Today's Wisdom - Time, Rackets and NASA

Welcome back to A Little Wiser. Thanks to everyone who continues to support the newsletter, please feel free to reply with a lesson you’d like to see soon! Today’s wisdom explores:

Grab your coffee and let’s dive in.

If you took a train from New York to Chicago in 1870, you would pass through over 20 different time zones, each one based on when the sun reached its highest point in that particular town. Buffalo ran 12 minutes behind New York. Cleveland was 19 minutes behind Buffalo. Toledo had its own time, as did Detroit, and Gary, Indiana. By the time you arrived in Chicago, your pocket watch would be useless unless you'd been constantly resetting it at every station, and even then, you'd have no idea what time it actually was because there was no standardized "actual time" to reference. Every town in America operated on "local solar time," which meant noon was the moment the sun was directly overhead, and since that moment happens at slightly different times depending on your longitude, every city had its own unique time. This worked fine when travel was slow and communication was local, but once railroads started moving people across hundreds of miles in a single day, the system collapsed into chaos.

The man who solved this mess was a railroad engineer named William F. Allen, who in 1883 proposed dividing the United States into four time zones, each exactly one hour apart. On November 18, 1883, known as "The Day of Two Noons," railroads across America synchronized their clocks to the new system at precisely noon, and suddenly the country operated on a unified standard. After the 1884 International Meridian Conference, countries gradually adopted a global system of roughly 24 time zones, each about 15 degrees of longitude wide, with Greenwich, England serving as the prime meridian where time begins. The logic was elegant: Earth rotates 360 degrees in 24 hours, so every 15 degrees you travel east or west, the time shifts by one hour.

The reality, of course, is far messier than the theory. China, despite spanning five geographic time zones, uses only one, Beijing Time, across the entire country, which means the sun rises at 10am in western regions. Spain sits in the same longitude as the UK but uses Central European Time because Franco aligned with Nazi Germany during World War II and never changed it back. India and Nepal use half-hour offsets, while some regions like the Chatham Islands use 45-minute offsets, creating time zones that don't fit the neat one-hour grid. The strangest case is Kiribati, a Pacific island nation that sits on both sides of the International Date Line and had to choose whether to be 12 hours ahead or 12 hours behind neighboring countries, so in 1995, they just moved the Date Line to loop around them, creating a time zone that's +14 hours from UTC, the furthest ahead on Earth. Time zones were invented to fix the chaos of local solar time, but they've created their own kind of chaos, a patchwork of political decisions, historical accidents, and compromises that remind us that even something as objective as time is ultimately just a social agreement we've all decided to follow.

If you walk past a public tennis court in America today, there's a good chance it's been painted over with smaller courts for a sport that didn't exist in any meaningful way 20 years ago. Pickleball, a game that combines tennis, badminton, and ping-pong, has become the fastest-growing sport in the United States, with over 20 million Americans now playing regularly. Meanwhile, in Europe and Latin America, padel, a sport that looks like tennis played inside a glass box, has exploded to over 35 million players worldwide, with professional tournaments drawing crowds that rival traditional tennis. The shift represents a fundamental change in how people want to play racket sports.

The evolution from real tennis to modern tennis reveals how sports adapt to survive. Real tennis, played in French monastery cloisters as early as the 12th century, was a game for monks who hit balls with their bare hands before adding gloves and eventually paddles. By the 16th century, it had become the sport of kings, played by Henry VIII and Louis X of France in purpose-built indoor courts with absurdly complex rules involving sloped roofs, irregular walls, and galleries where the ball could land for points. The scoring system made no sense, matches could last hours, and building a court cost a fortune, which is why only about 50 real tennis courts still exist worldwide. Modern lawn tennis emerged in 1873 when British Major Walter Clopton Wingfield patented a simplified outdoor version called "Sphairistikè," designed to be played on croquet lawns by the middle class who couldn't afford indoor palaces. Wingfield's genius was stripping away the architectural complexity and creating a game that only required a net, a grass rectangle, and rackets. The All England Croquet Club in Wimbledon was struggling financially and decided to host a tennis tournament in 1877 to raise money, and the sport exploded. Within a decade, real tennis was a relic and lawn tennis was being played worldwide.

The new wave follows the same pattern of simplification. Pickleball was invented in 1965 when Congressman Joel Pritchard returned from golf to find his family bored, so they improvised using a badminton court, ping-pong paddles, and a perforated plastic ball, naming it after Pritchard's dog, Pickles, who kept stealing the ball. The rules are designed for instant gratification: you serve underhand diagonally, and there's a no-volley zone near the net called "the kitchen" where you can't smash the ball, forcing finesse over power. Games go to 11 points, rallies are fast, and beginners can compete within an hour. Padel, invented in Mexico in 1969, encloses the court with glass walls so the ball bounces back into play like squash, making rallies last longer and reducing the frustration of chasing balls into the parking lot. Serves must be underhand and below waist height, eliminating the punishing 120 mph serves that make recreational tennis miserable for amateurs. The pattern is consistent: racket sports spent centuries getting faster, more technical, and more exclusive, requiring specialized courts and years of practice. Pickleball and padel succeeded by doing the opposite, building sports that anyone can play immediately without destroying their knees or their dignity.

2026 might represent the biggest leap in space exploration since the Apollo era. NASA plans to launch the Artemis II mission on the Space Launch System sending astronauts around the Moon on a ten-day lunar flyby in early 2026, the first crewed lunar flyby since the Apollo program. Four astronauts, Commander Reid Wiseman, pilot Victor Glover, payload specialist Christina Koch, and mission specialist Jeremy Hansen, will become the first humans to leave low Earth orbit since December 1972. They won't land on the Moon, that's saved for Artemis III in 2027, but they'll fly farther from Earth than any human has traveled in over half a century, testing the hardware that will eventually establish a permanent lunar presence.

In fact, the Moon is about to get crowded with visitors. In early 2026, NASA and Blue Origin plan to launch Blue Moon Pathfinder Mission, the first uncrewed mission of the Blue Moon Mark 1 intended to test various technologies needed for future crewed Lunar landers. Firefly Aerospace is sending its Blue Ghost Mission 2 to the far side of the Moon in late 2026, carrying the first operational radio telescope that will ever sit on the lunar surface. Astrobotic is launching its massive Griffin lander in July, capable of carrying significantly more cargo than any previous commercial mission. China isn't sitting out either, the country plans to launch Chang'e 7 to explore the lunar south pole in late 2026. All of these missions are racing to the same goal: finding water ice near the lunar poles, which could be converted into rocket fuel and drinking water, making long-term lunar habitation actually feasible. The Moon is transitioning from a destination we visit occasionally to a place we're preparing to stay.

But NASA's ambitions extend far beyond the Moon. In September, NASA plans to launch the Nancy Grace Roman Space Telescope, an infrared space telescope for cosmology and search for exoplanets. What makes Roman special is how much sky it can see at once. Its 300-megapixel camera captures regions about 100 times larger than Hubble's field of view while maintaining comparable sharpness, allowing it to survey billions of galaxies and discover over 100,000 distant exoplanets during its five-year mission. Meanwhile, ESA's Hera spacecraft is expected to arrive at the double asteroid Didymos in November to study the aftermath of NASA's 2022 DART impact that successfully altered an asteroid's orbit, testing our ability to defend Earth from future impacts. The year nearly went very differently. In May 2025, the Trump administration proposed cutting NASA's which would have canceled the Space Launch System and Orion spacecraft after Artemis III, but Congress intervened in July, allocating $10 billion that saved the program and funded missions through 2030. NASA is operating on borrowed political will, and 2026 might be the year that determines whether humanity's return to deep space is a brief revival or the beginning of something permanent.
