The Best Free Tools & Platforms to Practise Space Skills in 2025/26
Space has always inspired human imagination, but today it is also a booming global industry. The UK space sector is worth billions, employing tens of thousands of people and spanning everything from satellite communications and Earth Observation to spacecraft design, propulsion, and deep-space exploration. With growth forecast for the coming decade, there has never been a better time to prepare for a career in space technology. Yet the reality of working in the space sector is that theory alone is not enough. Employers want candidates who can demonstrate applied skills — the ability to design, model, simulate, and test. They want to see you can handle data, understand system integration, and work with the same kinds of tools used in industry. The challenge is that professional software suites in aerospace and space engineering are often prohibitively expensive. But here’s the good news: there are many free and open-source tools available that allow you to practise space-related skills right now. From mission visualisation and data processing to computational fluid dynamics and systems engineering, these tools let you gain hands-on experience without spending a penny. In this article, we explore the best free tools and platforms to practise space skills in 2025. You’ll learn what each one offers, how it supports your development, and how to use it in projects that strengthen your portfolio for space sector jobs.
