Watch the pre-launch science for NASA's SPHEREx and PUNCH missions.
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.
Participants in this science briefing include:
Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters
Joe Westlake, director, Heliophysics Division, NASA Headquarters
Nicholeen Viall, PUNCH Mission Scientist, NASA’s Goddard Space Flight Center
Rachel Akeson, SPHEREx science data center lead, Caltech/IPAC
Phil Korngut, SPHEREx instrument scientist, Caltech
