What primary objective of Apollo 13 was officially aborted due to the in-flight emergency?
Answer
Placing astronauts on the lunar surface
The central goal of the Apollo 13 mission, like its predecessors, was to execute a third successful lunar landing and allow astronauts to walk on the Moon. However, following the explosion in the Service Module, Mission Control and the crew immediately pivoted from exploration to survival. Because the necessary life support and power systems housed in the main vehicle were compromised, the primary mission objective—landing on the Moon—had to be completely called off, marking the mission a failure in terms of its initial scientific and exploration mandate.
