Telescope archives are commonly perceived as static entities that store stale observations. In this talk we reimagine the humble telescope archive as a dynamic and resilient entity capable of responding to the rapidly evolving operational challenges facing observatories. Apart from the environmental spectres of climate change and pandemics, key challenges include coordinating multi-telescope observations of the imminent deluge of transients and facilitating equitable access to reduced science-ready data products. Addressing all these challenges requires the adoption of a sustainability mindset and embedding novel software components within the telescope archive. A notable example of the latter may include a Pipeline As a Web Service (PAWS) to enable on demand reduction of archival data, but other components interacting with transient brokers and telescope schedulers may be envisaged. We introduce a series of measures that could help transform telescope archives into active participants of a sustainable observatory ecosystem.
