July 19: Screw Propellers, Tour de France & Waving at Saturn

July 19 is one of those dates that just refuses to sit still — it launched ships, launched bicycle races, and even convinced people to wave at a planet. Let's take a lap around history, ideally at a Tour-de-France pace.

Engineering, Cycling, and a Frankly Huge Boat

Back in 1843, the SS Great Britain slid into the water in Bristol as the first ocean-going ship with both an iron hull and a screw propeller. Translation: it was the fancy new gadget of its day, the maritime equivalent of the first phone with a good camera.

Then in 1903, French cyclist Maurice Garin pedaled his way into legend by winning the very first Tour de France. No carbon-fiber frames, no aerodynamic helmets — just a mustache, a heavy bike, and enough stamina to make the rest of us feel bad about walking to the fridge.

The Day We All Waved at a Planet

In 2013, NASA's Cassini spacecraft snapped a photo of Saturn with a tiny distant Earth in the frame, and people were officially invited to "wave at Saturn." Yes, humanity collectively stepped outside and waved at a gas giant roughly 900 million miles away. Did Saturn wave back? Unclear. But the vibes were immaculate, and honestly it's the most wholesome group activity our species has ever attempted.

Happy Birthday to a Very Familiar Face

Sharing this date is James Austin Johnson, born in 1989 — the American actor and comedian best known for his uncanny presidential impressions on "Saturday Night Live." If you've ever watched someone nail a rambling political monologue so precisely that you forgot it was a bit, that's the man. Also celebrating are athletes like ice hockey's Zach Werenski (1997) and baseball's Patrick Corbin (1989), because July 19 clearly produces people with excellent hand-eye coordination and a healthy fear of losing.

A Holiday Worth Marking

Over in Nicaragua, July 19 is Sandinista Day, also known as Liberation Day — a genuine national observance complete with celebrations and civic pride. So while some of us are busy waving at Saturn, an entire country is marking a serious milestone in its history. Balance, as always.

All told, July 19 gave us a groundbreaking ship, a groundbreaking bike race, a spacecraft photobombing Earth, and a comedian who can imitate anyone. Not a bad day's work for a random square on the calendar. Go outside later — you never know which planet might be watching.
