This recent paper is super interesting... Using ultrasound imaging to generate images of the entire in vivo human cross-section in the abdomen and thighs Basically trying to do CT/MRI-like imaging but using ultrasound! Ultrasound imaging is highly underrated :)



Successful launch!🚀🚀🚀🚀🚀🚀🚀🚀🚀🚀 All satellites were captured within minutes and already orbiting Earth with all systems nominal. Congratulations to the incredible AST SpaceMobile team! 250Y U.S.A. 🌎📶 🤠



The notion that your doctor's training is an indicator of their skill is a fallacy. There is no medical school, residency or fellowship that always produces flawless doctors. Any graduate of any training program is capable of making mistakes. I've seen big saves and huge errors in doctors from Harvard. Also seen big saves and enormous errors in community docs who trained miles from Ivy league hospitals outside the US.

What is $ASTS' price post BB8-10 launch?




Fired up. Ready to go. It’s time to take back Texas.



Starlink doesn’t need to match the performance of Bluebird to compete in the market, they make up for sub-par D2C performance with sheer launch volume, mass-production, and their vertically integrated launch services, which they have the liberty of being able to do because they have gone through the arduous task of ramping up the cadence of Falcon 9 to the highest in history, all while routinely reusing boosters and keeping the vehicle so reliable you can put humans on it. Plus who knows how Bluebird will perform when there’s thousands of customers using the same satellite. It’s not the same thing due to massive differences in orbits, but take Viasat for example, their satellites have a LUDICROUS amount of throughput, covering entire countries with a gargantuan phased-array, but many customers have their data routed through that same satellite, which causes horrible congestion. Starlink’s Internet satellites pale in comparison to the big GEO-based ones in terms of bandwidth, only being able to create around 15 beams per spacecraft, but because the constellation is so large, there’s plenty of bandwidth to go around, especially with laser backhaul. Obviously there are some major differences, phones do not have phased-array transceivers and Bluebird will be placed into LEO alongside Starlink, but I think it’ll work, for one, I’ve tried the service, which was seamless, and there are a few other companies piling on to D2C, including Kuiper, as Amazon spent 10 billion to acquire Globalstar, with another 10+ billion going towards launch purchases, mainly for their Internet service, but who knows if we’ll see D2C on those flights as well, but I am guessing, like Starlink, they’ll simply use modified Kuiper Internet sats.
