Well, here's a first cut. There is actually not all that much branching in the tree. I'm ignoring assorted trivia like sounding rockets. Redstone, a tactical ballistic missile, with three small solid upper stages became Jupiter-C and launched Explorer 1 and some others. (The "Jupiter-C" terminology is because it was testing components for the Jupiter program, and von Braun & Co. noticed that things marked "Jupiter" got higher priority at the Cape than things marked "Redstone".) Jupiter, an Army IRBM, acquired an upper stage or two and became the Juno family of space launchers, which saw a little bit of use. Don't know much about it. Long extinct. Atlas, the first US ICBM, was used as a launcher all by itself for modest low-orbit payloads, including Mercury. With the addition of the first US liquid-hydrogen stage, the Centaur, it saw heavy use for low orbit, high orbit, and planetary missions. Numerous variants have appeared over the years, with a steady trend to longer tanks and hotter engines. An earlier upper stage, the Agena, also saw use for modest planetary missions and satellites, notably military ones, and was used for a docking target on Gemini. Titan II, the second Titan ICBM (Titan I, despite the similar name, was an entirely different missile), also has seen use in various forms. One variant of it (slightly longer tanks than the ICBM, I think) launched Gemini. Both alone and with upper stages (notably Agena), it launched quite a few missions. The last Titan-Agena flew only a few months ago. Now that the Titan II ICBM force has finally been retired, the USAF is reworking a bunch of them into medium launchers. Titan III is a Titan II with two great big solid strap-ons. There were a number of different versions, notably IIIC (general heavy-load USAF booster), IIIM (meant to launch the cancelled MOL military space station), 34D (slightly upgraded IIIC), and IV (latest variant, longer SRBs and other small improvements). Current US heavy expendable. Various upper stages, notably Transtage (small liquid stage) and Centaur, were used. Titan-Centaur was used for Voyager, among other things. The latest versions now fly with the shuttle IUS or the intended-for-shuttle fat- tank Centaur as an upper stage. The USAF's Thor IRBM (which used some Atlas technology, notably engines) was turned into a small launcher with the addition of a modest upper stage. This went through a whole bunch of steadily-bigger versions, with tanks getting longer and fatter, engines getting hotter, and solid strapons (first 3, then 6, now 9, and they're getting longer and fatter too) added. Somewhere along the way it was renamed Delta. The Japanese H-1 is a Delta spinoff, incidentally, with a new liquid-hydrogen upper stage (which McDonnell Douglas would like to buy back except it's not for sale). The Scout is practically the only one of the bunch that isn't a missile derivative. Scout is four big sounding rockets piled up to make a very small satellite launcher. It too has grown a little bit over time. There were a vast number of proposed Saturn configurations, only three of which ever became real. The Saturn I had a first stage which was a massive cluster of Atlas/Thor engines and Atlas and Redstone tankage, plus a small upper stage that was sort of a fat Centaur with more engines. It was basically a dead end, in retrospect of no importance except for technology development for later Saturns. The Saturn IB used a stretched souped-up Saturn I first stage, plus the big S-IVB liquid-hydrogen upper stage of the Saturn V, for low-orbit Apollo launches and some other odds and ends. The Saturn V, despite the similarity in name, had nothing to do with the Saturn I. Three all-new stages with all-new engines. Intended for Apollo lunar missions, lunar bases, space stations, heavy planetary probes, etc etc. 15 built; 13 used, 2 rusting lawn ornaments. The Shuttle is another all-new launcher. Its SRBs are somewhat similar to the Titan ones, but many details are different and they are bigger. -- A bit of tolerance is worth a | Henry Spencer at U of Toronto Zoology megabyte of flaming. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: Thu, 16 Nov 89 19:10:38 EST From: John Roberts Disclaimer: Opinions expressed are those of the sender and do not reflect NIST policy or agreement.

I don't think there's any point along Mars' equator that Phobos doesn't eventually pass over, which would certainly affect the performance of the space elevator! :-) This problem was discussed in Fountains of Paradise by Arthur C.

M. Jungclas) Subject: "rec.models.rockets" PASSES with 180 margin - 196 YES to 16 NO! MANY THANKS TO THOSE WHO VOTED. An attempt was made to individually acknowledge each vote. A few of these were bounced back and I gave up after the second try. The voting period for the creation of "rec.models.rockets" ended at midnight (24:00) November 15th. A total of 212 valid votes, 196 YES (92.5%) and 16 NO (7.5%) votes were received within the specified time frame. (12.3 YES votes were received for each NO vote.) With a margin of 180 votes, the proposal easily PASSES indicating that "rec.models.rockets" should be created. A total of 5 INVALID VOTES, 4 YES and 1 NO, were also received and these are explained below. The list of voters is given below. >AFTER the vote result is posted, there will be a 5 day waiting >period during which the net will have a chance to correct any >errors in the voter list or the voting procedure. Since I'll be offsite from Nov 18 thru Nov 26, I will not take action to have the formal newgroup request sent out until November 27th. Please inform me of any irregularities/comments that you spot by then. COMMENTS: I am surprised on the size of vote turnout. I had expected a more marginal victory. The 100 vote margin was obtained on the 7th day of voting. The vote was taken under the OLD guidelines (30 day voting period.) (The vote was 187 YES and 15 NO after 21 days.) A comparison between this attempt and other new newsgroup attempts is given below. Only one vote was counted per email address (ie. duplicates & proxy votes were removed). As it turned out this applied only to YES votes. 24 (20 YES and 4 NO) votes were received before the official start of the vote (midnight (24:00) Oct 16th). These votes were NOT included in the above totals, but email was sent to EVERY voter and asked to re-vote. All but 3 voters (2 YES and 1 NO) recast their votes. The original call for votes just specified "midnight Oct 16th." There apparently was some confusion of whether midnight means 00:00+ Oct. 16th or 24:00- Oct 16th which I subsquently cleared up with later calls for votes. Webster's dictionary defines midnight as "12 o'clock at night" which is the meaning that I intended. The votes that were not included should be an issue since they help to establish a greater YES margin. One person changed his vote from NO to YES, but the YES vote was disallowed as it wasn't explicit enough. (Ie. empty email body, subject line just contained "YES" and there was no references to any newsgroups.) The net result is the NO vote is still included in the total above. Mail was sent to this individual asking him if he really intended to change his vote and informing him of his invalidated YES vote. No reply was received by the voting deadline. One YES vote was relayed through another login as the voter could NOT get mail directly through to me. Although this relayed mail clearly contained the voter's mail, the YES vote was INVALIDATED because it could be considered as a "proxy" vote. However, I did send mail to this voter and he was able to return mail by the deadline, so a valid YES vote was received.
