Apollo 15: NASA hits its stride.

FEATURES GLO:ast/01jul21:14n1.jpg PHOTO (COLOR): This view from the slopes of Mount Hadley Delta, near St. George Crater, takes in the Hadley Rille. ROVING HADLEY PLAIN GLO:ast/01jul21:19n1.jpg GRAPH: The total traverse distance of 17.5 miles (28.2 km) that Scott and Irwin traveled in the lunar rover was more than eight times longer than the two EVAs of Apollo 14, which were carried out on foot. Apollo 15 lifted off exactly on schedule July 26, 1971, at 9:34 a.m. EDT, keeping to a tight mission timeline that would ensure a favorable Sun angle when Scott and Irwin arrived at the Apennine Mountains on their landing approach. On the left is a boulder that Scott and Irwin sampled. [Extracted from the article]
