European lunar rover MONA LUNA completes its first driving tests

Toulouse, 12 December 2025 — Five months after being unveiled at the Paris Air Show, the European lunar rover MONA LUNA has successfully completed a test campaign at the European Space Agency’s (ESA) LUNA centre in Cologne, Germany. A key outcome: the vehicle shows remarkable adaptability to loose soil, slopes, and obstacles.

 

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

“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.” — Daniel Neuenschwander, Director of Human and Robotic Exploration at the ESA

 

“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.” — Gildo Pastor, President of 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” — Dr Antonio Delfino, Director of Space Affairs at Venturi Space
