Physical Oceanography Distributed Active Archive Center (PO.DAAC).

Middle school students take and study images from the International Space Station (ISS EarthKAM).

Planetary science and engineering data archive design, access and tools (Planetary Data System Engineering and Imaging Nodes).

The data accountability capabilities within Division 38, for both the science and engineering communities, provide an important mechanism to determine the state of the instrument, science observation, command and telemetry processing, and authorized data access. The ability to trace data packets through the end-to-end data stream, ground and flight systems, provides visibility required to evaluate process execution for product generation and eventual distribution. Determining the root cause of telemetry received on the ground, e.g., the on-board command executed or fault protection response that triggered telemetry, provides information important to trouble shoot anomalies, trend instrument performance, and update instrument and environmental models.

Science data distribution is accomplished through systems that provide high-performance file exchange services. These Java™-based systems maximize portability for both the client and server and provide secured file exchange supporting file queries and reliability verification. The content-independent file management system is compatible with full data accountability through the use of transaction-oriented file registration and distribution. Files are organized and processes are invoked using user-defined file types and entry-exit points compatible with the distribution system.

NASA's Planetary Data System and Physical Oceanography Distributed Active Archive Center (PO.DAAC; a part of the Earth Observing System Data Information System - EOSDIS) are responsible for providing archive and distribution support for NASA's missions and science communities. Science data products, for Earth, planetary, and astrophysics missions, are generated consistent with archival standards set by the scientific research community and managed by the PDS and EOSDIS. Managers of the PDS Engineering Node (EN), PDS Imaging Node (IN), and PO.DAAC are a part of the Instruments and Science Data Systems Division. This resident expertise has resulted in a close working relationship with interested scientists while providing a direct path to meeting project and science expectations for data archive and accessibility.
