DEVELOPMENT

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.

Water plasma
propulsion
POWERING ALL OF OUR RIDES—THE BEST OPTION. FAR AND AWAY.
  • EFFICIENT
    With a considerably higher specific impulse than chemical propulsion, 3x less propellant is needed to deliver payloads to their target orbits.
  • FAST
    Faster than electrical power provided by ion propulsion due to higher thrust for the same size solar panel.
  • AFFORDABLE
    Because 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.
Water is the way
Our in-situ multipurpose
miracle resource
  • ABUNDANT
    Water exists on the nearest celestial bodies to us, specifically, the Moon, Mars, and many near-Earth asteroids.
  • SAFE
    Unlike 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.
  • VERSATILE
    Water is so much more than a propellant, providing radiation shielding for human space exploration and for crew consumption along the way.

Risky or not,
it's necessary

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.
