NASA fuels its next-gen Roman Space Telescope for August launch

NeRD

NASA announced on Tuesday (July 28) that it has officially fueled-up the Roman Space Telescope — a magnificent new observatory expected to generate over 500 terabytes of cosmic data per year. By comparison, the Hubble Space Telescope, in its 35 years of service, has created over 400 terabytes in total. At present, the Roman Space Telescope‘s launch aboard a SpaceX Falcon Heavy rocket is scheduled to occur on Aug. 30 at 7:26 a.m. EDT (1126 GMT). And considering the project is sort of the gold-standard for telescope-building, as the team…

Starship in space! See highlights of SpaceX megarocket’s epic Flight 13 test launch (video)

NeRD

The 13th test flight of SpaceX’s Starship megarocket went pretty well — and provided some amazing visuals, too. Flight 13 launched on Friday (July 24), sending the 408-foot-tall (124 meters) Starship Version 3 (V3) vehicle aloft from SpaceX’s Starbase site in South Texas. Starship’s Super Heavy booster had some engine issues on its way back to Earth. But the Ship upper stage hit all of its marks, successfully deploying 20 next-gen Starlink satellites, re-igniting one of its Raptor engines in space as planned and splashing down softly off the coast…

NASA Science Soars During August Total Solar Eclipse

NeRD

6 min read NASA Science Soars During August Total Solar Eclipse Each time the Moon covers the Sun during a total solar eclipse — darkening daytime skies and briefly revealing the Sun’s ethereal outer atmosphere, the corona — it presents new opportunities to better understand our star and its influence on Earth. On Wednesday, Aug. 12, as the next total solar eclipse sweeps over Greenland, Iceland, and Spain, NASA-funded science teams will be chasing the Moon’s shadow with a high-altitude jet and scientific balloons to investigate the Sun’s dynamics and…

NASA’s Swift Sees ‘Wandering’ Mega Black Hole Shredding Star

NeRD

This artist’s concept depicts a tidal disruption event, which occurs when a star passes fatally close to a supermassive black hole. Crumbs of the splintering star heat up as they swirl around the black hole, creating a glow astronomers can see from far across the cosmos, and the black hole launches a relativistic jet into space. NRAO/AUI/NSF/NASA NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a faraway galaxy. These phenomena are rare to begin with, and none…
