The exposure above was taken at NASA ’s Goddard Space Flight Center in Greenbelt , Maryland . atomic number 6 dioxide flatulence turn into firm below −78.5 ° C ( −109.3 ° F ) temperature at Earth atmospheric press , and by fritter the soft , snowy cloth at the surface , applied scientist lightly clean large scope mirror , if they are contaminate during integration and testing .
“ The snow - like crystals ( carbon dioxide nose candy ) knock contaminate particulates and molecules off the mirror,”explainedLee Feinberg , NASA optical telescope element manager . Pretty shiver .
