Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1-2 Operations: Following the JEMAL depressurization, venting, and leak check yesterday, today ExHAM was installed on the JEMAL Slide Table and extended to the JEM Exposed Facility (JEF) side. ExHAM is a cuboid mechanism equipped with a grapple fixture on the upper surface for the Kibo’s robotic arm, Japanese …
3D Printing in Zero-G Experiment Setup: Today, the crew set up the 3D Printer in the Microgravity Science Glovebox (MSG) work volume. The payload ground team remotely operated the device to produce two 3D printed test coupons, and the crew removed and stowed each of them. The 3D Printing In Zero-G experiment demonstrates that a …
Ultrasonic Background Noise Test (UBNT): The crew replaced batteries and transmitted data by closing out the Station Support Computer (SSC’s) Distributed Impact Detection System (DIDS) software and removing the UBNT hardware. UBNT detects high-frequency sounds generated by hardware on the U.S.-built portions of the ISS. Identifying sources of noise will aid in development of a …
Multi-Omics: The crew checked the remaining Fructooligosaccharide (FOS) packages and stowed the Fructooligo Bag for the Japan Aerospace Exploration Agency (JAXA) Multi-Omics investigation. The Multi-Omics analysis of human microbial-metabolic cross-talk in the space ecosystem evaluates the impacts of space environment and prebiotics on astronauts’ immune function by combining the data obtained from the measurements of …
Japanese Experiment Module (JEM) Airlock (JEMAL) Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1-2 Operations: Following the JEM Remote Manipulator System (JEMRMS) Small Fine Arm (SFA) retrieval and detachment of 14 ExHAM #1 samples from the Handhold Experiment Platform last week, today the new samples were installed. ExHAM #1-2 is the first return and sample exchange …
Cygnus Re-entry: Cygnus re-entry burn was completed today at 7:45 AM CDT following unberth last Tuesday, June 14. The NRCSD-E deployment planned for yesterday succeeded in deploying four of five LEMUR satellites. Several additional attempts were made to deploy the final satellite, but were not successful. Orbital-ATK has confirmed via imagery that the deployer’s doors …
NanoRacks CubeSat Deployer- External (NRCSD-E) Operations: Following Cygnus unberth last week, today NRCSD-E conducted post departure satellite deployments prior to Cygnus re-entry tomorrow, June 22. This set of cubesats includes 3 deployment silos containing a total of 5 LEMUR satellites. Two out of three silos (four out of five satellites) were successfully deployed. The Orbital …
Direct Current To Direct Current (DDCU) LA1A Trip: Last Thursday, DDCU LA1A tripped off due to a ~40 amp overcurrent. Parallel DDCU LA4A was already off for Battery 4A conditioning. A Failure Investigation Team (FIT) recommended the crew perform troubleshooting steps including rotation of the rack and visual inspection of the DDCUs, wire harnesses, and …
Autonomous Mission Operations (AMO) Run 3: The crew executed the final of three crew initiated experiment runs by using onboard AMO software to complete the autonomous deactivation and activation of an Expedite the Processing of Experiments to Space Station (EXPRESS) ER7. The AMO investigation tests advanced software and operational concepts to determine how crew members …
Cygnus Spacecraft Fire Experiment-I (Saffire-I) Operations: Yesterday, Saffire-1 successfully completed the first of two phases when a flame experiment was performed inside the Cygnus vehicle after departing the ISS. Today began the second phase which consists of retrieving experiment data via downlink passes at various ground sites. Because fire is extremely dangerous on a spacecraft, …
