"NASA is offering a variety of special features to commemorate the 50th anniversary of President Kennedy's address at Rice University in Houston on Sept. 12, 1962. In that famous speech, Kennedy proclaimed, "We choose to go to the moon in this decade," which set the United States on a course of space exploration that we continue to build on today. On Wednesday, NASA Television will air in its entirety a high-quality version of the address at 11:15 a.m. EDT, the same time President Kennedy gave the speech 50 years ago."
"While Kennedy laid out some broader motivations, once we reached the Moon the American human exploration program almost collapsed. It has suffered ever since from a lack of long term purpose beyond maintaining a level of national prestige and technological capability. A long term purpose is not beyond our reach. It is needed to provide necessary focus to our human space efforts. ... I envision President Obama at Rice University on the 50th anniversary of Kennedy's speech, laying out a renewed vision."
