Credit: NASA TV NASA astronaut Steve Bowen and UAE (United Arab Emirates) astronaut Sultan Alneyadi concluded their spacewalk at 4:12 p.m. EDT after 7 hours and 1 minute. Bowen and Alneyadi laid cables and installed insulation on mounting brackets on the starboard truss of the station for the installation of the next pair of International Space Station Roll Out Solar Arrays ( iROSAs ). The astronauts were unable to free up an electronics box located on the truss associated with a degraded S-band communications antenna. The antenna removal was deferred to a future spacewalk ahead of its planned return to Earth. The installation is part of a series of spacewalks to augment the International Space Station’s power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four iROSAs have been installed so far, an

NASA astronaut Steve Bowen and UAE (United Arab Emirates) astronaut Sultan Alneyadi began a spacewalk at 9:11 a.m. EDT to prepare for future installation of upgraded solar arrays on the starboard side of the station’s truss. The astronauts will then retrieve S-band antenna equipment and bring it inside the space station for refurbishment. The spacewalk is part of a series to augment the station’s power channels with new International Space Station Roll-Out Solar Arrays ( iROSAs ). Four of the new arrays have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks following their arrival this year on SpaceX’s 28th commercial resupply services mission for NASA.

Credit: NASA TV At 7:22 a.m. EDT, Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm which earlier detached Cygnus from the Earth-facing port of the International Space Station ’s Unity module. At the time of release, the station was flying southwest of Ireland. The Cygnus spacecraft successfully departed the space station more than five months after arriving at the microgravity laboratory to deliver about 8,200 pounds of supplies, scientific investigations , commercial products, hardware, and other cargo for NASA. Following a deorbit engine firing later Friday evening, Cygnus will begin a planned destructive re-entry, in which the spacecraft – filled with trash packed by the station crew – will safely burn up in Earth’s atmosphere. Cygnus arrived at the space station Nov. 10, following a launch on Northr

The three cosmonauts aboard the orbital outpost slept in following an overnight spacewalk to move and install hardware. The latest space biology experiment taking place on the station explores how living long-term in weightlessness affects an astronaut’s eyes and brain. The lack of gravity causes blood and cerebrospinal fluid to shift toward the head creating ocular and cranial pressure. NASA astronauts Stephen Bowen and Woody Hoburg studied that phenomena Wednesday morning and ways to offset the space-caused symptoms by collecting their blood pressure measurements and scanning their chests with the Ultrasound

The SpaceX Dragon resupply ship approaches the station 261 miles above the Indian Ocean on March 16, 2023. Biology research, cargo packing, and spacewalk preparations continue aboard the International Space Station as the Expedition 69 crew goes into a very busy April. NASA Flight Engineers Stephen Bowen and Woody Hoburg have been working on a variety of space experiments since their delivery aboard the SpaceX Dragon cargo craft on March 16 . The two astronauts, with assistance from NASA Flight Engineer Frank Rubio , are finalizing one experiment today by packing space biology samples and research hardware inside Dragon for its return to Earth this weekend. The completed study will help scientists understand how an astronaut’s body adapts to living long-term in weightlessness. They will continue more science-packing activities on Friday. The three NASA astronauts, including UAE (United Arab Emirates) astronaut Sultan Alneyadi , will also be on duty Saturday morning completing
