It looks like Dream Chaser will have to be downsized:

Fair treatment at last.

The gov't based approach: First pics of Angara 5 assembled
http://www.russianspaceweb.com/angara5_flight1.html

In the Soviet system--missile men rose much higher in the ranks. Pete Worden for example had less brass than fighter jocks half his age. In the US, Lemay and Rickover were our big Chief Designers, after a fashion.

But in Soviet times, missile men even held office--like Kuchma in Ukraine.

Some talk of delays:

But know this--Rogozin may be primed to take over for Putin, where Medvedev failed.

Imagine if Mike Griffin became President...

There have been a number of challenges to the "Eddington limit"; A theoretical maximum in both the mass and luminosity of a star; but this one is one hundred times more luminous than Eddington would allow. It is time for a new rule book...where is Fred Hoyle when we need him.

each shell is dynamically supported within the gravity of the shells beneath. Supraself has a mass of about 2 x 10e12 solar-masses, as massive as the largest galaxies. The outer shell is about 1.2 light years in radius, and 14 square light years in area, which is quite a lot of land to find in one chunk. And of course that's only the first layer; there's another 30 million shells below that. The total habitat area is thus about 2 x 10e23 Earths.

Opening the hangar doors doesn't mean it's back. Maybe someone will find a use for the Stratogoose, but I don't see it ever launching orbital payloads. Between New Glenn, Starship and a couple of really hungry players like Rocketlab, I don't see many of the commerical options surviving, especially this whale.

At least jet tech is coming along:

This vehicle may have been the closest to von Braun's ferry rocket:

I wonder if we might see Starship with some of Alan Bond's engines one day

SpaceX seems intent to standardize their design. Apart from incremental upgrades as we saw with Merlins, i can't see them changing the basic design for some time. They clearly want Starship this to be their 747, for lack of a better analogy. Stretching that analogy, the Raptor will be their JT9-D, which had a 24 year production life. Raptor is designed for rapid manufacturing. As cool as it would be to see some version of Skylon fly, my feeling is reality has passed it by.

Transparent Aluminum made real

 

[Santaman]

It is a ceramic made with aluminium oxynitride, it isn't a transparent metal, there is also (artificial) Corundum which is another crystaline aluminium oxide, the red version is very well liked and called Ruby.
There are more transparent ceramics.

I have to admit I am extremely sceptical of "wings" in space.

There is a reason capsuls are the go to and have some of the best track records in safety and reliability.

You would NEVER have got me on the space shuttle even if paid a billion dollars. However if you offered me a chance to go up on the Soyuz I would not hesitate to say yes.

I don't much like to see boring twinjets down here.
