Western University has achieved a significant milestone in Canada's burgeoning space sector by securing a contract from the Canadian Space Agency (CSA) to develop an advanced imaging instrument for the nation's upcoming lunar utility rover. This Phase 0 contract, part of a $3.8 million investment across five Canadian organizations, positions the London, Ontario-based institution at the forefront of lunar exploration technology. Led by Professor Jayshri Sabarinathan from the Department of Electrical and Computer Engineering, the project promises to deliver a compact, multispectral camera system capable of revolutionizing how we analyze the Moon's surface.

The Dual Sensor Multispectral Imager (DS-MSI) represents a leap forward in remote sensing technology. This innovative device combines high-resolution stereo imaging for rover navigation with the ability to capture data across multiple light wavelengths, enabling detailed mapping of lunar regolith, detection of water ice, and identification of critical minerals. Such capabilities are essential for understanding the Moon's geological history and supporting future in-situ resource utilization (ISRU), where lunar materials could be harvested for fuel, water, or construction.

Understanding the Canadian Lunar Utility Rover Program

The Canadian Lunar Utility Rover (LUR) is a multi-purpose robotic vehicle designed to bolster sustainable human presence on the Moon. Unlike specialized science rovers, the LUR focuses on practical utility: transporting cargo to habitats, assisting astronauts during extravehicular activities (EVAs or spacewalks), performing construction tasks, and conducting targeted scientific investigations. This aligns with Canada's contributions to NASA's Artemis program, aiming for long-term lunar bases particularly at the resource-rich south pole.

Development timelines place the LUR's launch no earlier than 2033, following phased studies. In July 2025, the CSA awarded $14.6 million to Canadensys Aerospace, MDA Space, and Mission Control for initial rover design assessments. The December 2025 instrument contracts, including Western's, mark the next step in maturing payloads over nine months of concept refinement. This iterative process—Phase 0 concepts leading to prototypes—ensures robust, mission-ready hardware.

The Dual Sensor Multispectral Imager: Technical Breakdown

At the heart of Western's contribution is the DS-MSI, a dual-camera system integrating visible-to-near-infrared (VIS-NIR) and short-wavelength infrared (SWIR) sensors. Traditional multispectral imagers require separate filter wheels for each sensor, increasing size, weight, power consumption, and points of failure—critical concerns for space missions where every gram counts.

Western's breakthrough lies in a unified filter wheel mechanism, currently under patent application. This single, compact component cycles filters for both cameras simultaneously, capturing light signatures in targeted spectral bands. Here's how it works step-by-step:

• Stereo Imaging for Navigation: Two aligned cameras produce 3D depth maps, allowing the rover to avoid obstacles and plan paths across rugged terrain.
• Multispectral Scanning: The filter wheel rotates to select wavelengths; VIS-NIR detects surface textures and basic compositions, while SWIR penetrates dust to reveal volatiles like water ice.
• Data Analysis: Onboard processing correlates spectral data with geological models, flagging resource deposits in real-time.
• Compact Design: Reduced to fit a rover mast, minimizing mass (target under traditional systems) for efficient launch and operation.

This technology builds on Sabarinathan's prior innovations, including agricultural monitoring systems, landfill methane detectors, and a miniaturized version aboard the Skylark CubeSat for bird migration tracking.

Meet the Interdisciplinary Team Driving Innovation

Success stems from Western's collaborative ecosystem. Professor Jayshri Sabarinathan, an expert in nano-photonic sensors and remote sensing instrumentation, leads with her background in photonic integrated circuits (PICs), CubeSats, and optical communications. Key team members include:

• Catherine Neish, Earth Sciences professor specializing in planetary geology.
• Kamran Siddiqui, Mechanical and Materials Engineering professor focused on thermal management.
• Eric Pilles, Research Coordinator at the Institute for Earth and Space Exploration (Western Space).
• Kim Tait, Mineralogy Curator at the Royal Ontario Museum, providing expertise on lunar analogs.

Western University's Legacy in Space Exploration

Western has long punched above its weight in space research through Western Space, an interdisciplinary hub advancing planetary science, Earth observation, and robotics. Past CSA collaborations include astronaut training at lunar analog sites, CubeSat missions like RADSAT-SK2 for radiation testing, and a 2020 vision system for rovers.

Facilities like the new Mission Control Centre, opened in 2025, simulate space operations, preparing researchers for real missions. This contract underscores Western's role in Canada's space ecosystem, alongside peers like University of Toronto and McGill in CSA-funded lunar studies.

Implications for Higher Education and STEM in Canada

This win highlights how space contracts catalyze higher education. At Western, interdisciplinary projects unite engineering, earth sciences, and physics, fostering skills in AI-driven data analysis, nanofabrication, and mission design. Statistics from the CSA show space investments yield high ROI: every $1 generates $2.50 in economic activity, much through university-led innovation.CSA Lunar Rover Overview
