Cosmonauts Encounter Toxic Coolant Mishap During ISS Spacewalk

A coolant leak from a radiator attached to the International Space Station (ISS) interrupted a spacewalk by Russian cosmonauts Oleg Kononenko and Nikolai Chub. The leak occurred while the cosmonauts were inspecting a backup radiator on Russia's Nauka laboratory module. Although the coolant did not reach their suits, the cosmonauts were instructed to leave the area for safety. This is the third incident of a coolant leak from Russian hardware on the ISS, raising concerns about the integrity of the equipment. NASA claims that operations on the ISS are unaffected, with rescheduled spacewalks planned.
