Nixon. <P0-S1> Lano was one of a number of FBI agents who was falsely accused as a source of information for Carl Bernstein and the "Washington Post" during the investigation, which helped shift White House suspicions away from Mark Felt, who was revealed as informant Deep Throat on May 31, 2005. <SEP> <P1-S0> eugene andrew cernan (/ ˈsər. <P1-S1> nən /; march 14, 1934 -- january 16, 2017) was an american astronaut, naval aviator, electrical engineer, aeronautical engineer, and fighter pilot. <P1-S2> during the apollo 17 mission, cernan became the eleventh person to walk on the moon and, as he re-entered the lunar module after harrison schmitt on their third and final lunar excursion, is the last person to have walked on the moon. <SEP> <P2-S0> The astronauts planted a specially designed U.S. flag on the lunar surface, in clear view of the TV camera. <P2-S1> Aldrin remembered, ``Of all the jobs I had to do on the Moon the one I wanted to go the smoothest was the flag raising. <P2-S2> ''But the astronauts struggled with the telescoping rod and could only jam the pole a couple of inches into the hard lunar surface. <P2-S3> Aldrin was afraid it might topple in front of TV viewers. <P2-S4> But he gave`` a crisp West Point salute''. <P2-S5> Before Aldrin could take a photo of Armstrong with the flag, President Richard Nixon spoke to them through a telephone - radio transmission which Nixon called ``the most historic phone call ever made from the White House. <P2-S6> ''Nixon originally had a long speech prepared to read during the phone call, but Frank Borman, who was at the White House as a NASA liaison during Apollo 11, convinced Nixon to keep his words brief, to respect the lunar landing as Kennedy's legacy. <SEP> <P3-S0> the flag that flew during that episode in history became a significant artifact. <P3-S1> it remained in the possession of major armistead, who was promoted to brevet lieutenant colonel, and his family for many years. <P3-S2> eben appleton, colonel armistead's grandson, inherited the flag in 1878. in 1907, he lent it to the smithsonian institution, and in 1912 it was made a formal gift. <P3-S3> today it is permanently housed in the national museum of american history, one of the smithsonian institution museums on the national mall in washington, d.c. the flag was given to the museum in 1912, and has undergone multiple restoration efforts after being originally restored by amelia fowler in 1914. <SEP> <P4-S0> The Smithsonian museums are the most widely visible part of the United States' Smithsonian Institution and consist of nineteen museums and galleries as well as the National Zoological Park. <P4-S1> Seventeen of these collections are located in Washington D.C., with eleven of those located on the National Mall. <P4-S2> The remaining ones are in New York City and Chantilly, Virginia. <P4-S3> As of 2010, one museum, the Arts and Industries Building, is closed in preparation for a substantial renovation, and its newest museum building, the National Museum of African American History and Culture, opened in 2016.
