#GPS - I just heard from my publisher that a paperback edition of my book “GPS Declassified” will be published next spring.

@narottamsahoo Pete Wilhelm worked both on unclassified Navsats and classified ELINT satellites. The connection between these programs is little known. youtu.be/rQpEAUmd4Go?si… Here’s one of my appearances with him. thespaceshow.com/show/06-oct-20…

@narottamsahoo Here are slides from Lee Hammarstrom discussing the steps in the 1960s which led to GPS. I spoke with him today. Lee was the 1st chief scientist for the National Reconnaissance Office.

Wow! I am so happy to read the note. Thank you so much for sharing..

@narottamsahoo @gps @isro @IndiaDST @moesgoi @NFSU_Official @arjunmodhwadia @CMOGuj @PMOIndia @HMOIndia @PIB_India Here’s a note from the man who installed the payload which transmitted the spread spectrum signal on NTS-2.

@narottamsahoo @gps @isro @IndiaDST @moesgoi @NFSU_Official @arjunmodhwadia @CMOGuj @PMOIndia @HMOIndia @PIB_India It was sent from my father’s NTS-2 which put the 1st cesium atomic clocks into orbit.

On this day in 1977, the world's first GPS signal ushered in a new era of navigation, forever changing how humanity travels, explores, and connects with the world. Nearly five decades later, India stands tall with #ISRO's NavIC - our indigenous satellite navigation system that symbolizes scientific excellence, technological self-reliance, and the confidence to create solutions for the future. From the first #GPS signal to the rise of #NavIC, the journey reflects humanity's relentless pursuit of #innovation and #India's determination to contribute to the global frontier of space technology. Every #navigation signal is more than a guide to our destination - it is a symbol of human #ingenuity, proving that when #science leads the way, #nations discover new #horizons and build a #brighter tomorrow.

@vintagegazette Yes

@RDEIL Did you see him live? 😊

Johnny Carson hosts guest Bob Newhart on The Tonight Show.

@ClubDeltic Flat earth is false.

@RDEIL There's a way more interesting story of how this earth turned into a planet than there is in the one you're telling, because that one is almost over. Trust me, I fell here with Enoch and Elisha, and the game is over. Join the winning team because the winning team is no more.

@ClubDeltic Nope

@RDEIL You don't say.

@mtrantalainen @RestoreFinland @Rxi_eq @SarasvuoJari @RitaTainola GPS came from the DoD not NASA.

@RestoreFinland @Rxi_eq @SarasvuoJari @RitaTainola Miten sinä tiedät mikä tutkimus hyödyttää pitkällä aikavälillä? Esimerkiksi NASA poltti aikoinaan hurjasti rahaa, mutta sieltä tuli silti keksintöjä tyyliin digitaalinen kamera (CMOS-kennot) ja GPS. Jos NASAn rahoitus olisi estetty "turhana", niin nämä olisi jäänyt keksimättä.

Miksi vähävaraisen kansan tulisi rahoittaa lobbaavaa toimintaa? Vieläpä velaksi. Kohtaava toiminta erikseen.

@TimGlauert @Th0ughtcrime2 @FTFEofficial Here is one of the plans which led to GPS.

@Th0ughtcrime2 @FTFEofficial Please use GPS measurements to show that the Earth is flat.

Every measurement ever proves the earth is a globe

FYI @KatherineMDunn

Brad Parkinson’s Lonely Halls story is contradicted by his August 1973 status report.

An incredible scene last night as the waxing crescent moon slipped behind the vehicle that will one day help return us to its surface. A vivid reminder of exactly what is at stake. Next Starship flight attempt is as soon as Monday.

@TarkerDahl @JayStrellson @alexboge There was this guy named Aristotle…

@JayStrellson @alexboge The world was flat before it was globular. People have known that all, around the world, since ancient times.

An observation from years of debunking that I can't stop thinking about: the more decisive the argument, the less engagement it gets. My routine debunks, the ones targeting familiar claims like curvature photos, gravity denial, or moon landing objections, reliably pull big traffic. Long comment threads. Days of back and forth. The arguments never change and nothing ever resolves, but the interaction is constant. My two most recent flat earth posts are different. They attack the model at its foundation using arguments the community has never had to answer. To date, no rebuttal has appeared. And they earned a fraction of the engagement. Let me steelman the boring explanation first, because it's partly true. Engagement algorithms reward conflict. Familiar debunks trigger familiar objections, which trigger replies, which feed the machine. A post nobody argues under is algorithmically invisible no matter how sound it is. That's real, and it explains some of the gap. But it doesn't explain the silence itself. Flerfs are not shy. They will argue under anything that gives them an opening. They'll argue under NASA baby photos. The absence of even a bad rebuttal is the data point that matters. My hypothesis: conspiracy engagement runs on scripts. Every standard debunk has a community-approved counter that any member can deploy without thinking. That's what makes the back and forth feel endless. It's not reasoning, it's recitation. A novel argument has no script. Responding would require original thought, alone, in public, against evidence. The belief system offers no support for that situation, so the safest move is not to engage at all. Which produces the paradox: the arguments that generate the most noise are the ones the community has already metabolized. The arguments that generate silence are the ones it can't. If you're measuring debunking success by engagement, you're measuring how comfortable your opponents are. Sometimes the quietest post is the one that landed.

@alexboge That was my reaction. If you don’t argue with them, it’s because you’re afraid that you’ll lose. If you do argue with them, that shows that their assertions might be correct..

When flat earthers run out of physics, they switch to psychiatry. Exhibit A below. The quoted post diagnoses my secret doubt, my pride, and my imminent tearful retraction. What it does not contain is a single measurement. No sun height. No dome altitude. No predicted horizon dip. Five paragraphs about my inner life and zero sentences about the earth. That ratio is not an accident. It's the tell. When a position can survive contact with data, its defenders bring data. When it can't, they bring theories about why their opponents secretly agree with them. And the core argument is precisely backwards. Explaining things publicly isn't doubt. Doubt hides. Confidence publishes falsifiable claims and waits to be proven wrong. Mine are all on this feed: the sun's angular size stays constant from sunrise to sunset, ruling out a small receding local sun. A phone accelerometer reads zero in free fall, exactly as Einstein requires and exactly as density-buoyancy forbids. Chicago's skyline hides precisely the amount of building that 50 km over a curved surface predicts. Any one of those could sink me tomorrow. Meanwhile, in two centuries, flat earth has never produced a working predictive model of a sunset. So the standing challenge stays open: name one observation that would end your position. If the answer is nothing, it isn't a theory. It's a loyalty. I'll sit back and be educated about the firmament the day someone measures its altitude. Until then, posts like the one below aren't arguments. They're confessions.

@wingod It’s the only good thing the California Insurance Department ever did for me. I was supposed to attend a quarterly reserving meeting at Fireman’s Fund in Novato. I had a critical filing due and begged off attending it in those pre laptop days.

Yep, it has been almost a generation since the Loma Prieta Earthquake. LOTS of folks here in Silicon Valley are completely unprepared. msn.com/en-us/science/…

@kevconrad2 @SpearOfIzanagi @jbmillen Global

@SpearOfIzanagi @jbmillen False. Satellites are not balloons. That’s a lie. The global position is a satellite constellation in medium earth orbit. So you lied again. Satellite internet exists like Starlink which doesn’t use cell towers. Also cell and radio towers are tall because of the fucking curve

Unbelievable. We have personal iPhone footage from an astronaut going around the far side of the Moon capturing the Earth setting behind it.
