Is the ISS the last aluminum spacecraft?
Maybe for spacecraft launched from earth, but I think it partly depends on sources of materials. There’s a lot of aluminum on the moon, and not much carbon.

Bridenstine has introduced his bill. It has its own domain. Haven’t read yet, but will have thoughts when I have.
The NASA History Office has issued a new book, that is quite long, but has some interesting-looking essays in it.
First he sells several billion dollars worth of cars, then he lands a rocket on a ship, live on television, while throwing a private expandable hab into orbit.
From SpaceX’s standpoint, they now have another used rocket that they will almost certainly refly, for testing if not another operational mission.

I tweeted prior to flight that they were probably expecting a successful landing, given that (unlike last time) they weren’t downplaying chances of success. Nice to see Elon confirm that.

Hope I’ll see some of you at Space Access.
We’ll see how long they can keep that up.
A nice poster from S&MA at JSC.
We need a lot more of these. https://t.co/eBTcCPSC6a

Heard abut this on the local news this morning. My condolences to the young man’s friends and family, but this seems like a Darwin Award contestant.
An update from Eric Berger in the wake of the successful third flight of New Shepard. The long setback to reusability caused by the Shuttle is finally coming to an end.

I wrote a piece a while ago with this theme, but I may have never published it:
Some people have also questioned whether it’s safe to reuse rockets, but Bezos thinks that perception will flip 180 degrees. “That is an argument that’s been made, but I have a different opinion,” he said. “I would much rather fly in a used 787 than on that 787’s first flight. Let somebody else take that first flight. Look, the fact that you just flew it yesterday means that it’s probably really good to fly right now. And that’s going to be true of rocket vehicles, too. In the future, because of reusability, nobody with a really expensive satellite is going to want to put it on an unused rocket. They’re going to decide that’s too risky. Now that will take a while, but that’s what’s going to happen.”
…”Our first orbital vehicle will not be our last, and it will be the smallest orbital vehicle we will ever build,” Bezos said. And to make it all affordable, says the man who has upended online retailing with Amazon.com, rockets must launch, land, and then fly again. When he’s asked about plans by government agencies and others to build large, expendable rockets, Bezos seems unable to understand that kind of business practice in the 21st century.
“What I know you cannot afford is throwing the hardware away,” he said. “Hardware is so expensive. Look around at the precision you see here. The turbopumps with beautifully machined propellers. It’s just a tragedy to throw all of that away. You can never make a step function change in cost if you’re throwing the hardware away.”
In a couple decades, people will marvel at the stubborn persistence some in throwing expensive hardware away.
I agree with the comments over there. This is ridiculous.
I’m particularly amused by the hand wringing about “space-rated” parts (which is as silly and meaningless these days as “human rating”), and the (completely arbitrary) LOC probability of 1 in 270.
