Momentus Space

Momentus Space is an American space infrastructure company founded in 2017, specializing in in-space transportation and orbital services. The company develops microwave electrothermal (MET) propulsion-powered orbital transfer vehicles (OTVs) that transport satellites from rideshare orbits to their precise operational destinations.

Momentus's Vigoride OTV series rides to orbit as a secondary payload and provides on-board propulsion for last-mile satellite delivery, hosted payload services, and technology demonstration. The Vigoride platform has hosted commercial payloads from NASA, DARPA, commercial operators, and international customers, providing on-orbit validation for emerging space technologies.

The company's MET propulsion system uses water as propellant heated via microwave energy, offering a non-toxic, cost-effective alternative to conventional chemical or electric propulsion for in-space transfer vehicles.

Momentus completed a SPAC merger (Nasdaq: MNTS) and has raised significant funding from both strategic and financial investors. The company is targeting the growing market for hosted payload services, orbital logistics, and scheduled delivery of satellites to precise orbital slots.
