ISS Daily Summary Report – 05/07/15

Bone Densitometer (BD) Imaging On-orbit Replacement Unit (ORU) Remove and Replace (R&R): Following a failed checkout of the BD, ground controllers determined that the Imaging Unit had failed. Cristoforetti R&R’ed the unit today in advance of Rodent Research sample collections next Monday. Ground controllers successfully calibrated the unit and are ready to proceed with Rodent Research operations on Monday. Per experiment requirements, ground controllers will perform another calibration within 24 hours of operation.

Binary Colloidal Alloy Test-Low Gravity Phase Kinetics Platform (BCAT-KP) Sample Initiation: Cristoforetti transferred images taken from Sample #5, reset the intervelometer, and initialized Sample #3 for a three week session run. Following this sample, two more samples are planned before all the BCAT-KP samples are initialized and stowed for approximately 6 months while the colloids are left undisturbed to allow for continued growth. The BCAT-KP experiment aims to help materials scientists develop new consumer products with unique properties and longer shelf lives. Colloids are mixtures of small particles distributed throughout a liquid, which include milk, detergents and liquid crystals. Gravity affects how the particles clump together and sink, making the International Space Station an ideal platform to study their fundamental behaviors.

Cell Mechanosensing-3 Thermal Container Reconfiguration: Virts configured the Thermal Container to the Microscope in the Multi-Purpose Small Payload Rack (MSPR) for the Cell Mechanosensing-3 experiment, scheduled for delivery on SpaceX-7. Ground controllers received off-nominal health and status from the Microscope and Thermal containers and are investigating the cause prior to proceeding with the checkout. The investigation identifies gravity sensors in skeletal muscle cells to develop countermeasures to muscle atrophy, a key space health issue. Scientists believe that the lack of mechanical stress from gravity causes tension fluctuations in the plasma membrane of skeletal muscle cells, which changes the expression of key proteins and genes, and allows muscles to atrophy. Muscle cells from rats, and kidney cells from African clawed frogs are tagged with fluorescent gene markers, and attached to an extracellular matrix to study their performance under different tensions, simulating use on earth.

Node 3 (N3) Carbon Dioxide Removal Assembly Bed Remove & Replace (R&R): Today Virts and Kelly completed CDRA reassembly and installed CDRA back into the rack. Tomorrow the crew will complete the maintenance by reconnecting the power/data and fluid lines.

Acoustic Dosimeters: Kelly retrieved 3 acoustic dosimeters that were deployed in various locations throughout the ISS. He downloaded the data for review by ground teams and stowed the dosimeters.

Mobile Servicing System (MSS) Operations: Today, the Robotics Ground Controllers powered up the MSS and reconfigured the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) for translation. Next they translated the Mobile Transporter (MT) from Worksite 2 (WS2) to WS4. Finally the Robotics Ground Controllers maneuvered the SSRMS/SPDM to a park position.
