TY - CHAP A1 - Hudec, Rene A1 - Döhring, Thorsten T1 - Astrophysical and scientific payloads for CubeSats T2 - 18th Pico- and Nanosatellite Workshop 2025, Abstracts Book N2 - For scientific and commercial applications, CubeSats enable cost-effective missions and significantly reduce the time between mission concept and launch compared to classical large satellites. Since 2000, there has been an accelerating increase in CubeSat launches, which in turn is expected to drive up the demand for dedicated optical instruments, especially in commercially relevant areas like high-resolution optics for earth observation. We present some studies and ideas of application of CubeSats mainly in the field of astronomy and astrophysics elaborated and studied at the Czech Technical University in Prague in collaboration with Aschaffenburg University of Applied Sciences. These includes single CubeSats as well as tandem CubeSat constellations. These miniature satellites can carry miniature scientific payloads for high-energy observations of both astrophysical objects as well as targets in high earth atmosphere. The examples include miniature X-ray and UV telescopes monitors and cameras, but also optical and NIR payloads. Due to the recent progress in satellite control engineering, tandem flight arrangements of mini-satellites are currently in discussion and under consideration for future space missions. CubeSat technologies offer an interesting possibility for space-born telescope payloads based on this approach. In such scenario, two small satellites will fly at a constant distance of a few meters up to 100 meters. Thereby, the front satellite will carry the telescope optics and the second satellite the detector system. The tandem flight arrangements are crucial for design of space telescopes with larger focal distances exceeding the typical sizes of small satellites.

We will discuss the possible miniature X/EUV and UV telescopes and monitors as potential minisats payloads. The advanced electronics image detectors allows the size of the optics to be miniaturized, still providing valuable scientific results.
