National Aeronautics and Space Administration NASA 21 July The Apollo 11 landing site. to the Moon Credit: NASA on 21 July 1969, Neil Armstrong became the first man to walk on the Moon., The Apollo 11 landing site is near the distinctively large crater Theophilus to the right and southwest of the Moon’s centre. Choosing the Apollo landing sites to select where the Apollo missions would set down on the Moon, NASA shortlisted a series of potential landing areas near the lunar equator, where the Moon’s faster rotation speed would make it easier for the ascent stages to take off. Using Surveyor probes, the smoothest, crater-free locations for each final landing site were chosen.
For the later, longer missions, more emphasis was put on choosing areas that were geologically interesting.
Apollo 11: Sea of Tranquility
Aldrin’s boot prints remain enshrined at the Sea of Tranquillity (Mare Tranquillitatis), an area near the Moon’s equator, because there’s no wind or erosion to erase them. It’s almost due north to the equator and the pin-northwest of Moltke beneath three smaller craters, now named Aldrin, Collins and Armstrong after Apollo 11. Once thought to be a lunar ocean, the site is a relatively flat area with few boulders or craters. Credit: NASA
The two astronauts spent a total of two hours and 32 minutes on the surface of the Moon, travelled 1km and collected 21.55kg of samples for lunar field geology and deployed a passive seismic experiment package, a laser ranging retroreflector – to measure the distance between the Earth and the Moon – and a cosmic ray detector. The mission left 100 objects on the moon and American flag, and piece of lunar-the descent stage of the Eagle lunar lander. #nasa #apollo #history #exploration #rockets #research #engineering #transportation #science #aerospace #technology #engineering #goals #earth #satellites #flight #partnerships #international #science #aerospace #technology #engineering #goals #earth #satellites #flight #international #nasa #lunar #moon
