Hey there👋

In space tech, turning an idea into something mission-ready usually takes years.

But get this, some UK projects have climbed four full Technology Readiness Levels (TRLs) in just 12 months, thanks to the General Support Technology Programme (GSTP).

That’s not a small step forward. It’s a full-on rocket jump.

📌 TL;DR:

• Average TRL improvement: +2.28 per project

• Some achieved +4 TRLs in 12 months

• Each TRL = a huge step closer to a space mission

• Without GSTP, many of these ideas wouldn’t have happened at all

• Support includes both funding and hands-on ESA technical expertise

📈 The Power of +2.28

Across 44 funded activities between 2019 and 2024, the average TRL improvement was +2.28. To put that in perspective, TRL progress isn’t like going from 1 to 2 on a to-do list, each step represents rigorous engineering, testing, and proof in environments that mimic the extreme realities of space.

And in some cases, GSTP-funded projects hit +4 TRLs in just twelve months. That’s not just fast, in the space industry, that’s warp speed.

Why does this matter? Because every TRL jump brings a technology closer to being selected for a mission and once you’re in orbit, everything changes. Funding, partnerships, credibility… it all compounds.

🚫 Why Most Tech Stalls

Here’s the truth: without funding like GSTP’s, most high-risk, high-reward space tech never makes it off the whiteboard.

SMEs, the beating heart of the UK’s space innovation scene often don’t have the margins to gamble on R&D that might take a decade to see commercial returns. Even big players hesitate to invest in tech their boards see as too risky.

That’s where GSTP steps in, de-risking early development and pairing companies with ESA’s technical officers, specialists who don’t just hand over funding and walk away. They roll up their sleeves, troubleshoot, and help teams navigate the brutal technical hurdles between concept and mission-readiness.

One SME summed it up perfectly:

🔍 The Hidden Engine Behind Innovation

When we talk about space achievements, it’s easy to focus on launches and missions, the public, visible triumphs. But behind every satellite in orbit is a quiet slog of material testing, subsystem refinement, and problem-solving that happens years before anything reaches a rocket.

That’s what TRL advancement really is: an engine hidden beneath the headlines.

And when you can advance a technology by +2.28 TRLs on average or +4 in a standout year, you’re not just keeping pace, you’re leapfrogging the global competition.

This is how the UK develops unique capabilities like electric propulsion systems for small satellites, tech that doesn’t just support national goals but positions the country as a leader in niche, high-value areas of the global space market.

🪐 Lessons Beyond Space

Here’s the thing, you don’t have to be in aerospace to take notes from this.

Think about your own projects or business goals. What’s your equivalent of moving up a TRL? What milestones could radically shift your credibility, funding potential, or market access if you reached them faster?

Three takeaways from GSTP’s approach:

1. De-risk Early, Move Faster
   Fund the riskiest but most promising ideas first, not last. This gives you more shots on goal and the freedom to explore without the weight of immediate commercial returns.

2. Pair Funding with Expertise
   Money matters, but it’s not enough. The embedded technical officer model, where experts stay close to the work, turns funding into progress at speed.

3. Measure in Jumps, Not Steps
   Progress worth chasing isn’t always linear. Look for ways to design projects so that when they work, they leap. That’s where exponential returns live.

🤝Why This Matters for the Next Decade

Space tech has a long horizon. The full commercial and economic impact of GSTP-funded innovations might not hit for another 5–10 years. But here’s the bet: by accelerating TRL growth today, the UK is seeding the missions, capabilities, and industries that will dominate the late 2030s.

This isn’t just about satellites, it’s about shaping the UK’s role in a £490 billion global market. And if history has taught us anything, those who control the tech that missions rely on… control the market.

🏛 A Call to You

Maybe you’re in the space sector. Maybe you’re not. Either way, ask yourself:

• What’s the high-risk, high-reward project I’ve been sitting on because it feels too uncertain?

• Who could be my “technical officer”, the person or group who can accelerate my development, spot the pitfalls, and guide me past them?

• If I focused on moving up my TRL equivalent, what would +2.28 look like in a year?

And most importantly, what doors would that unlock?

Because here’s the truth: in a world moving this fast, standing still isn’t just safe… it’s a slow form of failure.

Your mission might not involve satellites or deep space propulsion. But the principles that take a CubeSat from concept to launch can take your idea from “what if” to “what’s next.”

So, what’s your TRL right now? And how will you leap it?
