Invocon on STS-118

August 8 – 21, 2007

Space Shuttle Endeavour

This was the twenty-fifth flight of Invocon hardware on the Space Shuttle. During STS-118 mission, the Endeavour crew installed the EWIS Antenna that will be used with the EWIS NCU when it is activated during a later mission. Two IVC systems were present on the orbiter and one was delivered to the ISS for use later.

Below is a list of the IVC systems that were present on Endeavour during the mission. The EWB MicroTAU-WLE system is the IVC system used for detecting impacts on the leading edge of the Orbiter’s wing.

This is the sixth flight of the EWB MicroTAU system, a high-speed data acquisition network for dynamic acceleration sensing and recording. On STS-118, 44 units were used to detect, locate, and characterize impacts on the RCC panels on the wing leading edge.
