I normally rely on BurnTime MFD to tell me how much Dv a spacecraft can deliver, but I am currently stacking up some Velcro stages and BT MFD shows Dv for each individual vessel, without adding the mass of the stages attached above. (Clever Velcro does include the mass of attached vessels, so...

I wonder what the "fail-safe" is? Plain old radioactive fuel is easy to store, in theory (and pretty much in practice). And the chain reaction can be stopped by inserting control rods. I don't know the details, but I suppose this is a simple and fairly quick motor driven process, that can be...

Flyer, Glider, whatever -- it's always been just a trainer to me ;)

Interesting, but a little "iffy." I will definitely give this a try once my addon is up and flying. Hope it works with Spacecraft3 vessels. This all started when I decided to learn TransX and do slingshots. I was using Flytandem's tutorial, flying the Delta Glider on Voyager 2 timeline and...

Sputnik, For my Voyager addon, I am attempting to assemble a TitanIIIE entirely from Velcro parts. The Voyager has a propulsion module that I want initiated from the start. If the propulsion module is generated as a payload then the IMFD or TransX data guiding the earlier stages won't...

Excellent answers -- thanks for the replies. Sputnik, I have a Velcro question that I will post in you addon thread. Thanks

I am modeling a TitanIIIE (with Velcro rockets) to launch a Voyager addon I have in progress. I am running into a snag on the 5 segment solid rocket boosters (UA1205). As always, the numbers do not agree among various on-line sources, but they are close enough: Total Mass: 226,533 kg - 226,800...

With events like this, there is always an interest in working up the psychological/emotional profile of the shooter - and I am as interested as the next person. But I am also interested in the psychology of the (nominally) sane observers and general public. The anit-gun reaction seems...

I think Station Building Blocks includes a Propulsion Module. Becuse it is all done with Spacecraft 3 you can easily "goose" the thrust. To increase available burn time, increase the fuel mass or the ISP. Just use a text editor to open the appropriate .ini file in the Config\Spacecraft...

I find that the SIZE parameter in SC3 relates the the distance at which a vessel is seen when it is first generated - as when a Spacecraft3 vessel is jettisoned as a payload. By making the various parts the same SIZE you can minimize camera jumps as Orbiter shifts focus from a spent booster to...

I vote Apollo 13 because the attention to realistic technology was about as good as Hollywood ever gets it. Just as important (because it is a movie) are the high production values -- even though everyone knows how the story turns out, the writing, performances and camera work generate tension...

You can also learn more by looking at other addons. BrianJ is my multistage guru. He has gotten into some custom .dll in his most recent addons, but the bulk of them are SC3 and MS2. http://www.orbithangar.com/search_quick.php?text=BrianJ I used multistage for launching MER and Skylab, but...

Very nice! It is exciting to release your first addon. Your lander really does have a 1950s, NACA, speculative, pre-Apollo look - I like that. (Might need a little more Victorian gingerbread to be H.G. Wells, IMO. Not to mention tenticles and a heat ray.) What was you inspiration? Make no...

Kids say the darndest things. And I learn the darndest things on this forum!

Thank you Brits! But alas... all bollix. (However that's spelled, and whatever it means, exactly.) I ran into the Unmanned Spacecraft forum early in my searches and got some good leads on graphics, photos and various odds and ends, but not much about launch day. One of the postings gave...

I am having a devil of a time finding detailed information on the Voyager 1 and 2 launches. Voyager 1 was lunched September 5, 1977. This web page from the National Space Science Data Center gives some good details on Voyager's interplentary trajectory...

Touche' mon ami! You win... well played. Praise the Lord and pass the hydrazine!

Certainly anyone who "plays" with Orbiter must know that anything resembling Battle Star-Trek-Wars-Gallactica dogfighting or capital ship maneuvers and bombardment is out of the question. The only things in space worth fighting over are planetary systems, and within planetary systems the effects...

As I was saying, lots of planets but few photos of the spacecraft. I complain only as a spoiled Orbiter add-on developer. Actully, it is refreshing to see a NASA mission in which science so completely overwhelms the engineering and the personalities. Although I have seen these spacecraft...

I am working on a new add-on for the Voyager missions. (That is to say, JPL's real-life twin probes to the outer plantes - not Capt. Janeway's fictional Star Trek command. Then again, V'ger... bu I digress.) The on-line photos and technical info is remarkably sparse. NASA's and JPL's web pages...
