In 1960, sending 1 kg to space cost $87,000.

Today? Just $3,800.

That's a 95% price crash in 65 years — and a new Cambridge study just mapped out exactly how it happened.

Stay with me, because the ending is wilder than the headline.

The team built the world's biggest rocket database ever — over 4,400 launches since Sputnik in 1957, across 16 space-faring nations.

And what they found breaks the usual narrative.


🚀 Rockets are learning faster than solar panels

Everyone assumes solar power is the ultimate cost-crash story.

Turns out, rocket tech has an even steeper learning curve.

  • ☀️ Solar PV costs fell 99% since the 1970s — but only because millions of panels got built
  • 🚀 Rockets fell 95% with far fewer units produced

Less volume. Bigger drop. That's not normal.

It's called Wright's Law: the more you build something, the cheaper and better it gets. Space just proved it harder than anyone else.


🧊 The Cold War was actually bad for efficiency

Here's the twist nobody expected.

From the 1960s to the mid-90s, cost cuts barely came from better engineering.

Countries were just building dozens of experimental rockets and cherry-picking the cheap ones.

Efficiency wasn't the goal. National pride was.

Only after 1995 — when private companies entered the game — did the real technical learning kick in.

Learning rate jumped to 8% per generation.

⚡ Translation: competition beat Cold War muscle-flexing.


💸 Where this is headed

The researchers ran the numbers forward:

  • 📉 $1,600 per kg by 2030
  • 📉 $300 per kg by 2040

That's a 96% drop from today's price in under 15 years.

And here's the kicker — they calculated SpaceX alone could get there with just 80 flights of Starship, the reusable super-heavy rocket now mid-testing in 2026.


⚠️ But there's a catch

The whole forecast leans on one company.

SpaceX isn't just winning the space race — it's become the space race's baseline assumption.

The study's own warning:

"The world has become so reliant on a single company for cheap space access... this makes projecting the space economy particularly challenging."

One company's rocket schedule is now a variable in global economic forecasting.

Think about that.


Cheaper space isn't a sci-fi dream anymore.

It's a spreadsheet — with one company's name in every formula.

That's all for now!
