NASA Space Station On-Orbit Status 20 September 2018 - Service Module ISS Reboost

The launch of a Japanese resupply ship to the International Space Station was postponed till Saturday. Meanwhile, the Expedition 56 crew moved on with critical space research and orbital lab maintenance.

Inclement weather at the Tanegashima Space Center in Japan led managers at JAXA (Japan Aerospace Exploration Agency) to postpone the launch of its HTV-7 resupply ship by one day. The HTV-7 is now due to launch atop the H-IIB rocket Saturday at 1:52 p.m. EDT loaded with over five tons of cargo, including new science experiments and science hardware. Its arrival at the station is now planned for Thursday at 7:54 a.m.

The station's Zvezda service module fired its engines today slightly boosting the space lab's orbit. The reboost enables a crew swap taking place next month when Expedition 57 begins. Three Expedition 56 crew members will depart on Oct. 4 and return to Earth inside the Soyuz MS-08 spacecraft. A new pair of Expedition 57 crew members will arrive aboard the Soyuz MS-10 crew ship to replace them Oct. 11

Astronauts Ricky Arnold and Serena Auñón-Chancellor conducted a variety of biomedical research today sponsored by scientists from around the world. The duo partnered up for ultrasound scans inside Europe's Columbus lab module as doctors on the ground monitored in real-time. Arnold also worked throughout the day processing blood and urine samples inside the Human Research Facility's centrifuge.

The biological sample work is supporting a pair of ongoing experiments observing the physiological changes to humans in space. The Repository study analyzes blood and urine samples collected from astronauts before, during and after a space mission. The Biochemical Profile study also researches these samples for markers of astronaut health.

Commander Drew Feustel and Fight Engineer Alexander Gerst worked throughout the orbital lab on housekeeping tasks. Fuestel was in the Unity module installing computer network gear on an EXPRESS rack that can support multiple science experiments. Gerst relocated smoke detectors in the Tranquility module then moved on to computer maintenance in the Destiny lab module.

On-Orbit Status Report

Service Module (SM) ISS Reboost: This afternoon at 1:05 PM CT, the ISS completed a 17s reboost using the SM main engine. This reboost is the final reboost in a series of three burns to set up proper phasing for 54S landing on October 4th and 56S launch, which will use the 4-orbit rendezvous profile, on October 11th. ISS velocity increased by 0.27 meters per second (m/s) and the height of the ISS orbit increased by 0.49 kilometers (km).

Express Rack 2: The crew removed the Payload Ethernet Hub Bridge (PEHB) and replace it with an Improved Payload Ethernet Hub Gateway (iPEHG). The iPEHG design corrects performance limitations often experienced by the older PEHGs.

Atomization: The crew replaced sample syringes for the Atomization investigation today. The Atomization experiment investigates the disintegration processes of a low-speed water jet for various jet issue conditions in the Japanese Experiment Module (JEM) to validate the new atomization concept by observing the process using a high-speed camera. The knowledge gained can be applied to improve various engines utilizing spray combustion.

Binary Colloidal Alloy Test - Cohesive Sediment (BCAT-CS): The crew checked the camera alignment and focus by viewing the latest BCAT images on a laptop. They also performed battery change out for the camera flash. BCAT-CS focuses on the study of forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS makes it possible to separate the forces acting on the particles over a short range (adhesive forces) versus those acting over a long range (cohesive forces). The quartz/clay system is commonly found in a wide variety of environmental settings (such as rivers, lakes, and oceans) and plays an important role in technological efforts related to deep-sea hydrocarbon drilling and carbon dioxide sequestration.

Team Task Switching (TTS): A crewmember completed a Team Task Switching survey today. When crewmembers are required to switch their attention between tasks frequently, performance on each of the tasks can be negatively affected. The objective of the TTS investigation is to gain knowledge about whether or not crewmembers have difficulty in switching tasks and determine the impacts of these switches, in order to both reduce any negative consequences and improve individual and team motivation and effectiveness.

Spare External (EXT) Enhanced Processor and Integrated Communications (EPIC) Multiplexer/Demultiplexer (MDM) Card Swap: Based on the Test, Teardown and Evaluation (TT&E) study completed on the EXT-1 MDM that failed in 2017, teams believe the on-orbit EPIC cards could experience the same issue if subjected to cold temperatures below -20 Celsius. The crew removed the old, suspect EPIC card from the Spare EXT-1 MDM today and replaced it with a thermally tested replacement flown on OA-9 earlier this year. The MDM On-Orbit Tester (MOOT) hardware/software system will be used at a future date to perform an IVA functionality test of the MDM.

Node 3 (N3) Smoke Detector Relocate: When the new USOS Toilet System is launched and installed in N3, there will be an interference issue preventing easy access to the N3 cabin smoke detectors and forward HEPA Filters. While several options were considered to alleviate this interference, the decision was made to move the detectors from panel NOD3D3-03 to the plenum area under NOD3D3-01; the crew partially completed this activity this morning, aborting the relocation of one Smoke Detector due to a faulty fastener. Checkouts of the successfully relocated smoke detectors was nominal and teams are working the forward plan to re-install the remaining detector at a future time.

Public Affairs Office (PAO) Downlink Message: NASA is collaborating with National Parks Service to celebrate the 60th anniversary of NASA in conjunction with the 50th anniversary of the National Trails System Act. As part of that celebration, the crew took photos and video today with a toy mascot named Seaman Jr.; this "pupstronaut" represents a Newfoundland dog who traveled with Lewis and Clark through the entirety of their historic expedition. His collar inscription read "The greatest traveler of my species," and today's activity will inspire the next generation to be curious, brave, and excited to engage in Science, Technology, Engineering, and Math (STEM) fields.

STEMonstrations Recordings: One of NASA's education goals is inspire the next generation to enter the fields of Science, Technology, Engineering, and Math (STEM). "STEMonstrations," video lessons recorded by crewmembers on-board ISS, are one of the tools used by NASA to promote and teach the various STEM topics in an exciting way. As part of this initiative, crew recorded two STEMonstrations today, one on Solar Energy and the other on the Integrated Truss, for future use in educational products, NASA TV, and social media applications.
