Watch a LIVE news conference ahead of the launch of NASA's next mission. The SPHEREx space telescope will survey the sky in optical and infrared light, gathering data on more than 450 million galaxies, and 100 million stars in our own galaxy. PUNCH will use four suitcase-sized satellites in low Earth orbit to observe the Sun, and tell us more about the space weather that can impact communications on Earth.
