Entirely correct, JR. But, tough to set up in the classroom. Had a local teacher do a "full size" ISS layout on the football field a few years ago - not something they can do regularly.
The original thought when I did the first of these a few years ago was to include a similar table - but based on a roughly 3.5" Earth model (can scale the inner planets that way). The Sun would be a 30' sphere about 3000 ft away; the Moon out 8' away from the Earth. Jupiter makes a 30" sphere over 3 miles from the Sun/center, etc. on out. Problem was just how useful it would be in the classroom (have the kids run all over town ...?). My thought here was to have the inner planets sized correctly to each other; separate outer planets sized relative to Jupiter with a little blue bead for Earth on the outer planet display to make a transition. The relative orbital distances for the outer planets would show all the inner worlds clustered/overlapping on top of the Sun/center with the outer planet orbits spaced widely. P-K's suggestions is looking like the most practical solution right now. Yogi |

I used to goof with scaling stuff back then... came up with a way to measure the dimensions of rockets from photographs-- ideally the larger the photograph and the more "straight on" the picture was taken to minimize perspective effects, the better-- so long as I had ONE dimension, I could calculate the others to a varying degree of certainty... (sorta like running my own mini- NPIC... course in the late 80's, there was no internet to get the data from-- bout wore out the Bill Gunston books in the library measuring stuff to build model rockets). I once built a flying SS-17 (as it was then shown in the magazines and books, which turned out to be wrong) and a model Minuteman III... around 1/135 scale for one and about 1/145 scale for the other, IIRC... (been 25 years ago). Even dug a silo to launch the SS-17 in the back yard with a post hole digger and put a paver stone over it for a "silo door"... LOL Worked pretty well actually... At any rate, I got the performance figures and throw weights from one of Bill Gunston's books (Rockets and Missiles of WWIII IIRC) and "scaled" the performance of my models, to the real thing... turns out my Minuteman III model, if it performed like the real thing, would have flown about 180 miles from here (from Needville to about New Braufels, Texas, just this side of San Antonio) and detonated with a force equal to a little less than the Hiroshima bomb. My SS-17 should have flown to basically just the other side of San Antonio and detonated there with the force just a bit more than the Nagasaki bomb... Of course Estes propelled model rockets don't perform anything close to "scale"... LOL Hard to imagine getting that much explosive power in something the size of those little incense spikes either (which were about scale size of actual ICBM RV's...) Later! OL JR

Hey Yogi,
Changing topic just slightly.... Have you built a paper model of Orbital Science Corp.'s Antares rocket? On Monday there is a supposed to be a 29 second hot fire of its engines for the first time this coming Monday on Wallops Island, VA. More here. Antares Pics: |

Antares should be available at ECardemodels. There's also a simpler one at Lower Hudson Valley (jleslie48.com) in the earlier Taurus II livery.
Yogi BTW - the belated creation mentioned earlier (Holmdel radio telescope) is posted in the architecture downloads. After all, it does keep the rain off your head if you're in the instrument shack ... Last edited by Retired_for_now; 02-20-2013 at 07:38 PM. |

Starprobes
So, spending time watching Leonard Susskind's series from Stanford (long time past college physics for me), planning the next teacher workshop, and building give-aways for same.
Got to thinking about how to better tell a story with the displays. Not necessarily a realistic scene/diorama - but ya'll are a great source of inspiration. So here's our current lineup of spacecraft that are outbound: It ain't P-K but it might work ... Yogi added: 1:48 scale all; the Pioneer 10/11 is Ton's, the Voyager 1/2 mine (our download section), the New Horizon's is an enlargement of my Atlas V payload version (should be at ECardModels, but Vaugh Hoxie's version is a bit nicer - just uses more paper) Last edited by Retired_for_now; 03-13-2013 at 10:15 AM. Reason: model ID |

Nice clean build and also very funny. I'd like having one of those school bus rocket engines on my Volvo 240 one day. After I saw one of your earlier comparison bus displays, I wanted something similar on my shelves, too. I found a Dutch site which hosts simple but nice models of the types of buses they had around here in my region up til 15 years ago. I made two of them (a yellow and a red one) to let other people get that sense of scale with something familiar.

PK, you mean those ZWN Den Oudsten ones with the red seats? Those were the only busses I could sit in comfortably...

Over here in Grunn the GADO worked the region with these yellow ones, Chassis by Leyland, coachwork by Den OUdsten. There were several different types but this one was most common in my youth:
and if I recall correctly, they indeed had red imitation leather upholstery. In Grunn city there were those dark red buses with a different but also red interior, chassis made by DAF and Hainje made the coachwork. I still think those buses had some character. I don't really like the modern ones. I'm getting old. Or nostalgic. Okay, enough about earth rolling equipment. Let's go back to the space thingies! |

Yogi,
I've just received my first request to build some paper models for classroom use- Apollo CSM and LM. From your postings, I know that you do many builds for educators and have a question. Given that second-grade classroom is one of the harshest environments this side of space or the deep ocean, and that one drop of water can do significant damage to graphics, do you spray or seal the outside of your models in any way? If so, what do you use? I've been thinking about spraying them with Rustoleum crystal clear. I've used this on stomp rockets before with good results. Thanks, erik |
