Question: What was the first award that Iron Maiden received from the Metal Hammer Golden Gods Awards? Passage:In 1994, one of their singles, "Fear of the Dark", received a Grammy nomination for Best Metal Performance. Seven years later, the band were nominated again in that category, with the song "The Wicker Man". In 2011, Iron Maiden won the award with "El Dorado". In 2002, they won the Ivor Novello Award for international achievement. Iron Maiden received a nomination from the Kerrang! Awards in the "Best Live Act" category in 2003, and were inducted into the Kerrang! Hall of Fame two years later. At the 2006 Metal Storm Awards, A Matter of Life and Death was named the best heavy metal album of the year. Iron Maiden have also received nine awards from fourteen nominations at the Metal Hammer Golden Gods Awards. Their mascot Eddie, who has previously been used by US critics to argue that Iron Maiden are Satanists, received a Golden Gods nomination in 2006, losing to singer Cristina Scabbia; but was awarded in 2008. Later in 2008, Iron Maiden were nominated in the Best Live Return category at the Vodafone Live Music Awards, to which the band disagreed with their nomination and asked to be withdrawn, stating that they were "not quite sure where we are returning from." They were replaced by the band James. The band were named "Best British Live Act" at the 2009 BRIT Awards, winning via a public poll. They were not able to attend the ceremony, ironically due to touring duties, instead delivering an acceptance message by video link-up. Their film  won, in the category "24 Beats Per Second", at the SXSW film Festival, held in Austin, Texas, in March 2009. Overall, Iron Maiden have received twenty-nine awards from thirty-nine nominations.

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.
