HR001121S0018 Amendment 2 Summary of Changes.docx

This document summarizes Amendment 2 to the Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design (NOM4D) Broad Agency Announcement (BAA) from the Defense Advanced Research Projects Agency (DARPA). The amendment updates the table of contents, posting date, and section numbering in the BAA.

The NOM4D BAA solicits research proposals to develop new materials, manufacturing technologies, and design approaches that enable structures to be built on orbit and the lunar surface without constraints of launch. Specific areas of interest include high-performance feedstock materials, efficient off-Earth manufacturing methods, capabilities to utilize lunar resources, and mass-efficient design paradigms. The goal is to establish foundational technologies for producing future structures in their native environments using local resources. The Defense Sciences Office at DARPA will administer the program.
