NASA ISS On-Orbit Status 20 May 2015.

The Expedition 43 crew completed preparations on Wednesday to send SpaceX’s Dragon cargo vehicle back to Earth.
NASA astronauts Scott Kelly and Terry Virts transferred samples from two of the station’s Minus Eighty Degree Celsius Laboratory Freezer for ISS, or MELFI, freezers for return on Dragon. These included samples from the Cell Shape and Expression, CASIS PCG-3, Nematode Muscles experiments along with human research samples.

After final cargo loading was completed, the crew closed the hatch to Dragon and began preparing it for release tomorrow. Dragon has been grappled by the station’s robotic arm and is set to be released on Thursday, May 21 at 7:04 a.m. EDT.

On-Orbit Status Report

Double Cold Bag (DCB) Packing: Virts and Kelly packed the +4 degrees Celsius (°C) DCB with conditioned Ice Bricks and samples from Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI)-2 and -32°C DCBs with Ice Bricks and frozen samples from MELFI-3. The +4°C DCB will be returning with Cell Shape and Expression, CASIS PCG-3, Nematode Muscles, and NanoRacks Module-53 samples. The -32°C DCB will be returning with frozen HRP samples. Once packed, the DCBs were placed in Dragon prior to hatch closure.

SpaceX-6 Departure Preparations: This morning, the crew completed final cargo loading. Later, they configured Dragon’s pressurized segment for departure and closed its hatch. Once the Dragon hatch was closed, they configured the Node 2 vestibule by removing Air Revitalization System (ARS) and data jumpers then installed the Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs). SpaceX-6 unberth activities are scheduled to start this evening at 11:30pm CDT and Dragon release at ~6:04am CDT Thursday morning utilizing the Space Station Remote Manipulator System (SSRMS).

Node 3 Forward 2 Stowage Removal: In preparation for Permanent Multipurpose Module (PMM) relocation next week, Virts removed stowage from the Node 3 Forward location. PMM relocation from Node 1 nadir to Node 3 forward is planned for Wednesday, May 27th.
