Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945), often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. A member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which realigned American politics into the Fifth Party System and defined American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II, which ended shortly after he died in office. He is usually rated by scholars among the nation's greatest presidents, after George Washington and Abraham Lincoln, but has also been subject to substantial criticism.

NASA's Explorer 49 (also called Radio Astronomy Explorer-B(RAE-B)) was a 328-kilogram (723 lb) satellite launched on June 10, 1973 for long wave radio astronomy research. It had four 230-metre-long (750 ft) X-shaped antenna elements, which made it one of the largest spacecraft ever built.
Explorer 49 was launched after the termination of the Apollo program, and although it did not examine the Moon directly, it became the last American lunar orbital mission until the launch of Clementine spacecraft in 1994. It was launched on June 10, 1973, 14:13:00 UTC in the Rocket Delta 1913 from the Launch site Cape Canaveral LC-17B.
This mission was the second of a pair of Radio Astronomy Explorer (RAE) satellites, Explorer 38 or RAE-A being the first. Explorer 49 was placed into lunar orbit to provide radio astronomical measurements of the planets, the Sun, and the galaxy over the frequency range of 25 kHz to 13.1 MHz. Since the spacecraft's design used gravity gradient booms, the lumpy lunar gravity field was a problem for the mission scientists.
