Technology developed in the UK will enable safe, autonomous lunar landings for Europe’s flagship moon mission
LONDON, July 21, 2026 /PRNewswire/ — MDA Space Ltd. (TSX: MDA) (NYSE: MDA), a trusted mission partner to the rapidly expanding global space industry, today announced it has received a Pre-Authorisation to Proceed (PATP) contract from OHB System AG (OHB), a leading European space systems provider, to deliver critical lunar landing sensors for the European Space Agency’s (ESA) Argonaut spacecraft.
The contract was formalised during the Farnborough International Airshow, where representatives of OHB and MDA Space celebrated the start of the collaboration. The PATP contract allows MDA Space to immediately begin engineering activities and procure long-lead items from its UK base of operations with support from the UK Space Agency, ahead of the anticipated full contract. Under the full contract with OHB, subject to execution of a definitive agreement, MDA Space is expected to supply two flight units of its LEIA Light Detection and Ranging (LiDAR) sensor for Argonaut’s inaugural mission to the Moon.Â
The Argonaut programme, led by ESA, represents Europe’s first independent lunar landing capability. This flagship mission will transport cargo and scientific instruments to the Moon in support of a sustained lunar presence, in coordination with NASA’s Artemis programme. The Lunar Descent Element is being developed under the prime contractorship of Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), together with a core industrial team that includes OHB System AG. OHB is responsible for delivering three critical subsystems for the success of the mission: Guidance, Navigation and Control (GNC); Telemetry, Tracking and Command (TT&C) and Electrical Power Subsystem (EPS).
“This partnership with OHB underscores our expertise in autonomous landing technologies and demonstrates the strength and innovation of the UK space sector,” said Andrew Stanniland, Managing Director, MDA Space UK. “By providing LEIA, our advanced 3D sensor technology, MDA Space will contribute directly to enabling Europe’s independent access and sustained presence on the Moon for the first time.”
Developed in the UK with support from the UK Space Agency, LEIA will be a central component of the spacecraft’s Hazard Detection and Avoidance (HDA) system. The MDA Space sensor will enable Argonaut to identify and navigate surface hazards such as craters, boulders, and rough terrain during descent to the lunar surface. LEIA’s 3D scanning LiDAR generates real-time terrain maps, allowing the spacecraft to autonomously select a safe landing site. Unlike camera-based systems, LEIA provides fast and precise mapping regardless of lighting conditions, enhancing landing safety and mission assurance. The sensor’s adaptive scan pattern is able to compensate for lander motion, covering a 40-degree field of view in five seconds, with a compact, low-mass design that is designed to offer differentiation relative to comparable space LiDAR systems.
“The selection of MDA Space for the Argonaut mission is a testament to Britain’s growing leadership in lunar technology and exploration. This milestone shows the UK has the expertise to underpin Europe’s lunar ambitions – from precision landing sensors developed in Didcot to descent engines tested in Buckinghamshire,” said Liz Lloyd, UK Space Minister. “We’re proud to back MDA Space to unlock new opportunities for the future for science and ultimately our economy.”
MDA Space brings established expertise in lunar exploration and landing technologies, with reliable and standardised sensors supporting missions ranging from lunar landings and orbital debris removal to rendezvous, docking, and Earth observation. Its lunar landing sensors, including LEIA and FLARE, the Full Wave Laser Range Finder, have been chosen for multiple commercial lunar missions.
