PUNCH Satellites Solar Array Deployment Test

Crews conduct a solar array deployment test on the spacecraft of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located on Vandenberg Space Force Base in California on Tuesday, Jan. 21, 2025. The four satellites of PUNCH will make 3D observations of the Sun’s corona to learn how the mass and energy becomes solar wind. PUNCH, along with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), a space telescope, will launch aboard a SpaceX Falcon 9 rocket in late February 2025.
