The space industry runs on software—just not the kind you’d expect from a sector pioneering the future of humanity. Behind the sleek rocket launches and futuristic mission control rooms lies a harsh reality: much of the software running today’s space missions is outdated, clunky, and, in some cases, decades old. While hardware innovation has pushed the boundaries of what’s possible in space, software has been left in the dust. It’s time for the industry to change that.
Legacy Code in a New Space Age
NASA’s Voyager spacecraft, still transmitting data from interstellar space, runs on assembly code written in the 1970s. The Mars rovers, some of the most advanced machines ever built, operate on processors less powerful than a modern smartphone. Even in commercial space, companies rely on Fortran, Ada, and outdated versions of C++—languages that have served well but lack the flexibility and efficiency of modern alternatives.
Why? Because legacy software works. It’s been tested, validated, and, most importantly, trusted. In an industry where failures cost billions and lives are on the line, risk aversion is the norm. But as commercial space ventures accelerate and the demand for autonomy, AI, and real-time analytics grows, clinging to outdated software is no longer an option.
The Cost of Stagnation
Relying on outdated software isn’t just inconvenient—it’s actively holding the industry back.
Slow Development Cycles: Aerospace software takes years to develop, and outdated tools make it worse. Engineers spend more time fixing compatibility issues and maintaining legacy systems than innovating.
Security Risks: Old software is a hacker’s dream. Many legacy systems lack modern cybersecurity measures, leaving critical space infrastructure vulnerable to attacks.
Lack of Talent: The next generation of software engineers doesn’t want to work with codebases older than their parents. Sticking to outdated languages makes it harder to attract and retain top talent.
Limited AI & Automation: Advanced software is the key to space-based AI, autonomous spacecraft, and in-orbit servicing. Without cutting-edge frameworks, these capabilities remain theoretical rather than operational.
What Cutting-Edge Software Looks Like
Other industries have embraced modern software methodologies, and space must do the same. The solution isn’t just swapping old code for new but rethinking how software is developed, tested, and deployed.
Cloud Computing & Edge Processing: Space systems need real-time data processing, and relying on Earth-based infrastructure is inefficient. Cloud-based software, edge computing, and distributed processing frameworks can optimize in-space operations.
AI-Driven Autonomy: Machine learning and AI-driven software will power autonomous spacecraft, predictive maintenance, and adaptive mission planning—if the industry embraces the right tools.
Agile Development & DevOps: Traditional aerospace software is developed in rigid cycles that can take years. Agile methodologies, continuous integration, and DevOps practices can accelerate development without sacrificing reliability.
Rust, Python & Modern C++: While safety-critical systems require robust, well-tested languages, modern tools like Rust (for memory safety), Python (for AI and rapid prototyping), and updated C++ standards offer significant advantages.
A Call for Change
SpaceX disrupted the launch industry by rethinking rocket design, reusability, and production. Now, the next disruption must happen in software. Legacy aerospace giants, startups, and government agencies must prioritize modern software development as much as they do new propulsion systems or satellite architectures.
The future of space isn’t just about hardware—it’s about the code running behind the scenes. It’s time for the space industry to stop treating software as an afterthought and start embracing the cutting-edge tools that will drive the next generation of exploration.
Because in space, the future belongs to those who innovate. And that future is written in code.
