Why the Left won’t win it.
Of course, part of the problem is that, as with climate change, they think there is no room for debate. Neither side does. But one side is right.

EXOS Aerospace
It looks like they had a successful suborbital test of SARGE today at Spaceport America (after the earlier successful launch of Crew Dragon early this morning).
[Tuesday noon update]
Russ Blink just posted an explanation of the wobble at Arocket:
The wind picked up as we approached launch and the torque due to the fins at liftoff was getting pretty high, that caused the initial pitch angle and the control PID is pretty close to critically damped, which of course needs to be addressed, however it settled down nicely until we hit a high wind shear which it damped out slowly again after passing through. Still she was heavily influenced by the wind which we are addressing.
The fins on this flight were actually hurting us because of weather-cocking. We intend to remove or reduce them in the future when we have good aero data or modeling to tune the control part of our gnc for that condition.
For those curious in comments…

Freeman Dyson
“We don’t understand climate.”
He’s not wrong.
[Update late morning]
Is climate change like an asteroid, or diabetes? I’d say neither, but to the limited degree that it’s an understood problem, diabetes is a much better analogy.
The Security-Clearance Process
…is about to get a long-overdue overhaul for the 21st century. It takes too long, and costs too much. I haven’t had a clearance in over a quarter of a century, and lack of one has probably limited my income opportunities.

Flight Of Crew Dragon
The mission seems to have gone flawlessly so far.
But even if it’s a complete success with the recovery on Friday, some will still want to slow walk the first crew flight this year.

Canada Joins The Gateway
Bob Zimmerman isn’t impressed.
This will make if more difficult to cancel the Gateway, but it’s possible to do a much more effective gateway, and one doesn’t need SLS/Orion to do it.
Space Settlement
A bi-partisan bill has been introduced in the Senate to make it a national goal (and to extend ISS to 2030). More thoughts after I read the draft legislation.

When do they become super?
