US EVA-84: In case the Soyuz MS-22 micrometeoroid impact 12/14 has you wondering, NASA says the calculated risk of a spacesuit penetration and oxygen leak of any size during a 6.5-hour EVA is in the neighborhood of 1-in-3,800; it's around 1-in-21,300 for a "critical" impact
US EVA-84: A critical impact in this context is one resulting in a penetration large enough to cause an uncontrollable loss of oxygen; NASA says the probabilistic risk assessment, emergency procedures, the suit's design and training combine to make make the risk acceptable
Watch live as two astronauts prepare for the first spacewalk of 2023! @NASA_Astronauts @AstroDuke and @Astro_Wakata of @JAXA_en will assemble and install modification kits required for upcoming solar array upgrades.
US EVA-84: For ID, Wakata, call sign EV-1, is wearing a suit with red stripes and using helmet camera No. 20; Mann, EV-2, is wearing an unmarked suit and using helmetcam 22
