• Integration of a payload under a task order awarded by NASA to demonstrate on-orbit an innovative Power Processing Unit (PPU) and energy management system developed by CisLunar Industries.

Momentus plans to conduct an on-orbit demonstration of the low-cost RPO sensor suite and the CisLunar PPU and energy management system, along with several other payloads, on its Vigoride 7 Orbital Service Vehicle (OSV) that is manifested to be launched on the Transporter 16 mission with SpaceX targeted to launch no earlier than March 2026.

Momentus also received payments in January 2026 from NASA for deliverables accepted under task orders to demonstrate on-orbit the Commercial Orbital System for Microgravity In-Space Crystallization (COSMIC) technology from SpaceWorks Enterprises, Inc., and the Rotating Detonation Rocket Engine from Juno Propulsion, Inc. Momentus plans to launch these advanced payloads on a mission in 2027.

Momentus expects to receive additional payments from NASA and AFRL as it achieves additional contract milestones in 2026.
