Astrobee Powered On, Safety Drills, and Health Measurements Top Today’s Schedule

NASA astronaut and Expedition 69 Flight Engineer Woody Hoburg monitors an Astrobee robotic free-flyer in the Kibo laboratory module testing its operations in conjunction with mission controllers. The robotics work is being done to demonstrate ways to control the free-flyers using student-written code that recognizes multiple gestures.
NASA astronaut and Expedition 69 Flight Engineer Woody Hoburg monitors an Astrobee robotic free-flyer in the Kibo laboratory module testing its operations in conjunction with mission controllers. The robotics work is being done to demonstrate ways to control the free-flyers using student-written code that recognizes multiple gestures.

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.

Station Wraps Busy Week Before Cygnus Cargo Mission Launches

Image
This high exposure photograph from the International Space Station shows Earth’s atmospheric glow and a starry sky as the orbital complex soared above the Pacific Ocean. The Expedition 70 crew is looking ahead to the arrival of a U.S. cargo craft due to arrive at the International Space Station next week. Meanwhile, the Axiom Space 3 (Ax-3) crew finished its first week in orbit with a busy schedule of research, education, and media activities. Northrop Grumman’s Cygnus cargo craft will take its first ride atop a SpaceX Falcon 9 rocket when it lifts off at 12:29 p.m. EST on Monday from Kennedy Space Center in Florida. The private space freighter will be carrying over 8,200 pounds of science experiments, crew supplies, and lab hardware to the orbiting outpost. NASA Flight Engineer Jasmin Moghbeli is due to capture Cygnus with the Canadarm 2 robotic arm at 3:35 a.m. on Wednesday. She will be on duty that morning along with fellow NASA astronaut Loral O’Hara who will monitor Cygn...

NASA and Sierra Space are making progress on the first flight of the company’s Dream Chaser spacecraft to the International Space Station. The uncrewed cargo spaceplane is planned to launch its demonstration mission in 2024 to the orbital complex as part of NASA’s commercial resupply services. Credit: Sierra Space/Shay Saldana NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024. The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vib...

Crew Dragon Suit Checks as Station Begins Orbital Reboosts

Image
This long-exposure photograph from the space station reveals the Milky Way glittering above a bright but exaggerated atmospheric glow blanketing the Earth’s horizon. The Expedition 63 crew checked out SpaceX Crew Dragon suits today and stayed busy with a full slate of space research. The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October. Flight Engineers Doug Hurley and Bob Behnken inspected the suits they will wear when they return to Earth aboard the Crew Dragon spaceship. The duo tried on their suits for a fit check and ensured the components are in good condition. They are scheduled to depart the station on Saturday and splashdown the following day. NASA TV will cover all the departure activities live. The homebound-duo started the day replacing environmental control system (ECS) hardware aboard the orbiting lab. That work required temporarily removing a plant habitat from the Unity module to...
