08:39 AM EDT, 06/04/2025 (MT Newswires) -- Redwire ( RDW ) said Wednesday it received NASA's approval to move forward with Mason, its in-space construction tool suite for lunar and Martian infrastructure.

The system, which includes grading, compacting, and microwave sintering tools, passed its Critical Design Review under a $12.9 million Tipping Point contract, the company said.

Redwire ( RDW ) said Mason is designed to turn lunar or Martian regolith into concrete-like material to build roads, landing pads, and berms for future surface operations.

The company said the tech helps reduce health risks and hardware damage caused by regolith while also lowering launch and construction costs.

Redwire ( RDW ) added it plans to build and test the prototype and is exploring options for a demonstration flight.

Shares of Redwire ( RDW ) were up over 8% in recent Wednesday premarket activity.
