Someone could go to school for 4 years and study aerospace engineering, then get a PhD with a dissertation related to orbital mechanics, and some instagram influencer who watched a youtube video will be like "actually that guy is wrong" on a topic related to space travel and people will believe them. I'm not sure how we got here, but I hope we go back to a society where credibility is earned with rigorous training in the associated field, not by a popularity contest.

1969. NASA spent $355 million to put two men on the moon. The flag cost $5.50. And three months before launch, nobody at NASA had even thought to bring one. Congress started asking why the biggest space mission ever wouldn’t include an American flag. NASA scrambled. They handed the job to an engineer named Jack Kinzler, a guy everyone at the space center called “Mr. Fix It.” His problem was strange: there’s no air on the moon. No air means no wind. A normal flag would just hang there like a wet towel on a stick. So Kinzler thought back to watching his mom hang curtains as a kid. He designed a metal rod that slid through the top of the flag like a curtain rod, holding the fabric stiff so it would look like it was waving. The whole flagpole was aluminum tubing, weighed under 10 pounds, cost $75 to build. The flag rode to the moon strapped to the ladder of the landing spacecraft, directly in the blast path of engines that hit 2,000°F on the way down. Engineers had to wrap it in a metal sleeve with insulating blankets just to keep it from burning up before anyone could touch it. Then Armstrong and Aldrin tried to actually plant the thing. They could barely get the pole into the ground. Dirt on Earth has smooth, rounded grains because millions of years of wind and water have worn down the edges. The moon has no weather. Never has. So lunar dirt is made of tiny jagged shards that lock together like Velcro. The pole went in a few inches, nowhere near deep enough. Buzz Aldrin later told NASA engineers he spent the whole time terrified the flag would fall over on live television while hundreds of millions of people watched from their living rooms. It stayed up. It stood for 21 hours and 36 minutes. When Armstrong and Aldrin fired the engine to leave the surface, the rocket exhaust hit the flag, planted just 27 feet away, and blew it over. Aldrin watched it go down through the window. Every Apollo crew after that put their flag farther from the spacecraft. Six American flags were planted across six moon landings between 1969 and 1972. The last one, on Apollo 17, had actually ridden to the moon and back on Apollo 11 years earlier, then hung on the wall of Mission Control before going back to the lunar surface for good. In 2012, NASA pointed a spacecraft camera at the old landing sites. The lead scientist on the camera team confirmed that five of the six flags are still standing. Apollo 11’s is the only one down, lying in the dirt right where Aldrin watched it fall. Every one of them has almost certainly been bleached solid white. Fifty-seven years of raw ultraviolet light, with zero atmosphere to filter any of it, strips the color out of nylon. The Stars and Stripes on the moon are now, most likely, just blank white rectangles on sticks.

Porque la superstición disminuye la ansiedad al crear la ilusión de tener control de lo impredecible. Pero la complejidad de la ciencia les hace sentir lo contrario, ansiedad de saber que hay gente más inteligente capaz de lograr cosas que ellos jamás podrán comprender.

Insane footage from NASA Artemis I close flyby of the Moon

A Trip to the Moon (1902)

Dato curioso de la semana: Los astronautas entrenan con realidad virtual y adivinen quién está detrás de eso 🫣 La ingeniera venezolana Evelyn Miralles, considerada la pionera de la realidad virtual en la NASA, quien entrenó a los cuatro astronautas de Artemis II. 🚀🇻🇪

Sin palabras. Disfruten la vista Misión Artemis II sobrevolando la Luna

Soy fan absoluto de Jeremy Hansen #ArtemisII

🇺🇸 — Momento histórico. El presidente Donald Trump establece comunicación con los astronautas de la misión Artemis II.

“Luna” Porque acaba de emitirse el vídeo de mayor calidad de la luna.

Buzz did that on video.

NASA Artemis passing close to the Moon

Hay que recalcar que los ingenieros de la union sovietica debieron ser muy buenos para lograr hacer ingenieria en comunismo. Lo digo por experiencia propia

LA ULTIMA CARTA DE LOS SOVIÉTICOS ANTES DEL APOLO 11, LA HISTORIA QUE POCOS CONOCEN. Hilo🧵: Como todos saben, llegar a la luna solo era una cuestión de orgullo en la guerra fría, ningún país (URSS o EE.UU) tenía un plan a mediano o largo plazo después de dicha conquista. 1/13

🚨: ¡La última foto de la superficie de Venus tiene ya 40 años! El módulo de aterrizaje Venera-14 llegó a la superficie en 1982, permaneciendo 52 minutos a la temperatura de Venus de 450 °C (847 °F

Moon stuns in the latest video released by NASA!

🚨 Live look at Orion, the Moon, and Earth lined up “Everyone is in this picture” 🌕🌏

“Where Is My Mind?” is one of those songs that never quite leaves you.

Captada desde la Tierra: la nave Orion de Artemis II sigue siendo visible incluso a una distancia cercana a la de la Luna, y ya hay telescopios que han logrado fotografiarla desde nuestro planeta
