Long March 5B rocket, often mentioned in news, was developed by
A. China
B. India
C. US
D. Russia
Explanation:
The debris came from the upper stage of a Long March 5B rocket– China’s largest– that had been launched into space on April 29 for putting into orbit a core module of the new Tianhe space station, which is expected to become operational in 2022. When a rocket is launched, its discarded booster stages re-enter the atmosphere soon after liftoff and harmlessly fall into the ocean– a standard practice.
