Lorsqu’on voulait envoyer du courrier par missile, parce que pourquoi pas

Carte postale du lancement de l'USS Barbero

Il y a une soixantaine d'années, l'armée américaine avait imaginé une façon tout à fait particulière de transporter le courrier : avec des missiles. Une méthode originale, créative et rapide, certes… Mais qui n'a pas porté ses fruits malgré de très nombreux essais.

Meteor Rumbles Over Houston, as Six-Pound Fragment Crashes Into a Texas Home

22 mars 2026 à 07:34
"It is the talk of the town today — the loud boom, the flash of light in the sky experienced by a lot of folks across the Houston area this afternoon," says a local Texas newscaster. "And then there was this — a home in northwest Harris county hit by something that crashed through their roof." Travelling at very high speed, the six-pound meteorite crashed through their roof and through their attic, crashing again through the ceiling of the floor below. It then bounced off the floor, hit the ceiling again — and then fell onto the bed. CBS News reports: NASA said in a social media post that the meteor became visible at 49 miles above Stagecoach, northwest of Houston, at 4:40 p.m. local time. The meteor moved southeast at 35,000 miles per hour, breaking apart 29 miles above Bammel, just west of Cypress Station, NASA said. "The fragmentation of the meteor — which weighed about a ton with a diameter of 3 feet — created a pressure wave that caused booms heard by some in the area," NASA said in the post. Across the Houston area, residents described hearing a low, rumbling sound that many compared to thunder, even though the skies were clear, according to CBS affiliate KHOU. Earlier this week, an asteroid weighing about 7 tons and traveling at 45,000 mph traveled over multiple states. And last June, a bright meteor was seen across the southeastern U.S. and exploded over Georgia, creating similar booms heard by residents in the area.
