I had the chance to see an advance screening of the movie in Vienna, during a meeting of the UN Committee on the Peaceful Uses of Outer Space and the word that best sums it all up is "WOW". It is wonderful to be able to witness all the work that went into a momentous achievement. There is the great moment we all know, the "one step for a man, a giant leap for mankind" moment. But this movie pays a much-deserved tribute to all those men and women who joined efforts to make this possible. Fantastic.
