  5. On July 16, Nixon issued Proclamation 3919, making Monday, July 21, 1969 a "National Day of Participation." Federal agencies closed and employees were excused, except State, Defense and essential staff. He urged governors, mayors, school heads and private employers to do the same so citizens could "share in the significant events of that day." Source: 34 Fed.

  10. Cause, per NASA's own report: these were "Executive overflow" alarms, meaning the computer couldn't finish all its work in one cycle. Unexpected counter interrupts from the rendezvous radar's coupling data unit were taking up more than 10% of its capacity. Guidance and control "was not affected."

  12. Armstrong took manual control and flew Eagle about 1,100 feet downrange from the planned point in the final 2.5 minutes. (ALSJ: this was to get past the boulder field around West Crater.) Source: MR p. 1-1 (1100 feet; final 2-1/2 minutes); ALSJ Landing commentary after 102:42:41
  13. Fuel callouts: Duke "60 seconds" at 102:45:02 and "30 seconds" at 102:45:31. Both counted down to the "Bingo" (land-or-abort) call, not to an empty tank. Source: ALSJ Landing 102:45:02, 102:45:31 (editorial gloss in the journal)
  14. The descent low-fuel light came on at 102:44:30.4, which indicated about 116 seconds of total firing time left. At engine cutoff the indicated margin was about 45 seconds to propellant depletion (postflight calculation: 50 seconds to oxidizer tank 2 depletion). The land-or-abort decision point was at 20 seconds. Source: MR §9 (Lunar module descent propulsion), pp. 9-23 to 9-24 (ALSJ cites the figure on p. 9-24)
  15. ALSJ's postflight summary: Eagle landed with about 770 lb of fuel. About 100 lb of that was unusable, and the rest was enough for about 45 seconds, including about 20 seconds reserved for an abort. Source: ALSJ Landing commentary (citing MR p. 9-24)

  22. The camera in the descent stage's equipment module (MESA) was deployed from the ladder and gave live TV of Armstrong climbing down. ALSJ (citing the station loop tape): the TV came on upside-down at about 02:54:00 GMT, 10:54 p.m. EDT, and was flipped upright about 31 seconds later.

  25. The famous line, as broadcast and as the papers printed it the next morning: "That's one small step for man, one giant leap for mankind." Armstrong said afterward that he had intended "for a man" and believed he'd said it. The "a" is not convincingly audible in the recordings. ALSJ and TEC now print "(a)" in brackets to honor his intent. Source: ALSJ note after 109:24:23 (citing Chaikin, A Man on the Moon; Ford 2006 analysis and later rebuttals); NYT and Washington Post front pages, July 21, 1969 (both print "for man"); TEC Tape 70/24 p. 377 (HTML rendition shows "(A)") (disputed: the words heard vs)
  26. Armstrong's first description: "Yes, the surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers, like powdered charcoal, to the sole and sides of my boots." Source: ALSJ 109:24:48 (TEC prints "pick it up"; NYT printed "pick it up loosely")
  27. Aldrin came down about 19 minutes later. His words on the surface included "Beautiful view!" and then "Magnificent desolation." (109:43:16, 109:43:24, about 11:15 p.m. EDT) Source: ALSJ One Small Step, 109:43:16 to 109:43:24

  29. The flag went up at about 110:09 (about 11:41 p.m. EDT). The top crossbar's telescoping rod wouldn't fully extend, so the flag stayed partly furled.

  34. The Safire contingency statement: on July 18, 1969, speechwriter William Safire sent H. R. Haldeman a memo titled "IN EVENT OF MOON DISASTER," a statement for Nixon to use if the astronauts were stranded. It begins: "Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace." It was never needed.

  35. The lunar camera (built by Westinghouse) used a non-standard slow-scan format: 10 frames per second and 320 lines. US broadcast TV was 30 frames per second and 525 lines. NASA had budgeted only 500 kHz of bandwidth for TV, against the 4.5 MHz used by commercial TV. Source: The Apollo 11 Telemetry Data Recordings: A Final Report (NASA Goddard, L. Keesey, 2009), p. 3, https://apollojournals.org/alsj/a11/Apollo_11_TV_Tapes_Report.pdf; Broadcasting, July 28, 1969, p. 30 ("320-line slow-scan 10 frames-per-second")
  36. Because broadcasters couldn't air slow-scan, RCA-built scan converters at the receiving sites re-shot the picture into standard US format. It was then sent by microwave, Intelsat satellites and AT&T landlines to Houston, and from there to the networks. Each step degraded the image. That is why viewers saw "blurry, ghostlike images" while station engineers saw a crisp picture on slow-scan monitors.

  37. Three stations received the moonwalk TV: Goldstone, California, and Honeysuckle Creek and Parkes in Australia. MR: primary coverage came from the 210-ft antennas at Goldstone and Parkes, with backup from the 85-ft antennas at Goldstone and Honeysuckle Creek. Source: MR §6, p. 6-3; NASA TV Tapes Report p. 4
  38. Houston first used Goldstone's picture (upside down at first, then a poor image), switched to Honeysuckle Creek at about 1:42 into the broadcast, before the first step, then went back and forth. Armstrong's first step went out on Honeysuckle Creek's picture. At about 8:53 into the broadcast (03:02:53 GMT, 11:02 p.m. EDT), Houston switched to Parkes and stayed with it for the rest of the 2.5-hour moonwalk.

  40. Why Parkes wasn't on the air for the step: the moonwalk started hours early. Broadcasting (1969) explains that Parkes had been scheduled to take all the TV because Australia would face the Moon at the planned 2 a.m. EDT time. CSIRO adds that the Moon was still rising at Parkes, and the main detector didn't have it in view until about 8.5 minutes into the broadcast. Before that, Parkes used a less sensitive off-axis detector. Source: Broadcasting, July 28, 1969, p. 30; CSIRO Apollo 11 page; Sarkissian 2001 abstract
  41. Parkes worked through a violent windstorm. Sarkissian describes "a violent squall" buffeting the dish beyond its safety limits. CSIRO says gusts reached about 100 km/h.

  46. Nielsen, as reported Sept. 1969: The Apollo 11 mission (July 16 to 24) "drew the largest television audience ever, according to A. C. Nielsen Co." An estimated 53.5 million TV households, 93.9% of all US TV households, each watched an average of 15 hours 35 minutes of sponsored network coverage from July 14 to July 27.

  47. Same Nielsen report: the share of households watching JFK's assassination and funeral coverage in 1963 was higher, 96.1%, but that was fewer homes, 49.4 million, each averaging 31 hours 38 minutes. The 1968 Democratic convention drew 50.5 million homes (90.1%). Source: Broadcasting, Sept. 1, 1969, p. 50
  48. Same Nielsen report, the night itself: the greatest increase over normal viewing came during the moonwalk, 11 p.m. July 20 to 1 a.m. July 21, when TV-using households rose 99%, from 25.1% to 49.9%. The greatest number of homes, 61.1%, watched during the walk-up, 7 to 11 p.m. July 20. The landing period (noon to 5 p.m. July 20) showed a 79% increase, and the launch (July 16, 7 a.m. to noon) a 75% increase. Source: Broadcasting, Sept. 1, 1969, p. 50

  60. On Tuesday, July 15, 1969, the eve of the launch, the Rev. Ralph D. Abernathy (SCLC) brought about 150 poor Black Southerners, "mostly children and their mothers" (25 families, UPI says), to a field near the Kennedy Space Center to protest "a distorted sense of national priorities." NASA Administrator Thomas O. Paine met them and said: "If it were possible for us not to push that button tomorrow morning and solve the problems you are talking about, we would not push that button." Paine gave Abernathy 10 VIP launch passes. Abernathy said he was "profoundly moved by the nation's achievements in space and the heroism of the three men." Signs read "billions for space, pennies for hunger."

  61. Neil Armstrong's mother, Viola, in Wapakoneta, Ohio: "I was worried that the moon might be too soft and that he would sink in too deeply. But I'm so thankful they got there safely."

  65. The early-moonwalk decision. At GET 104:39:14 (6:11 p.m. EDT, 5:11 p.m. Houston time, Sunday, July 20) the crew radioed: "Our recommendation at this point is planning an EVA, with your concurrence, starting about eight o'clock this evening, Houston time. That is about 3 hours from now." At 104:39:40 (6:11 p.m. EDT) CapCom Charlie Duke replied: "We thought about it; we will support it." Duke added: "You guys are getting prime time TV there." At 104:40 Armstrong clarified that eight o'clock Houston time (9 p.m. EDT) meant hatch opening. The scheduled rest period was due to begin at 104:50 (Aldrin, 1969 Technical Debrief). In the event, EVA prep began at 106:11:14 (7:43 p.m. EDT), and the first step came at 10:56 p.m. EDT.

Afterward: New York City gave the crew a ticker-tape parade on Wednesday, Aug. 13, 1969, up Broadway (renamed "Apollo Way" for the day) to City Hall, the first stop of a one-day tour that also took in Chicago and Los Angeles. Crowd figures, as reported at the time: the city's Public Events Commissioner, John S. (Bud) Palmer, called the street crowd "the biggest ever in the history of New York" and put it at four million. The NYT called that "a figure hallowed by tradition," used for Lindbergh (1927) and Glenn (1962), and wrote that "experienced observers said that those receptions had undoubtedly exceeded" this one. UPI estimated "two million New Yorkers glimpsed the lunar explorers." The motorcade ran more than half an hour ahead of schedule, so many people missed it.
