    First Stage Fueling Started

    A SpaceX Falcon 9 rocket, carrying NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory and PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites, is vertical at Space Launch Complex 4 East from Vandenberg Space Force Base in California on Tuesday, March 11, 2025.

    Moments ago, mission teams polled “go” to begin fueling the SpaceX Falcon 9 first-stage booster.  We’re now just under 45 minutes from launch, and the rocket is being loaded with RP-1 (rocket grade kerosene). The rocket’s first stage also is being fueled with liquid oxygen, and a few minutes from now, fueling will begin for …

    Meet the Spacecraft: SPHEREx

    Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will create a map of the cosmos like no other. Using a technique called spectroscopy to image the entire sky in 102 wavelengths of infrared light, SPHEREx will gather information about the composition of and distance to millions of galaxies and stars. With this map, scientists will study what happened in the first fraction of a second after the big bang, how galaxies formed and evolved, and the origins of water in planetary systems in our galaxy.

    NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory, the size of a compact car, utilizes a wide-field aluminum telescope.  One of SPHEREx’s most striking features — its series of three nested conical photon shields — helps it stay cold and see faint objects. The mission’s infrared telescope …

    Weather Looks Favorable for Launch of SPHEREx, PUNCH Missions

    A SpaceX Falcon 9 rocket, carrying NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory and PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites, is vertical at Space Launch Complex 4 East from Vandenberg Space Force Base in California on Saturday, March 8, 2025. SPHEREx will use its telescope to provide an all-sky spectral survey, creating a 3D map of the entire sky to help scientists investigate the origins of our universe. PUNCH will study origins of the Sun’s outflow of material, or the solar wind, capturing continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system.

    Weather officials with the U.S. Space Force’s Space Launch Delta 30 are predicting over a 90% chance of favorable weather conditions for tonight’s launch. NASA is targeting 8:10 p.m. PDT (11:10 p.m. EDT) for launch of the SPHEREx and PUNCH missions atop a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg …
