<p>New developments in the space industry, falling costs and a diversity of launch platforms are altering the conditions of access to space. The thesis examines to what extent cultural practice is enabled by these new relations. A brief historical overview details the cultural use of space and highlights the history of art satellites. This provides context for a detailed discussion of a satellite artwork by the author, "The Weight of Information". Auto-ethnographic and design-ethnographic techniques are used to explore the artwork through four situations. The setting of interfaces, form factors, boundaries and miniaturisation are found to be enabling mechanisms for cultural practice in space, while the developing space debris regulatory environment is found to provide a practical limit to further miniaturisation of space craft. The tension between the personal and infrastructural is examined through different concepts of entanglement. Strategies of tragedy, participation and correspondence that address issues of accessibility and contingency specific to cultural practice in the orbital environment are explored. Recommendations are made for practitioners wishing to work with art satellites. It is concluded that new developments in the space industry are enabling of future cultural practice in space. </p>

The shrinkage in sizes of components that make up satellites led to wider and low cost availability of satellites. As a result, there has been an advent of smaller organizations having the ability to deploy satellites with a variety of data-intensive applications to run on them. One popular application is image analysis to detect, for example, land, ice, clouds, etc. However, the resource-constrained nature of the devices deployed in satellites creates additional challenges for this resource-intensive application.In this paper, we investigate the performance of a variety of edge devices for deep-learning-based image processing in space. Our goal is to determine the devices that satisfy the latency and power constraints of satellites while achieving reasonably accurate results. Our results demonstrate that hardware accelerators (TPUs, GPUs) are necessary to reach the latency requirements. On the other hand, state-of-the-art edge devices with GPUs could have a high power draw, making them unsuitable for deployment on a satellite.
