During a ceremony at the Casa Rosada in Buenos Aires on Thursday, July 27, Argentina became the 28th country to sign the Artemis Accords. NASA Administrator Bill Nelson participated in the signing ceremony for the agency, and Daniel Filmus, Minister of Science, Technology, and Innovation, signed on behalf of Argentina.

The Expedition 69 crew members carried out more station maintenance activities today aboard the International Space Station as they gear up for a busy month of mission events in August.
NASA astronaut Stephen Bowen was tasked with troubleshooting water supply hoses and replacing connections in the Glovebox Freezer, which integrates into the Life Sciences Glovebox sealed work space to rapid freeze biological samples. Additionally, Bowen removed samples from Iceberg for future assessment, which provides cold stowage for science and research aboard the orbital lab.
NASA astronaut Woody Hoburg and United Arab Emirates (UAE) Flight Engineer Sultan Alneyadi began their day collecting samples for the Standard Measures investigation. Hoburg later completed a cognition test for the ongoing assessment of human spaceflight risks for astronauts before, during, and after long-duration space missions. Midafternoon, he removed the Small Satellite Orbital Deployer from the Japanese Experiment Module after mini satellites were successfully deployed earlier this month.
Meanwhile, Alneyadi powered off Astrobee following yesterday’s Zero Robotics dry-run session and installed sample holders for MATISS—an investigation of antibacterial properties of materials in space. He ended his day inspecting crew safety tethers and gathering tools for future Extravehicular Activities (EVAs) or spacewalks, as well as consolidating food in preparation for the upcoming cargo delivery on Northrop Grumman’s Cygnus spacecraft.
Cygnus is targeted to launch at 8:31 p.m. EDT on Tuesday, August 1 from NASA’s Wallops Flight Facility in Virginia. More than 8,200 pounds of supplies and science will be delivered to the crew on Friday, August 4, marking the company’s 19th commercial resupply mission.
NASA Flight Engineer Frank Rubio enjoyed a well-deserved day off ahead of a busy day of tasks tomorrow.
Commander Sergey Prokoypev of Roscosmos is making headway on the cargo plan preparation for the upcoming ISS Progress 85 mission in August, spending most of his day between prep and performing maintenance in the Zvezda module. Flight Engineer Dmitri Petelin carried out additional experiments of liquid phases in microgravity, while Flight Engineer Andrey Fedyaev completed more upkeep activities in the Nauka module.
The space station is orbiting slightly higher after the 83P fired its engines for five minutes on Thursday. The orbital reboost raises the station to the correct altitude for the upcoming docking of the ISS Progress 85 resupply mission.

Another round of safety training is underway today on the International Space Station. The Expedition 69 crew members were also tasked with robotic activities, ultrasound scans and station maintenance.
United Arab Emirates (UAE) Flight Engineer Sultan Alneyadi powered on the station’s free-flying robots, Astrobee, in the morning. Later in the day, NASA astronaut Woody Hoburg performed a Zero Robotics dry run with Astrobee in the Japanese Experiment Module and assisted grounds teams with multiple software test runs. In dry run sessions, the Astrobee robots verify various aspects and programming for the Zero Robotics student competition—a program that provides students the opportunity to write software that controls one of three Astrobee robots, helping inspire the next generation of explorers, scientists and engineers.
Alneyadi was also tasked with consolidating food as the crew preps for the berthing of Northrop Grumman’s 19th commercial resupply mission, targeted for launch on Tuesday, August 1 and capture on Friday, August 4.
NASA astronaut Stephen Bowen was joined by Hoburg in the afternoon to take ISAFE measurements. In the microgravity environment, blood and fluids shift toward the head, which can cause structural changes to the eye. ISAFE measures eye, brain and blood vessel changes in microgravity using an ultrasound device in order to help researchers better predict eye changes on future long-duration spaceflight.
NASA Flight Engineer Frank Rubio performed computer maintenance in the Japanese Experiment Module in the morning. He then completed maintenance tasks on the Confocal Space Microscope, a Japanese Aerospace Exploration Agency facility that provides fluorescent images of biological samples. At the end of the day, Rubio, joined by Alneyadi, Hoburg, Bowen and Commander Sergey Prokopyev and Flight Engineers Dmitri Petelin and Andrey Fedyaev of Roscosmos, all completed a second set of safety drills.
Ahead of training, Prokopyev completed maintenance tasks in the Zvezda service module while Fedyaev took inventory in the Functional Cargo Block, or Zarya module, and Petelin ran additional experiments studying liquid phases in microgravity.
Mission Control Center Houston is back to normal operations after full communication with the International Space Station was restored July 25, following a loss of power to the space station’s primary ground communication equipment at NASA’s Johnson Space Center. The issue occurred during planned upgrades to the ground power system to ensure the mission control power grid remains robust and reliable. Ground teams activated the backup control center systems located at the agency’s Marshall Space Flight Center in Huntsville, Alabama, to regain communications with the space station while engineers addressed the power issue in Houston. The backup systems typically are used in events such as a hurricane when evacuation from Mission Control Center Houston may be necessary. Flight controllers in Houston were able to stay in contact with the Expedition 69 crew aboard the space station through Roscosmos, as well as backup channels and the crew was not in any danger. All check-outs of the equipment went as planned following repowering.
