Abstract

Three generations of the Miniature X-ray Solar Spectrometer (MinXSS) have flown on small satellites with the goal "to explore the energy distribution of soft X-ray (SXR) emissions from the quiescent Sun, active regions, and during solar flares, and to model the impact on Earth's ionosphere and thermosphere". The primary science instrument is the Amptek X123 X-ray spectrometer that has improved with each generation of the MinXSS experiment. This third generation MinXSS-3 has higher energy resolution and larger effective area than its predecessors and is also known as the Dual-zone Aperture X-ray Solar Spectrometer (DAXSS). It was launched on the INSPIRESat-1 satellite on 2022 February 14, and INSPIRESat-1 has successfully completed its 6-month prime mission. The INSPIRESat-1 is in a dawn-dusk, Sun-Synchronous Orbit (SSO) and therefore has 24-hour coverage of the Sun during most of its mission so far. The rise of Solar Cycle 25 (SC-25) has been observed by DAXSS. This paper introduces the INSPIRESat-1 DAXSS solar SXR observations, and we focus the science results here on a solar occultation experiment and multiple flares on 2022 April 24. One key flare result is that the reduction of elemental abundances is greatest during the flare impulsive phase and thus highlighting the important role of chromospheric evaporation during flares to inject warmer plasma into the coronal loops. Furthermore, these results are suggestive that the amount of chromospheric evaporation is related to flare temperature and intensity., Comment: 44 pages including 19-page Appendix A, 8 figures, 7 tables

Abstract

Most nano-satellite and small satellite missions are designed for 400 km or higher altitudes. This is because small satellites, with mass, volume and power constraints, have limited propulsion capabilities to counteract the high aerodynamic drag in lower altitudes. Thus little or no science data has been gathered in-situ in the altitude range of 200 to 300 km by small satellite missions. INSPIRESat-4 (IS4) Atmospheric Coupling and Dynamics Explorer (ARCADE) is a ring-deployed 27U spacecraft that aims to bridge this gap by achieving a sustained flight in the VLEO (Very Low Earth Orbit) region to make in-situ Ionospheric plasma measurements. This paper first describes the science motivation of the mission. INSPIRESat-4 carries three payloads which are AtmoLITE (a Spatial Heterodyne Interferometer for upper-atmosphere temperature measurements), CIP (Compact Ionospheric Probe) for in-situ plasma measurements and an RGB Imager for high resolution imagery from VLEO. In this paper, the mission design for the VLEO mission is described in detail including analysis conducted for orbital lifetime prediction, attitude maneuvers and power generation. The paper concludes with a brief overview of the various subsystems including Command & Data Handling (C&DH) system , Electrical Power System (EPS), Flight Software (FSW), Communication system and Attitude Determination and Control System (ADCS). Published version We acknowledge funding agencies in Singapore, India and Taiwan for their grants for building the mission.
