Iris - Image Reversal In Space - ISU International Space Station Experiment


Published on

The Image Reversal In Space Experiment was a product of 50+ students of the International Space University's Academic Programs and the first of its kind on the ISS. Dr. Robert Thirsk used the experiment on the International Space Station during Expedition 20 & 21. Presentation made at 60th International Astronautical Congress, Daejeon, Republic of Korea, October 2009 by Tahir Merali.

  • The Iris Experiment shows a set of 10 ambiguous figures for 1 minute each. Data is collected via keystroke when the flipping or “precept reversal” occurs and is saved to file.
  • Space payloads – especially human rated – are required to pass scrutinizing performance tests A single DVD pre-loaded with Windows settings and Iris would be run on one of the 53 laptops in the US, JAXA or ESA Modules
  • After numerous delays STS-127 launched into orbit on July 15 th 2009 with the Iris DVD payload, As a result of the delays, redundancy operations were taken to load the software via telemetry. After the arrival of the payload, nominal operations resumed for the 2 nd trial. Student involvement in operations support, data analysis and report preparation
  • Ground Based Studies Complete / In-flight sessions complete / Data Analysis_Publications_Closeout by ISU The platform for a simple experiment has been a success and launches the possibility for future experiments… (30 seconds)
