The Case of the Missing Vega AVUM Propellant Tanks

Turns out two of the propellant tanks for the fourth stage of the final Vega launch vehicle – a European launcher that first flew in 2012, designed for small payloads – went missing. That’s kinda inexcusable and inexplicable. But at least they found them. That’s good, right? Well…

 

They had been crushed and were found alongside metal scraps in a landfill.

Whoopsie.

Even better: as this is the *last* flight of a Vega, the production lines are long since shut down. So in order to pull off the planned 2024 launch, either tanks from pre-2012 ground tests will be scrounged – assuming they’re still in good enough shape – or a whole different unqualified-for-Vega upper stage will be used.

 

Maybe just fly on a Falcon.

Starship: Take 2

The second Starship/Superheavy launched today. Vastly more successful than the first flight, but both stages were still destroyed.

This sort of thing would be unacceptable for a modern NASA launch system… but it was common in early launch vehicle development. Atlas and Titan kerploded with regularity. This sort of thing is not desirable, but it is a natural part of the learning process.

Scott Manley has done an analysis of the video and has some good suggestions about what happened with the booster. There would seem likely to be some serious issues with slosh and propellant hammer effects, caused by the sudden deceleration and flip maneuver. These are resolvable.

But beyond the technical issues and successes… this flight was simply *gorgeous.*

Enterprise found

Several models of the Starship Enterprise were built for the original “Star Trek” series. The most famous is the 11-foot model which was used for most of the effects shots, and *amazingly* managed to survive long enough to end up in the hands of the National Air and Space Museum. But before the 11-footer was a 3-footer. This was made early on, and was solid wood with no lighting; still, it was used in a number of shots. This model stayed in the hands of Gene Roddenberry, modified to rest on a mike stand bolted to a wooden base. This model was lent to the first special effects house during the production of the aborted “Star Trek Phase II” series in the mid-70’s… and then it vanished. Whether it was stolen, misplaced or lost has not been clear, but Roddenberry considered it to be stolen. Stuff like this that disappears stands a good chance of never being seen again. Witness many of the models made for “2001: A Space Odyssey.”

But then, the “Aries Ib” model for “2001” was found a few years ago. And as it turns out, that 3-foot Enterprise was recently found. It was in a storage unit, purchased by someone who buys such things at auction. The new owner then put it on ebay with a starting price of a mere $1000. And then Star Trek fandom found out about it and has been going nuts. The Roddenberry estate contacted the seller and the auction has been pulled.

News was revealed here:

https://www.therpf.com/forums/threads/red-alert-lost-3-ft-tos-enterprise-found.354596/

The current seller has broken no laws… it seems he just bought an abandoned storage unit. But the Enterprise remains stolen property and should be returned to the Roddenberry estate. Still… it sure seems like the seller aught to be compensated for finding this thing, even if he didn’t really know quite what he had. It’s in pretty rough shape, as can be expected. With luck it’ll receive some sort of restoration, though arguments can be made for exactly how far that should go. It should definitely be cleaned up. It’s drooping and cracked; that should be fixed. But fixing the paint and decals? I don’t know about that. Perhaps it, unlike the NASM Enterprise, should retain the appearance of years. There are some “errors” that were there from the beginning, those should stay.

It is very unlikely that this will ever see an auction. But if it does, it’ll doubtless go for Lotto-levels  of cash.

US Justice Dept sues SpaceX over hiring practices

 

“Our investigation found that SpaceX failed to fairly consider or hire asylees and refugees because of their citizenship status and imposed what amounted to a ban on their hire regardless of their qualification, in violation of federal law,” Assistant Attorney General Kristen Clarke said.

 

How about No. SpaceX is building the future of national security. I say let them be as got-dayum picky as they want to be *especially* when it comes to hiring people of dubious loyalty.

The next time we get a President who is non-insane, non-senile and pro-America, they need to go through the halls of the Federal Government with  leafblower hooked up to a backpack full of pink slips.

Aug 182023
 

Thanks to ebay and my fabulously lean bank account, I have recently procured a number of items of potential interest:

“NASA Earth Orbital Space Station,” a poster-sized lithograph from McDonnell Douglas depicting a space station that tumbles for artificial-G.

“Re-Entry Payload Launch Vehicle,”  A *brief* General Dynamics presentation on a vehicle to launch re-entry vehicles such as MIRV warhead shapes

 

“Proposed Development Program on Rocket-Type Missiles,” a 1948 Convair report on early ballistic/boost glide missile concepts, that would lead to Atlas. Includes some fantastic large format layout diagrams.

 

“Detail Specification for Consolidated Vultee Model 117 Airplane Class VR Transport Flying Boat,” August 1950, all the details on the then-brand new Tradewind.

 

 

“Detail Specification for Class VP Long Range Patrol Seaplane,” Consolidated Vultee 1946, all the details on a proposed flying boat patrol/bomber

32 issues of “Astronautics” magazine from 1957 to 1969, mostly 57-59 and 63 or so.

The lithograph and the reports will be scanned and put forward for consideration for monthly rewards; the magazines will have the interesting bits scanned and made available to the subscribers/patrons.

$200 a round rocketgun

Here’s something you don’t see too often… someone firing *numerous* rounds from a Gyrojet. Each of these .45 caliber rounds are solid propellant rocket units, last manufactured in the 70’s or so. They apparently run about $200 *each,* which makes me wonder if there might be a market for newly manufactured ammo. As a practical  home defense, police or military weapon… the Gyrojet basically wasn’t. It took something like 50 feet for the round to reach maximum velocity, which means at close range it might just bounce off an opponent. But as a range toy they might be fun, especially if the cost per round could be dropped substantially. And there’s no reason why it can’t… sure, each round is more complex than an equivalent conventional bullet, but they are just some basic parts with 1960’s rocket propellant. And that last could doubtless be improved; better propellant, better grain design and better manufacturing of the nozzle plate could *really* boost performance.

The claim is made here that the Gyrojet was designed to be used in space because they were uncertain if conventional gunpowder firearms would work in a vacuum. This is untrue; nobody with the least bit of understanding of the chemistry of gunpowder and how guns work thinks that guns *won’t* work in space. However, conventional firearms do have three major issues for space applications:

  1. Recoil.
  2. Thermal issues: exposure to sunlight and vacuum means that small metal devices like guns heat up *fast.*
  3. Vacuum issues: grease, gun oil and the like boil off quick, meaning they can’t be used in space.

 

The Gyrojet has far lower recoil than conventional firearms. And the Gyrojet is a far simpler mechanism, made largely from stamped metal sheet to far lower specifications. This means it can heat up without jamming, with virtually no need for lubricants. So the Gyrojet seems like it’d make a dandy sidearm for the USSF. Bump it up to .75 caliber and you have yourself a light bolter. And perhaps best: home manufacture of Gyrojets would be *easy.* A 3D printed Gyrojet, with some *basic* metal parts, would not only be easy to make, but with vastly lower forces imparted on it than a conventional firearm, it’d be far less likely to explode.

 

So… where are the new-manufacture Gyrojet rounds? At $200 a round for the vintage stuff, you can start off *real* expensive and still undercut the current market.

KSC Master Plan

Recently acquired at some cost, and finally fully scanned at some effort, is this 1965 “Master Plan” for Kennedy Space Center. It’s basically a book of maps of the region showing all aspect of the infrastructure. It’s in good shape and was scanned at 600 DPI rather than the usual 300, due to the fine quality of the maps. It will be in the next catalog for Patrons and Subscribers to vote on. It’s a little out of the usual for APR… it’s not about unbuilt aircraft or spacecraft; in fact, no aircraft or spacecraft designs are included. But it’s still an interesting historical artifact.

I also have a KSC Master Plan from the Shuttle era. Substantially larger format, with more conventional full-color maps. I haven’t scanned that due to the chore it would be to get done, but if this proves popular, I’ll get on it. I *also* have a large-format Master Plan for Ames Research Center.

 

If you are interested, check out the Historical Documents Program.
