Space Station Status Report for June 28

All ISS systems continue to function nominally, except those noted previously or below. Underway: Week 4 of Increment 24

For today's Soyuz 23S relocation and Progress 38P docking (7/2), crew sleep cycle was shifted to the right: Wake-up – 5:30am (from 2:00am), sleep – 10:30pm (from 5:30pm) EDT. Tomorrow's wake/sleep: 7:00am – 10:30pm, until 7/3.

Soyuz TMA-19 (23S) relocation was completed without incident, although delayed by 75 min due to a stall of the 4B BGA (Beta Gimbal Assembly) motor as it was moving the 4B solar array to its latched position. After system recovery by ground control, it took the array some time to reach its final position, delaying the undocking from 1:58pm to ~3:13pm. It freed up the SM (Service Module) aft port for the arrival of Progress 38P on 7/2 (aft port being more advantageous for using Progress for reboost/debris avoidance maneuvers). After a brief ride in their crew return vehicle, FE-5 Yurchikhin, FE-4 Wheelock & FE-6 Walker docked at the MRM1 Rassvet module (at FGB nadir) at 3:38pm EDT, completing the spacecraft's relocation in about 25 minutes. [After undocking, Soyuz CDR Yurchikhin backed away from the station 25-30 m at ~0.12 m/s, then translated the spacecraft below the station, slewing sidewise through 90 deg along the ISS toward the aft end before rotating ("indexing") the Soyuz around its longitudinal axis to align its periscope with the docking target on the MRM1 (Mini Research Module 1), spending a short time in station-keeping mode. Final approach began at ~3:34pm, with docking at ~3:38pm. After hooks and latches were engaged, the crew conducts transfer hatch & vestibule leak checks, opens Soyuz & MRM1 transfer hatches and then re-enters the station through the MRM1/FGB. The relocation was conducted with ISS entirely in "earth-fixed" LVLH (local vertical/local horizontal) attitude, without the usual Inertial snap/hold.]

Before hatch closing & leak checking (~9:40am), Yurchikhin configured and checked out communications from 23S (~8:03am-8:19am), while the ground deactivated the LKT (Local Temperature Sensor) on Soyuz and the SKV-1 air conditioner on ISS.…
