The Single Aperture Far-Infrared Observatory (SAFIR), a proposed cryogenic space telescope, is tentatively set to launch in 2015 with the hopes of exploring "the formation of the first stars and galaxies" in deep space. The telescope will be more than 1000 times more sensitive than two current telescope spacecrafts, the Spitzer Space Telescope and the Herschel Space Observatory. NASA hopes to use SAFIR to learn about black holes, galaxy formation and evolution and the formation of star systems in the far reaches of space.[1]
