請依下文回答第 46 題至第 50 題： An Earth-observation satellite for Taiwan's National Space Organization was launched into orbit from Californiain August 2017. The Formosat-5 satellite lifted off from coastal Vandenberg Air Force Base atop a SpaceX Falcon 9rocket, which successfully landed its first stage on a drone ship floating in the Pacific Ocean as the second stagecontinued on and deployed the satellite. Moments before the first-stage touchdown the video link to the vessel froze, then reappeared and showed therocket standing. Cheers erupted in the SpaceX control room in the Los Angeles suburb Hawthorne. "This is the 15thsuccessful landing of a Falcon 9," said Lauren Lyons, the SpaceX webcast launch commentator. Formosat-5 is the first satellite to be fully designed by Taiwan's space agency and is intended to advance the nation'sspace technology and scientific research while providing global imagery with a wide array of uses ranging from naturalresource studies to disaster management. Planned to operate for five years in low-Earth orbit, about 446 miles (720kilometers) high, its main instrument is a sensor that can produce high-resolution black-and-white and color images. A predecessor satellite, Formosat-2, produced more than 2.5 million images over 12 years of operation before itwore out and was decommissioned a year ago. The landing of the Falcon 9 first stage aboard the drone ship Just Readthe Instructions was the latest in a string of successful recoveries at sea or on shore by SpaceX, which sees reusabilityof major rocket components as key to driving down launch costs. 【題組】 47 According to the passage, what was the primary reason that SpaceX control room cheered at the time?
