SSDs in Spaceborne Computer-2 for ISS Experiments

This technical brief discusses the application of KIOXIA SSDs in the HPE Spaceborne Computer-2, which is designed to conduct scientific experiments aboard the International Space Station (ISS). The document outlines the challenges of operating computers in space, such as radiation, microgravity, and constraints on size and power. It details how the Spaceborne Computer-2 utilizes various models of KIOXIA SSDs to facilitate data processing, analysis, backups, and redundancy. The SSDs are preferred over traditional hard disk drives due to their lack of moving parts, compact size, lower power consumption, and higher performance. The brief also explains the Technology Readiness Levels (TRL) framework used to assess the readiness of technologies for space missions, emphasizing that the deployed SSDs have achieved TRL-9 status. Additionally, it presents a use case involving AI-based analysis of astronaut gloves, highlighting the efficiency improvements in data transfer and analysis enabled by the Spaceborne Computer-2.
