SPACENEWS – Water propulsion technologies picking up steam

When the Aerospace Corp. launched the Optical Communications and Sensor Demonstration in 2017, one mission objective was to test water-fueled thrusters. At the time, the idea was fairly novel. Two years later, water-based propulsion is moving rapidly into the mainstream.

Turning H20 into Delta-V: NASA to Fly Tethers Unlimited’s HYDROS-C Thruster on First PTD CubeSat.

Tethers Unlimited, Inc. (TUI) announced that NASA has selected its HYDROS-C thruster for demonstration on the first Pathfinder Technology Demonstration (PTD) CubeSat mission, planned for launch in early 2019. The HYDROS-C thruster, developed under a NASA Small Business Innovation Research (SBIR) contract and matured to flight-readiness under a NASA Tipping Point Technologies Public-Private Partnership, is a revolutionary space propulsion technology that uses water as propellant.
