Rides on rockets powered by water

Momentus provides water-powered transportation services for spacecrafts large and small to efficiently and inexpensively extend the lifetime of their missions. Though we produce a number of physical products, we consider ourselves first and foremost a services company because we are focused on the destination. We believe it’s short-sighted to look at what we’re providing as mere hardware because we are building more than a company - we’re laying the groundwork for the in-space transportation industry.

Vigoride™
Smallest ESPA class platform powered by our Vigor™ thruster for rides from LEO with wet starting mass less than 180 kg, could be mounted radially on a 380 mm port, ESPA envelope volume. capable of delivering sizable payloads (up to 50 kg) from LEO or GTO to GEO, Lunar orbits and beyond.
  • STARTING MASS 180 KG (ESPA)
  • OR 300 KG (ESPA GRANDE)
  • UP TO 6 KM/SEC ∆V
  • 500 W SOLAR PANELS
  • SPECIFIC IMPULSE UP TO 700 SEC

Ardoride™
Powered by the mighty Ardor™ thruster, we’ve developed this ride for a smaller payload or spacecraft, with the ability to carry several hundred kg payloads to GEO and beyond. This is perfect for small deep space missions, in-space services such as orbit cleaning and satellite deorbiting, or as a booster stage for small launch vehicles.
  • 500-1250 KG WET MASS
  • 180 KG PAYLOAD TO LUNAR ORBIT FROM LEO
  • 250 KG PAYLOAD TO MARS ORBIT FROM GTO
  • UP TO 6 KM/SEC ∆V
  • 2-3 KW SOLAR PANELS
  • SPECIFIC IMPULSE UP TO 700 SEC
No better way
to get around deep space
Greater efficiency means more payload
Ardorides™ and Vigorides™ have a significantly higher specific impulse than missions powered by chemical propulsion and require less onboard propellant to achieve the required ∆V for deep space missions.
Ready to go
Our rides are a complete package, ready for launch or tailored to your mission specs. Thanks to a higher thrust per watt than ion propulsion, our rides take months, not years.
Pay less for your payload
Using denser propellant and having the ability to be piggybacked, our rides keep launch costs extraordinarily low.

More control over
your small sats.
We are a services-based company. Zeal™ and Vigor™ are the only two individual hardware components we offer. These thrusters are small but mighty in their respective abilities to power small sat missions.
  • Vigor™
    Thanks to low power consumption and compact packaging, Vigor™ is blazing a trail to bring water plasma propulsion to microspacecraft and can also be utilized as a main thruster on a future Vigoride™ and attitude control thrusters on Fervorides™ and Valorides™.
    • Water plasma
    • Power from 100W
    • Specific Impulse 350-500 sec.
    • Available 2019
  • Zeal™
    Small enough to pack inside a Cubesat “tuna can” in one block (including control and power unit), this water electrothermal resistive thruster can be the main power source for cube-, nano- and microsat missions or multiple can be used for attitude control onboard Vigorides™ and Ardorides™.
    • Water thermal resistive.
    • Power up to 30W
    • Specific Impulse 150-180 sec.
