The Far-uv Off Rowland-circle Telescope for Imaging and Spectroscopy (FORTIS) will be flown for the second time on a mission to investigate Lyman alpha (Ly ) escape from nearby star- forming galaxies and to quantify its relationship to the local gas-to-dust ratio.

FORTIS uses a microshutter array (MSA), developed by NASA’s Goddard Space Flight Center for the Near-Infrared Spectrograph (NIRSpec) instrument onboard the James Webb Space Telescope (JWST). FORTIS expands the use of this technology from the near Infrared (NIR) to the far Ultraviolet (far-UV) range of the spectrum. The MSA is placed at the prime focus of an innovative yet minimalist Gregorian telescope, which uses a diffraction grating as the secondary optic. The ┬áicroshutter array allows acquisition of images over a 1/2 degree field-of-view and to autonomously target (on-the-fly) 43 different regions within the field for spectroscopic follow up in the 900 -- 1700 Angstrom bandpass.

This mission will study NGC 1365 also known as the Great Barred Spiral Glaxy in the constellation Fornax.
