Kim Stanley Robinson says they’re impossible.
I call Clarke’s Law about distinguished scientists, even though he’s just a fiction writer.

ULA’s Shot Across McCain’s Bow
When they said they couldn’t bid GPS without RD-180s, they meant it.
Bill Nye
I’m completely unsurprised that he is clueless about the purpose of NASCAR. Does he really think that people would come to watch Prius’s toottling around the track?
A Rewriting Of Space-Policy History
Over at Space News, from the usual suspect.
And then there’s this: SLS rocket could help scientists answer big questions.
Big questions like "Why is this monstrosity chewing up so much budget we can't afford to do any actual science?" https://t.co/q4VgWDs9lo

#ProTip To space-telescope aficionados. SLS is the most expensive possible way to put up a space telescope. https://t.co/q4VgWDs9lo

The Martian As A Comedy
I didn’t think of the movie as one, but I did almost laugh out loud at parts of the book.
The Learning Period For Regulating Spaceflight Participant Safety
It will be extended until 2023.
If we haven’t started flying by then, we might as well give up.
Tethers Unlimited
Just had an interesting visit there, where they’re working on a lot of tech that will reduce (to the limited degree it exists) the justification for large-fairing launch payloads, with new orbital-assembly techniques, including 3-D printing. They’re working on (among other things) ways of building large lightweight trusses for orbital structure, that could lead ultimately to assembly hangars. They’re also developing ways to recycle a lot of plastic goods (like bubble wrap and zip locks) into cord to feed 3-D printers at the ISS. Very exciting stuff.
In Seattle
I had a long trip to get here, starting at 2:30 AM Central (two-hour bus ride from Columbia MO to St. Louis, two-hour plane ride to Charlotte, five-hour plane ride to Seattle), but I’m at the Museum of Flight, where I’ll be giving a talk and book signing tomorrow, for any Seattlites who want to show up. It’s $20 admission to the Spacefest, but it’s an opportunity for a signed book if you don’t have one.
I’ve never been here this time of year. I was surprised at the fall colors.
“Green” Rocket Propellant
Are we a step closer?
It would sure be nice to get away from hydrazine.
Tesla
Is it doomed?
Frankly, if so, I won’t shed a tear. I’ve never been a fan of companies that require government subsidies (as opposed to government contracts, as is the case with SpaceX) as critical to their business model. My only concern is any effect a Tesla bankruptcy would have on SpaceX, but there’s not reason in theory that it should, unless Elon has been continuing to fund it with his own money, which seems unlikely.
