Photos from the Apollo moon program predominate, as well they should-it remains the agency’s crowning achievement. The list omits significant events from space history that were not NASA achievements, such as the famous 1958 photograph of Wernher von Braun and the other architects of the Explorer 1 satellite celebrating their success by holding a model of the satellite over their heads, an event that occurred months before NASA existed. Many wonderful images did not make the final cut-we couldn’t convince the editors to give us 20 pages instead of 10. The rationale for why any one image ranked two slots higher than any other combines several factors, including our attempt to balance the list between human spaceflight, satellite imaging, and planetary exploration. We recognize that any such ranking is inherently subjective. It is expected to make landfall over northern Quang Nam Province, Vietnam, early on September 13.On the occasion of the 50th anniversary of the National Aeronautics and Space Administration, which began its operations on October 1, 1958, we offer this list of the 50 most memorable images from NASA’s history ( see all 50 in the photo gallery below). On September 11, Tropical Storm Conson had weakened to a tropical depression as it tracked northwestward in the South China Sea close to the coast of central Vietnam. The storm was approaching Taiwan, with the center likely remaining just off the eastern coast on September 12 as it makes its way to a landfall on mainland China. Late on September 11, the Joint Typhoon Warning Center advised that Typhoon Chanthu was located about 391 miles (629 km) west-southwest of Kadena Air Base and was tracking north-northeastward. Although Chanthu was a compact system as it passed the Philippines, wind gusts of up to 155 mph (250 km/h) were reported over the islands. Significant wave heights in the open ocean were approaching 14 meters (45 feet). Philippine Standard Time on September 9, the typhoon was about 550 kilometers (300 nautical miles) east-northeast of Manila, with sustained winds of 220 kilometers (140 miles) per hour. NASA’s Earth Observatory states that, according to NOAA scientist Sam Lillo, only five storms on record have intensified at such a rate.īy 11 p.m. Wind speeds accelerated from 50 kilometers (30 miles) per hour to 260 kilometers (160 miles) per hour. Within 48 hours, it had increased to super typhoon strength. Typhoon Chanthu, also called Kiko in the Philippines, first became a tropical depression in the early afternoon on September 6, 2021. Media reports after the passage of the storm reported power outages on the islands but minimal damage. At that time, Tropical Storm Conson was carrying maximum sustained winds of about 59 mph (95 km/h). As the storm moved westward, it made additional landfalls before leaving the islands and entering the West Philippine Sea on September 9. Maximum sustained winds were close to 75 mph (120 km/h) at that time. Late on September 6, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) reported that the storm had rapidly intensified to a typhoon and make landfall in Eastern Samar, Philippines. Tropical Storm Conson, also known as Jolina, first spun up as a tropical depression well east of the Philippines on September 5. The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired this true-color image of the green islands caught between Tropical Storm Conson (west) and Typhoon Chanthu (east). Twin storms flanked the northern Philippines on September 9, 2021, each threatening the islands with strong winds, torrential rains, and dangerous storm surge.
