Vigoride-5, one of Momentus's orbital transfer vehicles, using water plasma propulsion — an unusually gentle, low-toxicity thruster technology — to ferry rideshare satellites to their individual final orbits. Momentus specifically chose water as its propellant of choice because it's non-toxic and easy to handle on the ground, a deliberate departure from the hazardous hydrazine propellants that have defined satellite propulsion for decades.
