## Current Heliospheric                                          Energetic Particle Environment

**Missions: ACE, IMP-8, Wind, SOHO, Stereo, Ulysses, Voyager, New Horizons**

## Challenges of Heliophysics Energetic Particle Environment

- Suprathermal (keV-MeV) and higher energy (MeV – GeV) 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

## SPASE Query Language Updates for EP?

## VEPO Approach Summary

- Apply EP instrument, data processing, and science analysis expertise from selected members of Heliospheric Network (HN) instrument teams
- Leverage VHO development and applicable SPDF data systems to support VEPO interface queries for primary and ancillary data sets
- Focus at highest priority on VEPO accessibility for existing data sets, also including any continuous updates, from operational HN missions
- Utilize existing SPDF and other data systems for provision of ancillary ephemeris and activity data if not available through primary data sets
- Incorporate legacy mission (e.g., Pioneer, Helios) and supporting neutron monitor data sets at medium priority as time and resources permit
- Defer work on multi-spacecraft and multi-sensor calibration, and on inclusion of non-HN planetary mission data, to other projects, e.g. Outer Planets Research
- Maintain substantial budget support for non-GSFC co-investigators with proportionately greater reductions on deferred work by core team at GSFC

## The Seven Pillars of VEPO

**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**

**Wadi Rum, Jordan**

- Reduced or deferred priorities on selected (e.g., planetary mission) existing data sets, and on value-added development of new intercalibrated data sets and OMNI-EP data system.

## VEPO will mainly utilize VHO existing middleware
