摘要

NASA contracted Neptec to provide the Laser Camera System (LCS), a 3D scanning laser sensor, for the on-orbit inspection of the Space Shuttle's Thermal Protection System (IPS) on the return-to-flight mission STS-114. The scanner was mounted on the boom extension to the Shuttle Remote Manipulator System (SRMS). Neptec's LCS was selected due to its close-range accuracy, large scanning volume and immunity to the harsh ambient lighting of space. The crew of STS-114 successfully used the LCS to inspect and measure damage to the Discovery Shuttle TPS in July, 2005. The crew also inspected the external-tank (ET) doors to ensure that they were fully closed. Neptec staff also performed operational support and real-time detailed analysis of the scanned features using analysis workstations at Mission Control Center (MCC) in Houston. This paper provides a summary of the on-orbit scanning activities and a description of the results detailed in the analysis.
