The first outing of the European lunar rover MONA LUNA reflects the collective work of Venturi Space’s three sites. Monaco, Switzerland and France worked hand‑in‑hand to design, develop, assemble and test the rover.
Weighing 750 kg (extendable to 1,000 kg), MONA LUNA will serve two primary objectives: to explore the lunar surface and to test critical technologies for sustainable lunar mobility. Thanks to its four wheel‑drive and four‑wheel steering system, along with passive‑damping suspension, MONA LUNA climbed and descended slopes of up to 33 degrees, exceeding initial expectations. The first results confirm the rover’s potential: The contact area of the hyper‑deformable wheels is exceptional, both on loose soil and rolling terrain.
This confirms the findings of intensive tests carried out at NASA between 2022 and 2025,Traction exceeds forecasts, Large rocky obstacles are crossed effortlessly, Dynamic stability on slopes meets programme requirements, The onboard electronic systems demonstrated excellent operational performance. Designed to support the ambitions of the European Space Agency (ESA) and France’s Centre National d’Études Spatiales (CNES), MONA LUNA already incorporates technologies that will operate on the Moon next summer — but on board another rover: FLIP. This vehicle will be equipped with the same hyper‑deformable wheels, batteries, heating systems and temperature sensors as the European rover. FLIP is developed by the North American company Venturi Astrolab, Venturi Space’s strategic partner. FLIP will also benefit from another innovative technology developed by Venturi Space: the mechanical system enabling the rover to exit the lunar lander.
Another shared feature between MONA LUNA and FLIP is their bodywork, designed by Sacha Lakic.In parallel with the MONA LUNA development programme, Venturi Space continues to expand its industrial ecosystem and will lay the first stone of its flagship facility next spring: a site of more than 10,000 m² in Toulouse, just steps away from the Centre National d’Études Spatiales (CNES). It is here that, in the first half of 2028, 150 engineers will work on the design and manufacturing of MONA LUNA, in close collaboration with the Swiss and Monegasque entities responsible for the hyper‑deformable wheels, heating systems, cryogenic materials, the rover‑lander egress system, and the high‑performance batteries.
Quotes Daniel Neuenschwander, Director of Human and Robotic Exploration at the ESA: “I was truly impressed by the way MONA LUNA handled LUNA’s challenging terrain. Watching its wheels deform and adapt to the regolith, slopes and rocks… it is remarkable. If MONA LUNA were to be selected for one of our missions, it would be a tremendous opportunity for Europe.”
Gildo Pastor, President of Venturi Space: “Seeing MONA LUNA operate on the legendary LUNA site is a profound source of pride. This rover demonstrates the performance of our wheels, our suspension systems, our electronics… and therefore the quality of the work achieved by all our teams in Toulouse, Monaco and Switzerland. We know we have only completed 1% of the journey that, I hope, will take us to the Moon.”
Dr. Antonio Delfino, Director of Space Affairs at Venturi Space: “These driving tests were primarily dedicated to locomotion. We wanted to understand how MONA LUNA behaves on loose soil, on slopes and when facing significant obstacles. The results exceed our expectations. The ability of these wheels to ‘float’ on the surface is essential to avoid becoming bogged down in lunar regolith.”
Earlier this week, Venturi Group presented its latest invention at the international Paris Air Show in Le Bourget, France: a hyper-deformable lunar wheel. Venturi Lab designed and manufactured the wheel using materials it created. The Venturi wheel is a world first.
A turning point in the history of the space industry, Venturi has reinvented the wheel. Engineers, chemists and physicists at Venturi Lab in Fribourg, Switzerland have created a unique hyper-deformable lunar wheel.
The wheel will be used on Venturi Astrolab’s FLEX rover, a vehicle that will be deposited on the Moon in 2026 by Space X’s Starship rocket and initially used to transport and deploy payloads.
In the past, with the exception of the Apollo missions, space exploration vehicles have always been equipped with rigid wheels. The Venturi wheel, however, is highly deformable while remaining long-lasting and robust. From 2026, when the FLEX rover is put into service at the lunar south pole, where extreme temperatures (-90 to -230°C) prevail, the four wheels supporting the two-tonne vehicle (payload included) will warp in order to absorb ground irregularities as the FLEX travels at 20 km/h. The wheels will need to perform over at least 1,000 kilometres and resist strong radiation from the south pole.
Features of the Venturi wheel include: – an exceptional diameter of 930 mm – a complex system of 192 cables that act as spokes – a tread made flexible by a newly invented material – an outer rim equipped with springs
This breakthrough technology, based on unique materials, is equal in importance to the arrival of the rubber, and later pneumatic rimmed tyre in the 19th century.
NASA has selected Venturi Astrolab to test and analyse the Venturi wheel at the NASA Glenn Research Center in Cleveland and the NASA Johnson Space Center in Houston.
ABOUT VENTURI Since 2000, the Venturi Group has specialised in the design and manufacture of high-performance electric vehicles. Whether through world records, expeditions on hostile terrain, the creation of the first electric sports car, the development of innovative vehicles or its involvement in the Formula E World Championship, the Venturi Group embodies and demonstrates all the capabilities of the electric vehicle on 2 or 4 wheels. Since 2021, Venturi Lab is part of the Venturi Group. The company invents, studies, designs and manufactures mobility solutions capable of handling the extreme environmental conditions found on the Moon and Mars. In 2026, Venturi Astrolab’s FLEX rover – for which the Venturi Group will have designed and manufactured innovative technologies resulting from disruptive innovations – will be in operation on the Moon.
