"This amazing mission will be a treasure trove of unique data for astronomers," said Thomas Zurbuchen, associate administrator for NASA's science mission directorate.

And SPHEREx will be able to create a stellar map of the sky in 96 different colour bands -- an unprecedented resolution -- providing future NASA missions, such as the James Webb Telescope, with new targets for further study. Every six months, it will survey the entire sky "using technologies adapted from Earth satellites and Mars spacecraft."
