After more than four years in space, a "legendary" extravehicular suit returned to Earth aboard the Shenzhou-20 capsule on Monday. Known as "Spacesuit B," it supported 20 spacewalks over four years, far beyond its original design life. Shenzhou-21 crew commander Zhang Lu gave it an emotional farewell, calling it a "veteran comrade" that helped set extravehicular activity records. The suit will now be studied to inform future space technology development.
