Recent space station arrivals Thomas Marshburn and Kayla Barone will exit the ISS on Tuesday, Nov. 30, to work on a faulty antenna system.

The two astronauts will work together to replace a malfunctioning S-band antenna system, which is pre-fixed to the station’s truss structure, Nasa said in a message posted Sunday, explaining that the space station “transmits low-rate voice and data over the S-band of radio frequencies to flight controllers on the ground.” It added that although the issue is having limited impact on the operation of the station, now is the best time to change it.


Tuesday’s extra-curricular activity – as the spacewalk is officially known – will be the fifth for Marshburn, whose previous walks took place in 2013 and 2009. This is Baron’s first space mission, so she will venture outside the station for the first time.

The most recent ISS spacewalk took place in September 2021 and was conducted by astronaut Thomas Pesquet of the European Space Agency and Akihiko Hoshide of the Space Agency of Japan.
