Main Bus Switching Unit (MBSU) 3 Status: Following yesterday’s MBSU 3 failure, troubleshooting was not successful and the Flight Investigation Team (FIT) determined MBSU 3 is failed. The crew and ground teams coordinated the install of the Node 1 Y-Jumper and Node 1 Contingency Power Jumper and removal of the Node 1 Channel 2 and …
Main Bus Switching Unit (MBSU) 3 Failure: This morning, a critical bus loss occurred on MBSU 3 that brought down loads on channels 3A and 3B. Major impacts included KU-band, Alpha Magnetic Spectrometer (AMS), Control Moment Gyro (CMG)-3 and Space Station Remote Manipulator System (SSRMS) redundancy. Troubleshooting was not successful and teams are assessing the …
SpX-17 Launch Status: SpX-17 is now scheduled to launch on Wednesday, May 1 with capture/berthing on Saturday, May 4. Rodent Research-12 (RR-12): The crew restocked all four Rodent Habitats by adding new food bars, and cleaning the interior lid and camera lenses. The access unit was also cleaned. Rodent Research-12, Tetanus Antibody Response by B …
MISSE-FF (Materials ISS Experiment Flight Facility): Robotics Flight Controllers successfully installed one of the new MISSE Science Carrier (MSC) in the #1 position of the MISSE-FF facility and verified commanding capability. Robotics will continue to install the remaining 3 MSCs that arrived on NG-11. The primary Materials ISS Experiment Flight Facility (MISSE-FF) platform provides the …
Kubik: The crew installed Kubik #5 and #6 in the Columbus module in support of the upcoming NanoAntioxidents experiment arriving on SpX-17. Kubik is a small controlled-temperature incubator or cooler with removable inserts designed for self-contained, automatic microgravity experiments such as those using seeds, cells, and small animals. International Commercial Experiment Cubes (ICE Cubes): The …
Solidification Using Baffles in Sealed Ampoules SUBSA): The crew de-installed the SUBSA hardware facility from the Microgravity Science Glovebox (MSG) work volume. The objective of the SUBSA investigation is to advance understanding of the processes involved in semiconductor crystal growth. It offers a gradient freeze furnace for materials science investigations that can reach 850°C. Samples …
Treadmill 2 (T2) Mechanical Issues and False Fire: During a T2 session this morning, the crew reported that the belt slowed dramatically, a grinding noise was heard, and the T2 Smoke Detector triggered a fire alarm. Air measurements confirmed this to be a false fire event and investigation by the crew confirmed that the T2 …
Medical Proteomics: The crew performed a blood draw session in support of the JAXA Medical Proteomics experiment. Medical Proteomics evaluates changes of proteins in blood serum, bone and skeletal muscles after space flight, and supports identification of osteopenia-related proteins. By combining research results for space mice, astronauts and ground patients, proteins related to osteopenia can …
Crew Half Duty Day: Today was a half duty day for the crew. Following Cygnus berth tomorrow, they will work Saturday to transfer cargo from Cygnus to the ISS. Fluids Integrated Rack (FIR)/Light Microscopy Module (LMM)/Biophysics-6 experiment start: As a followup to the discovery of the plate with damaged sample capillary(s) on Monday, today the …
Northrop Grumman 11 (NG-11) Launch/Berth: NG-11 launched successfully today at 3:46 PM CT from NASA’s Wallops Flight Facility in Virginia. Over the next two days, S.S. Rodger Chaffee will perform a series of phasing burns to rendezvous with ISS. Vehicle capture is planned for Friday, April 19, at 4:30 AM CT. JEMAL (JEM Airlock) Configuration: …
