On April 22, 2017, members of the ICON team showed off a life-size 3D-printed ICON payload mock-up—built by Space Dynamics Lab—at Lawrence Hall of Science (LHS) for Cal Day, UC Berkeley’s all-day Open House. PI Thomas Immel was on hand to answer questions. Nearly 1500 visitors, primarily families, made the extra trip up the hill from campus (where most activities were happening) to LHS and through the main hall, where the life-size model and other ICON outreach activities were featured.
