NASA's SPHEREx mission aims to map the entire sky four times over a two-year span, focusing on studying galaxy formation and evolution. The mission involves scanning objects in 102 infrared colors, but there are concerns regarding the operational limitations due to coolant use for infrared scanning. Additionally, the longevity of the project could be at risk depending on NASA's science budget amidst future funding cuts. The mission provides essential data that could significantly enhance our understanding of the universe's history.
