Main Trends & Challenges in the Space Sector

The global space sector is undergoing a profound transformation. Commercial growth is accelerating, governments are increasing investment in security and sovereign capabilities, and technologies such as artificial intelligence are changing the space value chain. At the same time, orbital congestion and critical infrastructure vulnerabilities are creating new sustainability and resilience challenges. 

PwC’s fifth edition of Main Trends & Challenges in the Space Sector examines these developments and the opportunities they create across the global space ecosystem.

• Growth and commercial development: a trillion-dollar trajectory, record launch activity and new markets beyond Earth. 
• Security and strategic technologies: rising government expenditure, sovereign capabilities and AI-enabled applications. 
• Sustainability and resilience: orbital debris, space traffic management and critical geodetic infrastructure. 

The space economy is entering a new phase of growth 

The global space economy exceeded US$500 billion in 2025 and is projected to surpass US$1 trillion by 2035, driven by connectivity, Earth observation, positioning services and emerging in-space markets. 

Launch activity continues to break records 

Global launch activity has more than tripled over the past decade, driven primarily by mega-constellations and the commercialisation of access to space. Growing demand is supporting new launch providers and creating pressure on existing infrastructure. 

Direct-to-Device could create a US$7–14 billion market by 2033 

By enabling satellites to connect directly to everyday smartphones, Direct-to-Device services could bring satellite connectivity to millions of users worldwide. 

The space economy is expanding beyond Earth orbit 

From lunar exploration to in-space manufacturing and servicing, new commercial opportunities are emerging across the cislunar economy and beyond. 

In-space manufacturing is moving from experimentation to commercialisation 

Demand for pharmaceuticals, advanced materials and high-value products is accelerating interest in manufacturing beyond Earth, where microgravity can unlock unique production capabilities. 

Commercial space stations are set to succeed the ISS era 

As the International Space Station approaches retirement, a new generation of commercial space stations is emerging to support research, manufacturing and human spaceflight activities. 

Government investment is growing at double-digit rates 

Global government space expenditure increased at a CAGR of more than 10% between 2021 and 2025. Security, defence and strategic autonomy are among the strongest drivers of public investment. 

Security is becoming the primary driver of space investment 

As geopolitical tensions rise, defence, resilience and sovereign capabilities are increasingly shaping space strategies, funding priorities and technology development. 

Space investment is becoming increasingly concentrated on strategic technologies 

Despite a more selective funding environment, investors continue to prioritise defence, AI-enabled applications, resilient communications and space infrastructure. 

Artificial intelligence is transforming the space value chain 

AI is accelerating the shift towards autonomous operations, advanced data analytics and orbital computing, and unlocking new capabilities across the sector. 

Space sustainability is becoming a strategic imperative 

Growing orbital congestion and debris levels are increasing the urgency of space traffic management, debris mitigation and on-orbit servicing solutions. 

Orbital debris is becoming one of the greatest risks to space operations 

With more satellites being launched than ever before, congestion in key orbital regimes is increasing the urgency of debris mitigation, space traffic management and in-orbit servicing. 

Geodetic infrastructure faces a US$105 million annual funding gap 

The infrastructure underpinning satellite navigation, positioning and timing requires approximately US$165 million per year to operate effectively, while current funding stands at only US$60 million.
