Stephen Baxter’s 2009 book “Ark” has a starship launched by an Orion booster. As with the “Michael” from Niven & Pournelle’s “Footfall,” is it described with a few snippets of text, here and there, but somewhat confusingly and with incomplete detail. I have attempted to reconstruct it for my Nuclear Pulse Propulsion book (“NPP in popular culture” chapter). In short:

1) Derived from 4,000 ton General Atomic design

2) 40 meter diameter dish-shaped pusher plate

3) Apparently only a single stage shock absorbing system… no gas bags or intermediate platform

4) payload composed largely of two 8 meter diameter, 50-meter long tanks

5) Pyramid-shaped  nosecap

6) Lots of exposed structure, looks like a factory

Not shown here are the four glider-shuttles that the starship carries.

Suggestions and critiques welcomes.

This is what you get when you put video cameras all over the Shuttle solid rocket boosters… and let Skywalker Sound enhance the audio.

I kept telling my bosses – and anyone else I could get hold of – back in my ATK days that some of the costs of a Shuttle or Ares V launch could be offset by mounting capsules on the noses of the boosters. Big lightweight capsules with big windows, with room for a number of paying customers who want the wildest ride out there. The capsules would separate a split second after RSRM sep from the ET, and would splash down separately.

Don’t tell me you wouldn’t want to go…

I’ve been looking into Kickstarter as a way to generate some business. It seems geared quite closely to artist types and people looking to set up businesses that require lots of funds. Sadly, the rules explicitly ban campaigns for things like “help me get a new computer.” And since a new computer is what I need, that’s kind of a shame. Additionally: every idea has to be reviewed and approved by humans, and I’d bet good money that most of the ideas I’d try through Kickstarter would get shot down. Oh well.

But the general concept is interesting. Someone says “I need X number of dollars for Project Y by date Z,” and offers a series of goodies of increasing value for specific levels of buy-in ($10, $25, $50, $1000, whatever). People who are interested pledge whatever amount they want. They sign up with Kickstarter and have to assign a credit card. If by date Z X dollars have not been pledged, then the project has failed, and those who pledged aren’t charged; on the other hand, if the project is successful and at least X dollars have been pledged, those who pledged have their credit cards charged and the artist gets his funds.

Seems like a plan. One I’ll copy for my own “I need a computer” project.

So, here’s the deal.  I have, as I’ve shown before, a pretty good 3D CAD model of the 2001 Space Station V. But I need a new computer to carry it any further. I need $600 for this new computer. So here’s what I’ll produce for various pledge levels:

$10: A hearty “thanks” and a PDF file with a few good illustrations of the Space Station V model

$25: As above, plus a collection of 11X17 prints of the SSV, showing it as a “real” design (akin to the numerous “blueprints” of Star Trek ships that people have done over the years).

$50: Everything above, with a MagCloud printed booklet describing the Space Station V. Not the kit or the CAD model, but a fictional, technical account of how the NCA & contractors would go about using the Orion II cargo shuttle and other much heavier lifters to orbit and build the thing, as well as a general overview of the design.

$100: Everything above, with the addition of large-format prints of the Space Station V CAD diagrams, at least 16X20 (probably 24X36).

$150: Everything above, with high-rez, non-encrypted extractable PDFs of the CAD diagrams

The timelimit: hmmm, let’s call it a week or so.

UPDATE: The project was successful in obtaining a sufficiency of pledges; it is now closed to new pledges.

The time to deliver your goodies: rather longer. Several months, I’d guesstimate.

If you’d like to pledge, send me an email: scottlowther@up-ship.com/blog

Don’t send money (unless you have a driving urge to pay off that $600 Right Now) until I’ve actually succeeded in getting a sufficiency of pledges to make it worthwhile.

If this works – and it’s a big if – another idea I’ve pondered is “photographic expedition.” I need to get down to Albuquerque to the nuclear weapons museum in order to take a few thousand photos, but I can’t financially justify it. However, a similar sort of “kickstart” might make it worthwhile. We’ll see…

The Space Shuttle system was seemingly designed for modularity… the orbiter could be replaced, the boosters could be replaced. Payload shrouds could be placed alongside the tank in place of the orbiter, or on the nose of the external tank either replacing the orbiter or supplementing it.

Martin calculated that the payload for the standard Shuttle using lightweight fiber wound solid rocket boosters and a lightweight ET going to a 215 nautical mile orbit would be 60,800 pounds. Payload to the same orbit would increase to 69,700 pounds if the ET was taken all the way to orbit (the more efficient SSMEs would be used all the way to orbit rather than relying on the OMS engines). By using the ACC and dragging the ET and ACC all the way to orbit, total payload would be 60,100 pounds.

A brochure from Martin Marietta describing the ACC is available HERE.

Well, this could be interesting:

Rocket companies hope to repurpose Saturn 5 engines

Short form: Dynetics and Pratt & Whitney Rocketdyne have announced they intend to update the F-1 for the SLS. It appears that these will be for liquid-fueled strap on boosters to replace the five-segment RSRMs planned for the first two launches.

While a decent enough plan for this sort of thing, the reality is that for a booster rocket the size of the SLS, politics is more important than specific impulse in getting off the ground. A Delta rocket can swap out strap on booster rockets to suit needs, but the Shuttle spent thirty years promising advanced boosters,a nd never got anything fundamentally different than what it started off with. If SLS gets built, it may very well also spend thirty years using essentially the same configuration it stats off with.

Today has been all manner of awesome:

1) A few days ago I traded my 6-yea-old cel phone for a new model. Which was good… the old one was buggy, and the battery was bubbling outwards, I had every expectation of it bursting into flames one me. But this morning I discovered that the alarm on the phone does not go off every day, only Monday through Friday. I of course discovered this an hour after I was supposed to wake up.

2) The effort to install cats into boxes for transport to their boarding location resulted in bloodshed. Fingers knew something was up right off, and put up a valiant struggle.

3) ULTIMATE BETRAYAL: That, I believe, was the look I got from Fingers and Raedthinn as I left them in their temporary steel cage accommodations. Fluffy was just a terrified black dot in the back of the cage; Buttons, as always, was excited for a new grand adventure.

4) Checked in and got through security no problem. My flight was to stop in Houston before transferring to another flight to Reagan Intl near DC. There was only a 35 minute layover between flights; I was assured that this would be time enough. However: the flight to Houston has been delayed by forty minutes. Do the math. So, I had to get another flight. A grand total of *one* seat was available, on a different airline going to a different airport (Dulles). I’ll get to Dulles at 11 PM, then have to take a shuttlebus to the motel. I expect, if *nothing* *else* goes wrong (I’m fully expecting that my checked bag will go to Sydney, Australia), that I won’t actually get to the motel until well into Sunday.

I’m glad I thought ahead far enough to put some buffer here. Losing part of Sunday doesn’t cost the expedition too much, but losing part of Monday would be biting into the point of the exercise.

At least this terminal has free WiFi and numerous power plugs.
