gain Expertise in Human Spaceflight: India must invest in human spaceflight programs, astronaut training, and the development of necessary infrastructure for crewed missions
• Private Sector Participation: Involving the private sector is crucial, aligning with the global trend where commerce plays a significant role in space programs.
• Geopolitical Negotiations: With great power rivalry extending to space, India must navigate negotiations and collaborations strategically, especially considering its relationship with China.
• Legal Framework: As space activities increase, India needs comprehensive domestic and international laws to regulate and promote space business. Global governance reforms are necessary to address evolving challenges.
• Rekindling Spirit of International Collaboration: Collaboration with other countries is essential for India's space aspirations.India needs to rekindle the spirit of cooperation and ensure that outer space remains a shared domain for all of humanity
• Public Support: The government will have to engage in outreach and education to build public awareness and enthusiasm for its space program.

Conclusion:

India's space program requires strategic financial planning and active international collaborations along with public engagement initiatives  to propel India's space program to new heights.
