Deep Space Climate Observatory (DSCOVR) – Mission Objectives
The primary operations objective of the DSCOVR mission is to provide solar wind thermal plasma and magnetic field measurements to enable space weather forecasting by NOAA.

Secondary science objectives are to image the Sun lit disk of Earth in 10 spectral bands with a spatial resolution of 12 km or better, to determine ozone, aerosol, cloud cover, cloud height, vegetation, and leaf area indices and to measure the Earth reflected irradiance in the wavelength range of 0.2 - 100 microns.

DSCOVR Status and Issues

Major Programmatic Changes since last briefing:
USAF awarded a task order contract to Space X for a Falcon 9 v1.1 November 2012
Launch scheduled Early FY15
NASA Earth Sciences Division reprogrammed FY2013 funds allowing the EPIC and NISTAR sensors to be re-integrated onto the satellite
NOAA received a Sequestration reduction in funding to the program in FY2013 resulting the in new launch date

Project status:
DSCOVR KDP-C successfully occurred on August 27, 2013
Recalibration of solar wind sensors is complete
Satellite integration is near completion
Environmental testing will begin in Dec 2013/Jan 2014
Magnetic cleanliness testing has been successfully completed
