NASA Space Station On-Orbit Status 14 July, 2020 - Focused on Two Final Power Upgrade Spacewalks

Two astronauts are concentrating on the final set of power upgrade spacewalks on the International Space Station beginning this week.

Meanwhile, their Expedition 63 crewmates continued focusing on biology research to ensure humans stay healthy in space during long-term missions.

Flight Engineer Bob Behnken and Commander Chris Cassidy for preparing for a pair of spacewalks to wrap up battery swaps and ready the orbiting lab for a new airlock. The duo collected and organized spacewalk tools then studied their tasks step-by-step on a computer during the afternoon. Fellow NASA astronaut Doug Hurley assisted the pair and installed their spacesuit batteries and metal oxide canisters to remove carbon dioxide from the suit.

Behnken and Cassidy will exit the station for the first spacewalk on Thursday. The spacewalk is scheduled to begin at 7:35 a.m. EDT. The spacewalkers will spend about seven hours removing aging nickel-hydrogen batteries and replacing them with new lithium-ion batteries on the Starboard-3 truss structure. NASA TV begins its live coverage at 6 a.m.

The second spacewalk is scheduled to start at the same time on Tuesday, July 21, for the final battery swaps to complete 3.5 years of external power upgrades on the space station. Behnken and Cassidy will then begin outfitting the Tranquility module for a new commercial airlock from NanoRacks. The airlock, designed to deploy public and private experiments, will be installed to Tranquility after its delivery later this year aboard the SpaceX Dragon cargo vehicle.

Meanwhile, a host of space science continues aboard the orbiting lab including human research to maintain healthy crews. NASA and its international partners are studying how the human body adapts to microgravity as they plan longer missions farther out into space.

The two cosmonauts from Roscosmos, Anatoly Ivanishin and Ivan Vagner, were once again exploring ways to stave off the negative effects of living in space. Vagner continued logging his meals and drinks and collected a blood sample for a study that seeks to reverse the loss of bone mass caused by microgravity. He later collected his saliva sample and attached a sensor to himself for an immune system investigation. Ivanishin exercised on a treadmill for a physical fitness evaluation and spent the rest of the day on communications and ventilation maintenance.

On-Orbit Status Report

Payloads

JEM Water Recovery System (JWRS): The crew retrieved the JEM WRS and performed inspections of the left, top and rear inside of the unit as well as checking fitting and coupler connections. Photos were taken and downloaded to the ground for evaluation. The Demonstration of JEM Water Recovery System (JWRS) generates potable water from urine. In the past on manned spacecraft, urine and waste water were collected and stored, or vented overboard. For long-term space missions, however, water supply could become a limiting factor. Demonstrating the function of this water recovery system on orbit contributes to updating the Environmental Control and Life Support System (ECLSS) to support astronauts on the space station and future exploration missions.

MAND (Manufacturing Device): The crew removed four calibration print wedges from the Manufacturing Device. The crew cleaned the extruder print nozzle. The print wedges were labeled, photographed and stowed. Power switches were set in preparation for the next print run. The Manufacturing Device enables the production of components on the ISS for both NASA and commercial objectives. Parts, entire experiments, and tools can be created on demand utilizing the MAND printer that is installed into an Express Rack locker location. MAND is capable of producing parts out of a wide variety of thermopolymers including engineered plastics.

Systems

Temperature and Humidity Control (THC) Common Cabin Air Assembly (CCAA) Swap: Today, the crew swapped from the S6 to the P6 CCAA in the Lab. Recently the Lab cabin temperature has been drifting slightly above the cabin setpoint, even with maximum airflow through the starboard CCAA Heat Exchanger (HX). Ground teams have already calculated the heat transfer for the S6 heat exchanger. The swapover will allow the team to perform the heat transfer calculations on the P6 CCAA HX to compare with the S6 CCAA HX.

Emergency Mask Procedure Review On-Board Training (OBT): The crew reviewed and practiced the emergency mask don/purge technique for an ammonia leak scenario. This is nominal training to maintain crew proficiency using emergency masks.

EVA Preparations: In preparation for US EVA #67 (S6 Battery EVA #3), the crew completed their pre-EVA tool configurations. Tomorrow, the crew will perform a final tool audit to ensure all of the necessary tools and configurations needed have been prepared. The crew also setup the EVA GoPro batteries for charging and then setup the EVA GoPro cameras. A checkout of the nitrogen quantity was performed on the Simplified Aid for EVA Rescue (SAFER) as well as charging operations on the Extravehicular Mobility Unit (EMU) Long Life Batteries (LLB) and Battery Stowage Assembly (BSA) batteries. Lastly the crew performed a visual review of the EVA using the Dynamic Onboard Ubiquitous Graphic (DOUG) software. This session allowed the crew to view the step-by-step sequence of the upcoming EVA.
