Image Analysts Use 3D Measurements to Alleviate Potential Spacewalk Requirement

One of the intriguing ways that our Image Science & Analysis Laboratory gathers data from imagery taken in space is to analyze the pictures using 3D measurements. Here, the team used stereo images to create a 3D model of a Node 3 ammonia line installation on the International Space Station. This data was used to show there will be 7-10 inches of positive clearance between this line and an unmanned cargo spacecraft set to resupply the ISS crew later this year. This analysis alleviated concerns that a spacewalk (EVA) would be required to relocate the ammonia lines prior to the arrival of HTV5 resupply ship.
