Node 3 (N3) Carbon Dioxide Removal Assembly (CDRA) Status: Earlier today ground specialist completed fine leak checks of the N3 CDRA beds. Following the leak checks the N3 CDRA shutdown due to Air Selector Valve (ASV) 104 not reaching commanded position. On Tuesday of this week the crew replaced ASV 106 of this same CDRA. …
Ocular Health (OH): With Cristoforetti assisting as the CMO, Virts completed his Ocular Health ultrasound. Ultrasound scans were performed of his eyes, followed by cardiac echo measurements as part of the Ocular Health data collection. The ultrasound images will be used to identify changes in globe morphology, including flattening of the posterior globe, and document …
Node 3 (N3) Carbon Dioxide Removal Assembly (CDRA) Valve Remove & Replace (R&R): Virts R&Rd the N3 CDRA Air Selector Valve (ASV) 106. The R&R was scheduled due to telemetry indication that showed this valve was taking longer than normal to reach its commanded position, which is consistent with a valve operating under high torque …
Space-X 6 Preparations: Virts and Cristoforetti reviewed capture procedure, proficiency training on the SpX mission profile, rendezvous procedures and crew interfaces for monitoring and commanding the vehicle. The lesson walked through the steps in the rendezvous procedures and provides representative Robotic Workstation (RWS) and PCS screenshots for each step as well as provided an overview …
Gene, Immune and Cellular Responses to Single and Combined Space Flight Conditions-B (TripleLux-B): Today Cristoforetti initiated the first of two TripleLux-B runs. The second run will be scheduled for next week. She placed the thawed Experiment Container (EC) Handling Mechanism (HM) in the BioLab (BLB) rotor and activated the rotor. TripleLux compares the mechanisms of …
Gene, Immune and Cellular Responses to Single and Combined Space Flight Conditions-B (TripleLux-B): Following Monday’s successful recovery of the Columbus Biolab (BLB) facility, Cristoforetti continued with TripleLux-B activities today. She inserted the Experiment Container (EC) Handling Mechanism (HM) into the BLB Glovebox and installed the TripleLux and Viability Test ECs into the left rotor for …
Muscle Atrophy Research & Exercise System (MARES) Functional Checkout: Cristoforetti successfully completed Part 2 of the MARES checkout. She measured, validated, and calibrated different motor profiles of the MARES facility. The MARES hardware consists of an adjustable chair and human restraint system, a pantograph (an articulated arm supporting the chair, used to properly position the …
Node 3 Carbon Dioxide Removal Assembly (CDRA): Overnight the Flight Control Specialist’s attempt to repower Node 3 CDRA failed due to both CDRA bed heaters reporting as failed. The ppCO2 levels remain low and preliminary assessment level will remain below limits with no CDRA for a couple days. The team has been able to override …
Biolab Troubleshooting (TripleLux-B): In order to recover smoke detection in the Biolab facility, Cristoforetti successfully Removed and Replaced (R&R) the smoke detector. She also performed an inspection of the Biolab handling mechanism shutter door. Photos were taken for evaluation by ground teams. Ground teams have performed activation steps and verified that Biolab is go for …
Japanese Experiment Module Airlock (JEMAL) Activation: Virts pressurized and then perform a leak check of the JEMAL. These tasks were performed in advance of operations on March 25 to remove the NanoRacks CubeSat Deployer (NRCSD) and Multi-Purpose Experiment Platform (MPEP)/Small Fine Arm Attachment Mechanism (SAM) from the slide table. Minus Eighty Degree Celsius Laboratory Freezer …
