NOAA Partnered - Planned
Deep Space Climate Observatory (DSCOVR):
• Partnership with NASA to refurbish DSCOVR satellite to meet Solar Wind mission, and USAF to provide the launch vehicle.
• DSCOVR will continue the solar wind measurements currently performed by magnetometer and plasma sensors on NASA’s Advanced Composition Explorer (ACE) satellite.
Schedule & Milestones: • FY 2014: Perform Spacecraft and Sensor Environmental Testing• FY 2015: Launch Spacecraft• FY 2015-2019: Operations and Maintenance
Orbit:‘Halo’/Lissajous orbit at L1. DSCOVR spacecraft will have consumables for 5 years.
Objectives: The DSCOVR mission main objective is to continue solar wind measurements in support of space weather requirements. The secondary objectives are to image the Sun lit disk of Earth for ozone, aerosol, cloud cover, cloud height, vegetation, and leaf area indices and to measure the Earth reflected irradiance.
Instruments:• Plasma –Magnetometer
(PlasMag): Magnetometer and Faraday Cup
• Electron Spectrometer• Earth Polychromatic
Imaging Camera (EPIC)• NIST Advanced
Radiometer (NISTAR)• Pulse Height Analyzer
(PHA)

DSCOVR Updates
• Observatory– Spacecraft and Sensors are fully integrated.– Successfully completed all Observatory Environmental testing.– Observatory scheduled for November 2014 shipment to Launch site.
• Ground System– Mission Operations Center (MOC) completed.– Hardware/software releases and testing on schedule to support launch/operations
with the Operational Readiness Review (ORR) scheduled for November.– Radio Frequency (RF) compatibility testing with NASA networks completed.– NASA networks will continue to provide support for DSCOVR activation and
checkout until NOAA ground antenna is certified during DSCOVR transit to final orbit at L1 prior to system handover to NOAA.
• DSCOVR on schedule for 23 January 2015 Launch Readiness Date

SWPC provides data with high reliability to preferred customers via the External-Space Weather Data Store (E-SWDS)• E-SWDS is a SQL Server• E-SWDS data is replicated in real-time
from the SWPC operational server • Air Force partners already use E-SWDS to
access RTSW data from ACE• SWPC has provided SWAFS with access to
DSCOVR test data via E-SWDS
