Singapore’s Home Team Science and Technology Agency (HTX) and ST Engineering announced a five-year Memorandum of Understanding (MoU) on Tuesday, April 28, to establish a dedicated space technology programme.
Signed at the Milipol TechX Summit (MTX) 2026, the partnership will co-develop space-based capabilities designed to force multiply the Home Team’s observational and early-warning operations. The initiative focuses on leveraging orbital data to provide first responders with critical lead time during domestic safety incidents.
Deployment of the Xplorer Satellite
Central to the programme is the development of Singapore’s first dedicated public safety satellite, code-named “Xplorer.” According to details released at the summit by Coordinating Minister for National Security K. Shanmugam, the satellite is scheduled for launch in 2029. The platform will weigh approximately 100 kg and will be placed into a near-equatorial orbit to provide high-revisit coverage of the region. A physical model of the Xplorer satellite is currently on display at the MTX 2026 exhibition floor.
Sensor Payloads and Operational Applications
The Xplorer satellite will be equipped with specialized hyperspectral sensors capable of detecting and monitoring hazardous gas plumes, such as ammonia, from orbit. This capability is specifically targeted at enhancing the Singapore Civil Defence Force’s (SCDF) ability to respond to offshore industrial leaks or maritime environmental threats. By detecting toxic signatures that are difficult to track via ground sensors alone, the satellite system acts as an early-warning layer, allowing command teams to model plume dispersion and deploy mitigation assets before the gas reaches populated areas.
Strategic Collaboration and Engineering Integration
The partnership leverages ST Engineering’s existing expertise in Earth observation and geospatial services. Low Jin Phang, Chief Operating Officer for Defence & Public Security at ST Engineering, stated that the company is applying its satellite mission experience to jointly develop capabilities that directly strengthen public safety outcomes. This collaboration follows HTX’s “HTX 3.0” transformation plan, which prioritizes high-impact technological solutions including AI-driven infrastructure and autonomous systems for national resilience.
Development and Launch
Under the terms of the five-year MoU, HTX and ST Engineering will now enter the technical design phase for the Xplorer mission. The program will involve close coordination with the newly established National Space Agency of Singapore (NSAS) to ensure regulatory and orbital alignment. Following the design and integration phases, the satellite will undergo rigorous testing at HTX facilities before its targeted 2029 launch, marking a transition in Singapore’s space strategy toward applied, public-sector mission objectives.
