Crashing Chinese rocket highlights growing dangers of space debris

This weekend, a Chinese rocket booster, weighing nearly 23 tons, came rushing back to Earth after spending more than a week in space--the result of what some critics, including NASA Administrator Bill Nelson, have attributed to poor planning by China. Pieces of the rocket, dubbed Long March 5B, are believed to have splashed down in the Indian Ocean near the Maldives, and no one was injured.
