ISS Daily Summary Report – 7/26/2018

External High Definition Camera (EHDC) Preparation for Return: During the Node 2 Forward External Wireless Communications (EWC) ExtraVehicular Activity (EVA) in June, the degraded Camera Port (CP)3 EHDC was removed for return and refurbishment. To prevent possible exposure to toxic Z-93 paint, the crew executed special procedures today to safely pack the EHDC for return on SpaceX-15. They also stowed the EVA tools that were co-located with the EHDC after checking for potential Z-93 contamination.

Common Berthing Mechanism (CBM) Controller Panel Assembly (CPA) 4 Cable Checkout: Last week, the crew replaced a damaged CBM CPA Latch 4 Actuator Cable. Today the crew re-installed the affected CBM CPA and performed a checkout using this new cable, ensuring proper operation prior to Dragon unberth on 3 August.

Sounded like the crew, Alex in particular, spent time assembling a special containment fence in Dragon to support/contain the rather large and heavy Latching End Effector returning on this flight. Cargo already installed complicated his efforts and delayed completion until tomorrow.

ISS Daily Summary Report – 8/01/2018

Dragon Cargo Operations: Today the crew finished the last tasks on SpaceX-15 Cargo Message #4, including installation of the LEE Fence Hardware, as they continued to pack and load items slated for return on Dragon. Today’s activities were required before the tomorrow’s activity to install the degraded Space Station Remote Manipulator System (SSRMS) Latching End Effector (LEE) in Dragon. Current weather forecasts are a GO for Dragon departure on 3 August.

Mobile Servicing System (MSS) Operations: Yesterday and overnight, the Robotics Ground Controllers walked the Space Station Remote Manipulator System (SSRMS) off onto Mobile Base System (MBS) Power Data Grapple Fixture (PDGF) 3. The SSRMS was then maneuvered as required to perform the Latching End Effector B (LEE-B) Snare Cables survey before a walk-off from MBS PDGF3 to N2 allowed for controllers to grapple the Dragon vehicle in preparation for Friday’s release.

The International Space Station Partners and mission managers polled “go” for tomorrow’s release of the SpaceX Dragon cargo craft for its deorbit and splashdown in the Pacific Ocean to wrap up the CRS-15 mission.

With favorable weather conditions forecast in the splashdown zone, Dragon’s hatch will be closed early Friday around 3 a.m. Central time. Robotic ground controllers will then use the Canadarm2 robotic arm to detach Dragon from the Earth-facing port of the Harmony module around 5:30 a.m. Central time and will maneuver Dragon into the release position.

With Expedition 56 Flight Engineer Serena Auñón-Chancellor of NASA monitoring Dragon’s systems, the ground controllers will release Dragon from Canadarm2 at 11:37 a.m. Central time. After its release, Dragon will conduct a series of “departure” burns to move to a safe distance away from the station.

Several hours later, at 4:23 p.m. Central time, SpaceX flight controllers at Hawthorne, California will command Dragon’s engine to fire for 12 minutes and 53 seconds in the deorbit burn that will enable Dragon to slip out of orbit for its descent back to Earth.

Dragon’s parachute-assisted splashdown is scheduled at 5:17 p.m. Central time, 3:17 p.m. Pacific time, about 410 miles southwest of Long Beach, California. It will take about two days for Dragon to be brought back to port for its cache of cargo and scientific experiments to be unloaded.

ISS Daily Summary Report – 8/02/2018

Double Coldbag Packing: As part of the final Dragon packing operations, the crew packed time sensitive cold storage science items. The crew must pack these items late in the Dragon packing operations to minimize the amount of time the science samples are out of refrigeration prior to being delivered to the investigation teams on the ground.

Dragon Cargo Operations: Today the crew completed the last of the SpaceX-15 cargo transfer operations as they packed and loaded the final items slated for return on Dragon. As part of today’s cargo activities the crew ingressed the Bigelow Expandable Aerospace Module (BEAM) module to retrieve the degraded Space Station Remote Manipulator System (SSRMS) Latching End Effector (LEE) S/N 202 and packed it for return. While the crew had the hatch open to the BEAM module, they stowed the Treadmill Subject Loading System (SLS) into the BEAM.

Dragon Ends Stay at Station, On Its Way Home

Robotic flight controllers released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm at 12:38 p.m. EDT, and Expedition 56 Serena Auñon-Chancellor of NASA is monitoring its departure.

Dragon’s thrusters will be fired to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn about 5:23 p.m. The capsule will splashdown about 6:17 p.m. in the Pacific Ocean, where the SpaceX recovery team will retrieve the capsule and its more than 3,800 pounds of cargo, including a variety of technological and biological studies.

NASA and the Center for the Advancement of Science in Space (CASIS), the non-profit organization that manages research aboard the U.S. National Laboratory portion of the space station, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours of splashdown.

Dragon is the only space station resupply spacecraft currently capable of returning cargo to Earth, and this was the second trip to the orbiting laboratory for this spacecraft. SpaceX launched its 15th NASA-contracted commercial resupply mission to the station June 29 from Space Launch Complex 40 from Cape Canaveral Air Force Station in Florida on a Falcon 9 rocket that also previously launched NASA’s TESS mission to study exoplanets.

Out of curiosity, is the blackening due to reentry heat or is it deposit ablative heat shield material?

Deposit of ablative heat shield material mostly. But the deposit "burns" into the SPAM (backshell TPS material) somewhat. A pressure wash only partially removes the deposit.
The SPAM itself only turns slightly yellowish/brownish during reentry.

From: NASA’s Management of Crew Transportation to the International Space Station
(NASA Office of Inspector General · November 14, 2019)

Quote from: NASA’s Management of Crew Transportation to the International Space Station, Page 11

In August 2018, SpaceX experienced failures on two main parachute canopies during the return of its Dragon capsule from a cargo resupply mission to the ISS. This resulted in additional work to improve load balancing on the planned crewed parachute system. However, the parachute design for SpaceX cargo missions uses three instead of four parachutes and receives more turbulence from the cargo capsule compared to a crew capsule and therefore they are not suitable for direct comparison to one another.

Please pardon the bump, but if we have any more information about these CRS-15 parachute failures, it should be linked from this thread.
