Bolton, Ontarioโ€™s Canadensys Aerospace has received a contract with the Canadian Space Agency (CSA)ย to work on lunar agriculture. According to the announcement, they will specifically be assisting with design work on subsystems for a โ€œGround Test Demonstratorโ€ (GTD) of a Lunar Greenhouse.

The GTD is, according to the announcement, a โ€œcollaboration between the CSA and the German Aerospace Centre (DLR),โ€ and will โ€œallow Canadian and German scientists and engineers to collaborate in exploring the technologies required to build a self-sustaining bio-generative life-support system (BLSS) on the Moon.โ€ย ย 

Canadensys will be working with academic partners at the University of Guelph and McGill University to โ€œrefine the design for the Nutrient Delivery System, Illumination Control System, Plant Health Monitoring Systemโ€, and a “robotic โ€˜versatile assistantโ€™ to enable un-crewed operation of the greenhouse.โ€ย  No funding amount was mentioned in the announcement.

Ground test demonstrator of a Lunar Greenhouse

While the announcement itself did not provide more details on the Ground Test Demonstrator, and Canadensys did not respond to inquiries at time of writing, the project was described in more detail in a CSA profile of CSA Exploration Scientist Jared Stoochnoff.

Stoochnoff said that he and the CSAโ€™s Food Production Initiative were โ€œhard at work trying to develop a space-ready lunar greenhouse that we call the Ground-Test Demonstrator,โ€ which will โ€œprovide Canadian engineers and scientists a controlled environment for testing food production technologies and protocols.โ€ Stoochnoffโ€™s specific role, according to the profile, is to โ€œdefine system requirements, for example lighting, irrigation, air management, plant health monitoring, robotics, etc.โ€ as well as to โ€œassess proposals from contractorsโ€ like Canadensys.ย 

A 2023 publication in Acta Astronautica from the DLRโ€™s Volker Maiwald, Kim Kyunghwan, and Vincent Vrakking, as well as CSA scientist Conrad Zeidler, also provided more information on the GTD; as well as describing the subsystems that Canadensys will be helping to design. The paper described the GTD as a successor to the DLRโ€™s EDEN ISS project.ย  Located in Antarctica at the Neumayer III research base, EDEN ISS used a Mobile Test Facility to explore agriculture in closed-loop life support systems in hostile environments.ย  Some of the systems in the announcement, like the Nutrient Delivery System, were also part of EDEN ISS, and Canada was one of the contributors to EDEN ISS during its run from 2018 to 2022.ย 

The publication said that the Ground Test Demonstrator will actually be called the โ€œEDEN Next Generation GTDโ€ by the DLR, and that they intend it to be โ€œas close as possible to the actual lunar greenhouse in processes and design, further enhancing the analogue testing to space analogue hardware.โ€ The GTD will allow โ€œsubsystems to be tested [and] procedures developedโ€ฆ[so that] the overall system can be pareto-optimized to be as efficient as possible,โ€ they said, โ€œwhile requiring as little resources (power, water, crew time) and launch mass as possible.โ€ The GTD is intended to be โ€œa versatile science platform,โ€ they said, which will โ€œto mature technology, processes and the overall system via testsโ€ up to the point where stable operation can be demonstrated.

The CSAโ€™s LinkedIn page also pointed to a current event related to the GTD, the Concurrent Engineering Design Study. The CSA said that โ€œCanadian industry and academiaโ€ย will be joining them in a meeting with NASA, DLR and the Italian Space Agency (ASI) in Germany from March 7 to 15. The meeting will focus on efforts to โ€œmature conceptual designs for all controlled environment agriculture technologies and operations required for a space-ready lunar greenhouse.โ€ This meeting will likely include Canadensys and their designs for the systems, as well as the others detailed in the 2023 report.

Canadensysโ€™ variety of lunar activities

In any case, the announcement points out that this is only one part of Canadensysโ€™ lunar efforts, including on efforts focused on lunar agriculture. They also cited Canadensysโ€™ work on โ€œdeveloping prototype lunar greenhouse systems under CSAโ€™s Lunar Surface Exploration Initiative (LSEI)โ€, and โ€œconducting sub-system research as part of CSAโ€™s Space Technology Development Program (STDP)โ€ as examples of lunar-focused work. 

As covered in SpaceQ, Canadensys will also be designing the first Canadian lunar rover. The company also contributed to the recent Intuitive Machines lunar landing, as seen in SpaceQโ€™s recent interview with Canadensys president Christian Sullaberger on the mission and the companyโ€™s contribution.

On the Ground Test Demonstrator project, Sullaberger said in the announcement that โ€œthis activity augments our other efforts in the field of lunar food productionโ€, and that Canadensys is โ€œproud to be developing space greenhouse systems to support international Artemis astronauts during lunar surface missions.โ€ Gilles Leclerc, the Director of Government and International Affairs at Canadensys, said that the project will โ€œstrengthen space collaboration between Canada and Germany,โ€ and also โ€œpositions Canadensys as a key international provider of agriculture services on the Moon.โ€
