Between the first launch on April 12, 1981, and the final landing on July 21, 2011, NASA's space shuttle fleet -- Columbia, Challenger, Discovery, Atlantis and Endeavour -- flew 135 missions, helped construct the International Space Station and inspired

The program began with the various designs and estimates that were given to Nixon and his Budget Office, and in 1972, they gave a go ahead for a specific development plan. After the system was developed, the first prototype, Enterprise was used in drop tests that validated the last portion of the return to Earth phase. As well, Enterprise was used for pad fit tests before an operational shuttle was available.
Columbia flew the first Shuttle orbital flight April 12-14 1981.
Challenger was destroyed on Jan 28, 1986.
The Gemini program ended on Nov 15, 1966, with the landing of the last Gemini mission, Gemini 12, so the Gemini program was long before the Shuttle, and had nothing to do with the Shuttle program. Apollo came after Gemini and before the Shuttle.

Answer:

He needed Guo to design a way to route water to Beijing, which had no natural waterways nearby.

Explanation:

The Kublai Khan (1215-1294) was a Mongol emperor which ruled the Mongol Empire at the height of its power, when it extended from the Pacific coast of Eastern Asia to Central Europe. The Kublai Khan conquered China and established the Mongol Yuan Dynasty, which ruled over it between 1271 and 1368. During this time, the capital of China was established at Khanbaliq, in what would later be known as the city of Beijing. The Kublai Khan dedicated themselves to enlarge it, building a series of large palaces and walls for his capital. The ruler figured out that creating a prosperous city was a necessity, and thus realized that he needed a hydraulic engineer in order to help building his capital. He found one in Guo Shoujing (1231-1316), who since his youth had already become a renowned engineer. The Kublai Khan sent Liu Bingzhong, one of his top architects, and Guo Shoujing to look for a way to route water to Beijing, which had no natural waterways nearby. After a thorough search, Guo came up with a project to build a 30 km long canal from the Baifu springs, in the Shenshan Mountains, to Beijing. This project, which included engineering feats such as a series of water sluices in order to control the flow of water, alleviated Beijing's water problems and provided enough of to irrigate the vast palace gardens. Guo would continue to serve as an engineer to the Kublai Khan and to his successors, and today he's celebrated as a renowned figure in the development of hydraulic engineering and astronomy in China.
