An experiment was performed, on Sept. 7, 2001, aboard the International Space Station (ISS) to video tape the U.S. Lab’s condensate venting event with cameras located on the Space Station Remote Manipulator System (SSRMS). Images of the vent plume were acquired close to both the port and starboard vent nozzles. The imaging started with a wider view and then zoomed in before the shutdown phase of the vent event occurred. The data from the video images was analyzed previously to obtain the characteristics of the vent including the duration of the vent event, the approximate cone angle encompassing the core of the vent plume, the number of particles outside the core plume, and the velocities of the ice particles. The data from this experiment has been used to develop an update for the model of the U.S. Lab condensate vent plume. This paper will discuss that update to the model. The condensate vent model can be used to assess the impact of the vent onto other ISS hardware. |
