Abstract : The Spectroscopic Investigation of Nebular Gas (SING) is a Near Ultraviolet (NUV) (1400-2700Å) imaging spectrograph being designed and developed at the Indian Institute of Astrophysics (IIA). SING was selected by the United Nations Office for Outer Space Affairs (UNOOSA) under an announcement of opportunity to fly scientific payloads onboard the upcoming Chinese Space Station (CSS). Opto-mechanical design, optimization and tolerancing of the SING have been completed. Designs of payload adapter assemblies and robotic arm interface are in progress; stringent volume considerations restrict the optomechanical design of various subsystems. In this work, we present the finite element analysis and thermal modelling of the SING payload and its interfacing units.
