Research-based · Tested with 400+ children · Live-Crew Wednesdays
Ready for the Space Expedition?
Launch a rocket. Decode a signal from Mars. Wrestle with hard problems until thinking itself becomes a skill, and technology becomes understandable.
Start self-paced (10+), or join a mentored crew (ages 10 to 14).

A new mission every month.
Two connected missions, released one per month. 25 lessons in total: Mission 1 ‘Rocket Launch’ is available from 1 July, Mission 2 ‘Digital Images’ from 1 August.
MISSION 01
From 1 JulyRocket Launch
What do you optimise first: safety, speed, or payload? Your child programs a rocket launch and learns the building blocks of code: variables, loops, and conditions.
After this mission, your child can:
Program their own rocket launch algorithm in Scratch and explain why the code works.
MISSION 02
From 1 AugustDigital Images
A signal from Mars arrives corrupted. Your child discovers how a camera turns light into bits, how those bits travel 225 million km, and how computers detect and repair errors along the way.
After this mission, your child can:
Explain how a digital image survives noise and distance, and why the rover doesn't ship film home.
Three real challenges
Thinkable turns space into a training ground for reasoning, systems thinking, and confident decision-making. It builds scientific literacy and sparks curiosity, teaching children to think like a scientist and explore beyond the facts, into the unknown.
Code a Rocket Launch
Learn how to break down a complex problem, test their code, and iterate until it works. Build a working rocket launch algorithm in Scratch, using real programming logic: variables, loops, and conditions.
Decode a Mars Image
From the rover's camera to a screen on Earth: discover how digital images are built, encoded, and transmitted across space and what happens when something goes wrong on the way.
Fix a Transmission Error
Computers make mistakes and fix them automatically. Learn how the computer detects and corrects errors in a real Mars image (the same idea that still keeps Voyager readable billions of kilometres from home), and what happens when the error is too big to fix.
One mission a month, one hour a week.
The Space Expedition runs on two tracks. The live Crew meets weekly with a mentor; as a self-paced Explorer your child does the same missions any time. Here's the rhythm.
A new theme every month
Crew & ExplorerEach month unlocks a new interactive mission, designed for about an hour a week. The Space Expedition runs across two: program a rocket launch, then decode a signal from Mars.
Join the live session
Crew onlyOn the four Wednesdays per month from 4:30 to 5:30 PM CET, your child meets a small crew and an experienced mentor online. Small groups mean real attention and room to ask anything, and a mentor is there the moment they get stuck.
Team up between sessions
Crew onlyBetween the live meetings the crew works towards a shared milestone: presenting ideas, comparing approaches, and puzzling things out together, so no one is ever stuck alone.
Build, test and improve
Crew & ExplorerYour child writes code, runs it, and watches it fail before it works, then improves it until it does. Mistakes happen in the open, which is exactly where the learning is, and in the Crew a mentor and crewmates help puzzle them out.
Curiosity as compass
Crew & ExplorerNo grades, no pressure, every child at their own pace. The thinking gets sharper week by week, demanding but never overwhelming, with a mentor right there when it gets hard. Prefer to go solo? Every mission is also self-paced for Explorers.
Thinking that reaches the dinner table
Crew & ExplorerThrough every expedition, parents get the context, discussion topics, and small thinking challenges, so the mission carries on at home as a shared activity, around the dinner table.
Technology is the vehicle. Thinking is the goal.
Space is the perfect training ground for thinking. In space, every decision matters.
Strategic thinking
How to approach this? Children learn to choose a strategy instead of guessing. They practice reasoning under uncertainty.
Thinking about thinking
What worked? What did not? What should I try next? Active decisions, challenges, and reflection. They begin to notice and improve.
Understanding systems
Recognising how technology, data, and rules interact and what happens when something goes wrong.
Confidence with complexity
Big ideas stop feeling scary when children learn how to break them down and real confidence appears.
More effective, more fun, more confidence.
“My son on the fourth and unfortunately final day of your course: 'Today was seriously the coolest!' Thanks and Congratulations! You are doing something really great here!”
“The best course of all in STEM!!”
— Nick, 7th Grade
“I really enjoyed it! I always found computer science very challenging, but now I see how it connects with other natural sciences and is incredibly diverse.”
— Elisa, 10th Grade
“This is exactly what I imagine teaching material should look like. I can use it in my lessons without a lot of preparation overhead, it's self-explanatory, and the students have fun.”
— Julian, STEM teacher, high school
Start your expedition
Launch offer: introductory pricing for a limited time.
Two ways in. Explorer is self-paced for ages 10 and up, from €9.99 a month. Expedition Crew adds weekly live mentoring in a small group for ages 10 to 14, real teaching rather than more videos, for €79 a month.

Questions from Parents
What age is the Space Expedition suitable for?
There are two ways to explore the Space Expedition. The self-paced expeditions are open to everyone aged 10 and up, and parents are welcome to work through the challenges alongside their kids. The live mentored Crew is designed for ages 10 to 14. The content is crafted so that both beginners and more advanced explorers are challenged.
Does my child need prior experience?
No, no prior experience needed at all. We start from scratch and guide step by step through the topics.
What technology does my child need?
A computer or laptop with internet access and a modern browser. Scratch runs directly in the browser, no installation needed.
How does a session work?
Children meet Wednesdays from 4:30 to 5:30 PM CET online in a small group with a mentor. Between sessions there are interactive exercises for self-paced learning.
What will my child be able to do after the Space Expedition?
After the Space Expedition, your child will have built a working rocket algorithm in Scratch, understand how digital images are created and transmitted, and know how computers detect and correct errors in data, connecting programming, physics, and computer science in one expedition.
Is this more like school or more like an adventure?
More like an adventure with real intellectual stakes. There are no grades, no performance pressure, and no rote memorisation. Children are guided through challenges that demand real thinking and they usually leave sessions energised, not drained.
Can I cancel anytime?
Yes. The Explorer plans are month-to-month and cancel anytime. The Expedition Crew is a one-time purchase covering one full month, meaning a single mission with a mentor: no subscription, no contracts, no cancellation fees.
What if my child misses a live session?
No problem. Every mission works at your child's own pace between sessions, and the interactive lessons stay available. A missed Wednesday never means falling behind.
Who are the mentors?
Sessions are led by experienced mentors from our team: educators and computer scientists trained on the Thinkable curriculum, working with small groups so every child is seen.
How is my child's data handled?
We are based in Germany and fully GDPR-compliant. We collect only what's needed to run the lessons, never sell data, and there are no ads or in-app purchases aimed at your child.
