Thinking Outside the Box

Faced with this unexpected challenge, the astronauts and mission control displayed remarkable ingenuity. They calmly analyzed the telemetry data and determined that a small piece of thermal insulation, later dubbed the “gumdrop” due to its resemblance to the candy, was likely lodged in the docking mechanism, preventing a proper seal. Time was of the essence, as the astronauts’ oxygen supplies were limited.

A Risky Maneuver

With limited options and the pressure mounting, the crew performed a daring maneuver. Schweickart, using a tool nicknamed the “poke tool,” carefully reached out of the LM and through the hatch of the CM. With only visual cues and limited time, he managed to dislodge the gumdrop from the docking tunnel. Thankfully, the maneuver proved successful, and after repressurizing the tunnel, the docking procedure was completed without further complications.
