Open the Frontier to Space Environment Prediction
Understand the Nature of Our Home in Space
Safeguard Our Outward Journey
Understand the fundamental physical processes of the space environment – from the Sun to Earth, to other
planets, and beyond to the interstellar medium
Understand how human society, technological systems, and the habitability of planets are affected
by solar variability and planetary magnetic fields
Maximize the safety and productivity of human and robotic explorers by developing the capability to
predict the extreme and dynamic conditions in space

The Strategic Triad of Heliophysics Programs
• Theory
• Models
• DataChange over past five yrs:
• LWS TR&T: ~90$M invested
• Theory: ~3$M/year
• SR&T: 10% increase
• CCMC: significant investment toward model verification and other services
• Data environment: VxO & resident archive investment nearing fruition
New research has shown that electrons traveling at the speed of light are always present in solar particle eruptions. These electrons – traveling much faster than the hazardous solar energetic protons – follow the magnetic lines of force from the Sun to the Earth. Therefore, they can be used as a reliable early warning sign of hazardous radiation ahead.
Solar electrons reach the
Earth-moon system about
one hour before the solar proton
radiation hazard arrives.
New Space Weather Forecasting Tool from Heliophysics Science Program
EVA Abort Command Issued
This is an important example of the potential for further rapid transition of SMD Research to SOMD/ESMD Operations – May 2007 to Feb 2008 – this new prediction tool has entered V&V by the JSC/SRAG for future Shuttle, ISS, and CEV operations.
Empirical Forecasting Matrices Translate Solar Electron Data into +1h Proton Hazard Forecast (Posner, Space Weather, 2007)
Even in the case of the fastest-rising major proton event on record (Jan. 20, 2005), the electron precursor signal was detected 20-25 minutes in advance.
A one-hour warning has the potential to provide the advanced notice needed for efficient EVA planning.

In addition to the prime objective of discovering the composition of the solar corona, solar wind, local interstellar medium (ISM), galactic matter, ACE represents:
• a "gold-standard" for L1 Space Weather monitoring
• has resources to maintain ops beyond ~2024
• national effort required to maintain similar capability for the future
SoHO
AIM
C/NOFS
TWINS (2)
In addition to the prime objective of studying the Sun, from its deep core to the outer corona, and the solar wind:
• a prime source of near-real time solar data for space weather prediction (although not quite 24-7 beacon mode)
• intent is to maintain SW capabilities through the Bogart mode into the next decade
STEREO
AIM
C/NOFS
TWINS (2)
In addition to the prime objective of understanding the fundamental nature and origin of coronal mass ejections:
• near real-time SW beacon for images, in-situ particle and fields, and radio data
• Important SW asset until spacecraft move beyond contact horizon
• Research to Ops demonstration of importance of off-axis observations

Caution: not NASA prime assets!
• capability exists for real-time near-Earth space environment data
• Opportunity for inter-agency cooperation for supply of new type of SW data and operational models?
SDO
AIM
C/NOFS
TWINS (2)
In addition to the prime objective of understanding the how and why of the Sun's magnetic changes:
• real-time, full resolution access to solar irradiance data and the source of that irradiance
• anticipated to be important real-time SW asset to advance state-of-the-art predictions
• Research to Ops challenge of high resolution spatial, temporal, & spectral information
RBSP/MMS
AIM
C/NOFS
TWINS (2)
In addition to the prime objectives of these missions:
• Intent is to deploy SW beacons on these missions if deemed feasible, economical, and beneficial.
• Research to Ops challenge will be the adoption of a distributed sensor net coupled to large-scale data-assimilation space environment models.
