Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Württemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Württemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenführer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Müller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswärtiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadeführer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

Question: On what date did Apollo 11 land at it's destination site? Passage: are three views of Mare Tranquillitatis on the Moon, taken by the mapping camera of the Apollo 17 mission in 1972, facing south-southwest from an average altitude of 111 km on Revolution 36 of the mission. At the left is the east side of Mare Tranquillitatis, with the craters Franz (bottom right), Lyell (dark floor, right of center), and Taruntius (upper left). The "bay" of dark mare (basalt) at left is Sinus Concordiae, with "islands" of older, light highland material. At the right is the crater Cauchy, which lies between the Rupes Cauchy and Cauchy rille. The center photo shows the central mare with craters Vitruvius (lower right) and Gardner (bottom center). At the horizon are lighter highlands at the southern margin of the mare, near the Apollo 11 landing site. The crater Jansen is visible at the edges of both the center and right photos. The right photo shows the western mare, with the craters Dawes (lower left) and the large Plinius (43 km diameter), with the Plinius Rilles in the foreground. These photos were taken within minutes of each other as the command module America orbited the Moon. The Sun elevation drops from 46 degrees at left to 30 degrees at right.
