NASA is targeting a spacewalk for no earlier than Friday to replace a failed power controller, also known as the battery charge-discharge unit (BCDU). The Expedition 61 crew is adjusting its schedule this week to accommodate the new spacewalk plans at the International Space Station.

Astronauts Christina Koch and Jessica Meir are continuing their preparations for the upcoming excursion. The duo will set their suits to battery power on Friday at 7:50 a.m. when the spacewalk officially starts and exit the Quest airlock. NASA TV begins its live coverage beginning at 6:30 a.m.

The pair in their U.S. spacesuits will venture to the far side of the station on the Port 6 truss structure. Once there, the spacewalkers will take about five-and-a-half hours to replace the failed power regulator with a spare BCDU. The BCDU had been in operation since December 2000 and is due to return to Earth on the next SpaceX Dragon resupply ship for inspection. The device regulates the charge to batteries that collect and distribute power to the station.

Station managers will investigate the loss of the BCDU and reschedule the three battery replacement spacewalks for a future date. In the meantime, the five planned spacewalks to repair a cosmic particle detector, the Alpha Magnetic Spectrometer, are still on the calendar for November and December.

  1. Great Spacewalk. Question. Why are the stars matted out from any views from the space station.? I would love to see them . living in a brightly lit city I no longer can see them. I miss the Stars and planets. Being 67 I know I do not have many decades to see them.

    1. The brightness of the Earth and station lights in the cameras focused on the spacewalkers dominates the very distant and dim stars by comparison just like city lights on Earth.
