Open Space is designing its first launch vehicle, Neutrino I, to maximize cost-effectiveness and operability via incorporation of simplified liquid propulsion systems, a major emphasis on modern structural composites, and a unique approach to rocket engine cooling. Its maximum payload will be a target 50 kg, which is much lower than those of Open Space's American competitors. This enables dedication to a cost-reductive approach to space access that will support the reliable delivering of small microsatellites and nanosatellite constellations. Neutrino I's fuel tanks will be Canadian-manufactured COPV's designed to power the rocket's pressure-fed engines, while the use of an ablatively-cooled multi-composite nozzle will take the place of popular regenerative cooling techniques. The entirety of the vehicle's components are aimed for development within country while off-the-shelf hardware is of particular interest.
