“Mobility is the ultimate enabler of science on Mars,” goes the oft-uttered mantra in planetary engineering circles. Now the phrase forms the very foundation of NASA’s newest initiative. A soon-to-be-released Science Mission Directorate program, called Science Transport & Robotic Innovation for Deployment and Exploration (STRIDE), will challenge U.S. industry to develop and prototype highly advanced robotic mobility systems to transport and deploy science payloads across the unforgiving surface of Mars.
STRIDE targets systems, both surface and aerial, which are scalable, adaptable, and relevant to operation in realistic Martian environments. This class includes the development of platforms capable of traversing steep slopes and rockstrewn plains with loose regolith in support of sensitive instruments to high-value science sites. Its open invitation is extended beyond traditional space hardware developers to terrestrial robotics firms ready to transition their technologies into extraterrestrial applications-a move that would hasten innovation by leveraging proven terrestrial mobility solutions.
The engineering demands are formidable. Mars’ topography presents navigation challenges similar to those encountered to date by the Perseverance rover, which has leaned heavily on enhanced autonomous navigation systems to achieve sustained high-speed traverses. Technologies such as FASTNAV Far Obstacle Detector have demonstrated capabilities to extend hazard detection to 20 meters, enabling traverse speeds up to 0.7 m/s-seven times faster than conventional rover operations-while maintaining safety margins. Integrating such AI-enabled perception into the STRIDE platforms could dramatically enhance daily coverage, allowing the payloads to reach a wide variety of geological targets in fewer sols.
Aerial mobility is another frontier. The thin Martian atmosphere, with just 1% of Earth’s sea-level density, imposes strict constraints on rotorcraft design. NASA’s Ingenuity helicopter proved that lightweight structures, high-rotation blades, and autonomous flight control can succeed, but its navigation systems struggled over low-contrast terrain. Recent Death Valley and Mojave Desert tests of Extended Robust Aerial Autonomy software have refined algorithms to maintain positional accuracy over sand dunes and featureless surfaces, a capability essential for aerial scouts in STRIDE missions. Such drones could reconnoiter ahead of ground units, finding safe routes and optimal payload deployment sites.
In fact, payload handling in and of itself requires special engineering. It has been determined through the studies regarding Mars Sample Return that robotic arms with seven degrees of freedom, featuring reach extension and interchangeable end-effectors, are capable of retrieving scientific samples and stowing them under the most stringent protocols for planetary protection. For STRIDE, similar manipulators could deploy seismometers, spectrometers, or atmospheric sensors, even on hazardous or uneven terrain. Designs must consider dust contamination, thermal extremes, and mechanical resilience over extended missions.
Adaptability is but one of a series of focus areas for the program, standing in concert with concepts explored in the realms of multimodal Martian transportation research, wherein rovers, drones, and even maglev systems are integrated into one cohesive logistics network. Maglev trains might represent efficient surface transport in a theoretical sense, but the associated infrastructure demands are enormous. STRIDE’s nearer-term solutions will most likely fall to modular robotic platforms that can be reconfigured for various payload and mission profiles, providing minimum fixed installations.
Energy efficiency is another important metric. Every watt counts on Mars, and mobility systems are challenged with balancing power-hungry operations against their generation capacity. Advances in lightweight AI processors have enabled, for the first time, real-time perception at sub-10 ms inference times with less than 2 W consumption using radiation-hardened VPUs and FPGAs. Deploying such hardware on STRIDE units could sustain autonomy without overtaxing power budgets during extended traverses or sorties.
This intent is borne out quite clearly in the latest excitement at NASA over the recent engagement with commercial partners for Mars payload delivery and communications relay services. Opening STRIDE to terrestrial robotics innovators allows NASA to identify capability gaps-terrain classification accuracy, multi-agent coordination, or aerial hazard avoidance-and close them with targeted development. That will be the bottom line on success: systems that do not just survive in the harsh environment on Mars but actively expand the scope and efficiency of scientific exploration. The STRIDE-idea encapsulates for aerospace engineers and robotics professionals both a great technical challenge and a market opportunity: design mobility systems that integrate advanced autonomy, robust mechanical design, and mission-specific adaptability into deployable assets for the next generation of Mars exploration.
