1999 - Chandra X-Ray Space Telescope, launched on July 23, 1999,  reveals previously unobserved features in the remnants of three different supernova explosions.

1963 - President John F. Kennedy addresses the United Nations General Assembly and suggests the possibility of Russian-American "cooperation" in space. Kennedy stated that, "in a field where the United States and the Soviet Union have a special capacity - the field of space - there is room for new cooperation, for further joint efforts in the regulation and exploration of space. I include among these possibilities," he said, "a joint expedition to the moon. . . . Surely we should explore whether the scientists and astronauts of our two countries - indeed, of all the world - cannot work together in the conquest of space, sending some day in this decade to the moon, not the representatives of a single nation, but the representatives of all humanity."
