Here’s a presentation describing a number of European space transport concepts, including the HOTOL, Sanger II and Hermes spaceplanes, Automatic Transfer System and a few others. As a presentation, it is loaded with illustration. I have clipped out some of the better Hermes illustrations and included them below.

Checking out tonights TV listings, at 8 PM and 11PM (Mountain Time… go ahead and convert it yerself, ya coastie buggers) on the “American Heroes” channel (287 on DirecTV) is:

Hitler’s Death Ray: Nazi scientists work on  developing a solar mirror that could destroy any city on Earth while situated 5,100 miles in space.

I have the feeling that I’ll wish that I had the capability to record this. VHS doesn’t work anymore, don’t have DVR, so there ya go. I’ve got the urge to yell at something monumentally stupid, and this would seem to have a full hours potential for “Ancient Aliens”-level dumbth coupled with either lazy CGI or potentially surprisingly spiffy CGI.

UPDATE: Well, unshockingly, that was crap. Spent a total of maybe two minutes on the Nazi Space Mirror, providing exactly zero new information. *Claimed* that there were detailed plans, showed zero evidence of it. The rest of the “documentary” was a generic “Nazis had advanced technology and built rockets, blah, blah” schtick. Even threw in Die Glocke to round out the quota of requisite bullshit.

Cripes, the narrator couldn’t even get Eugen Sanger’s name right: repeatedly called him “Sanager.” Bah.

The next US Spacecraft Projects was supposed to have one set of diagrams created via 3D modelling, but it’s looking like that’s not going to be the case. This one was going to be done via old-school 2D CAD, but the complexity demanded 3D. By doing so it opens up a few opportunities for other things…

I have added the full-rez version of this to the 2015-07 sub-folder of the APR Patreon “Extras” folder on Dropbox. What is depicted is a 1985 Martin Marietta design for an Unmanned Launch Vehicle, a Shuttle derived vehicle that replaced the Orbiter hanging off the side with an inline payload shroud up top and a small propulsion/avionics module that would have three SSME and two OMS engines, in much the same positions as the Orbiter engines. This would allow the booster to lift off from existing Shuttle facilities with minimal modifications. The P/A module would be a biconic lifting body allowing recovery and re-use. Not only would the P/A module go into orbit, but so would the external tank. Each flight of this vehicle would have the potential to orbit the shell of a fantastic space station. This vehicle was described in greater detail in US Launch Vehicle Projects #2. MM Inline Shuttle Derived Vehicle 1985 If you are interested in the high-rez version of this, it and many more are available to all $4 and up patrons at the APR Patreon.

Putting together the 3D CAD model of a General Electric has been complex but straightforward… but hammering the 2D diagrams made from it into shape has proven a bit challenging. Most of the 2D work is done in an ancient version of AutoCAD, but there was something about the diagram (created in Rhino 3D) that caused ACAD to either lock up or crash. So finalizing the diagram has been done in Rhino, which means the diagrams will look a little different.

A follow-up to the earlier photo set of Burans at Baikonur left to rot: a full -scale mockup of the Energia-M launcher. The Energia-M was a planned smaller two-booster version of the four-booster Energia used to launch the Buran orbiter… and, like the Buran orbiters, it has been left in place and is slowly rusting away.

I have added three hi-rez scans to the APR Patreon “Extras” Dropbox folder for the month of 2015-07. If you are interested in these, they are available to all $4 and up patrons at the APR Patreon.

Avast amount of work was put into space-based weaponry during the SDI days, but the bulk of that work has remained tucked behind security classification. Artwork was released publicly from time to time, but with rare exceptions that artwork was pretty clearly either not based on actual engineering design work, or was stripped of important features.

In all my digging I’ve found a grand total of *one* illustration of a space based railgun that I’m fairly confident represents a serious design effort. Sadly dimensions were lacking… but the design included a nuclear reactor and radiator system was was very likely an SP-100. While the SP-100 system itself appears to have been in constant flux,  scaling the whole assembly from the size of the radiators leads to something I’d estimate accurate in scale within +/- 15%.

For a future USSP release, I decided to include this railgun as I included the Zenith Star laser in issue #1. The easiest way to make good 2D diagrams for something this complex is to make a 3D CAD model based on the sketch, including the SP-100. I didn’t know how big the railgun was supposed to be; I didn’t try to scale it until I had it largely put together with the SP-100 in place. And boy, is it *not* small:

shuttle+railgun

The shuttle is of course to scale.

Several details lead me to think that this General Electric concept is on the up-and-up:

1) It includes the SP-100. This was often (not always) left off of images for public consumption.

2) It includes *very* large planar array radar for targeting warheads thousands of kilometers away, something I’ve *never* seen elsewhere, but which is pretty obviously important.

3) It has a fairly substantial, though unclear, storage for LOX and LH2 hidden behind a thermal shield/radiator. Note: the nuclear reactor was to keep the system running for years while awaiting The Day, and for running systems like computers and radar and such. But the power needed for the railgun was vastly more than the SP-100 could provide; the LOX/LH2 would run a turbogenerator to crank out the megawatts needed to make the gun go bang.

4) It doesn’t look “sci-fi cool” so much as it looks like a “great big thing built in space.”

Launching this monster would have been a hell of a chore. Presumably it would go up in pieces atop  an ALS booster, and there assembled by a human crew launched via shuttle.

Rockwell art of an early Shuttle configuration. The full-rez version has been made available for $10-level patrons at the APR Patreon.

While this is broadly much like the STS as actually built, there are a lot of important differences. The spine down the top of the cargo bay… that was to give room for the cargo manipulator arm without putting it actually in the cylindrical bay, taking up valuable cargo space. The booster rockets have teardrop ports on the cylindrical sections just aft of the nosecones… these are the thrust termination ports that, in the event of an abort, would blow out through the forward dome of the rocket motors. This would not only slash the chamber pressure in the motors, it would provide an escape route for the hot gas to go forward, cancelling the thrust from the aft nozzle. The ET is of a slightly simpler geometry; the small cylinder on the nosecone contained the de-orbit solid rocket motor (because the ET would either go into orbit with the Shuttle, or so close to orbit that the splashdown location would be somewhat randomized).
