Nasa postpones launch of two major space missions: SPHEREx and PUNCH

Nasa has postponed the launch of its SPHEREx and PUNCH missions scheduled on a SpaceX Falcon 9 rocket from California. The delay allows for further rocket checkouts. SPHEREx will scan the sky in infrared light to study galaxies and cosmic history, while PUNCH will investigate the sun's outer atmosphere and solar wind to improve space weather predictions.
