Tail Service Mast Umbilical (TSMU) Drop Test

Preparations are underway to conduct a drop test of the Tail Service Mast Umbilicals (TSMU) for NASA’s Space Launch System (SLS) rocket on the mobile launcher in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on June 19, 2019. The 35-foot-tall TSMUs will connect to the SLS core stage aft section and provide liquid oxygen and liquid hydrogen fluid lines and electrical cable connections to the core stage engine section to support propellant handling during prelaunch operations. The drop test is being performed to ensure that the umbilicals will disconnect before launch of the SLS carrying Orion on its first uncrewed mission, Artemis 1, from Launch Complex 39B. Exploration Ground Systems and Engineering are completing the tests.
