Overview
- The Roman telescope launched from Kennedy Space Center on Sunday, Aug. 30, 2026, separated from its Falcon Heavy upper stage, deployed solar arrays and a lower sunshield, and is transmitting telemetry as it travels to Sun–Earth L2.
- NASA plans a roughly three‑month commissioning and transfer to L2 during which teams will deploy the high‑gain antenna, perform two trajectory corrections, activate the coronagraph demonstrator first, and then power up and calibrate the Wide Field Instrument.
- The Wide Field Instrument is a 300‑megapixel infrared camera with a field of view at least 100 times larger than Hubble’s, enabling surveys of more than a billion galaxies and rapid, large‑area mapping that will feed targeted follow‑ups by Webb, Euclid, and Rubin.
- Coverage cites large daily data flows for the mission, with published estimates ranging from about 1.4 terabytes to roughly 11 terabytes per day, creating a public archive that will rely on automated tools and community analysis to find discoveries.
- Roman was built on hardware repurposed from an NRO spy‑satellite program, cost roughly $4.0–4.3 billion, and carries a coronagraph technology demo that will inform future missions while its primary five‑year science program could be extended toward a decade if fuel and systems allow.
