TODAY INFORMS TOMORROW
Our rides, like Ardoride™ and Fervoride™, will drastically reduce cost, increase safety, prolong commercial and governmental deep space missions, and provide booster stage propulsion for launch companies. The same technologies powering these rides lay the groundwork for future cislunar and interplanetary rides like Valoride™, enabling the next phase of space exploration: water prospecting and delivery throughout the solar system, solar power stations, in-space manufacturing, and space tourism.
EFFICIENTWith a considerably higher specific impulse than chemical propulsion, 3x less propellant is needed to deliver payloads to their target orbits.
FASTFaster than electrical power provided by ion propulsion due to higher thrust for the same size solar panel.
AFFORDABLEBecause water is available throughout our solar system, there isn’t the typical cost associated with other fuels that must be transported (extremely carefully) from earth to space.
ABUNDANTWater exists on the nearest celestial bodies to us, specifically, the Moon, Mars, and many near-Earth asteroids.
SAFEUnlike the fuel for ion engines and chemical propellants (liquid oxygen, hydrogen, hydrazine, xenon) which are either cryogenic or toxic and highly pressurized, water can be stored safely in low pressure tanks and poses no risk of combustion or explosion. This makes rockets using water plasma propulsion easy to launch.
VERSATILEWater is so much more than a propellant, providing radiation shielding for human space exploration and for crew consumption along the way.

Risky or not,
Despite its obvious benefits, other spacecraft bus and propulsion companies haven’t accepted the challenge of exploring newer, better albeit unchartered territory. No one has experimented with water plasma propulsion on the scale that we are. Momentus stands apart from other companies within the asteroid resources space, too, because of our laser focused business strategy: to create the first in-space transportation ecosystem.
