July 20th
On the afternoon of July 20, 1969, the lunar module Eagle separated from the command ship Columbia and began falling toward the Moon with Neil Armstrong and Buzz Aldrin aboard. Almost immediately, things started going wrong. Partway through the descent, a shrill alarm sounded in the cabin — “Program alarm… it’s a 1202,” Armstrong called down, in a voice flight controllers later described as the closest to rattled they’d ever heard him. Nobody in the spacecraft knew what a 1202 was. In Houston, a 26-year-old guidance officer and his back-room expert had seconds to decide whether to abort the landing of the century. Their verdict: the computer was overloaded but still flying the ship. “We’re GO on that alarm.” The descent continued — with the alarms blaring again and again, five times in four minutes.
Then Armstrong looked out the window and saw the next problem: the computer was steering them straight into a crater the size of a football field, rimmed with boulders as big as cars. He took over manual control and did something no simulation had fully prepared anyone for — he flew the lunar module like a helicopter, skimming across the gray surface, hunting for a clear patch while his fuel ran out beneath him. In Houston, the only voice on the loop was the fuel callout: “Sixty seconds.” Then: “Thirty seconds.” By the most common accounting, Eagle touched down with roughly 25 seconds of usable fuel left before a mandatory abort. Armstrong keyed his mic: “Houston, Tranquility Base here. The Eagle has landed.” Capcom Charlie Duke’s reply said it all: “Roger, Tranquility, we copy you on the ground. You got a bunch of guys about to turn blue. We’re breathing again.”
What most people forget is what happened next: nothing. For more than six hours, the two men just sat in the cramped cabin on the surface of the Moon — running through checklists, rehearsing an emergency liftoff, eating a meal. During that quiet stretch, Aldrin, an elder at his Presbyterian church back in Texas, unpacked a tiny kit his congregation had given him and privately took communion — a sip of wine and a piece of bread, the first food and drink ever consumed on another world. He kept it off the radio; NASA was gun-shy about broadcast religion after being sued over Apollo 8’s Genesis reading. In the Moon’s gentle one-sixth gravity, he later wrote, the wine curled slowly and gracefully up the side of the cup.
Finally, at 10:56 p.m. Eastern time — with an estimated 600 million people watching the ghostly TV picture — Armstrong backed down the ladder and put his boot into the powder of the Sea of Tranquility: “That’s one small step for man, one giant leap for mankind.” But the men in Mission Control will tell you the real drama had already happened hours earlier — in those five blaring alarms, that boulder field, and the twenty-five seconds between the Eagle and going home empty-handed.
Also On This Day…
1944 — The Briefcase That Almost Killed Hitler On July 20, 1944, German colonel Claus von Stauffenberg walked into a briefing at Hitler’s “Wolf’s Lair” headquarters, set down a briefcase packed with explosives a few feet from the Führer, and excused himself to take a phone call. Minutes later the bomb tore the room apart — but an officer had nudged the briefcase behind a heavy oak table support, and Hitler stumbled out with shredded trousers, a burst eardrum, and his life. The plot to seize Germany, code-named Valkyrie, collapsed by midnight. Stauffenberg was executed by firing squad, and in the purge that followed, thousands of suspected conspirators were arrested and executed. The war would grind on for nine more months.
1968 — The First Special Olympics Opens in Chicago On July 20, 1968, about a thousand athletes with intellectual disabilities marched into Soldier Field in Chicago for the first-ever Special Olympics — an event dreamed up by Eunice Kennedy Shriver, who had started it all with a summer day camp in her own backyard. At a time when many of the athletes were expected to live their whole lives in institutions, they swam, ran, and played floor hockey before cheering crowds. Today the Special Olympics serves millions of athletes in more than 190 countries — and it all traces back to that one July day on the Chicago lakefront.
1976 — Viking 1 Lands on Mars, Seven Years to the Day NASA has a thing about July 20. Exactly seven years after the Eagle landed, the Viking 1 lander dropped through the pink Martian sky and settled onto the rocky plain of Chryse Planitia — America’s first successful landing on Mars. The touchdown was originally scheduled for July 4, 1976, as a Bicentennial spectacular, but orbital photos showed the landing site was dangerously rough, so engineers delayed and moved it. Minutes after touchdown, Viking 1 radioed home the first photograph ever taken from the surface of Mars: its own footpad, planted in red dirt.
1976 — Hank Aaron’s Last Home Run That very same day, in Milwaukee, 42-year-old Hank Aaron got around on a pitch from Dick Drago of the California Angels and sent it over the fence at County Stadium. It was home run number 755 — the last of his career, and the number that stood as baseball’s all-time record for more than three decades. Nobody in the ballpark that Tuesday night could know they’d just seen the final swing of one of the greatest runs in sports history: 23 seasons, 755 home runs, and not one of them cheap.
1985 — “Today’s the Day”: The Atocha Treasure Is Found For 16 years, treasure hunter Mel Fisher had searched the waters off Key West for the wreck of the Nuestra Señora de Atocha, a Spanish galleon that sank in a 1622 hurricane loaded with New World silver and gold. Every morning he told his crew the same thing: “Today’s the day.” On July 20, 1985, it finally was — his divers found the “mother lode,” a reef of silver bars, gold, and emeralds valued at roughly $450 million. The find cost Fisher dearly along the way, including a son and daughter-in-law lost in the search, but it remains one of the richest shipwreck recoveries ever made.
Alarms blaring over the Moon, a briefcase under Hitler’s table, a footpad in Martian dirt, one last swing in Milwaukee, and a reef of Spanish silver off Key West — July 20th is the day history holds its breath, and then exhales.
