Two pioneers in human space flight, Yuri A. Gagarin and John Glenn are memorialized in contrasting media, a perforated stainless steel halftone image of John Glenn rendered as a contrast to a bronze of Yuri Gagarin donated by the Russian consulate.  Metalab, working with Architect Ron Witte and Artist Randy Twaddle developed a custom algorithm to render John Glenn’s iconic image aboard the Mercury Capsule by perforating the shape of the capsule in a staggered pattern with varying sizes to render light and dark tones. The image panels are delicately suspended on thin standoff rods connected to a powder coated steel frame.  Each figure stands on a shallow plinth edged in cor-ten steel, in an historic dialogue on the site of NASA’s first manned space flight headquarters, now occupied as the Houston Parks and Recreation headquarters.
