I’m Anthony Colangelo.

The one mystery they’re still working to solve: it appears as if Chang’e 4 is 90° out of the expected plane.

I find Jonathan McDowell’s paper convincing, and I’ve always loved the X-15, so in the spirit of consistency, yes, SpaceShipTwo reached space today on its flight to 82.7 kilometers.

Scott Tilley leaves us with a few theories towards the end of the post, but this doesn’t seem like a good sign.

An update on this strange saga: Boeing backed out due to Global IP being behind on their payments. That’s almost certainly a half-truth at best, and it’s not a good look to say something to the effect of “We would have continued to take their money if they had any.”

The 2020/2021 New Launch Vehicle sales cycle continues—New Glenn, Ariane 6, and now H3 all have commercial customers. Still waiting on those first Vulcan and Omega contracts.

They are in need of a good example of their flight safety procedures, and while the event will surely be used by some to criticize SpaceX and their operations, anyone looking to give an honest assessment of the situation will come away impressed with the flight operations yesterday.

Well, that was quick.
