Engineering Mars: opportunities generated by space exploration

Our fascination with Mars is never ending. And without brilliant engineering, it would still lie as a mysterious red glint in the night sky, steeped in mystery and myth. Without doubt our curiosity has motivated us to drive scientific and technological advancements for decades. From the early flybys to the landing of rovers like Perseverance, Mars exploration has continuously challenged and expanded the boundaries of engineering.

As the possibility of manned missions draws ever closer, the engineering sector stands to gain immensely.  Mars exploration will push the limits of technology, inspiring innovation, interdisciplinary collaboration, and the kind of advancements that are now only on the cusp of our imaginations. The journey to Mars is not just about discovering a new world—it is about redefining what is possible for humanity as a whole.

Pushing the limits of technology

Truth is, there are no limits to technology. As problems evolve, so do solutions. So everything is constantly new, forcing invention and ingenuity. Exploring Mars requires engineering solutions that surpass those developed for Earth-based applications. The harsh conditions of Mars, including extreme temperatures, high radiation levels, and low atmospheric pressure, necessitate the development of novel technologies.

• Advanced robotics and automation - Mars exploration relies heavily on robotic systems, such as rovers and drones, which must operate autonomously due to the significant communication delay with Earth. The development of these machines drives advancements in AI, machine learning, and automation, all of which have provided applications beyond space exploration. Clear evidence for this lies in the fact that the development of autonomous vehicles and smart manufacturing systems has devolved directly from space inventions.

• Materials science and engineering - Engineers are developing stronger, lightweight, and radiation-resistant materials for spacecraft, space habitats, and exploration tools. Innovations in materials science, such as self-healing polymers and shape-memory alloys, are finding place in industries ranging from construction to biomedical engineering

• Energy and sustainability technologies – In order to sustain humans on Mars, we need to find energy sources that are both renewable and highly efficient.Engineers are working on advanced solar panel technologies, compact nuclear reactors, and energy storage solutions. These breakthroughs not only support space missions, but also contribute to sustainable energy efforts on Earth, particularly in remote or disaster-prone regions.

Interdisciplinary collaboration

Mars exploration is not solely an engineering challenge; it necessitates collaboration across multiple scientific and technical disciplines. There is no doubt that expertise from fields such as aerospace engineering, computer science, environmental science, and biomedical engineering has led to groundbreaking innovation.

• Aerospace engineering and spacecraft design - Designing spacecraft capable of withstanding the journey to Mars requires expertise in aerodynamics, propulsion systems, and structural engineering. Engineers develop cutting-edge propulsion methods, such as ion propulsion and nuclear thermal propulsion, which have the potential to revolutionise space travel and satellite technology.

• Life support systems and environmental engineering - Sustaining human life on Mars demands innovative life support systems that recycle air, water, and waste efficiently. These advancements contribute to closed-loop environmental solutions on Earth, enhancing water purification and waste management systems in urban and industrial settings.

• Medical and biotechnological engineering - The challenges of human health in space inspire incredible innovations in telemedicine, robotic surgery, and personalised healthcare here on Earth. Engineers are developing medical devices that function in low-gravity environments, and which have benefits for remote healthcare delivery on Earth, particularly in rural and underserved communities.

Inspiring a new generation of engineers

The quest to reach and colonise Mars serves as a powerful motivator for students and professionals alike, encouraging them to pursue careers in STEM fields (Science, Technology, Engineering, and Mathematics).

• Educational and workforce development - As the demand for skilled engineers grows, educational institutions will tend to incorporate a greater amount of space exploration topics into their curricula. Universities already offer specialised courses in space systems engineering, robotics, and planetary science, equipping students with the knowledge and skills necessary to contribute to Mars missions and beyond.
• Entrepreneurship and industry growth - The Mars exploration industry has spurred a wave of private sector involvement, with companies like SpaceX, Blue Origin, and Lockheed Martin leading the charge. This has created opportunities for startups and entrepreneurs to develop innovative space technologies, from 3D-printed habitats to bio-regenerative life support systems.
