Passive Thermal Design of a Thermal Infrared Telescope

The Deployable Space Telescope (DST) project aims to reduce the stowed volume compared to other Earth observation satellites with a similar resolution. The DST demonstrator functions in the thermal infrared (TIR) domain, which imposes stringent thermal requirements on the detector. The detector must be cooled to 150 K, and the instrument box to...

Design, Construction and Validation of a secondary mirror deployment mechanism for a thermal infrared space telescope

The miniaturization of satellites throughout the decades is mostly contributed by the advancement in electronics and technology. Volume and mass of a satellite are factors of the launch costs. The Deployable Space Telescope (DST) program<br/>aims to reduce the stowed volume of the telescope and subsequently reduce the costs.<br/>Telescopes have...

Deployable Space Telescope: Redesign of the secondary mirror support structure

The need for higher spatio-temporal resolution Earth observation increases rapidly. To fill this need, the Deployable Space Telescope (DST) project aims to make a light-weight, low-volume deployable telescope. In doing so, the achievable ground resolution is high while the cost per telescope stays low. This allows for the DST to be used in...
