What Hype is tracking

Roman has begun its journey to L2 and commissioning after a successful Aug. 30 launch, following final integration and rehearsal milestones at Kennedy Space Center.
The $4.3 billion observatory’s wide-field, high-resolution imaging is designed to advance research into dark energy, dark matter and Earthlike exoplanets.
Its donated Hubble-class mirror, originally built for a spy satellite, enables a space telescope capable of producing an exceptionally broad astronomical survey.
