Spinning out? We get it. 🌀

Landsat 8 captured these swirling clouds over the Southern Ocean on Feb. 11, 2026. The counterrotating spirals formed as flowing air was deflected by Peter I island and spun into eddies.

@FelixSchlang @Spacepointorg @SpaceX Exit was just as impressive.

Too many people building stuff to get to space and not enough building stuff that needs to get to space.

This motor is putting out just enough torque to offset gravity.

And its doing it by using mass data calculated from gcode.

In robotics, you often want to know the masses, centers of mass, and inertia tensors of links. If you have 3D printed parts, just calculate from gcode

@KyleMorgenstein I'm wearing one right now because I got it for free at a math conference. Comp. Math senior rather than ME freshman though

@endless_sine I love that episode

[Blue Origin @blueorigin]

We’re standing down on today’s launch attempt to troubleshoot a vehicle subsystem issue that will take us beyond our launch window. We’re reviewing opportunities for our next launch attempt.

Had to bail out of seeing New Glenn because of a 9 AM class. Good luck to all still watching!

[Blue Origin @blueorigin]

New Glenn’s new T-0 is 1:31 a.m. EST / 0631 UTC.

Afterburn glow 🤩 ✨

We recently completed the first maximum afterburner engine run test on our X-59 quiet supersonic research aircraft. The ground test, marks a significant milestone as the X-59 team progresses toward flight.

With New Glenn & Starship expected to launch within days of each other I'm seeing a lot of people saying that New Glenn is too late and already redundant.
However, New Glenn's much delayed launch is intended to be a fully operation launch system, Starship is still in development.
Starship 100 ton payload and 9 meter wide cargo are massive compared to other rockets, but New Glenn gets 45 tons and a 7 meter wide fairing, also bigger than anything else out there right now.
And consider that Starship is still working with a Pez dispenser satellite system which limits its use until they figure out how to put a big door on the side. Even then I suspect it'll maybe accommodate payloads of up to 8 meters.
If anyone needs anything bigger, starship would need to be rebuild, while New Glenn could more easily adapt to add a hammerhead style fairing like Falcon 9. Just in case anyone wants to launch a 10 meter telescope mirror 😉
For delivering higher energy payloads on interplanetary trajectories, Starship would need to carry an upper stage into orbit and then deploy that. New Glenn already has a high performance hydrogen upper stage capable of sending spacecraft to GTO or beyond before it needs to think about adding a third stage (which is something that was certainly talked about at BO).
SpaceX of course can continue to expend falcon Heavy cores if it needs to do this, it's just not being revolutionized by Starship any time soon.
On the reusability front we know that the core and fairings are intended to be reusable and while the current second stage is expendable Blue Origin had a team working on 'Project Jarvis' which has laid the groundwork for a fully reusable upper stage, it's within the realm of possibility this capability comes to New Glenn

And then there's already customers, at the very least Amazon has a lot of payloads it wants to fly on NG rather than alternatives.

So while the mass to low earth orbit and 100% reusability capabilities of Starship are going to be game changing in the coming decades, they're not the only metric by which a launch system is judged by potential users.
