First Stage Fueling Started

Moments ago, mission teams polled “go” to begin fueling the SpaceX Falcon 9 first-stage booster.
NASA just began its live broadcast coverage of tonight’s launch of the agency’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) and PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions.
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.
Launching as a rideshare with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), the agency’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission is a constellation of four small satellites that will make global, 3D observations of the Sun’s outer atmosphere, the corona.
Launching with NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites, NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way.
We’re about 90 minutes away from tonight’s launch of NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) and PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
Welcome to tonight’s live launch coverage of NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) and PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions!
NASA and SpaceX are standing down from today’s launch attempt of a Falcon 9 rocket carrying the agency’s SPHEREx and PUNCH missions due to weather at the launch site and a SPHEREx ground data-flow issue.
NASA just ramped up its coverage of today’s launch of NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) and PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions, as the live broadcast with commentary has now begun.
We’re a little under an hour and a half away from today’s launch of NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) and PUNCH (Polarimeter to Unify the Corona and Heliosphere) missions.
