Interface Region Imaging Spectrograph (IRIS) Passes Engineering Readiness Test 2

The Ground Data System (GDS) for the Interface Region Imaging Spectrograph (IRIS) mission passed its second Engineering Readiness Test (ERT2). ERT2 is a significant demonstration of the GDS capability. This test included receiving and transferring command inputs from the science team, assembling the command load, transmitting the load to the simulator, and monitoring responses from the flight software. The successful completion of this test demonstrates full GDS capability and functionality.

BACKGROUND: The IRIS mission is currently in development, preparing to launch in December of 2012. This mission will study the energy flow at the interface between the Sun’s chromosphere (the gaseous layers consisting primarily of hydrogen surrounding the Sun's photosphere) and corona. Ames is supporting the mission, including development of mission operations and the GDS.

NASA PROGRAM FUNDING: The Science Missions Directorate (SMD) Heliophysics Division, the Small Explorers Office, and the IRIS Mission

IRIS/MOS GDS TEAM: Mitchell Ai-Chang, Robert Carvalho, Darin Foreman, Brian Johnson, Tony Lindsey, Masoud Mansouri-Samani, Eddy Mazmanian, Scott Sawyer, Julie Stern, Helen Stewart, James Strong, and Peter Tran
