Ranger 7 Photographs the Moon: 1,000x Closer
Ranger 7 was NASA's first successful lunar probe after six consecutive failures had earned the program the nickname "shoot and hope." On July 31, 1964, the spacecraft plunged toward the Moon at 5,800 mph, transmitting 4,308 photographs in its final seventeen minutes before impact. The last image, taken from just 1,600 feet above the surface, showed details a thousand times sharper than the best Earth-based telescopes could achieve. The photographs revealed a surface covered in craters of all sizes, confirming that the Moon's terrain was rough but manageable for a landing craft. This visual data directly informed the Apollo program's site selection, making manned lunar exploration possible within five years.

Historical Events
Mark Antony controlled the eastern half of the Roman world, commanded a powerful fleet, and had the wealth of Egypt behind him through his alliance with Cleopatra VII. On July 31, 30 BC, his final military gamble at Alexandria produced a brief tactical success before his troops and fleet defected en masse to Octavian's side. Left without an army, Antony stabbed himself with his own sword and was carried, dying, to Cleopatra's monument. His suicide cleared the last obstacle to Octavian's total control of the Roman world. Octavian became Augustus, the first emperor, and transformed the Republic into an autocracy that would endure for five centuries.
The Marquis de Lafayette was nineteen years old, fabulously wealthy, and technically AWOL from the French army when he arrived in America in June 1777 to volunteer for the Revolution. Congress commissioned him a major general on July 31, 1777, though the appointment was initially honorary. Lafayette spent his own money to equip troops, was wounded at Brandywine, endured the winter at Valley Forge alongside his men, and proved himself a capable field commander. More importantly, his presence in America helped convince the French court to commit military and financial support to the Revolution, a decision that ultimately proved decisive. The Franco-American alliance he helped forge led directly to the British surrender at Yorktown.

Samuel Hopkins received U.S. Patent No. 1 on July 31, 1790, for an improved method of making potash and pearl ash, chemicals essential for fertilizer, soap, and glass production. President George Washington signed the patent personally, as did Attorney General Edmund Randolph and Secretary of State Thomas Jefferson. The Patent Act of 1790 had been passed just three months earlier, making the United States one of the first nations to establish a formal system protecting intellectual property. The law reflected the Founders' belief that innovation required economic incentive. Jefferson himself examined early patent applications, though he found the work tedious. The system Hopkins inaugurated now processes over 600,000 applications annually.
The United States and Soviet Union signed the Strategic Arms Reduction Treaty on July 31, 1991, capping each nation at 6,000 nuclear warheads and 1,600 delivery systems. Negotiations had begun under Reagan in 1982 and stalled repeatedly over the Strategic Defense Initiative. The treaty was the most ambitious arms control agreement ever negotiated, requiring the destruction of thousands of warheads under mutual verification. By the time START I was fully implemented in 2001, both sides had reduced their deployed strategic arsenals by roughly 80% from Cold War peaks. The treaty's rigorous verification regime, including on-site inspections and data exchanges, built the institutional trust that made subsequent disarmament agreements possible.
English and Burgundian forces routed a French army at Cravant on the banks of the Yonne River, capturing the French commander and killing thousands of Scottish mercenaries fighting alongside them. The victory secured Burgundy's alliance with England and tightened the noose around the Dauphin's diminishing territory in central France. English dominance of the Hundred Years' War reached its peak in the years following Cravant.
Columbus spotted three peaks rising from the sea and named the island for the Holy Trinity—then spent exactly one day exploring Trinidad before sailing on. July 31, 1498. His crew was exhausted, his ships leaking, and he needed fresh water more than new territory. The indigenous Arawak and Carib peoples had lived there for 7,000 years. Columbus's logbook noted their canoes, their crops, their villages. He claimed it all for Spain in an afternoon. The island became a Spanish colony where, within decades, 40,000 native inhabitants would nearly vanish entirely. Discovery is just another word for interruption.
Maurice, Prince of Orange disbanded the waardgelders militia in Utrecht on July 31, 1618, crushing the political power of the Remonstrants and securing victory for their Counter-Remonstrant rivals. This decisive military move ended years of religious civil strife by removing the armed wing that had protected the dissenting theologians, triggering a complete shift in Dutch governance toward strict Calvinist orthodoxy.
Vilnius fell to 60,000 Russian troops on August 8, 1655, and Tsar Alexei I didn't just occupy the capital—he stayed for six years. The Grand Duchy of Lithuania lost a third of its population during the war, through slaughter, famine, and mass deportation to Russia. Polish-Lithuanian forces recaptured the city in 1661, but found it destroyed: churches looted, archives burned, entire neighborhoods erased. The occupation shattered Lithuania's status as an equal partner in the Commonwealth. What began as Moscow's grab for Ukrainian territory ended up revealing which half of the union could actually defend itself.
The crowd gathered with ammunition. Daniel Defoe stood locked in the pillory at Temple Bar on July 31st, 1703, convicted of seditious libel for his pamphlet mocking Anglican extremism. Standard punishment meant rotten vegetables, stones, dead cats. But Londoners had read "The Shortest Way with Dissenters." They understood satire. Flowers hit his face instead. They drank to his health, guarded him from actual attackers, turned his three-day sentence into a festival. The government had meant to destroy him—they'd made him a hero, and accidentally proved the very point his satire had made about whose side the people were really on.
Twenty-seven Danish warships met sixteen Swedish vessels off Rügen, and after six hours of cannon fire, both fleets simply sailed away. Nobody won. The Danes lost 158 men, the Swedes around 200, but Admiral Gabel didn't pursue the retreating Swedish squadron under Wachtmeister. Both sides claimed victory in their dispatches home. The battle changed nothing—Sweden's Baltic dominance was already crumbling from exhaustion, not defeat. And that's what seventeen years of war looked like by 1712: fleets that couldn't afford to win because losing ships meant losing everything.
Fourteen hundred sailors drowned in a single night when hurricane winds shredded Spain's treasure fleet against Florida's reefs. Eleven ships carrying 14 million pesos in silver and gold—seven years of New World plunder—went down within sight of each other on July 31, 1715. Only the Griffon made it to Spain. Survivors clung to wreckage for days while sharks circled. Spain immediately sent salvage divers who recovered half before abandoning the rest. The scattered coins and jewels sat untouched for 250 years until Kip Wagner found a blackened piece of eight on a beach in 1959. He'd just located the richest shipwreck site in American waters.
Fifty-eight British soldiers marched out of Fort Detroit at 2:30 AM, thinking they'd surprise the Odawa camps. Instead, Chief Pontiac's warriors waited in perfect ambush position along Parent's Creek. Twenty-three redcoats died in the water. The creek ran red for hours—hence the name that stuck. Captain James Dalyell, who'd ignored warnings about the mission, fell in the first volley. His body was left where it dropped. The British stayed trapped inside their fort for five more months, learning that European tactics meant nothing in North American warfare.
Patrick Francis Healy took the helm at Georgetown University on July 31, 1874, shattering racial barriers as the first African American to lead a predominantly white institution. His presidency transformed the school's curriculum and expanded its national reputation, proving that academic excellence transcended the color lines of Reconstruction-era America.
Japanese forces defeated a Russian garrison at Hsimucheng during the Russo-Japanese War, demonstrating the tactical superiority and logistical efficiency that would characterize Japan's campaign in Manchuria. The victory helped secure Japanese control of key supply routes needed for the larger battles to come. The war's outcome shocked Western powers by proving that an Asian nation could defeat a European empire in modern warfare.
