NASA Space Station On-Orbit Status 13 March 2019 - Crew Set to Expand to Six.

The last full day of Expedition 58--before the launch, docking and consolidation of crews to become Expedition 59--was mostly spent on housekeeping items for the continued, successful operation of the International Space Station.

NASA astronaut Anne McClain floated through the Tranquility and Zvezda service modules, deploying acoustic monitors. She paused in the U.S. lab at an EXPRESS rack to install communications gear and perform additional maintenance. David Saint-Jacques of the Canadian Space Agency also worked with EXPRESS today, moving Space Automated Bioproduct Labs from rack-1 to rack-2. This miniature laboratory within the larger orbiting laboratory supports life science research, hosting microorganisms (bacteria, yeast, algae, fungi, viruses, etc.), small organisms, animal cells, tissue cultures and small plants for evaluation in space.

Expedition Commander Oleg Kononenko of Roscosmos replaced fuel bottles on the Combustion Integrated Rack, which allows the crew members to conduct fluids and combustion studies in microgravity.

Today in Baikonur, Kazakhstan, NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmos, were certified for flight by the Russian state commission and held their final news conference.

Tomorrow, the soon-to-be station residents will hitch a ride aboard a Soyuz MS-12 for blastoff at 3:14 p.m. EDT on, coincidentally, 3/14. After a relatively speedy six-hour flight, the Soyuz is expected to dock to station's Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking.

The events will unfold live on NASA TV, with launch coverage beginning at 2 p.m. and docking coverage at 8:15 p.m., respectively. After a brief break, tune in at 10:30 p.m. for the hatch opening and welcome, which will return the orbiting laboratory's population to six--including three NASA astronauts. And, just in time for Women's History Month, this launch marks the fourth Expedition crew with two female astronauts.

On-Orbit Status Report

Combustion Integrated Rack (CIR) Manifold Bottle Replacement: The crew removed a 50% ethylene fuel bottle and replaced it with a 100% ethylene bottle. They also installed a 100% helium bottle. This is in support of the ongoing BRE (Burning Rate Emulator) experiment, which is part of the ACME (Advanced Combustion via Microgravity Experiments) suite of experiments. The BRE experiment runs are focused on spacecraft fire prevention. More specifically, BRE's objective is to improve our fundamental understanding of materials flammability and to assess the relevance of existing flammability test methods for low and partial-gravity environments.

Circadian Rhythms: In conclusion of the current experiment run, the crew member removed the Double Sensors and Thermolab Unit, cleaned the Double Sensors and stowed the equipment. This completed the 4th session for this crewmember. Circadian Rhythms investigates the role of synchronized circadian rhythms, or the "biological clock," and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers' circadian clocks.

Express Rack (ER)-1 Upgrade: The crew replaced the Payload Ethernet Hub Gateway (PEHG) within ER-1 in the Lab and replaced it with a new Improved Payload Ethernet Hub Gateway (iPEHG). This upgrade is part of an ongoing effort to replace PEHG within Payload Racks with iPEHG. The new iPEHG provides 100 Mbps ethernet services, digital video enabled over ethernet, and increased High Rate Data Link (HRDL) fiber optic bandwidth. While the rack was rotated, the crew also took the opportunity to remove the UBNT (Ultrasound Background Noise Test) hardware from this area. The UBNT experiment was completed some time ago, and a rack rotation is required to access much of the hardware.
