Icy Clues

Scientists will search the Milky Way for icy granules of water, carbon dioxide, and other building blocks of life, helping to understand how these compounds contribute to planet formation.

Inflation Insights

The mission aims to analyze galaxy distributions to decipher the physics behind cosmic inflation, revealing what fueled the universe’s rapid expansion moments after the Big Bang.

PUNCH Mission

Launching alongside SPHEREx, NASA’s PUNCH mission will focus on the Sun, using four satellites to study the corona and how solar wind carries mass and energy across space.

Precision Orbit

SPHEREx, about the size of a subcompact car, will enter a polar orbit, scanning the sky like a globe to deliver comprehensive data on hundreds of millions of stars and galaxies.
