Then we refined on the Moon, we are still learning from mankind’s photo locations using local geology and the Sun angle excursion to the Ocean of Storms. A complete in the Hasselblad photos [1]. We matched equipment understanding of the formation history of the landing and sampling stations in the Hasselblad pictures to the site requires precise knowledge of where samples were descriptions in the transcripts [10-11] and audio [2]. collected, photos were taken, and equipment was We also converted PSE data [5] into real-time videos deployed. We documented astronaut activities from in MATLAB, then synchronized them with audio [2] Apollo data and subsequent studies [1-13] in a and video [3-4], producing one synchronized video per spatiotemporal map, drawing on methods devised for a EVA. Filling in gaps in the DAC and TV footage with similar effort on the Apollo 11 site [14]. For both the the real-time PSE data [5] refined the timing of each Apollo 11 and 12 sites we used images, audio, and performed task (Fig. 1). Apollo 12 had the first true video [1-4] to spatially locate points, then used geologic traverse on the Moon, making the precise transcripts [10-11] to temporally locate points, location of sample collection vital.
