Astronauts Drew Morgan and Christina Koch floated back outside the International Space Station Friday and completed work to replace six aging batteries with three more powerful units in one of the lab’s eight solar power circuits. Three more spacewalks are planned over the next two weeks to replace another six batteries in an adjacent circuit.
Astronauts Christina Koch and Andrew Morgan floated outside the International Space Station Sunday and completed a 7-hour, 1-minute spacewalk to begin replacing batteries on the far left side of the research outpost’s solar array truss, the first of up to six excursions scheduled before the end of October.
After a spacesuit sizing problem prevented an all-female spacewalk earlier this year, astronauts Christina Koch and Jessica Meir will get a chance to make history Oct. 21 when they venture outside the International Space Station in the fourth of five excursions to install a new set of solar array batteries, NASA managers announced Friday.
Two weeks after a launch pad fire forced a delay, a Japanese H-2B rocket lifted off Tuesday with an HTV cargo freighter to deliver upgraded batteries, experiments and provisions to the International Space Station. Liftoff from the Tanegashima Space Center occurred at 1605 GMT (12:05 p.m. EDT) Tuesday.
Mitsubishi Heavy Industries, the prime contractor for Japan’s H-2B rocket, said Friday that engineers concluded a fire on the launch pad during a countdown earlier this month was most likely sparked by static electricity and stimulated by oxygen. The H-2B rocket launch has been rescheduled for Tuesday to start a resupply mission to the International Space Station.
