Prepare for takeoff. ✈️ Flight simulator is now available globally on web to all users. goo.gle/4fBYnWO We've recently added many our most powerful professional desktop features to web. Elevation profiles, new import types, but there's always been one other feature you've been asking us to add to the web version of Google Earth, just for fun... Where will you fly? Share your best maneuvers, views, and flyovers with us!

The first low Earth orbit (LEO)-optimized Centaur upper stage is now integrated atop the Vulcan rocket at ULA's @AmazonLeo Integration Facility! Integrating the vehicle with the new LEO 85K Centaur upper stage allows the team to perform first time procedures, validate stage and ground support equipment interfaces with a planned Wet Dress Rehearsal to validate new technologies in advance of the first Vulcan Leo mission.

We go where we need to be, and today that was @NASAKennedy. Some of my senior engineers and I spent time at @blueorigin with @JeffBezos and @davill, speaking with the workforce and seeing the damage at LC-36 firsthand. I appreciated the opportunity to hear directly from those working through the aftermath and better understand the challenges ahead. There is a lot of work to do, but this is exactly why people choose careers in aerospace, whether at NASA, Blue Origin, or across the industry. The talent in this field thrives under pressure and performs at its best when solving the toughest problems. We have been saying for months at NASA that we are not going to sit on our hands and wait for the capabilities necessary to achieve the nation’s most pressing objectives. We are going to take an active role alongside our partners, just as we did in the 1960s, to overcome setbacks, remove obstacles, and deliver the intended outcomes. @NASA is committed to helping the Blue team recover, continue to advance their lunar lander and get New Glenn back to launching as soon as safely possible. America’s greatest achievements in space were never the result of avoiding setbacks. They came from overcoming them. We have done it before, and we will do it again🇺🇸

All personnel are accounted for and safe. It’s too early to know the root cause but we’re already working to find it. Very rough day, but we’ll rebuild whatever needs rebuilding and get back to flying. It’s worth it.

SpaceX drops the hypiest IPO filing and says "we believe we have identified the largest TAM in human history", and you're like, my interplanetary east India company, what delectable spice have you decided to ship across the stars, and it's like... 22 trillion dollars of b2b saas

Polish Cadet Bartosz Szumowski, a second-year cryptology and cybersecurity student at the Faculty of Cybernetics at the Military University of Technology in Warsaw (Poland), has been accepted into the elite U.S. Military Academy at West Point, the oldest military academy in the United States. This is an extraordinary achievement as West Point limits its international intake to only about 15 foreign candidates per class. It is also symbolic, because Polish General Tadeusz Kościuszko was appointed by the Continental Congress to oversee the fortifications of West Point from 1777-1780 during the height of the Revolutionary War, when George Washington considered West Point to be the most important military post in America.

Insane that we'll end up producing 99% of our energy from space, and send it down as intelligence. Literally no other way to send this much energy back — intelligence ended up being the densest form of energy we discovered.

Just how much are we spending on AI? Compared to other massive infrastructure projects, AI is the sixth largest in US history, so far. World War II dwarfs everything else at 37.8% of GDP. World War I consumed 12.3%. The New Deal peaked at 7.7%. Railroads during the Gilded Age

During the peak years of the railroad industry in the United States — roughly from the 1870s through the early 1900s — railroad stocks dominated the U.S. stock market, comprising about 60% to 70% of total market capitalization.

In the 1940s, my grandfather would ride the International Railway Company (IRC) street cars from the edge of the Village of Lancaster over to South Buffalo where his mom worked. By then the IRC rolling stock was end of life and hadn’t been replaced with newer units.🧵

I’m a bit nostalgic about how far you could take street cars for rail travel around WNY before automobiles became widespread. From Olcott Beach on Lake Ontario to the Port of Buffalo to Niagara Falls, Ontario. Gilded Age mobility. 🧵

This freshly painted brick barn on Forest Avenue across from the @RichardsonCtr near @buffalostate dates back to when it served International Railway Company (IRC) electric street cars that operated in Buffalo from the 1880s to the 1940s. 🧵

Pleased to share my favorite high-resolution capture of the Artemis II launch- the moment the SLS is clearing the tower, captured by a sound-triggered camera placed near the pad. I'll have prints linked in my bio for this one, and here's a short thread about how it was captured

The crew have successfully flown and controlled the Orion spacecraft, demonstrating the capabilities needed for docking with human landing systems.
