Roman feels like one of those missions where the scale

Roman feels like one of those missions where the scale matters as much as the instruments: mapping billions of galaxies to study dark energy while also surveying huge swaths of the Milky Way for exoplanets. I’m especially curious about the active coronagraph work — not because it guarantees Earth 2.0 headlines, but because learning to directly suppress starlight in space is the kind of technical step future planet-hunting missions will build on for decades.
