Astronomy is moving into the era of “big data”, a paradigm where data volumes will be reaching 10s PBs (ASKAP), and in the near future 100s PBs (SKA1). Science from the next generation of radio telescopes requires long term storage of the data and tools for querying and accessing the data. CSIRO IM&T and CASS have addressed this by building the CSIRO ASKAP Science Data Archive (CASDA) to provide long term storage for Australian SKA Pathfinder (ASKAP) data products, and the hardware and software facilities that enable astronomers to access the data. CASDA will store ~5 PB per year from ASKAP and serve that to astronomers around the world using both virtual observatory (VO) and web-based portal services. This paper will present the current status of CASDA and future development plans.


Minh Huynh graduated from ANU with a PhD in Astronomy and Astrophysics in 2005. She worked in NASA’s Spitzer Space Telescope and Planck Observatory teams at Caltech in Los Angeles, before moving back to Perth as Deputy International Project Scientist for the Square Kilometre Array at the University of Western Australia. The CSIRO is busy commissioning the Australian SKA Pathfinder (ASKAP), a next generation radio telescope. Now at the CSIRO in Perth, Minh continues astronomical research on radio galaxies while also preparing CSIRO’s ASKAP Science Data Archive for the big data deluge from ASKAP.


AeRO is the industry association focused on eResearch in Australasia. We play a critical coordination role for our members, who are actively transforming research via Information Technology. Organisations join AeRO to advance their own capabilities and services, to collaborate and to network with peers. AeRO believes researchers and the sector significantly benefit from greater communication, coordination and sharing among the increasingly different and evolving service providers.
