Apollo 11 spaceflight, first manned moon landing

Apollo 11 Spaceflight, First Manned Moon Landing

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.
The astronauts planted a specially designed U.S. flag on the lunar surface, in clear view of the TV camera. Some time later, President Richard Nixon spoke to them through a telephone-radio transmission which Nixon called "the most historic phone call ever made from the White House." Nixon originally had a long speech prepared to read during the phone call, but Frank Borman, who was at the White House as a NASA liaison during Apollo 11, convinced Nixon to keep his words brief, to respect the lunar landing as Kennedy's legacy.
The MESA failed to provide a stable work platform and was in shadow, slowing work somewhat. As they worked, the moonwalkers kicked up gray dust which soiled the outer part of their suits, the integrated thermal meteoroid garment.
