Momentus is a space infrastructure services company. As a first mover, Momentus will offer the most basic, foundational services that enable businesses to flourish in space. With their experienced team of aerospace, propulsion, and robotics engineers, Momentus makes and operates cost-effective and energy-efficient in-space transport and service vehicles that utilize water plasma propulsion technology. Momentus has service agreements in place with numerous private satellite companies, government agencies, and research organizations.
Momentus is a space infrastructure services company that develops and operates in-space transportation and service vehicles, enabling the movement and deployment of payloads in orbit. It specializes in foundational space logistics services that make satellite deployment, orbital transfer, and in-orbit servicing more accessible and cost-effective. Momentus leverages proprietary water plasma propulsion technology, which uses water as a propellant ionized into plasma, offering a more sustainable and energy-efficient alternative to traditional chemical propulsion. This innovation supports commercial satellite operators, government agencies, and research organizations by reducing operational costs and increasing flexibility for satellite missions[1][2][3].
Founded in 2017 by Mikhail Kokorich, a physicist and self-taught engineer with prior entrepreneurial experience, Momentus emerged to address the growing need for efficient in-space transportation. Kokorich, a two-time Y Combinator founder, led the company through its early development phase, focusing on water plasma propulsion technology. Momentus joined Y Combinator in Summer 2018, growing its team to over 125 employees based in Santa Clara, California. Early milestones include successful ground and space tests of its Microwave Electrothermal Thruster (MET) and a demonstration mission in 2022, which had mixed results but marked a significant step in operational validation[2][3].
Momentus is positioned at the forefront of the burgeoning space infrastructure and logistics trend, which is critical as satellite constellations and space-based services expand rapidly. The timing is favorable due to decreasing launch costs, increased satellite deployments, and growing demand for in-orbit servicing and repositioning. Market forces such as commercial space commercialization, government space initiatives, and technological advances in propulsion favor Momentus’s growth. By enabling more efficient satellite deployment and management, Momentus contributes to the maturation of the space economy and supports the broader ecosystem of satellite operators and space service providers[1][3].
Looking ahead, Momentus aims to refine and scale its in-space transportation services, improve mission reliability, and expand its customer base. Trends shaping its journey include the rise of mega-constellations, increased government and commercial space activity, and advances in propulsion and autonomous spacecraft operations. As the space economy grows, Momentus’s role as a foundational infrastructure provider could become increasingly pivotal, potentially expanding into on-orbit refueling and servicing. Continued technological validation and operational success will be key to enhancing its market position and investor confidence[3][1].
