The world is becoming more enthusiastic about exploring the space. In order to do exploration, we need to develop new technologies every single day that can help us to look far beyond our galaxy. We require devices that can help us to pinpoint far away objects in deep space precisely. We need detectors and remote sensors which can detect even a weak signal that is coming out from any celestial body from a faraway distance. For this purpose, detectors need to be made highly sensitive and accurate, that can be only possible when an instrument is operated at a cryogenic temperature. SAC-ISRO, is involved in research, development and demonstrations on the application of space technology in the field of remote sensing and satellite navigation. This includes research and development of cryocoolers that provides cryogenic temperature for detector operations. Stirling cryocoolers are used to cool down infrared detectors for many applications. We are going to design and develop integral type Stirling cryocoolers for space application detectors. It has advantages of higher efficiency compared to other cryocoolers, light weight. One of the disadvantage of Stirling cryocooler is vibration as it has two moving elements in each cylinder. It has to be reduced and to be made efficient, so that will help for large space observations for a long period of time.
