Indian-origin NASA astronaut Sunita Williams on Thursday stepped out of the International Space Station (ISS) for a spacewalk along with colleague Nick Hague, the US space agency said.

Sunita Williams, one of the two NASA astronauts stranded on the ISS, completed her first spacewalk since arriving over seven months ago. NASA described the mission as crucial for maintaining the ISS's smooth operation and extending its life.

Indian-origin NASA astronaut Sunita Williams returned to spacewalking after a 12-year break, stepping outside the International Space Station (ISS) alongside astronaut Nick Hague for US Spacewalk 91.
