FreeSat: Enabling Astronomical and Earth Observations low-cost Space-born telescope access times with the use of free-form optics“

Due to the scientific objectives restrictions, high costs and limited observation times available, scientists cannot truly benefit from access to space-born or ground-based astronomical observations and therefore astronomical research results remain limited. Additionally, there currently is a gap of space-borne telescopes in the spectral range spanning from UV to SWIR. This spectral range is largely not accessible from ground and must therefore observed from Space. A successful example of space-born UV telescope was “The Galaxy Evolution Explorer (GALEX)”, which was launched on April 28, 2003 and operated until early 2012. Space-borne telescopes in the UV range are being successfully used for Earth Observation. As example, a range of air pollutants can be inferred from satellite UV spectroscopy measurements by using the unique absorption signatures of pollutants, in particular petroleum pollutants. The telescope built for Astronomical observation would be a pathfinder for a second mission for Earth Observation, by using the same technologies and with only minor hardware and software modifications. Our project objective is to build small telescopes in the UV spectral range by using freeform optics. A small telescope can be integrated on a small satellite (even a cubesat) allowing therefore significant savings for its launch. We also aim at reducing satellites operational costs by using to the recent advances in automated operations capabilities and smart data processing, and at reducing data dissemination costs via satellite backhauling technologies. In conclusion, by reducing overall mission costs we would be able to offer space-born telescope access time at an affordable price. OUR BUSINESS MODEL: to sell telescopes access time from satellites launched and operated by the Consortium. FREE-FORM OPTICS Free-form optics is a highly innovative technology recently used for optical systems for satellites for Earth observation.
