Extravehicular Mobility Unit Loop Scrub: Today, the crew configured Extravehicular Mobility Unit (EMU) suits 3003 and 3008 for loop scrubbing. Once the scrubbing activity was complete, they reconfigured hardware and performed iodination of Ion Filters for both suits. A sample of the water was obtained after the loop scrub activity to determine the effectiveness of …
Although communication between those at home and those on a ship has improved over the decades, being in mid-ocean still has quite a few communication challenges.
Lighting Effects: A 51S crewmember conducted a Visual Performance Test by stowing the hardware in their crew quarters, setting the light to the correct mode, turning all other light sources in the crew quarters off, and performing a Numerical Verification Test and a Color Discrimination Test. The completed tests were photographed and downlinked. The Lighting …

After a trio of spacewalks this month, including the final one conducted last Friday by Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA, the Expedition 53 crew returned to a schedule of full-time science this week.

The primary job of the SPURS chief scientist is akin to conducting a symphony orchestra of oceanographic measurements.

Engineers lifted and installed a third umbilical on the mobile launcher at NASA’s Kennedy Space Center in Florida for a fit check. The tower on the mobile launcher will be equipped with several connections or launch umbilicals like this one. After the fit check was completed, the umbilical was lowered down and will be installed …
USOS Extra Vehicular Activity (EVA) #46: Randy Bresnik (as EV1) and Joe Acaba (as EV2) successfully performed US EVA #46 with a Phased Elapsed Time (PET) of 6 hrs 49 min. The primary goals of the EVA were to Remove and Replace (R&R) a fuse in the Special Purpose Dexterous Manipulator (SPDM) Enhanced ORU Temporary …
