March 2: NASA may launch the SPHEREx mission to survey the sky in 102 colors.
If astronomers could study space in more colors, they'd gain a better understanding of cosmic physics and planetary science. That's the goal of NASA's SPHEREx mission, imaging the sky in 102 colors, many of which are infrared and aren't visible to humans. SPHEREx stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. Another mission to study the sun's corona, PUNCH or Polarimeter to Unify the Corona and Heliosphere, will share the ride to space with SPHEREx.
