Bodies In the Space Environment (BISE) Operations Summary Prepared by Amy Jupin Operations Lead EO

2 BISE Mission Objectives Long term: To understand how unusual gravity conditions, and in particular microgravity, affects the perception of self-orientation Specific Objective: Conduct experiments during long-duration microgravity conditions on the International Space Station to better understand how humans first adapt to microgravity and then re- adapt to normal gravity conditions upon return to earth. Subsidiary Objectives: To construct a mathematical model of how visual, body and gravity vector cues are combined in order to explain the effects found above. To use the model developed to: explore the potential value of countermeasures to in- flight, microgravity-related visual illusions (e.g., visual re-orientation illusions); in the development of countermeasures for adverse effects post-flight (particularly after exposure to long-duration microgravity); and as a pre-flight training tool.

3 BISE Overview and Science Ongoing research has developed a unique set of perceptual tests that investigate how humans construct a perceptual 'up direction'. The results obtained on-ground have lead to a weighted vector sum model of the 'perceptual up' It is proposed to utilize these tests to investigate how astronauts' perceptual up adapts from pre-flight to microgravity, and then re-adapts from prolonged microgravity to return to earth-normal conditions. Evaluation of the adaptation to, the effect of and recovery from such long-term exposure to microgravity exposure on perception of orientation will be done by using the Oriented Character Recognition Test (OCHART protocol). There will be a minimum of six subjects to perform BISE onboard ISS.

4 BISE Hardware Overview All hardware is on-board. The items were flown to the ISS as part of the Neurospat experiment. ESA and CSA have an agreement for BISE to borrow their hardware for their operations. The only new item (sent on 15A) will be a NASA provided, flight certified DVD/CD carrying the experiment software. (Not listed below are the A31p power cables, UOP cables and earplugs) NASA A31p Laptop, DVD/CDRW drive and 60GB hard drive (ISS Pantry Items) Multipurpose Bracket and Desktop Plate Neurospat Hardware (crew will assemble for BISE ops) – Light Shield, Frame and Bracket – Control Pad and Bracket

5 BISE Hardware Overview (continued) Light Shield (latches onto frame) Light Shield Frame (slides over laptop screen) Control Pad Bracket (attaches to Light Shield) Control Pad (velcros to bracket) Light Shield Bracket (secures Light Shield position)

6 BISE Experiment Overview The subject will view the laptop screen through a shroud assembled from the Neurospat hardware. On the laptop screen the subject will view a rotated letter superimposed over a highly polarized visual background image presented in different orientations. Subjects will indicate via the Neurospat Control Pad buttons if the shape is recognized as a 'p' or a 'd'. From these judgments, the subjects will determine at what point the 'p'-'d' and 'd'-'p' transitions occur. The experiment will only be conducted in one body-screen orientation as there is no gravity vector on orbit. The experiment itself last about minutes. Over 750 data points are collected during this time. Subjects will perform the OCHART data collection twice on orbit.

7 Planning Constraints In-flight Sessions Session one: FD 10 ± 5 Days Session two: Return -15 ± 10 Days Minimum 60 days between session Sessions should be scheduled prior to any exercise or at a minimum, one hour post-exercise. In-flight Sessions Session 1 FD5 to FD15 Session 2 R -10 +/- 5 days Minimum 60 Days Between Sessions Note: When planning, the Session 1 and 2 dates are the most important scientific constraint; the minimum 60 day separation should be implemented only after the Session 1 and 2 constraints are met.

8 BISE Operations Overview 1. LOCATE EQUIPMENT AND UNSTOW - retrieve Light Shield and A31p from stowage location (Neurospat hardware is currently stowed in the Columbus module) - move to the US Lab; hardware is approved to be set up at O6 location; using current PIP, connect to UOP 2. SETUP - secure laptop on Desktop Plate to Multipurpose Bracket - ghost BISE software onto a harddrive; label harddrive as BISEFLT - attach Light Shield frame, Light Shield, Light Shield bracket, Control Pad bracket, and Control Pad - align screen within tunnel - initiate BISE software 3. DATA COLLECTION - put in earplugs (for noise reduction) - secure head strap; complete the OCHART protocol

9 BISE Operations Overview (continued) 4. SECURE DATA - transfer data from laptop to jumpdrive 5. TEAR DOWN* - remove Light Shield from laptop - remove laptop from Multipurpose Bracket and Desktop Plate 6. STOW* - move to stowage location - stow equipment 7. DOWNLINK DATA - copy data to U:/Payloads/BISE for ground to downlink - when the data is copied, OCA will downlink it and send to OC via IFN. OC will create an OCR marked “medically sensitive” and add the data as a Supporting Attachment. POD will approve it with an action to ptocall0 to copy the file from the Supporting Attachments to their local data storage. *Note: Nominally the crew will tear down and stow all hardware after every BISE session; however, if an A31p is dedicated to BISE, the equipment may be left in a deployed configuration (pending CSA and ESA approval).

10 BISE Operations Notes Subjects will select their subject number at the start of the OCHART protocol; assigned subject numbers will be uplinked in a medically sensitive confidential OCA message. No video is required for the software ghosting. The software load is performed one time only, assuming the hard drive ghosts properly and payloads gets to keep it for the duration of BISE operations. The hardware setup needs realtime video; Experiment ops video requirements are for the first session only for Mike Barrett and Bob Thirsk. Video of other crewmembers, and for Mike/Bob’s subsequent sessions, is desired but not required. For experiment ops, live video is needed for the first ~five minutes so the ground team can verify the subject’s body alignment; subject should have only three touch points with the hardware: the head strap, the right hand on the Control Pad, the left hand on the top of the Light Shield Lab camcorder should be oriented such that we can’t see the subject ID on the screen (private). Per PIRN NA-0001B (BISE Protrusion Exception for Stage 15A and subsequent), the BISE setup is approved only in the LAB1O6 location. Note: All video and scheduling requirements are documented in URC and URC shall supersede any information in this Ops Summary.

11 Power Requirements Voltage Requirement 16 Volts DC through a power converter connected to a 120 volts source Current Requirement 2.6 amp max Power Consumption (Heat Load) 72 watts approximately Power Source Utility Outlet Panel (UOP) (see PIP for most current assignment)

12 Additional Notes BISE hardware was flight certified as part of the Neurospat experiment. It's Flight Safety Data Package (ISS17-NES-KIT-207), accepted by Payload Safety Review Panel, will be used as a reference. Since the Canadian Space Agency has not provided the equipment, it will rely on the Certificate of Compliance/Data Certification/Flight Safety Certificate provided by the European Space Agency for the Neurospat Equipment. The BISE Flight Safety Data Package (submitted by CSA) details changes to the configuration and utilization. The BISE team will be supporting real-time operations from the PTOC in Canada; any Neurospat hardware issues will be worked between BISE and ESA. Screen-shots of the BISE software (as the crew will perform the experiment) are provided on the following slide for your information only.
