Challenges of Heliophysics Energetic Particle Environment • Suprathermal (ke. V-Me. V) and higher energy (Me. V – Ge. V) energetic particles (EP) pervade heliospheric and planetary magnetospheric regions from solar, heliospheric, planetary (Jovian e−), and galactic sources • EP and related cosmic ray research has many cross-disciplinary science applications in earth science, heliophysics, and astrophysics; e. g. ionization rates in planetary atmospheres, carbon radioisotope dating for archeology • There is high demand for EP data as expressed by participants in U. S. and international science forums (AGU, EGS, COSPAR, AOGS, ICRC, etc) hosting EP-related sessions • Many sources of EP data relevant to heliophysics research currently exist from instruments of the operational and legacy Heliospheric Network spacecraft fleet and from ground-based and high-altitude balloon platforms • Investigations of origins, transport, and interactions of EP require analysis of multi-sensor, multi-spacecraft data sets from diverse repositories in varied formats and with varying degrees of documentation for usability and validation • A common view of EP environments in the Earth-Moon geospace system and for interplanetary journeys to Mars and beyond is needed for radiation hazard modeling, assessment, and mitigation in support robotic and human missions for the NASA Vision for Space Exploration • Virtual observatories and SPASE have largely not fully addressed special characteristics and challenges of EP in the heliophysics data environment
What is a Virtual Observatory, according to NASA? “A Virtual Observatory (VO) is a suite of software applications on a set of computers that allows users to uniformly find, access, and use resources (data, software, document, and image products and services using these) from a collection of distributed product repositories and service providers. A VO is a service that unites services and/or multiple repositories. ” The Seven Pillars of Wisdom* for Vi. CRO Functions as a Vx. O 1. Coordinated Discovery and Access 2. Understanding of Data Needs 3. Standards and Metadata 4. APIs and Web services 5. Value Added Services 6. Ancillary Data Access 7. Usage Assessment and Provenance Protection *Wisdom hath builded her house, she hath hewn out her seven pillars (Proverbs 9: 1)
