NASA Space Station On-Orbit Status 23 May 2019 - Station’s Altitude Increased by 4KM (2.5 miles).

The Expedition 59 astronauts focused on DNA editing, high-end physics and free-flying robotics aboard the International Space Station today. Two cosmonauts are also ramping up their preparations for next week's spacewalk.

A docked Russian cargo craft fired its thrusters for 20 minutes today increasing the station's altitude by about 2.5 miles. The orbital reboost places the station in the correct trajectory for the undocking and landing of three Expedition 59 crewmembers June 24.

The wide range of advanced space research taking place every day on the orbiting lab benefits humans on Earth and in space. Scientists use the results to treat terrestrial ailments and the negative impacts of microgravity more effectively. Engineers also take the data to improve industrial and commercial processes and design safer, more advanced spacecraft and habitats as NASA prepares to go to the Moon in 2024.

NASA astronaut Nick Hague is researching how space radiation damages DNA today using the CRISPR genome-editing tool. The Genes in Space-6 study also uses DNA extraction and sequencing tools to observe how the damaged DNA repairs itself in space. Results may advance the development of treatments for radiation exposure hazards in harsh environments.

Space manufacturing eliminates the detrimental effect of Earth's gravity and may provide superior results than on the ground. Flight Engineer Christina Koch of NASA set up hardware in the Microgravity Science Glovebox to explore the production of high-quality optical fibers on the station. The study seeks to create a high commercial value product benefitting both Earth and space industries.

The Astrobee robotic assistant is being checked out today by Canadian Space Agency astronaut David Saint-Jacques. He set up the cube-shaped robotic free flyer to map the inside the of Kibo laboratory module and spun it rapidly afterward calibrating its navigation camera. Astrobee is being tested for its ability to perform routine maintenance duties and provide additional lab monitoring capabilities.

Two cosmonauts are ensuring their physical readiness and outfitting a pair of Russian Orlan spacesuits ahead of a May 29 spacewalk. Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin each spent over an hour on an exercise bike today measuring their cardiovascular response. Flight surgeons want to make sure the spacewalkers are able to endure the several hours of intense physical exertion. The duo also installed lights and other components onto the spacesuits.

On-Orbit Status Report

JAXA Mouse Mission: The crew performed blood draws and cage water maintenance for the Mouse Mission experiment. The purpose of this mission is to analyze alterations of the gene expression patterns in several organs and the effects on the germ-cell development of mice exposed to a long-term space environment.

Genes in Space-6: The crew performed photography and provided observation notes for the CRISPR yeast growth media plates. Colonies were selected for DNA extraction and amplification using the miniPCR16 DNA analyzer. Deoxyribonucleic acid (DNA) damage caused by increased exposure to radiation can affect the long-term health of astronauts. The experiment determines the optimal DNA repair mechanisms that cells use in the spaceflight environment. The investigation evaluates the entire process in space for the first time by inducing DNA damage in cells and assessing mutation and repair at the molecular level using the miniPCR and the Biomolecule Sequencer tools aboard the space station.

Astrobee: The crew performed Astrobee module mapping in preparation for future free flyer operations. This was a repeat of a previous mapping attempt. Astrobee is a series of three free-flying, cube-shaped robots. The robots are designed to help scientists and engineers develop and test technologies for use in microgravity to assist astronauts with routine chores, and give ground controllers additional eyes and ears on the ISS. The autonomous robots, powered by fans and vision-based navigation, perform crew monitoring, sampling, logistics management, and accommodate up to three investigations.

Fiber Optic Production (FOP): The crew installed the FOP hardware into the Microgravity Science Glovebox (MSG), changed out the preform and spools and activated the facility in preparation for the next operation run which is initiated from the ground. The investigation creates optical fibers with high commercial value aboard the ISS using a blend of zirconium, barium, lanthanum, sodium, and aluminum called ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF). It operates in the Microgravity Science Glovebox (MSG). Extensive theoretical studies along with a limited number of experimental studies suggest that ZBLAN optical fibers produced in microgravity should exhibit far superior qualities to those produced on Earth. The resulting optical fiber from Fiber Optic Production is expected to help verify these studies and guide further engineering efforts to manufacture high value optical fiber in large volume aboard the ISS.

Laboratory (Lab) Charcoal HEPA Integrated Particle Scrubber (CHIPS) Filter Install: Today the crew removed six existing bacteria filters in the Lab and replaced them with the new CHIPS filters that were delivered on NG-11. By adding charcoal to the filter system, experts hope to scrub volatile siloxanes from the air before they can affect other ISS systems. Installing these filters on ISS is a key objective for NASA's exploration vehicle programs because data collected after the install will determine how charcoal affects the life of the Water Processor Assembly (WPA) and other downstream hardware. These filters have already been installed in both Node 2 (N2) and Node 3 (N3).

71 Progress (71P) ISS Reboost: At 11:08 AM CT, the ISS performed a 2.56 meter/second reboost, with a duration of 19 minutes and 56 seconds, using 71P thrusters. This reboost, which increased ISS altitude by 4.4 km, was required to start phasing of the ISS orbit in preparation for 57S undock scheduled on June 24.
