In a world where radial-velocity precisions are routinely measured in
centimetres per second, what becomes of sites that can deliver not "EPRV,"
but only "RV"? The detection of potentially habitable Earth-mass planets
orbiting the nearest stars is an audacious undertaking that requires
complementary data from less-precise instruments. I give an update on
TESS follow-up results from the Minerva-Australis array of four 0.7m
telescopes, and describe future plans for the facility. In the coming
decades, metre-class telescopes delivering RV precisions of a few m/s will
be able to do the critically necessary vetting of candidate systems.
These data include the detailed characterisation of stellar activity, the
refinement of orbits for larger planets in those systems, and the
exclusion of dynamically troublesome bodies near their habitable zones.
These aims require significant dedicated time on (P)RV instruments. EPRV
machines are necessary, but not sufficient, to fully understand the
planetary systems to be probed by the next generation of flagship space
telescopes.
