NASA’s SPHEREx space telescope has begun its mission to map the entire sky in 3D
The SPHEREx observatory is on a 25-month mission to map the sky in unprecedented color, observing 102 wavelengths of infrared light.
SPHEREx, which launched in early March, got started with its observations this past week after over a month of setup procedures and system checks, according to NASA. The space telescope will complete about 14.5 orbits of Earth per day, capturing roughly 3,600 images daily and observing the sky in an unprecedented 102 wavelengths of infrared light. The spacecraft “orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky,” NASA explains.
