Akihiko Hoshide (52), an astronaut who has been housed on the International Space Station (ISS) for a long time as a captain, conducted extravehicular activities from the night of the 12th to the early morning of the 13th Japan time. He teamed up with a French airman to play the lead role and completed preparatory work to install the new solar panel. This is the 11th Japanese extravehicular activity after Soichi Noguchi (56) in March. Mr. Hoshide, which was the fourth time, had a cumulative total of more than 28 hours of extravehicular activity, surpassing Mr. Noguchi to become the longest Japanese.
Hoshide and Thomas Pesquet (43) started EVA at 9:15 pm on the 12th after preparing for the prevention of decompression sickness. NASA is working to add a new panel to complement the production of aging solar panels. This time, a bracket was placed to add a new panel to the base of one of the eight existing panels on the ISS. In March, Mr. Noguchi was doing the same job on another panel.
Subsequently, the two replaced the device that measures the potential of the ISS. The data is acquired to investigate measures against the charging and discharging of solar cell panels in space but was replaced by a new one due to a failure. Mr. Hoshide also replaced the pin in the hinge portion of the outboard with the outboard motor, which was a candidate for additional work to be done when there was time to spare.
After 6 hours and 54 minutes of work, the activity ended at 4:09 am on the 13th. Hoshide’s extravehicular activity totaled 28 hours and 17 minutes, surpassing Noguchi’s 27 hours and 1 minute in four times, which makes him the oldest Japanese man.
Around 8 am, Hoshide said on Twitter: “I was able to safely terminate the extravehicular activity. In addition to the team that planned and executed the extravehicular activity, NASA includes controllers, engineers, safety confirmation personnel, and training personnel. I believe That was made possible with the cooperation of all the crew members who participated in the ISS and all the crew members who stayed on the ISS. Thank you very much! ”
Initially scheduled for August 24 and 25, it was postponed due to consideration of the physical condition of the Americans who were supposed to be Hoshide’s companions. Made by switching from American to Pesuke. It was the first time in history that NASA’s EVA was conducted without Americans.
Mr. Hoshide made his first flight on the space shuttle “Discovery” in 2008 and carried out work to install the Japanese Experimental Module “Kibo” on the ISS. During his long 12-year stay, he performed EVA three times to replace the ISS power supply. This is my third flight and I will be staying on the ISS for about half a year starting in April. He is the second Japanese captain after Koichi Wakata (58) in 2014.
