Two Russian astronauts ended their spacewalk earlier than planned on Wednesday, as one of them had a battery issue with his spacesuit, Russia's state space corporation Roscosmos said.
Cosmonauts Oleg Artemiev and Denis Matveev, members of the 67th long-term expedition to the International Space Station (ISS),
closed the exit hatch of the Poisk small research module at 20:54 Moscow time, completing their spacewalk that lasted 4 hours and 1 minute.
According to the plan, work overboard the ISS should last 6 hours and 44 minutes.
Due to a drop in battery voltage in the spacesuit,
Artemiev returned inside the Poisk module and connected the spacesuit to the onboard power supply, and Matveev also returned safely inside the station.
"Oleg, you must return to the airlock as soon as possible, because if you lose power, it is not only the pumps and the fan, you will lose comm, so you have to go back.
Oleg, we will take care of this with Denis. Your objective is to go back as soon as possible."
奥列格，我们会照顾好丹尼斯的 。你的任务是尽快回舱 。”
During the spacewalk, the Russian astronauts continued to prepare for the work of the European Robotic Arm (ERA),
and they installed two elbow cameras on the ERA and dismantled the launch ring from it.
"The astronauts are in good health. Work in progress will be completed during the next spacewalks," Roscosmos said.
“宇航员们的健康状况良好 。正在进行的工作将在接下来的太空行走中完成，”俄罗斯航天局如是说 。
