Here is a question about this article: On the whole, Eisenhower's support of the nation's fledgling space program was officially modest until the Soviet launch of Sputnik in 1957, gaining the Cold War enemy enormous prestige around the world. He then launched a national campaign that funded not just space exploration but a major strengthening of science and higher education. His Open Skies Policy attempted to legitimize illegal Lockheed U-2 flyovers and Project Genetrix while paving the way for spy satellite technology to orbit over sovereign territory, created NASA as a civilian space agency, signed a landmark science education law, and fostered improved relations with American scientists.
What is the answer to this question: What was the name of the civilian space agency created by Eisenhower?
****
So... NASA

Here is a question about this article: In the medieval period the wall circuit was expanded. Via Vittorio Emanuele continued to be the main road east-west through the walled city. West gate was still Porta Nuova, the circuit continued to Corso Alberti, to Piazza Vittorio Emanuele Orlando where it turned east along Via Volturno to Piazza Verdi and along the line of Via Cavour. At this north-east corner there was a defence, Castello a Mare, to protect the port at La Cala. A huge chain was used to block La Cala with the other end at S Maria della Catena (St Mary of the Chain). The sea-side wall was along the western side of Foro Italico Umberto. The wall turns west along the northern side of Via Abramo Lincoln, continues along Corso Tukory. The wall turns north approximately on Via Benedetto, to Palazzo dei Normanni and back to Porta Nuova.
