ISU Brief
Established in 1988 with 1 st session at MIT
International, Interdisciplinary, Intercultural
Offers 2 distinct programs
Space Studies Program (SSP)
9-week comprehensive space course in a different location every summer NASA Ames (09), Barcelona (08), Beijing (07)
Masters of Science in Space Science/Space Management (M.Sc)
12-month M.Sc program based in Strasbourg, France with 3-month internship in space industry

Origins of Iris
Spring 2008 – Canadian Astronaut Dr. Robert Thirsk expressed interest in a student experiment on his long duration ISS mission (Expedition 20 & 21)
Approached International Space University for its International, Interdisciplinary, Intercultural approach to space activities
Goals:
Aid student understanding of processes & procedures required to place human-rated payload into orbit
Develop platform for future ISS-related academic projects
Gather useable data to aid long duration spaceflight research

Experiment Set-up
Iris – Image Reversal In Space – is a neurovestibular experiment designed to test effect of microgravity on human perception of optical illusions
Ambiguous figures – a figure in which the brain sees 2 distinct images – are used to determine the time required for brain to realize each image.
10 figures – 1 minute each
Powerpoint DVD
Hypothesis – time lag between each image will increase in microgravity

Experiment Set-up
Neurovestibular physiology includes otholith organs of the inner-ear responsible for body’s tilt
In microgravity, otholiths become confused with other sensory preceptors to determine body’s orientation

Testing, Verification & Certification 10/14/09 Iris - Image Reversal In Space - IAC'09 Iris Mission Timelines, Crew Training Plans, Crew Operations Procedures, Software Developed July 2008 – ISU Expedition 20 Mission Briefings Fall 2008 – CSA Payload Safety documentation, Ex & Ops finalized, ISS Payload Directorate Approval Winter 2008/2009 – CSA/NASA Iris Crew Training Ops Reviewed Pre-flight data March 2009 – NASA Flight Readiness Reviews (FRR) May 2009 – NASA Iris Payload loaded on Shuttle Endeavour & STS-127 June 2009 – NASA

Ground Based Studies
ISU Study
Following Iris crew procedures with ISU Masters 2009 class
ESA 50th Parabolic Flight Campaign
Simulated weightlessness trials
Most realistic comparison to in-orbit trials
AsMA Study
Unique test of supine (inverted) position

ISS Trials & Support Operations
Soyuz TMA-15 May 27 2009
STS-127 Launch July 15 th 2009
Two in-flight sessions
FD+40 (July 10 2009)
FD R-40 (September 17 2009)
ISU Ex-Ops support via NASA ARC

Preliminary Findings 10/14/09 Iris - Image Reversal In Space - IAC'09

Future Steps 10/14/09 Iris - Image Reversal In Space - IAC'09 Ground Based Studies On-going 2009 – ISU Iris In-flight Sessions #1 Iris In-flight Session #2 Crew Debrief Summer / Fall 2009 – ISU/CSA/NASA Data Analysis Publications Closeout Winter 2009 / Spring 2010 – ISU Next ISS Academic Experiment Kick-off Summer 2010+ - ??

Thank You
This opportunity would not be possible without the dedication and resilience of 100+ individuals across ISU, CSA, NASA & ESA
Special thanks to Dr. Robert Thirsk & Dr. Gilles Clement for sharing their vision and expertise
