Whoosh! Straight into the static fire. No messing around here.

[Maritime Launch @maritimelaunch]

With domestic launch, Canada will be able to dictate the schedules and the expansion of Canadian space networks for the benefit of Canada specifically. From new satellites — built in Canada — to an increased space presence, Canadian sovereign launch will facilitate the growth of the Canadian space ecosystem for the expansion of space capabilities.

This new Critical Path video is just mind-blowing. Loved the deluge part of the story.

Starship's launch clamps might be the most satisfying machine in the entire space industry. They are just so perfectly synchronised and so smooth. It's just beautiful.

Traditional CAD handles detailed design well but struggles with the exploration modern programs demand. At CDFAM, Jan Vandenbrande, Former DARPA advisor, makes the case for implicit modeling as the fix. July 16, 10 AM, Washington DC.

nTop joins Istari Digital, @arenaphysica, Luminary, C-Infinity, and SysGit for a live demo updating a UAS design end-to-end and re-certifying it for manufacturability and safety.

This is how SpaceX builds the Starship🚀

@FoodProfessor You are right on that, it was foolish to use alcohol for that, the right retaliation would have been matching the % tarif as an export one on potash and electricity to the US...

[Amazing Physics @amazing_physics]

It is absolutely incredible to see a NASA-built robotic claw effortlessly grasp a rock—a feat previously thought impossible in zero gravity...

🇺🇸 America’s First On-Site Air Separation Plant at Starbase Powers Rapidly Reusable Rockets 🇺🇸

SpaceX is building America’s first large-scale air separation plant across from Starbase launch pads.

Last night I attended Starbase’s Fourth of July America 250 celebration, I could not help but notice this extraordinary facility right by the beach.

The facility produces liquid oxygen and liquid nitrogen on site for Starship propellant and operations.

Starship is the first fully reusable super heavy-lift rocket designed to carry people and cargo to the Moon, Mars, and beyond.

A rapidly reusable vehicle of this size and flight rate cannot rely on hundreds of tanker trucks hauling propellant down a single two-lane highway for every launch.

On-site production removes that bottleneck.

The plant uses cryogenic air separation. Air is compressed, purified, and cooled to extremely low temperatures near minus 300 degrees Fahrenheit. It then flows into distillation columns inside a tall cold box structure. Oxygen and nitrogen separate based on their different boiling points and are liquefied. The liquids are piped a short distance to the launch site tank farm.

This approach cuts long-distance truck deliveries that currently supply liquid oxygen.

Fewer trucks reduce congestion and wear on the only road to Starbase. It also improves supply reliability and supports faster launch turnarounds.

SpaceX designed the plant to help achieve the high launch cadence Starship requires. The project demonstrates American innovation in building the ground infrastructure needed for routine, rapidly reusable orbital spaceflight at scale. Construction is more than halfway complete as of June 2026.
(Photos I took recently show the tall cold box structure, compressors, at the site right across from the pads.)

This is the kind of American engineering that turns ambitious goals into operational reality.

Automated Fiber Placement (AFP) uses robots to lay carbon fiber and manufacture large composite parts for the aerospace industry. It's a highly precise process used to build modern aircraft structures.

@mutanttoad My neighbor lack basic knowledge about the GHIB... We definitely should have known that Trump would want to help his political donors and use this as a lever to cash in... He's the greediest human to ever have lived, we should have known...

[Jean-François Pauzé @jfpauze]

@FoodProfessor When you stick to your lane you do make sense, but here you're far from it! We understand the words coming out of his mouth, doesn't make them true... Stick to talking about things you know, it'll make you look less like a tool. Yeah, it's food prof, not foreign policy prof!

[Westinghouse Nuclear @WECNuclear]

We are one step closer to turning heat into reliable electricity! We are excited to further demonstrate our eVinci™ microreactor heat pipe technology in action with our latest Closed Brayton Cycle (CBC) test bed that will generate real operating data.

A closed Brayton cycle works like a jet engine in a sealed loop: a working gas is compressed, heated in a heat exchanger, expanded through a turbine to produce shaft power, then cooled and recirculated. In this heat-pipe-coupled system, 30 passive heat pipes transfer thermal energy from the heat source to the Brayton-cycle heat exchanger without pumps or other moving parts.

With fabrication of this system complete, testing is underway – marking an important step forward for eVinci microcreactor heat pipe technology.

@GovNuclear @INL The capacity to eventually put this on a crewed spaceship! 🚀

Twelve’s AirPlant One, which it bills as the first commercial-scale facility in the U.S. to produce sustainable aviation fuel (SAF), has begun operations in Moses Lake, WA, the company said June 10. Referred to by Twelve as E-Jet fuel, it is an alternative to traditional jet fuel made from carbon dioxide (CO2), renewable electricity and water.
