Botany and physics topped the research schedule as spacewalk cleanup duties continued aboard the Sustaining crews independently of cargo missions and taking advantage of microgravity for better manufacturing techniques are key targets for
Plant Studies and Manufacturing Techniques
NASA Flight Engineer Frank Rubio set up seed bags for the Plant Habitat-03B study to understand how characteristics of plants grown in space change from one generation to the next. Results may inform ways to grow repeated generations of space crops to support future crewed missions. UAE (United Arab Emirates) astronaut Sultan Alneyadi worked in the Microgravity Science Glovebox servicing samples to learn how to manufacture superior SUBSA-μgGA physics study seeks to benefit Earth and space industries for better power storage, environmental protection, and chemical sensing.
Life Support Maintenance
The duo also assisted NASA Flight Engineer Woody Hoburg who worked throughout Friday swapping life support gear in the Tranquility module. A failed heat exchanger was removed and a new one was installed then connected to new low temperature loop hoses. NASA Flight Engineer Stephen Bowen aided his crewmates on Friday photographing Alneyadi’s research work and helping Hoburg during his life support maintenance. Bowen later removed sensors that measured his blood pressure and downloaded the data to doctors on the ground.
Spacewalk Cleanup and Tools Stowage
Cosmonauts Sergey Prokopyev and Dmitri Petelin continued cleaning their spacesuits and stowing tools and accessories following Wednesday’s spacewalk to install orbital debris shields and relocate a portable workstation.
ISS Reboost and Altitude Adjustment
The Northrop Grumman Cygnus cargo spacecraft’s delta velocity thruster fired at 10:35 a.m.
The reboost also continued the certification of the use of Cygnus as a second spacecraft currently capable of conducting such a maneuver. The Cygnus reboost increased the station’s altitude by 3/10 of a mile at apogee and 2.8 miles at perigee and put the space station in an orbit of 262.5 x 257.6 statute miles.
Preparations for SpaceX Crew-7 Mission
Crew members who will soon fly aboard NASA’s SpaceX Crew-7 mission will enter quarantine Friday in one of the major milestones before they head to the launch site in Florida to start their mission to the International Space Station. The company’s Falcon 9 rocket is targeted to launch Crew-7 no earlier than 3:49 a.m. EDT on Friday, Aug. 25 from Launch Complex 39A at Kennedy.
