EDWARDS, Calif. -- Space shuttle Discovery and its crew of seven astronauts ended a 14-day journey of more than 5.7 million miles with an 5:53 p.m. PDT landing Friday at Edwards Air Force Base in California.

The mission, designated STS-128, delivered two refrigerator-sized science racks to the International Space Station. One rack will be used to conduct experiments on materials such as metals, glasses and ceramics. The results from these experiments could lead to the development of better materials on Earth. The other rack will be used for fluid physics research. Understanding how fluids react in microgravity could lead to improved designs for fuel tanks, water systems and other fluid-based systems.

Mission Control has decided to target Edwards Air Force Base, Calif., for today's landing since the weather at Kennedy is unstable. The deorbit burn is timelined to begin at 7:47 p.m. EDT for an 8:53 p.m. landing at Edwards. The burn lasts three to four minutes, slowing Discovery enough to begin its descent
