Project 8 is a direct neutrino mass experiment that has developed a new technique, Cyclotron Radiation Emission Spectroscopy (CRES), to make a differential measurement of the tritium $\beta^{-}$ spectrum. Project 8 aims to use the advantages of CRES to surmount the systematic and statistical limitations of current-generation direct neutrino mass measurement methods, proceeding in a phased approach toward a goal of effective electron antineutrino mass sensitivity of ${\sim}$40 meV/c$^2$ using atomic tritium. This talk will report on the progress toward Phase III free-space CRES and atomic tritium demonstrations, which will enable the advances in energy resolution and statistics needed to achieve full Phase IV sensitivity.

This work is supported by the US DOE Office of Nuclear Physics, the US NSF, the PRISMA+ Cluster of Excellence at the University of Mainz, and internal investments at all institutions.
