External Thermal Control System (ETCS) Loop B Recovery Status: Ground teams continue working towards incrementally re-pressurizing ETCS Loop B. Last night’s re-pressurization resulted in a 1% decrease in Ammonia Tank Assembly (ATA) tank quantity. Ground teams are targeting a total of 7% decrease (0.63 c.f. NH3) before a Loop B restart is attempted. The Loop …
External Thermal Control System (ETCS) Loop B Recovery Status: Ground teams are methodically working towards repressurizing and recovering ETCS Loop B and the systems which were deactivated as a result of yesterday’s safeing response. The Loop B Interface Heat Exchangers (IFHX) are still bypassed and isolated, preventing internal heat rejection on Loop B. Due to …
Ammonia Leak False Alarm: This morning at 3:58am CST, ISS telemetry indicated a possible leak of ammonia within Node 2 in the US Segment. The crew performed emergency procedures and subsequently evacuated the US Segment and isolated themselves to the Russian Segment. The External Thermal Control System (ETCS) Loop B, Node 2 Low Temperature Loop …
SpaceX-5 Dragon Ingress and Cargo Ops: The crew started their day by opening the Dragon hatch, obtaining an air sample, and installing Inter-module Ventilation (IMV) ducting. They then began cargo operations by removing the items located in the vehicle’s center stack. ARED Right Upper Stop Cable Severed: Over the weekend, the crew reported that the …
SpaceX-5 Dragon Status: On Saturday January 10th, SpaceX-5 successfully launched from Cape Canaveral at 3:47am CST. After a nominal rendezvous with ISS, the ISS Crew successfully captured the spacecraft today at 4:54am CST utilizing the Space Station Remote Manipulator System (SSRMS). Robotics Ground Controllers then used the SSRMS to support the inspection of the Dragon …
Capillary Flow Experiments-2 (CFE-2): Virts reviewed CFE Vane Gap test operations and crew procedures. He then completed the setup, which includes retrieving CFE hardware, preparing the Maintenance Work Area (MWA) work surface only, securing the CFE hardware on the MWA, and positioning the HD Camcorder. He prepared a CFE-2 Vane Gap vessel for testing by …
SpaceX-5 Status: Yesterday, SpaceX announced they needed additional time to work the actuator problem and officially moved the next launch attempt to Saturday, January 10th at 3:47am CST with berthing taking place on Monday, January 12th. As a result of the slip, SpaceX unberth will move to February 10th. A delta Launch Readiness Review is …
SpaceX-5 Launch Aborted: SpaceX-5 launch was aborted shortly before liftoff this morning, after ground teams observed an unexpected telemetry indication associated with an upper stage actuator. The next launch attempt is scheduled for Friday, January 9th at 4:08am CST. Dragon will deliver more than 5,000 pounds of food, supplies and science experiments to ISS. Binary …
Haptics-1: Wilmore set up Haptics-1 equipment on rack front seat tracks in the Columbus for the execution of experiment protocols in a Vest (body mount) configuration. He then performed the seven Haptics-1 experiment protocols and transfered data to an SSC for downlink. The objective of the Haptics-1 experiment is to execute an in-orbit engineering parameter …
Space Dynamically Responding Ultrasonic Matrix System (SpaceDRUMS): Virts and Cristoforetti had difficulty with a leaking Quick Disconnect (QD) during removal of SpaceDRUMS hardware for return on the SpaceX-5 vehicle. Completion of this task has been postponed while the Ground team develops procedures to address the issue and allow removal of the hardware. The crewmembers removed …
