Artist's concept of Single Aperture Far-Infrared Observatory
› Larger view
The Single Aperture Far-Infrared Observatory, or SAFIR, is a proposed NASA mission to study the earliest evolution of galaxies, stars and planetary systems using a large cryogenic space telescope.
Designed as a follow-on to the Spitzer Space Telescope, the mission would use a single primary mirror more than five times the size of Spitzer's to detect and study objects previously masked by dust and other space debris.
