We lost a true legend this week with the passing of NASA astronaut Jim Lovell at the ripe old age of 97. Lovell commanded the ill-fated Apollo 13 mission back in 1970, and along with crewmates Jack Swigert and Fred Haise — along with just about every person working at or for NASA — he managed to guide the mortally wounded Odyssey command module safely back home. While he’s rightly remembered for the heroics on 13, it was far from his first space rodeo. Lovell already had two Gemini missions under his belt before Apollo came along, including the grueling Gemini 7, where he and Frank Borman undertook the first long-duration space mission, proving that two men stuffed into a Volkswagen-sized cockpit could avoid killing each other for at least two weeks.

This week, we witnessed a couple of space oopsies as both Starship and New Glenn suffered in-flight mishaps on the same day. SpaceX’s Starship was the more spectacular, with the upper stage of the seventh test flight of the full stack experiencing a “rapid unscheduled disassembly” thanks to a fire developing in the aft section of the stage somewhere over the Turks and Caicos islands, about eight and a half minutes after takeoff from Boca Chica. The good news is that the RUD happened after first-stage separation, and that the Super Heavy booster was not only able to safely return to the pad but also made another successful “chopsticks” landing on the tower. Sorry, that’s just never going to get old.

On the Bezos side of the billionaire rocket club, the maiden flight of Blue Origin’s New Glenn ended with the opposite problem. The upper stage reached orbit, but the reusable booster didn’t make it back to the landing barge parked off the Bahamas. What exactly happened isn’t clear yet, but judging by the telemetry the booster was coming in mighty fast, which may indicate that the engines didn’t restart fully and the thing just broke up when it got into the denser part of the atmosphere.

Esperanto: The Language That Hoped To Unite The World

December 25, 2024 by Heidi Ulrich 65 Comments

Christmas: a good time to broach a topic of hope. We’re talking Esperanto. This language that spurred the hope it one day could hack the barriers between people, eliminating war and miscommunication. The video below unpacks the history of this linguistic marvel. Esperanto was a constructed language dreamed up in 1887 by Ludwik Zamenhof, a Polish-Russian eye doctor with a knack for linguistics and great ideals. If you’re a little into linguistics yourself, you’ll sure know the name stems from the Latin sperare: to hope.

Inspired by the chaos of multilingual strife in his hometown, Zamenhof created Esperanto to unite humanity under a single, simple, easy-to-learn tongue. With just 16 grammar rules, modular word-building, and no pesky exceptions — looking at you, English — Esperanto was a linguistic hack ahead of its time.

But Esperanto wasn’t just a novelty—it almost became the lingua franca of diplomacy. In 1920, Iran proposed Esperanto as the official language of the League of Nations, but the French vetoed it, fearing their language’s global dominance was at risk. From there, Esperanto’s journey took a darker turn as both Nazi Germany and Stalinist Russia persecuted its speakers. Despite this, Esperanto persisted, surfacing in quirky corners of culture, from William Shatner’s Esperanto-only horror film Incubus to its inclusion on NASA’s Voyager Golden Record.

Fast-forward to the digital age: Esperanto is thriving on online learning platforms, where over a million learners explore its minimalist elegance. It appears at places in various editions of Grand Theft Auto. It has even inspired modern makers to create new constructed languages, like Loglan, Toki Pona, and even Klingon. Could Esperanto—or any reimagined language—rise again to unite us? For curious minds, watch the video here.

It may be hard to believe, but BASIC turned 60 this week. Opinions about the computer language vary, of course, but one thing everyone can agree on is that Professors Kemeny and Kurtz really stretched things with the acronym: “Beginner’s All-Purpose Symbolic Instruction Code” is pretty tortured, after all. BASIC seems to be the one language it’s universally cool to hate, at least in its current incarnations like Visual Basic and VBA. But back in 1964, the idea that you could plunk someone down in front of a terminal, or more likely a teletype, and have them bang out a working “Hello, world!” program with just a few minutes of instruction was pretty revolutionary. Yeah, line numbers and GOTO statements encouraged spaghetti code and engrained bad programming habits, but at least it got people coding. And perhaps most importantly, it served as a “gateway drug” into the culture for a lot of us. Many of us would have chosen other paths in life had it not been for those dopamine hits provided by getting that first BASIC program working. So happy birthday BASIC!

HOPE Is On, Spread The Word

Since 1994, Hackers on Planet Earth (HOPE) has been on the short list of must-see hacker events in the United States. Held in New York every other year (global pandemics notwithstanding), it’s an event where hackers, makers, artists, and luminaries can meet and swap ideas into the wee hours of the morning. With hands-on demonstrations, art installations, an incredible roster of speakers, and all the Club-Mate you can drink, there really is something for everyone.

Tickets are now available for HOPE XV, which will be held from July 12th to the 14th in Queens. It will once again be held on the campus of St. John’s University, as the historic Hotel Pennsylvania which played host to the con since its inception was converted into a somewhat less luxurious empty lot in 2022.

Webb’s first deep-field image. Source: NASA

The folks at NASA are taking a well-deserved victory lap this week after the splashy reveal of the first scientific images from the James Webb Space Telescope. As we expected, the first public release included a lot of comparisons to images obtained from Hubble, as the general public understandably sees Webb as the successor to the venerable space telescope, now in its third decade of service. So for a “let’s see what this baby can do” image, they turned Webb loose on a tiny patch of sky in the southern hemisphere containing galactic cluster SMACS 0723, and sent back images and spectroscopic data from galaxies up to 13 billion light years away. There are plenty of analyses of Webb’s deep field and the other images in the first release, but we particularly liked the takes by both Anton Petrov and Dr. Becky. They both talk about the cooler scientific aspects of these images, and how Webb is much more than just a $10 billion desktop image generator.

If you need evidence that our outwardly peaceful little neck of the solar system is actually a dangerous place, look no further than the 40 newly launched Starlink satellites that were just clobbered out of orbit. It seems that the SpaceX launch on February 3 was ill-timed, as it coincided with the arrival of energetic plasma from a solar storm that occurred a few days before. The coronal mass ejection followed an M-class flare on the Sun, which was aimed just right to hit just as the 49-satellite addition to the Starlink constellation was being released. This resulted in an expansion of the upper atmosphere sufficient to increase drag on the newborn satellites — up to 50% more drag than previous launches had encountered. Operators put the satellites into safe mode, but it appears that 40 of them have already met a fiery demise, or soon will. Space is a tough place to make a living.
