In this presentation we report on the development of a highly miniaturized Spatial Heterodyne Spectrometer (SHS) for the deployment on micro- and nano-satellites. The throughput of a SHS is orders of magnitude larger than of a conventional grating spectrometer of the same size. The goal is to deploy such an instrument on a CubeSat to measure the oxygen atmospheric band emission in the middle atmosphere. The instrument resolves individual rotational lines whose intensities follow a Boltzmann law allowing for the derivation of temperature from the relative structure of these lines. The CubeSat AtmoCube-1 is currently developed within the Development Initiative for Small Satellites Exploring Climate Processes by Tomography (DISSECT), initiated by the University of Wuppertal and the Research Centre Jülich. The remote sensing instrument will be tested under near space conditions within the experiment AtmoHIT (Atmospheric Heterodyne Interferometer Test). AtmoHIT is part of the Rocket Experiment for University Students campaign (REXUS 22), realized under a bilateral Agency Agreement between the German Aerospace Centre (DLR) and the Swedish National Space Board (SNSB).
