Rank 108 celebrates the Nancy Grace Roman Space Telescope — NASA's planned wide-field infrared observatory launching by September 2027 on Falcon Heavy, carrying a 2.4 m primary mirror donated from NRO surplus and instruments designed to survey the sky 1,000 times faster than Hubble over areas 100 times wider. Led by Mark Clampin and Julie McEnery at Goddard, Roman (formerly WFIRST, renamed in 2020 for Nancy Grace Roman — the 'Mother of Hubble' who championed space astronomy at NASA for decades) will map billions of galaxies for dark energy research, detect 1,000+ exoplanets via microlensing, and demonstrate coronagraph technology for future Earth-like imaging. The Wide-Field Instrument and Coronagraph Instrument encode the next chapter of Great Observatories lineage after Hubble and JWST. Wallimilist renders the honeycomb gold mirror, engraved barrel illustration, microlensing curve overlay, and cream-column typography exactly as the master PNG dictates — observatory navy palette, NANCY GRACE ROMAN foil title, and curator copy on the WFIRST rename and survey-speed revolution.
