Lab Carbon Dioxide Removal Assembly (CDRA) Troubleshooting: On Monday, Remote Power Controller Module (RPCM) LAD62B_A RPC 12 experienced a trip. This RPC powers six selector valves internal to the Lab CDRA. Today, troubleshooting was performed with Mastracchio accessing the Atmosphere Revitalization (AR) rack through the Trace Contaminant Control System (TCCS) opening. He inspected and verified …
Conjunction with Object #35758 Status: Ground teams received updated tracking data for a possible conjunction with Object #35758. The conjunction is of high concern and ground controllers will be tracking it throughout the evening. If a debris avoidance maneuver is needed, a Pre-Determined Debris Avoidance Maneuver (PDAM) would be executed at approximately 3:42pm CDT on …
Urine Processing Assembly (UPA) Advance Recycle Filter Tank Assembly (ARFTA) Change Out and Shock: Commander (CDR) Wakata and Flight Enginer (FE)-3 Swanson removed ARFTA serial number (S/N) 1 and installed S/N 2. Swanson then started a series of activities to shock ARFTA S/N 2 using pretreated water from the Waste and Hygiene Compartment (WHC). The …
X2R12.1 Software Transition: Today the ground team completed the X2R12.1 software update that was started on Saturday. All activities were successfully performed and the system is back in nominal configuration. The X2R12.1 software update provides enhancements to the following Multiplexer/Demultiplexer (MDM)s: External (EXT), Internal (INT), Payload (PL), Lab (LA)-3, Starboard Thermal Radiator (STR), Port Thermal …
38 Soyuz (38S) Dock: 38S completed a thirty-four orbit rendezvous with successful docking to the Mini-Research Module (MRM)-2 port of the ISS at 6:53pm CDT. The addition of Soyuz crewmembers Skortsov, Artemyev, and Swanson returns the ISS to a full 6-crew complement. Following hatch opening, the entire crew participated in a welcome ceremony and later …
38 Soyuz (38S) Status: 38S is performing nominally following launch yesterday afternoon. 38S was originally planned to dock to the ISS to last night following a 4-orbit rendezvous plan. The Soyuz was unable to perform the DV3 burn at the planned time and the 4-orbit rendezvous was down-moded to a 34-orbit rendezvous. Tracking of 38S …
38 Soyuz (38S) Launch: Soyuz Commander Skortsov, Artemyev, and Swanson launched onboard Soyuz 38S this afternoon at 4:17pm CDT. Ascent was nominal, but the subsequent DV3 burn was not performed as planned and today’s docking was postponed. Docking is now planned for Thursday evening at 6:58pm CDT. The vehicle is in a stable configuration and …
Japanese Experiment Pressurized Module Inter Module Ventilation (IMV) Cleaning: Commander (CDR) Wakata temporarily removed the Starboard Forward Fan and IMV grills and cleaned behind them. Wakata and and Flight Engineer (FE) Mastracchio then measured the air velocity in the JEM using the Velocicalc instrument. Ice Crystal-2 Troubleshooting: During an Ice Crystal-2 experiment run on March …
Conjunction with Object #27391 Status: The Pre-Determined Debris Avoidance Maneuver (PDAM) that was tentatively planned due to this high concern conjunction was cancelled. Ground teams tracked the object closely and determined that the probability of collision with the object had dropped significantly enough that the PDAM maneuver was not required. Time of closest approach has …
