Momentus to test Pulsar’s Hall Effect Thruster in space

SAN JOSE, Calif. - Momentus Inc. (NASDAQ:MNTS), a space technology company with a market capitalization of $15.59 million and impressive gross profit margins of 92.49%, has signed a contract to demonstrate Pulsar Fusion’s Hall Effect Thruster (HET) technology in orbit, according to a press release statement from the company. InvestingPro analysis suggests the stock is currently trading below its Fair Value.

The mission is scheduled for late 2026, when the propulsion system will be launched aboard Momentus’ Vigoride orbital service vehicle. The demonstration will test Pulsar’s HET system, which is designed for high-efficiency thrust for spacecraft.

"We’re thrilled to support Pulsar’s journey to develop next generation technology," said John Rood, CEO of Momentus.

The Hall Effect Thruster is engineered for high specific impulse and long-duration missions, making it suitable for satellite station-keeping, orbital transfers, and deep space exploration. During the mission, the companies plan to validate key performance metrics including thrust efficiency, thermal stability, and electromagnetic compatibility.

Momentus, a U.S. commercial space company, offers satellites, satellite components, and in-space services. The company provides support for government and commercial customers with missions ranging from communications to missile tracking and science missions.

The partnership with UK-based Pulsar Fusion represents part of Momentus’ strategy to provide testing platforms for space technologies. This demonstration mission aims to advance the development of electric propulsion systems for spacecraft.

In other recent news, Momentus Inc. announced it has entered into a sales agreement with A.G.P./Alliance Global Partners to offer and sell up to $7.35 million of its Class A common stock through an at-the-market equity program. Additionally, shareholders have approved a reverse stock split at a ratio ranging from 1-for-5 to 1-for-17.85, among other proposals at the 2025 Special Meeting of Stockholders. Momentus also secured approximately $2.7 million through a warrant inducement agreement, involving the exercise of previously issued warrants at a reduced price. In a significant development, Momentus was awarded a contract by NASA to study flying robotics technologies into space, with the potential for a follow-on mission proposal. Furthermore, Momentus will demonstrate large-scale structure assembly for DARPA in 2026, as part of the NOM4D program, having already completed the Preliminary Design Review phase.
