Momentus Space was founded by space entrepreneur Mikhail KokorichMikhail Kokorich and his partner Lev Khasis in Santa Clara in 2017. Momentus was originally born out of discussions with satellite operators seeking more affordable space transportation. Momentus is developing in-space propulsion systems powered by microwave electro-thermal (MET) water plasma engines. Momentus Space is the first in-space transportation services company built around high performance water plasma rocket propulsion. Momentus’ water plasma propulsions systems use water which is cheap, non-toxic, and considered safe, and easy to work with. Water based propulsion could provide a path to breaking the ties of space industries to the Earth by allowing resupply from asteroids.
