We will present on the status of a new NUV (3080 Å) miniature SHS instrument for detecting the hydroxyl OD/OH isotope ratio remotely in diffused and faint targets such as cometary tails, comae, and planetary exospheres. Developing the SHS instrument has a wide significance to Astrophysics and Planetary science. SHS provides integrated spectra at high R, over a wide FOV in compact designs that offer the ability to make key science measurements for a variety of planetary targets. Many planetary objects that produce UV emissions are angularly extended low brightness targets, i.e., solar wind charge exchange emission, solar system planetary atmospheres and exospheres, mapping atomic emission, comets, and the interplanetary medium. SHS could be implemented on a dedicated SmallSat or ISS that can sit and stare at its target for a long duration of time that cannot be done from the ground or on big missions.
