NASA's Nancy Grace Roman Space Telescope arrives at Kennedy Space Center ahead of Falcon Heavy launch

NASA’s Nancy Grace Roman Space Telescope has arrived at Kennedy Space Center, Florida, for final tests before an Aug. 30 liftoff aboard SpaceX’s Falcon Heavy—eight weeks earlier than originally planned. From Goddard, the telescope was shipped on a Pegasus barge to KSC, where it will be unpacked, decontaminated, and moved into the Payload Hazardous Servicing Facility for final checkouts, fueling, and integration in preparation for launch to Sun-Earth L2. The mission, powered by a historical 2.4-meter mirror and a 300-megapixel camera, aims to study dark energy, exoplanets, and other cosmic phenomena, with a nominal five-year primary duration and potential extensions if conditions allow.

Webb Survives 344 Failure Points, Now Runs on Less Power Than a Tea Kettle at L2

Launched with a list of 344 single-point failures, the James Webb Space Telescope avoided every one through a careful, unattended deployment. The sunshield’s successful unfolding and the mirror alignments minimized risk, enabling a mission at the Sun–Earth L2 point about 1.5 million kilometers from Earth. Remarkably, Webb now operates on roughly one kilowatt of power—about the same as a household kettle—thanks to passive cooling and shade, letting it conduct ultra‑sensitive infrared astronomy from a million miles away.

NASA's Roman Space Telescope Finishes Construction Ahead of Schedule and Under Budget

NASA has completed construction of the Nancy Grace Roman Space Telescope, finishing ahead of schedule and under budget, with a September launch aboard SpaceX Falcon Heavy to the L2 point. The telescope features a 7.9-foot primary mirror, a 300-megapixel Wide Field Instrument, and a Roman Coronagraph for exoplanet imaging; it will survey the sky 1,000x faster, observe 200x more of the sky per image, and process data 2,000x faster than Hubble, potentially discovering billions of galaxies and tens of billions of stars while expanding infrared astronomy and exoplanet discovery.
