SpaceX (SpX)-17 Launch: Today’s planned SpX-17 launch was scrubbed due to an issue with the recovery drone ship. There will be another launch attempt tomorrow at 1:48 AM CT with a corresponding planned arrival to ISS on Monday, May 5 at 6:00 AM CT. Rodent Research-12 (RR-12): The crew restocked Rodent Habitats 3 and 4 …
Veggie PONDS Validation: The crew completed a reservoir fill on the Veggie Ponds facility. Organisms grow differently in space, from single-celled bacteria to plants and humans. Future long-duration space missions will require crewmembers to grow their own food. Understanding how plants respond to microgravity and demonstrating the reliable vegetable production on orbit are important steps …
Crew Off-Duty: The crew was off-duty today in preparation for SpaceX (SpX)-17 arrival scheduled on Sunday at 6:00 AM CT. SpX-17 launch is scheduled for Friday, May 3 at 2:11 AM CT. Main Bus Switching Unit (MBSU) Status: Following Monday’s MBSU 3 failure, team discussions led to the recommendation to Remove & Replace (R&R) the …
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 …
