OK Boomers In this iPhone video by John Cyrier from our vantage point to the south, you can see the sonic boom in the air at 20 seconds and hear it BOOM at 47 seconds. Incredible body feel. “A sky scraper went into space, returned to earth, and parallel parked” - Sylvia Smith

Photon Fun This FOT is made from 90 million optical fibers fused and stretched. It magnifies whatever it is on top of by 3x without lenses. Each fiber is like an independent pixel, stretched 3x. This is the same multi-channel approach Mojo uses for optical links in data centers.

How Russian air bases fell to a novel multimodal drone attack ✈💥✈✈💥✈💥 Video includes Tu-95 strategic bombers and 41 planes near Northern Finland and deep in Russia, North of Mongolia. Operation Spiderweb: four Russian airbases attacked a few hours ago in a new transport method with large trucks delivering drone swarms from their rooftops to target specific target locations on each plane to maximize damage. While operating autonomously, remote tele-operators in Ukraine used Russian telecom networks to connect to the trucks, which received video feeds from each drone over unspooling fiber optic lines (immune to jamming). The trucks self-destruct after the attack. It was a swarm of small quadcopters in broad daylight, easily evading Russia’s layered air defenses. No Ukrainian losses in this special military operation. Billions lost for Russia, some of the nuclear bombers are irreplicable. Video clips from Special Kherson Cat 🐈🇺🇦

Dean Kamen demonstrates his low-cost self-administered vaccine delivery invention. No skills needed. No scary needle. Localized delivery to dendritic cells in the skin (to better promote an immune response). Universal vaccines (a single lifetime shot for all flu, HIV, malaria, or coronaviruses) from Centivax, Baker Lab at UW, and others will want better delivery methods for billions of people. At SynBioBeta today.

☄️ Of all of my space rocks, this Bjurböle is quite special, as it was recovered from the seabed, with great effort, in 1899. It is the only complete recovery of a meteorite at sea. Meteorites hit the Earth randomly, and thus ~70% of them hit the oceans and disappear forever. This claim was a reasonable assumption, since 71% of the Earth is covered by ocean, and it was recently verified by analysis of the world’s infrasound sensors used to monitor the nuclear Comprehensive Test Ban Treaty. The sensors recorded meteorite impacts by land and by sea, as seen in the B612 video here. Here’s is how this unique space rock recovery happened: on March 12, 1899, at 9:30pm, a bright fireball screamed over my homeland of Estonia on final approach, making a thunderous noise like artillery fire for what seemed like minutes and smashed into the Baltic Sea. Helsinki’s major newspaper Päiväleht asked for witness details and drawings to help locate the fall. As a result of Finnish citizenry’s efforts, the trajectory of the fireball was triangulated, and its impact point was determined to be in the Baltic Sea about 50 kilometers from Helsinki. Because the Baltic Sea was still frozen over in March, there was evidence of the point of impact — a three-meter hole in the surface ice. Then the recovery effort: they tried to find it by poking around with sticks, but the meteorite was 25’ down on the bedrock. So, they built a waterproof well out of wooden beams and dropped it through the hole in the ice. The well was pumped to empty out the water and mud. This did not succeed completely, but in the end a diver was able to find the fractured meteorite and pull it out. It was then displayed the following year at the World’s Fair in Paris in the Finnish pavilion. Bjurböle is a distinctive LL4 meteorite. It is unusually friable and its fine-grained creamy matrix is packed with chondrules — spherical silicate-rich droplets of fiery rain that aggregated from the dust and ice of our early solar system, before the planets formed. It also sports the catalog stamp of the Finnish Museum of Natural History (and was obtained by a meteorite trade).

Close encounters of the fourth kind 👽💞 Out of box first encounter with Grimes' voice in Baby Grok. It's a beta version, and latency will obviously improve... but it sure engages our 4-year old. The Grem version is "an alien that can talk." Thx 𝖦𝗋𝗂𝗆𝖾𝗌 ⏳ and Curio 🤖

Neil Armstrong’s Apollo 11 Hand Controllers 55 years ago today, the mighty Saturn V roared to life and launched Apollo 11 skyward. Neil Armstrong sat in the left seat with this translational controller T-handle in his left hand and this rotational controller at his right — the control joysticks for the spacecraft. But the left handle has a special function at launch: if catastrophe struck on the pad or during ascent, a counterclockwise crank of the handle would initiate the solid rocket engines in the red escape tower, pulling the Command Module away from the rest of the rocket, to return separately by parachute. For the entirely of the Apollo program, that handle was never twisted, even on Apollo 12 when lighting strikes disabled the entire control deck of the Command Module and lit up almost all of the alarms. The user interface continues to the present day, with a similar T-handle at the center of the SpaceX Dragon display deck. The handle felt the same to me, with a similar twist to the left. In the final photos, you see the translational and rotational controllers that flanked Neil Armstrong on Apollo 11. They were removed from the Command Module post flight as with each of the Apollo missions, and after decades in storage, discarded as waste in 1985. They have had several owners since then, and if I can obtain the third controller, I intend to reunite the lot with their spacecraft by donating them to the Smithsonian.
