Description
Space-based astronomy offers a unique opportunity to observe the celestial sphere, free from atmospheric distortions and absorptions, with the potential for almost continuous, uninterrupted observations. Traditionally, space-based telescopes have been developed and operated by large space agencies and institutions, resulting in very expensive missions with long development times. However, recent small satellite missions, like HaloSat, have demonstrated the potential to provide valuable astronomical data at a lower cost and with shorter development cycles. SuperASTRO is a novel small satellite concept equipped with a super-spectral imager developed by Surrey Satellite Technology Limited (SSTL) in collaboration with academic advisors from the University of Surrey. With the expected end of life and planned launches of current space astronomy missions, spectral bands between the wavelengths of 0.3 and 0.5 microns are anticipated to be uncovered by any other space telescope. The SuperASTRO imager is designed to be equipped with up to 66 filters covering spectral bands ranging from 0.3μm to 0.96μm to fill this gap in observations while showcasing the capabilities of small satellites in delivering valuable astronomical data. Additionally, the development of small satellites using SSTL's vertically integrated approach presents significant advantages in terms of cost and development time providing at the same time greater operational flexibility. This presentation will provide an overview of an internal study on potential small-satellite astronomy missions, which led to the development of SuperASTRO. It will highlight the innovations behind this concept and evaluate its feasibility, demonstrating its great potential for application in both institutional and commercial astronomy.
