General Galactic, a pioneering space startup led by former SpaceX engineer Halen Mattison and Varda Space's Luke Neise, is gearing up for a groundbreaking mission called Trinity. This mission aims to test two innovative methods of propulsion using water as the sole fuel source for a satellite weighing approximately 500 kg, which is set to launch via SpaceX's Falcon 9 rocket later this year in October. This approach is particularly significant as it could potentially transform the way satellites are powered and herald a new era in space travel.

The Trinity mission focuses on demonstrating water's utility in both chemical and electric propulsion systems. In the chemical propulsion method, water will undergo electrolysis to separate into hydrogen and oxygen, after which the hydrogen will be combusted with oxygen to produce thrust. Conversely, in the electric propulsion system, water will also be broken down into its constituent gases, which may then be used in various ways to generate thrust, showcasing a novel approach to spacecraft fuel.

If successful, the mission could have substantial implications for the future of satellite operations and space exploration at large. Utilizing water—an abundant and often available resource in space—could lead to more sustainable manned and unmanned missions, lowering costs and increasing the feasibility of extended space endeavors. The industry will be closely watching the outcomes of this ambitious project, as it could influence future designs and operational strategies in satellite technology and beyond.
