Momentus Inc. announced that it has secured a NASA contract to support the Space Storms Solar Sail Sentinel Demonstration Study. The contract, awarded in 2025, follows the completion of the study and the submission of the final report to NASA, confirming the company’s readiness to advance solar‑sail technology.
The study calls for a 1,652‑square‑meter (17,782‑square‑foot) solar sail mounted on Momentus’s cislunar‑capable Vigoride orbital service vehicle. The sail will monitor space‑weather events—such as solar flares and geomagnetic storms—to provide early warning data for satellite operators and to validate solar‑sail propulsion for future missions.
This award validates the Vigoride platform’s versatility and positions Momentus to pursue additional NASA contracts. The company has previously received payments for other NASA projects, and the new contract strengthens its credibility with government customers. The study also places Momentus in a competitive field that includes other firms developing solar‑sail concepts for space weather monitoring and deep‑space exploration.
Momentus’s financial profile remains a concern. The company carries high debt, limited liquidity, and a high leverage ratio, which could constrain its ability to capitalize on new opportunities. CEO John Rood said, "Momentus is proud to support this next‑gen solar sail mission study with our Vigoride Orbital Service Vehicle. Vigoride's modular design enables us to rapidly integrate complex diverse hosted mission payloads. We're pleased to again be entrusted by NASA to perform cutting‑edge work to unlock new frontiers in space‑based systems. We're excited to help usher in a new era where solar sail propulsion provides new orbital capabilities."
The NASA contract opens the possibility of a follow‑on agreement, though its value, scope, and timing remain to be determined. The partnership underscores Momentus’s strategic focus on in‑space transportation and hosted payload services, while also highlighting the company’s need to manage its financial position to sustain growth.
