SPHEREx launched March 11 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California .

The observatory will begin its two-year prime mission after a roughly one-month checkout period.

Four small satellites that make up the agency’s PUNCH (Polarimeter to Unify the Corona and Heliosphere ) mission will study how the Sun 's outer atmosphere becomes the solar wind.

The mission will use a technique called spectroscopy to measure the distance to 450 million galaxies.

The PUNCH mission is designed to answer basic questions about how stars like our Sun produce stellar winds.

The data will be conducted by a team of scientists located at 10 institutions in the U.S. , two in South Korea , and one in Taiwan .

Data will be processed and archived at IPAC at Caltech , which manages JPL for NASA .
