Collaborative & Assistant Systems


As NASA missions become longer and more scientifically complex, the critical challenge of managing the data and information generated by the Agency’s varied scientific and engineering activities only increases in importance. The Collaborative & Assistants Systems (CAS) technical area tackles this challenge by applying its extensive data management research and development experience to address the specific needs of NASA missions, programs, and projects.

CAS focuses its efforts on building systems and developing techniques that address issues throughout the information management lifecycle – starting with data acquisition, and moving through data conditioning and integration; data storage, organization, and access; data visualization; and finally, data analysis, mining, and extraction. An underlying theme of CAS work involves enabling NASA’s distributed teams to rapidly access key information needed for collaboration and accomplishment of their missions.
