Apollo 11 spaceflight, first manned moon landing

Apollo 11 Spaceflight, First Manned Moon Landing

During this period Mission Control used a coded phrase to warn Armstrong that his metabolic rates were high and that he should slow down. He was moving rapidly from task to task as time ran out. However, as metabolic rates remained generally lower than expected for both astronauts throughout the walk, Mission Control granted the astronauts a 15-minute extension.
• Lunar ascent and return
Aldrin entered Eagle first. With some difficulty the astronauts lifted film and two sample boxes containing more than 22 kilograms (49 lb) of lunar surface material to the LM hatch using a flat cable pulley device called the Lunar Equipment Conveyor. Armstrong reminded Aldrin of a bag of memorial items in his suit pocket sleeve, and Aldrin tossed the bag down; Armstrong then jumped to the ladder's third rung and climbed into the LM. After transferring to LM life support, the explorers lightened the ascent stage for return to lunar orbit by tossing out their PLSS backpacks, lunar overshoes, one Hasselblad camera, and other equipment. They then pressurized the LM, and settled down to sleep.
While moving within the cabin, Aldrin accidentally broke the circuit breaker that would arm the main engine for lift off from the Moon. There was concern this would prevent firing the engine, stranding them on the Moon. Fortunately a felt-tip pen was sufficient to activate the switch. Had this not worked, the Lunar Module circuitry could have been reconfigured to allow firing the ascent engine.
