The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
Gaia astrometry remains consistent with a binary origin for long secondary periods once sample contamination by semi-regular variables is accounted for.
