Venturi Space Successfully Tests “MONA-LUNA” Rover at ESA’s New Lunar Facility

Venturi Space has announced the successful completion of the first driving tests for its MONA-LUNA lunar rover. Conducted at the European Space Agency’s (ESA) newly inaugurated LUNA analog facility in Cologne, Germany, these tests mark a pivotal step in Europe’s roadmap toward autonomous lunar exploration. The rover, designed to be “100% European,” demonstrated its capability to navigate loose regolith and steep inclines, validating key technologies intended for a targeted 2030 mission to the Moon’s South Pole.

According to the company’s announcement, the tests focused on mobility, obstacle traversal, and the durability of onboard electronic systems under simulated lunar conditions. The successful campaign confirms the viability of Venturi’s proprietary wheel technology and sets the stage for further development leading up to integration with the European Argonaut lander.

Validating Mobility in a Simulated Lunar Environment

The testing campaign took place at the LUNA facility, a joint operation by ESA and the German Aerospace Center (DLR) that opened in September 2024. The facility features a 700-square-meter hall filled with 900 tonnes of regolith simulant, volcanic powder derived from the Eifel region, designed to mimic the surface of the Moon. The environment also replicates the unique lighting conditions of the lunar South Pole, providing a high-fidelity testing ground for robotic systems.

Venturi Space reports that the MONA-LUNA rover exceeded initial performance targets during these Test-Flights. Specifically, the vehicle successfully climbed slopes of up to 33 degrees and navigated large rocky obstacles without losing traction. A primary objective was to verify that the rover would not sink into the loose soil, a common hazard in lunar exploration.

Performance of Hyper-Deformable Wheels

A critical component validated during these tests was the rover’s “hyper-deformable” wheel technology. Invented by Venturi, these wheels are designed to absorb shocks and maximize the contact patch with the ground, providing necessary grip on soft, unstable surfaces. Dr. Antonio Delfino, Director of Space Affairs at Venturi Space, emphasized the importance of this validation.

“The main objective… was to validate the rover’s mobility in conditions representative of a lunar surface, with a particular focus on the interaction between its hyper-deformable wheels and a highly realistic regolith simulant.”

Technical Specifications and Mission Profile

The MONA-LUNA is engineered to serve as a logistics and exploration vehicle capable of surviving the harsh lunar environment. According to technical details released by Venturi Space, the rover weighs approximately 750 kg, with the capacity to extend to 1,000 kg depending on specific mission payloads. It is capable of speeds up to 20 km/h (approximately 12.4 mph).

The vehicle is electrically powered, utilizing solar panels and three high-performance batteries. Crucially, the rover is built to endure the extreme thermal variations of the lunar cycle, with a stated operating range of -240°C to +110°C. It is equipped with a robotic arm for scientific tasks and is designed to carry cargo or, in emergency scenarios, an astronaut.

AirPro News Analysis: The Push for European Autonomy

The development of MONA-LUNA represents a strategic shift toward European independence in space logistics. Currently, much of the global lunar infrastructure relies on non-European Partnerships. By developing a sovereign rover capable of launching on an Ariane 6 rocket and landing via the European Argonaut lander (developed by Thales Alenia Space), Europe is securing its own access to the lunar surface.

This autonomy is further supported by Venturi’s industrial expansion. The company plans to open a new 10,000-square-meter facility in Toulouse, France, by 2028. This factory will employ approximately 150 engineers dedicated to the Manufacturing of the MONA-LUNA, signaling a long-term industrial commitment beyond the initial prototype phase.

Future Roadmap: From FLIP to MONA-LUNA

While the MONA-LUNA is targeted for a 2030 launch, Venturi Space has outlined an incremental approach to technology validation. Before the full-sized rover reaches the Moon, a smaller “sister” rover named FLIP (FLEX Lunar Innovation Platform) is scheduled to launch in 2026.

Developed in partnership with the U.S. company Venturi Astrolab, FLIP will fly on a commercial mission with Astrobotic. This earlier mission will serve as a “pathfinder,” testing the same batteries and wheel technologies in the actual lunar environment four years before the MONA-LUNA mission. Gildo Pastor, President of Venturi Space, expressed confidence in the current progress following the Cologne tests.

“Seeing MONA LUNA operate on the legendary LUNA site is a profound source of pride… We know we have only completed 1% of the journey that, I hope, will take us to the Moon.”

The successful completion of these driving tests at the LUNA facility confirms that the foundational mobility technologies required for Europe’s 2030 lunar ambitions are now operational in a relevant environment.
