The Apollo 11 crew, Buzz Aldrin, Neil Armstrong, and Michael Collins, who had not appeared publicly since the 5th anniversary, participated in ceremonies in Washington, D.C., on July 20, 1979.[2] On the 20th anniversary in 1989, President George H. W. Bush announced plans to return to the Moon and then to Mars, known as the Space Exploration Initiative (SEI).[4] The stamp, named "Man Walks on Moon", is Scott catalogue number 3188e, and depicts Aldrin's lunar bootprint.[27] From July 16 to 24, 2009, NASA streamed the original mission audio on its website in real time 40 years to the minute after the events occurred.[29] In July 2010, air-to-ground voice recordings and film footage shot in Mission Control during the Apollo 11 powered descent and landing was re-synchronized and released for the first time.[30] The John F. Kennedy Presidential Library and Museum set up an Adobe Flash website that rebroadcasts the transmissions of Apollo 11 from launch to landing on the Moon.[34][35] A group of British scientists interviewed as part of the anniversary events reflected on the significance of the Moon landing: It was carried out in a technically brilliant way with risks taken ... that would be inconceivable in the risk-averse world of today ...The three day (July 18 to 20, 2019) outdoor festival featured hands-on exhibits and activities, live performances, and speakers such as Adam Savage and NASA scientists.[46][47] On July 19, 2019, the Google Doodle paid tribute to the Apollo 11 Moon Landing, complete with a link to an animated YouTube video with voiceover by astronaut Michael Collins.[50] Trump had also honored Aldrin, Gene Kranz, and the Apollo 11 mission in the 2019 State of the Union Address and the 2019 Salute to America event at the National Mall.
