Plus: LK-99 superconductor sample could be ready in ‘weeks’ The Cold War concept of orbita

Plus: LK-99 superconductor sample could be ready in ‘weeks’ [Blueprint]( The Cold War concept of orbital “Rods from God” — telephone pole-sized tungsten rods that would strike like meteors — has taken on a near-mythical status as the ultimate bunker buster. But surprising new Chinese research reveals raining down rods from space may not penetrate bunkers as deeply as believed. Find out why in today’s [Must Read](.

[SUBSCRIBE]( Must Read [‘Rods from God’ not that destructive after all, Chinese study finds]( 💥 “Rods from God” - orbital tungsten rods deployed to strike like meteors - have long seemed the ultimate bunker buster. But Chinese research now reveals hypersonic impacts may not penetrate as deep into concrete as expected. At 9 times the speed of sound, an entire rod arm-length vaporized on impact in experiments. The resulting plasma eroded the rod away instead of deepening the crater. Beyond Mach 5, ultra-high speeds did not improve penetration any further. While they are still likely to be devastating at the point of impact, this finding challenges the bunker-busting abilities of orbital “Rods from God.” [Read More]( HOT TOPICS - 🌄 [Solar power generation averted Europe's heat crisis]( Solar panels played a leading role in addressing the increased electricity and cooling demand during heatwaves. - ❎ [SpaceX tests Super Heavy prototype ahead of Starship launch]( Elon Musk says Starship has a "~50 percent probability of reaching orbital velocity" during its upcoming second test flight. - 😵‍💫 [NASA finds Mars days shrinking, cites increase in spin speed]( The data indicates Mars is spinning faster each year, leadi ng to a slight annual decrease in the length of a Martian day. - 🌡 [Ancient lake microbes triggered 304-million-year-old warming]( A recent study uncovers ancient warming secrets of a Paleozoic ice age. - 👁 [Lab-grown cells promise to cure age-related blindness]( Retinal pigment epithelial (RPE) cells grown on 3D nano scaffolds could treat age-related macular degeneration, a disease that blinds millions.

Flesch reading score

Flesch reading score measures how complex a text is. The lower the score, the more difficult the text is to read. The Flesch readability score uses the average length of your sentences (measured by the number of words) and the average number of syllables per word in an equation to calculate the reading ease. Text with a very high Flesch reading ease score (about 100) is straightforward and easy to read, with short sentences and no words of more than two syllables. Usually, a reading ease score of 60-70 is considered acceptable/normal for web copy.
