Apollo 11 spaceflight, first manned moon landing

Apollo 11 Spaceflight, First Manned Moon Landing

“After describing the surface dust as "very fine-grained" and "almost like a powder", Armstrong stepped off Eagle's footpad and uttered his famous line "That's one small step for man, one giant leap for mankind" six and a half hours after landing. Aldrin joined him, describing the view as 'Magnificent desolation.'”
About seven minutes after stepping onto the Moon's surface, Armstrong collected a contingency soil sample using a sample bag on a stick. He then folded the bag and tucked it into a pocket on his right thigh. This was to guarantee there would be some lunar soil brought back in case an emergency required the astronauts to abandon the EVA and return to the LM.
In addition to fulfilling President John F. Kennedy's mandate to land a man on the Moon before the end of the 1960s, Apollo 11 was an engineering test of the Apollo system; therefore, Armstrong snapped photos of the LM so engineers would be able to judge its post-landing condition. He removed the TV camera from the MESA and made a panoramic sweep, then mounted it on a tripod 68 feet (21 m) from the LM. The TV camera cable remained partly coiled and presented a tripping hazard throughout the EVA.
Armstrong said that moving in the lunar gravity, one-sixth of Earth's, was "even perhaps easier than the simulations... It's absolutely no trouble to walk around". Aldrin joined him on the surface and tested methods for moving around, including two-footed kangaroo hops. The PLSS backpack created a tendency to tip backwards, but neither astronaut had serious problems maintaining balance. Loping became the preferred method of movement. The astronauts reported that they needed to plan their movements six or seven steps ahead. The fine soil was quite slippery. Aldrin remarked that moving from sunlight into Eagle's shadow produced no temperature change inside the suit, though the helmet was warmer in sunlight, so he felt cooler in shadow.
