Introduction
As NASA accelerates its efforts to establish a permanent presence on the lunar surface, the agency is prioritizing advancements in surface mobility. To ensure that future astronauts and robotic systems can traverse the lunar landscape with greater range and efficiency, space agency officials recently hosted the Rock and Roll with NASA Challenge.
This initiative served as a high-stakes proving ground for innovative wheel technologies designed to withstand the unforgiving conditions of the Moon. By inviting public innovators to submit their concepts, NASA sought to identify robust, scalable, and lightweight solutions capable of supporting long-duration exploration. The competition culminated in a rigorous testing phase on July 31, 2026, at the agency’s specialized testing grounds in Houston.
What Happened
The competition drew significant international interest, resulting in 128 distinct submissions from 49 different countries. Following a comprehensive review process, five finalist teams were selected to demonstrate their hardware in a real-world testing environment. These trials took place at the Johnson Space Center’s Rock Yard, a facility designed to replicate the challenging topography found on the Moon.
During the event, each prototype was mounted onto the MicroChariot, a 45-kilogram test rover. The vehicles were then navigated through a series of demanding courses to evaluate how well the wheels maintained traction, absorbed impacts, and handled the complex terrain. The event featured collaboration between NASA engineers, students from the NASA Robotics Academy, and the competing teams, all working together to push the boundaries of current lunar mobility technology.
Background
The development of reliable lunar surface mobility is essential for the success of future lunar missions, including the establishment of a permanent base. Current strategies rely on ground-based prototypes to validate new technologies before they are deployed to the Moon via the Commercial Lunar Payload Services initiative.
The challenge was administered by HeroX on behalf of NASA, with oversight from the Common Robotics Project within the Robotic Systems Technology Branch at the Johnson Space Center. Furthermore, the agency’s Center of Excellence for Collaborative Innovation managed the contract, while experts from the Glenn Research Center provided technical reviews of the proposed designs.

Participating Designs and Performance
The competition highlighted five unique approaches to solving the challenges of lunar travel. Each design offered a different philosophy regarding material science and mechanical flexibility:
- Scotch Pad Tyres: Developed by Daniel and Isaac Bloomfield, this winning concept utilizes a Nomex-based structure with an aluminum hub. Its outer surface is treated with epoxy and corundum grit to maximize grip.
- HTR Variable Flex Lunar Wheel: Created by Hellenic Technology of Robotics SA, this design features an internal system capable of adjusting wheel stiffness to accommodate varying terrain.
- Hiper Wheel: Designed by Hyperbola, this model uses a corrugated structure and tensioned cables to provide spring-like movement without traditional spokes.
- Huff Helo Flexible Titanium Wheel: Engineered by Huff Helo Inc., this prototype uses formed titanium sheets. While durable, testers noted its high rigidity caused the wheel to bounce on certain obstacles.
- Payne Aviation Wheel: Conceptualized by Deborah and Craige Payne, this design incorporates pneumatic principles and historical automotive tire concepts.
Impact
The primary goal of this crowdsourcing effort was to move beyond traditional design constraints. By soliciting ideas from non-traditional industries, NASA gained access to a wider variety of technologies that could eventually be adapted for diverse mission requirements.
“Every additional kilometer a rover can reliably travel will expand how far we can explore, what science we can achieve, and what infrastructure we can build,” said Ed Herrera, a robotics engineer at Johnson and co-leader of the challenge project.
The data gathered from the Rock Yard tests confirmed that no single wheel design is a "one-size-fits-all" solution. Different mission profiles—varying by load capacity, speed, and terrain—will likely require a suite of different mobility technologies to ensure operational success on both the Moon and Mars.
What Happens Next
While the initial phase of the Rock and Roll with NASA Challenge has concluded, the project has provided a foundation for future development. NASA engineers anticipate that upcoming phases will involve exposing the most promising designs to extreme environmental stressors, such as the vacuum of space, lunar-like dust, and severe temperature fluctuations within thermal vacuum chambers.
Future testing may also focus on scaling these prototypes to support larger loads and evaluating their performance over significantly longer distances. As Lucien Junkin, a robotics engineer and co-leader of the project, noted, advancing these wheel technologies is a fundamental requirement for the future of lunar exploration.
