Heart Studies, AC and Plumbing Work Fill Orbital Schedule

An Expedition 63 crew member aboard the space station photographed the well-lit, highly populated areas of Pakistan and northern India during an orbital night period.
An space station crew member photographed the well-lit, highly populated areas of Pakistan and northern India during an orbital night period.

The three-person Expedition 63 crew focused its attention today on Japanese science hardware and Russian cardiac studies. The International Space Station trio also serviced air conditioning and plumbing systems.

The Kibo laboratory module from JAXA (Japan Aerospace Exploration Agency) enables a multitude of space science taking place both inside and outside the orbital lab. Kibo has an airlock that the crew can place external experiments and even satellites for deployment into the vacuum of space.

Commander Chris Cassidy spent the first part of Thursday removing a commercial science payload from Kibo’s airlock. The NanoRacks External Platform supports a variety of research requiring exposure to the space environment. The automated science experiments look at different technologies and phenomena including robotics, physics, and microbiology that can benefit Earth and space industries.

Cassidy switched roles in the afternoon from space scientist to orbital maintenance man. The veteran NASA astronaut checked out spacecraft atmosphere monitor components and updated software supporting the Waste and Hygiene Compartment, the station’s restroom.

Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner continued a second day of heart research to understand how the human body adapts to long-term weightlessness. The duo explored the benefits of a negative pressure lower body suit that prevents blood and body fluids from pooling toward an astronaut’s head, a unique space condition commonly known as “puffy face.”

Ivanishin also replaced battery components before setting up advanced Earth photography gear. Vagner worked on fluid transfers throughout the station’s Russian segment then moved on and updated lab inventory files.

Credit: NASA TV NASA astronauts Jasmin Moghbeli and Loral O’Hara concluded their spacewalk today at 2:47 p.m. EST after 6 hours and 42 minutes. Moghbeli and O’Hara were able to complete one of the spacewalk’s two major objectives, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station. Mission Control told the station crew that the solar array is functioning well after the bearing replacement. Spacewalkers also removed a handling bar fixture to prepare for future installation of a roll-out solar array and properly configured a cable that was previously interfering with an external camera. The astronauts had planned to remove and stow a communications electronics box called the Radio Frequency Group, but there w

Astronauts (from left) Jasmin Moghbeli and Loral O’Hara are pictured inside the International Space Station’s cupola holding NASA’s first graphc novel, “First Woman.” Human research and space physics were the dominant science topics aboard the International Space Station on Thursday. The Expedition 70 crew is also preparing for a U.S. cargo mission targeted to launch next week. NASA astronaut Jasmin Moghbeli and Roscosmos cosmonaut Konstantin Borisov took turns as crew medical officer on Thursday and performed eye scans of their crewmates using the Ultrasound 2 device . Moghbeli operated the device imaging the eyes of Commander Andreas Mogensen and Flight Engineer Satoshi Furukawa . Borisov also scanned Roscosmos Flight Engineer Nikolai Chub’s eyes. Doctors on the ground monitored and assisted the diagnostic exam in real-time. The ultrasound scanning procedure uses high-frequency soundwaves to observe how microgravity affects a crew member’s eye structure. Afterward, Mogensen

Spacewalkers Installing Solar Array Live on NASA TV

Astronaut Stephen Bowen is pictured exiting the space station’s Quest airlock and beginning a spacewalk on April 28, 2023. NASA Television coverage of today’s spacewalk with NASA astronauts  Steve Bowen and Woody Hoburg is now underway and is also available on the  NASA app , the  space station blog  and the agency’s  website . The crew members of Expedition 69 are preparing to exit the  International Space Station ‘s Quest airlock for a spacewalk expected to begin about 9:15 a.m. EDT and last about seven hours. Bowen and Hoburg will install an IROSA (International Space Station Roll-Out Solar Array) to augment power generation for the 1A power channel on the station’s starboard truss structure. The new arrays are 60 feet long by 20 feet wide (18.2 meters by 6 meters) and will shade a little more than half of the original arrays, which are 112 feet long by 39 feet wide. Each new IROSA will produce more than 20 kilowatts of electricity, and once all are installed, will enable a
