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.

Top 10 Skills in UK Space Careers According to LinkedIn & Indeed Job Postings

The UK space sector is accelerating fast—expanding through satellite communications, Earth observation, launch services, and new technologies like small satellites and space robotics. As this dynamic industry grows, employers are seeking professionals who can blend engineering, data, software, and operations with strategic insight. But what skills actually get you noticed in UK space sector job ads? Drawing from LinkedIn and Indeed, this article lays out the Top 10 space industry skills in demand for 2025. You’ll also get practical guidance on showcasing these skills in your CV, interviews, and portfolio, plus a 12-week learning roadmap to build them.

The Future of Space Sector Jobs: Careers That Don’t Exist Yet

The space sector is experiencing a dramatic transformation. Once dominated by government agencies such as NASA, ESA, and the Russian Space Agency, space has become a global commercial marketplace. Start-ups, private investors, and international partnerships are fuelling a new “space race” that is not only about exploration but also about economic growth, defence, climate science, and connectivity. The global space economy was valued at over $500 billion in 2023, with forecasts predicting it could surpass $1 trillion by 2040. The UK has its own ambitious target: capturing 10% of the global market by 2030, representing an industry worth £40 billion annually and supporting more than 100,000 jobs. UK contributions to the sector already include: Satellite leadership: Surrey Satellite Technology Ltd (SSTL) pioneered small satellites. Telecommunications: Inmarsat and OneWeb are global leaders in satellite connectivity. Launch capacity: Spaceport Cornwall and proposed Scottish spaceports place the UK on the map for satellite launches. Science & exploration: British scientists have contributed to missions like Mars Rovers and the James Webb Space Telescope. But the future of space goes far beyond satellites and rockets. As space technology converges with AI, robotics, quantum computing, materials science, and biotechnology, entirely new careers are emerging. Many of the most impactful space jobs of the next 20 years don’t exist yet. This article explores: Why new space jobs are inevitable The future careers most likely to appear How today’s roles will evolve Why the UK is uniquely positioned to lead How professionals can prepare now
