NASA’s SPHEREx, PUNCH Missions Live Coverage Begins

Good evening, and welcome to 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!

The SPHEREx mission will search for key ingredients for life in our galaxy and improve our understanding of how the universe evolved. The PUNCH mission will reveal how the Sun’s corona gives rise to the solar wind and space weather that surround our home planet.

We’re counting down to launch of these two NASA science missions aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. Liftoff is targeted for 11:10 p.m. EDT (8:10 p.m. PDT).
