After the Soviet Union launched the world's first artificial satellite in 1957, Eisenhower authorized the establishment of NASA, which led to the space race. During the Suez Crisis of 1956, Eisenhower condemned the Israeli, British and French invasion of Egypt, and forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. In 1958, Eisenhower sent 15,000 U.S. troops to Lebanon to prevent the pro-Western government from falling to a Nasser-inspired revolution. Near the end of his term, his efforts to set up a summit meeting with the Soviets collapsed because of the U-2 incident. In his January 17, 1961 farewell address to the nation, Eisenhower expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, and coined the term "military–industrial complex".
On what date did Eisenhower deliver his presidential farewell address?
January 17, 1961

All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds. These two subdivisions are often given the rank of superorder, although Livezey and Zusi assigned them "cohort" rank. Depending on the taxonomic viewpoint, the number of known living bird species varies anywhere from 9,800 to 10,050.
What is another name for Aves?
Neornithes

Paul VI did away with much of the regal splendor of the papacy. He was the last pope to date to be crowned; his successor Pope John Paul I replaced the Papal Coronation (which Paul had already substantially modified, but which he left mandatory in his 1975 apostolic constitution Romano Pontifici Eligendo) with a Papal Inauguration. Paul VI donated his own Papal Tiara, a gift from his former Archdiocese of Milan, to the Basilica of the National Shrine of the Immaculate Conception in Washington, DC (where it is on permanent display in the Crypt) as a gift to American Catholics.
What ceremony had Paul VI left in place in in the 1975 apostolic constitution?
Papal Coronation
