PREVIEW Three Chinese Astronauts Stranded on Space Station Without Lifeboat. Bob Zimmerman reports that three Chinese astronauts, or taikonauts, are currently aboard their space station without a lifeboat home, a situation he deems unprecedented and comparable to the Titanic. The status of their damaged spacecraft, possibly due to a cracked window, lacks transparency. It would be difficult to launch a replacement capsule within 10 to 20 days. Zimmerman also observes that the Chinese space program tends to cut corners, referencing incidents like dropping boosters on populated areas. Guest: Bob Zimmerman.
