Christopher Di Taranto, a member of the mechanical structures engineering team on the Jacobs Test and Operations Contract, stands in front of an Interim Cryogenic Propulsion Stage (ICPS) mockup during the Space Launch System avionics handling tool demonstration inside Kennedy Space Center’s Vehicle Assembly Building on April 4, 2019. The demonstration showed that avionics boxes could be successfully mounted into the SLS rocket’s upper stage safely, and with low risk of damaging a closely located hydrazine tank. Avionics boxes include the Inertial Navigation and Control Assembly and flight batteries. Di Taranto led a team to quickly resolve a non-conformance issue with the tool.
