the first launch attempt in February 1969, an engine fire caused
the rocket to shut down and crash a minute after lift-off.
second test, in July 1969, was a greater disaster. The rocket shut
down seconds after lift-off, fell onto the launch pad, and exploded.

could reach the Moon ahead of the United States.
weeks later, the crew of Apollo 11 landed on the Moon.
