Earlier in 2020, there were already three exits on the American program.
“The first two exits of Cassidy and Behnken to replace the batteries are scheduled for June 26 and July 1,” the source said.
Earlier, NASA materials indicated that four outlets would be required to replace the batteries. Six new batteries for the power supply system of the American segment of the ISS were delivered by the Japanese cargo ship HTV-9 at the end of May.
Now on the ISS, in addition to Cassidy and Behnken, Russians Anatoly Ivanishin and Ivan Wagner, as well as American Douglas Hurley, are flying.
