Envelope expansion isn't just about going higher and faster for an X-plane like NASA's quiet supersonic X-59. It's also about understanding how a one-of-a-kind aircraft operates in flight. With each maneuver, engineers collect data and learn more about the aircraft's performance. Learn more about the X-59's most recent flight test maneuvers here: go.nasa.gov/48D7Ngu

I was looking for possibly interesting things to hack on and found that some crazy person has released an emulator for the D17B/D37C guidance computers used in Minuteman missiles. These predate the AGC and the D37C still works today. github.com/Zaneham/minuteman…

I have only a few memories of Columbia, and both Apollo 1 and Challenger happened well before I was born. But with the Artemis II launch coming soon, I want to convey some thoughts on what the risk of human spaceflight means to me [thread]

🔥Full stage test: complete. Our Orbital Adjustment Module (OAM) is flight qualified! Months of work. One flawless execution. A team that doesn't quit. Proud doesn't cover it. 🚀 Sharing a snippet of the 3D printed Raman-2 engine roaring to life as the Raman-mini’s pulse around. 🔥

Before heading to space, our Raman Mini thrusters revealed their beating heart...pulsing to the rhythm of Saare Jahan Se Acha. A goosebump-inducing moment from the Orbital Adjustment Module (OAM) stage test. How did it go? Check back in 24 hours to find out...

The tally today: ~300 pilots • ~400,000 hours. Against an estimated ~1.5 million total MiG-21 hours, that’s roughly 25% captured—plenty more we could not find. 3

On my birthday today, I resolve to operationalise the awesome Indian attack and jet training aircraft, HJT36 Yashas. I'm sure the pilots would love it. Wishing our Aerospace community more perseverance and more strength to overcome challenges. Success is the only option. Jai Hind

The X-59 is ON THE MOVE!👏 @NASA's X-59 quiet supersonic research aircraft has successfully completed its first low-speed taxi test, moving under its own power for the very first time! This is the last series of ground tests for the X-59 to complete before first flight.✈️ go.nasa.gov/3IPqdAk

Don (@astro_Pettit) and I decided to demo how spaceships could transfer rocket fuel (AKA propellant) in space using water bottles, water, and Alka-Seltzer . . . what could go wrong?

🚨Life update: Launching Industrial 47 — a fund to back the forerunners of India’s Industrial Revolution. Over the last decade of building companies, backing founders, and serving in the military, I’ve sensed something profound shift. Quietly, slowly, almost imperceptibly a new audacious India has come to be. A new generation of scientists & engineers aren't just coding anymore - they're designing satellites, building robots, reinventing agriculture, reimagining defence and rethinking energy. Our deeptech startup ecosystem is growing at a staggering 40% year-on-year. For the first time in decades, we're witnessing a reverse brain drain - our brightest minds are returning home to build industries from India. This isn't a coincidence. This is convergence. And the world is noticing. An Industrial India will build out the next century; 1947 marked our political independence, 2047 will mark our technological sovereignty. When software meets steel, when code meets craft, when bits meet atoms - therein the future is forged. You can be the right person, in the right place, at the right time - and yet have a few key pieces missing. Leonardo da Vinci had Lorenzo de' Medici. Walchand Hirachand had the Kingdom of Mysore. Chandragupta Maurya had Chanakya. The founders building the 21st century have @industrial47 There has never been a better time to reach orbit 🚀🇮🇳

I don't cry when I watch movies. The closest I came was during the ending of Spider-Man: No Way Home. But today, I cried watching Good Night Oppy. Thank you @ryanwhiteIV , @NASAJPL , @PrimeVideo , @NASA and @NASAOpportunity .

Y'all asked for it! SLS LAUNCH EDIT! shoutout @Erdayastronaut for his incredible footage!
