<li><strong>When:</strong> Feb. 28 @ 10 a.m. - 5 p.m.</li>
<li><strong>Topic:</strong> Illuminating Engineering Society</li>
<li><strong>Summary:</strong> Join us for a day of illumination with the Illuminating Engineering Society. Engage with engineers in Astronaut Gallery, sit in on panels about spacecraft engineering and lighting difficult environments and see a keynote presentation by Dr. George Brainard, director of the Light Research Program at Thomas Jefferson University. </li>
</ul>
<h3><strong>Schedule</strong> </h3>
<h4 style="margin-bottom:0px;"><strong>Engage in engineering exercises</strong></h4>
<em>Astronaut Gallery | 10 - 11 a.m.</em>
<ul>
<li><strong>The problem with lumens:</strong> In this exercise, we have a lamp stand that has a standard Edison base and standard bulb type. The lamp stand has the ability for us to put different reflectors over the lamp to redirect the energy from the lamp. The lamp’s lumen output stays the same, but the demonstration shows that the beam pattern matters. Find out why beam patterns are just as important as energy output in planning a lighting solution.</li>
<li><strong>Color Fidelity:</strong> In this exercise we have a table that has multiple lamps, some all-white LED, some multi-spectral LED, and some with different IES-TM30/CRI scores. We also have color samples from say a Munsel Color Book or even paint chips from the hardware store. Look at the same set of samples under the different light types and use a hend held spectral irradiance meter to learn why color fidelity scores matter.</li>
<li><strong>Light Level and Adaptation:</strong> The demonstration would be able to have variable intensity from say 100 lux to 1000-10000 lux. Complete a task and adapt to a very light bright level and then try to imediately do the same task at a lower light level. Gain an understanding of of how light levels affect everything from stree lighting to orbital lighting environments. </li></ul>

<h4 style="margin-bottom:0px;"><strong>Spacecraft Engineering Systems & Architecture</strong> </h4>
<em>Mission Briefing Center | 12 - 1 p.m. </em>
<ul>
<li><strong>Synopsis:</strong> Get a glimpse into the planning and stratgey that goes into designing a spacecraft, including the lighting environment.</li>
<li><strong>Speaker:</strong> Toni Clark, PE, NASA JSC HHPC Fellow for Spacecraft Lighting Environments at Leidos, Inc.</li>

<h4 style="margin-bottom:0px;"><strong>Light and Health: from Space Flight to Patient Care </strong></h4>
<em>Mission Briefing Center | 2 - 3 p.m.</em>
<ul><li><strong>Synopsis:</strong> Light is a potent stimulus for regulating human biology and behavior as well as fostering health in clinical applications, such as treating winter depression and sleep disorders. In addition, light therapy has been evaluated for healthy individuals who experience circadian and sleep disruption associated with intercontinental jet travel, shift work and spaceflight. Studies are in process testing an advanced solid-state light system for supporting astronaut vision as well as circadian, and sleep regulation in crewmembers on the International Space Station. These exciting advances are in a nascent stage, but collaborations between scientists and engineers across the fields of physics, biomedicine, lighting and architecture are opening the door to optimize the use light for the benefit of humanity</li><li><strong>Speaker:</strong> George C. Brainard, PhD, Director of the Light Research Program at Thomas Jefferson University</li></ul>

<h4 style="margin-bottom:0px;"><strong>Lighting for Difficult Environments</strong></h4>
<em>Mission Briefing Center | 3:30-5 p.m.</em>
<ul><li><strong>Synopsis:</strong> Panelists represent a wide variety of professions that all are impacted and study lighting for a variety of reasons. This panel discussion will delve into hypothesis they’ve tested, interesting discoveries they’ve made and impacts those have had to their lives and work.</li><li><strong>Speakers:</strong> Ian Ashdown, PE (Ret.), FIES, Senior Scientist at SunTracker Ltd.; Dr. George Brainard, PhD, Director of the Light Research Program at Thomas Jefferson University; Dr. Lee Brown, MD, Health System Sleep Disorders Center at the University of New Mexico, Tenured Prof of Internal Medicine and Pediatrics, Adj.
