2HRP Concerns – Centrifuge Ops
• After reviewing cabin video from a previous MARES 
commissioning activity, HRP came to the conclusion that 
scheduling centrifuge operations while MARES is deployed 
should be avoided  
• There is insufficient room to perform the blood draw in the endcone of 
COL while MARES is deployed and access to the centrifuge for sample 
loading and unloading is restricted.  Crew could potentially still load and 
unload samples, but it would be an awkward process since a 
crewmember cannot float directly in front of the centrifuge with the door 
open while MARES is deployed.  This would most likely violate our vein to 
MELFI constraint.
• FD5-12 Sarcolab-3 ops is within the window of Kimbrough’s FD60 Biochem
Profile/Repository session as well as Pesquet’s FD15 session and Whitson’s 
FD15 Biochem Profile/Cardio Ox/Repository session
3HRP Concerns – USND Ops
• Non-Sarcolab-3 Ultrasound scanning would be impacted by 
MARES deployment  
• The crew scans in front of the HRF Racks and there would be insufficient 
room.  FD5-12 Sarcolab-3 ops is within the window of Whitson’s FD15 
Cardio Ox session
• R-10 +/-8 Sarcolab-3 ops (in Inc 51) would carry the same impacts as 
above for Pesquet and Whitson’s R-14 Biochem Profile, Cardio Ox and 
Repository sessions
• FD45 +/-15 Sarcolab-3 ops is the exact same window as Fluid Shifts for 
Pesquet, Whitson and Novitsky
• HRP recommends that the Dilution Measures (because of the blood draw 
and centrifuge) and Baseline Imaging Measures (Ultrasound scanning in front 
of HRF Racks) should be performed without MARES deployed.  
• From an HRP perspective, Chibis ops could be planned in the same 
timeframe as Sarcolab-3 because both Ultrasound units can be used.  
4HRP Concerns – HRF PC Ops
• Access to our HRF PCs 1 and 3 would be restricted and 
probably impossible during MARES deployment 
• PC1 is required to downlink Ultrasound data (other than the Sarcolab
Ultrasound data which will use our HRF PC2 on HRF Rack 2), so could 
delay downlink of Fluid Shifts Chibis Ultrasound data.  
• PC3 supports the Lighting Effects experiment, so could not be scheduled 
at the same time.  Lighting Effects does not have specific flight days, so 
planning can accommodate that potential conflict.
• In general, most of HRF Rack 1 cannot be accessed during 
MARES deployment 
• It would have to be worked during WLP planning to retrieve and temp 
stow anything needed for HRP experiment ops during MARES 
deployment
549/50 Gr&C Constraints
• Execute Planning Gr&C 5.2.15 discusses MARES constraints with HRF
• Rule: Operations on HRF1 and HRF2 front racks and STBD cross panel shall not 
be scheduled when MARES is temporary stowed in bay 4 
• Rationale: When MARES is temporary stowed in bay 4 to allow maintenance 
operations in bay 3, reduced crew work envelope for accessing HRF1, HRF2 and 
STBD cross panel items has been detected. 
• Rule: When MARES is in its deployed configuration, use of SLAMMD 
calibration should not be scheduled 
• Rationale: Interference has been detected between the HRF1 SLAMMD left side 
calibration work envelope and the on orbit protrusion (right side) when MARES is 
installed in F3 in stowage configuration. 
• Rule: When MARES is deployed in Bay 3, crew tended operations on HRF2 
and EPM shall not be scheduled concurrently to MARES crew tended 
operations 
• Rationale: Despite of no Interference is detected between HRF2 work volume in 
A4 and MARES when deployed in bay 3, a corridor in bay 4 AFT side shall be 
maintained for guarantee the emergency egress when MARES is in deployed 
configuration in bay 3. 
6Next steps
• Does ESA have any data/analysis to show any possible 
interference?
• Does ESA have any input from the last crew to use MARES on access 
issues?
• POIC planners will work to de-conflict Sarcolab-3/MARES ops 
from other HRF rack use but a priority call may be needed if this 
is not possible
• Prelim OOS TIM was able to de-conflict these ops fairly well
• POIC would like to propose a splinter at the next POIWG in July 
so HRP and ESA can discuss these issues.  If ESA can bring any 
analysis they have to that discussion that would be very helpful.
