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.

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.

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.

Reaction Engines Hype

The UK investment into Reaction Engines is drawing some hilarious stories. First, it should “keep Elon up at night“:

Skylon, thanks to BAE investment and backing, has the chance to become the first true space plane that can take off from an airport, fly into space, and then safely return to the atmosphere and land on the same tarmac where it took off. From there, the path to further space exploration can be achieved. For the time being, SpaceX has not yet been able to produce an effective disposable rocket.

This incident, together with the loss of the Progress rocket last April and Cygnus in 2014, are likely to cause some logistics problems for the ISS. Had SpaceX’s launch been successful, it would have marked a significant milestone for the future of space travel. However, this is not yet the case. Despite SpaceX’s reassurances, there is evidence the company may need to make significant changes or abandon ship.

And yet, interestingly, no such “evidence” is provided. #ProTip: A rocket that has successfully delivered payloads to orbit nineteen consecutive times, and which continues to sign up launch customers, is an “effective” rocket, disposable or otherwise.

This is what happens when airplane designers try to build a launch system (I saw this with North American people during the NASP program as well). They don’t understand how launch systems work, they don’t understand the source of the cost, and they think that the solution is to build an airplane, because everything look like a nail. No one actually familiar with the launch industry would write a silly article like this.

And then there’s this:

The 24-hour slog from Sydney to London might soon(ish) be a thing of the past, thanks to the UK government.

The Brits have just pumped £60 million (USD $92.40 million) into a next-generation engine that — its makers claim — will make low-cost space travel possible for commercial customers.

But you and I might not be stepping abroad this super-plane for a while yet. The new ‘Sabre’ engine — a hybrid rocket and jet propulsion system which theoretically allows travel anywhere on Earth in four hours or less — is still at least a decade away, the Independent reported.

And if and when it happens, tickets will be a million dollars each.

Back In Missouri

We drove back to Columbia today from west of Ann Arbor, after visiting family and friends up there. Initially took back roads, not the freeway, as we were trying to catch the last of the fall colors. I took Route 12 from south of Manchester all the way to Coldwater, through the Irish Hills which, despite having been raised in southeast Michigan, I’d never done, so if I had a bucket list, I’d cross that one off. Lovely (but looking a little depressed in off-season), and Michigan International Speedway was impressive from a distance.

From there we headed south to Fort Wayne, went east on 24 across northern Indiana. The plan was to go to Peoria, then continue down to Hannibal, but we realized that we would run out of light (and butt stamina in the car) long before we ran out of road, so we bailed not long after getting into Illinois, and took 57 south to 72, then 55 south to 270, then 370, then 70 west to Columbia. Got in about 7:30. Always nicer to gain an hour from the time change than losing it (we got into Michigan about 10 PM when we drove up Friday).

Anyway, here until Friday when I fly to Seattle for a book signing at the Museum of Flight on Saturday. Hope locals can make it.
