SOLID STATE LIGHTING MODULE, STATION DETAILED TEST OBJECTIVE 15008U (SSLM, SDTO
15008U)
Research Area: Technology Development and Demonstration: Life Support
Systems and Habitation
Expedition(s): 18
Principal Investigator(s): ● Daniel Shultz, NASA’s Kennedy Space Center, Cape Canaveral,
Florida
RESEARCH OBJECTIVES
The Solid-State Lighting Module
(SSLM), SDTO 15008U is a Station
Development Test Objective
sponsored by the National
Aeronautics and Space
Administration (NASA) to
demonstrate the advantages of
Light-Emitting Diode (LED) lighting
systems within the spacecraft
environment.
EARTH BENEFITS
Analysis of the crew evaluations
will be presented to several NASA
boards after data return. A final
report will be completed and archived for use in design of lighting systems in the next
generation of exploration vehicles.
SPACE BENEFITS
SSLM on the International Space Station (ISS) will begin the evaluation of LED lighting systems
for the next generation of crew exploration vehicles. SSLM will effectively evaluate potential
savings of LED technology vs currently installed systems.
RESULTS
The new solid-state lighting technology provides an important opportunity for re-lamping of the
ISS with an energy-efficient lighting system that has a significantly longer lifespan and does not
contain potentially toxic mercury vapor. A prototype Solid-State Lighting Assembly (SSLA) was
developed at NASA’s Kennedy Space Center and successfully installed on the ISS during
Expedition 18. This new lighting system will provide multiple settings that can support
astronaut vision and potentially serve as a lighting countermeasure for sleep and circadian
disruption aboard the ISS.
