NASA Space Station On-Orbit Status 19 August, 2020 – Space Science and Lab Maintenance

The HTV-9 would later be uninstalled from Harmony before being released it into Earth orbit that day completing an 85-day cargo mission. Credit: NASA.

The Expedition 63 crew has turned its attention toward space science and lab maintenance after releasing a Japanese cargo craft from the International Space Station on Tuesday.
More cargo and crew missions to replenish the orbiting lab are planned for October.

Commander Chris Cassidy switched off communications gear today used to send commands to Japan’s H-II Transfer Vehicle-9 (HTV-9) after its departure on Tuesday. The HTV-9 will orbit Earth until Thursday morning when it descends into the atmosphere for a fiery, but safe demise over the South Pacific.

The NASA commander spent the rest of the day working on orbital plumbing and life support gear. Cassidy removed and replaced the Waste and Hygiene Compartment’s recycle tank located in the Tranquility module. He also inspected out gear that analyzes organic compounds in the station’s air.

Veteran station cosmonaut Anatoly Ivanishin focused on battery work as he installed current converters throughout the lab’s Russian segment. First-time cosmonaut Ivan Vagner spent Wednesday morning working on more orbital plumbing before exploring ways to improve Earth photography techniques and determine how mission events impact the orbiting lab.

Space traffic will be clear at the space station for the rest of August and into September. The mission pace will pick back up in October with a U.S. Cygnus cargo ship from Northrop Grumman, the Expedition 64 crew and the SpaceX Crew-1 mission all to set to arrive within a period of three weeks.

On-Orbit Status Report


Multi-Purpose Experiment Platform (MPEP): The crew removed the Handhold Experiment Platform adapter from the MPEP and then removed the MPEP from the JEM Airlock slide table. Multi-Purpose Experiment Platform provides the structural backbone for deployers when being transferred to the outside via the Kibo airlock and grasped by the JRMS robotic arm.

ISS HAM: The crew initiated a HAM contact with Kopernik Observatory & Science Center in Vestal, NY. ISS Ham Radio provides opportunities to engage and educate students, teachers, parents and other members of the community in science, technology, engineering and math by providing a means to communicate between astronauts and the ground HAM radio units.


Total Organic Carbon Analyzer (TOCA) Preventative Maintenance: Today, the crew installed the spare TOCA in the LAB to perform a functional checkout. The crew also installed a new Waste Water Bag (WWB) and Buffer Container Packet. The buffer container from the prime TOCA was moved to the backup TOCA, and a new buffer container was installed into the prime TOCA. The checkout is performed every two years to ensure functionality of the TOCA in the event of a failure with the prime unit. The buffer container is also replaced every 47 samples or two years. The crew confirmed there was no evidence of a leak in the spare TOCA.

Regenerative Environmental Control and Life Support System (ECLSS) Recycle Tank Remove and Replace (R&R): Today, the crew performed a changeout of the Regenerative ECLSS recycle tank as part of routine operations. Recycle tanks are reusable bladders that hold resultant brine following waste processing from the Urine Processing Assembly (UPA). The recycle tank is replaced every six months as part of preventive maintenance to ensure continued performance and preclude a functional failure.
