Fourth Spacewalk of Anil Menon: Objectives of the Spacewalk

On 29th October, 2026 Anil Menon conducted the spacewalk with the Canadian Space Agency astronaut Joshua Kutryk. This spacewalk was categorized as the 100th US spacewalk at the International Space Station.

The primary task was to install a new roll-out solar array on the space station.

Solar arrays are a source of electrical energy obtained from converting sunlight using photovoltaic cells. Solar arrays provide electrical energy for various functions such as life support system and communications equipment among others in the International Space Station.

Spacewalks help the astronauts work on the external equipment that cannot be fixed from inside the space station.
