In case one has a stuck antenna, like one we have en route to Jupiter. Then one can relay data from the other. Or a dead high power transmitter, or a deaf receiver, and such. I suppose that someone has figured out what design to change, or do better, to avoid "stuck antenna" problems? ========================================================================= Are banana peels considered hazardous waste (after all, someone could slip on one and fall)? ------------------------------ Date: Wed, 9 Sep 1992 03:31:14 GMT From: Dave Tholen Subject: Pluto Direct/ options Newsgroups: sci.space Ron Baalke writes: > The launches of the two spacecraft will be staggered by 3.2 > days to allow observations of both sides of Pluto and Charon. Actually, the launches don't have to be 3.2 days apart. You can easily adjust the arrival times enroute. Also, it is quite likely that the arrival times would be perhaps as much as a year apart, though still designed to image the opposite hemisphere. The reason for the delay is to permit the data from the first encounter to be played back and analyzed before designing the details of the second encounter. The bit rate is quite low in the current design, so playback could take several weeks. ------------------------------ Date: 9 Sep 92 03:24:50 GMT From: Dave Tholen Subject: QUERY Re: Pluto Direct/ options Newsgroups: sci.space Tom A Baker writes: > Could you clarify whether this craft is supposed to just flyby (a la > Voyager) or is truly a Pluto "orbiter"?

Although an orbiter has been discussed, the current mission design calls for only a flyby. To go into orbit, you need to travel more slowly, thus flight times are longer. And you need to carry more fuel, which impacts the size of the instrument payload. All kinds of tradeoffs. ------------------------------ Date: Wed, 9 Sep 1992 01:43:57 GMT From: Tom Utiger Subject: SSTO motors Newsgroups: sci.space ------------------------------ Date: 9 Sep 92 02:59:16 GMT From: David Palmer Subject: Truax Newsgroups: sci.space al@sys6626.bison.mb.ca (Haus Der Luge) writes: > >Is there anybody using this sub-board who is at all familair with the >work of one Bob Truax ??? > >From what I've heard, he's quite the "space ranger". A good book is 'Great Mambo Chicken and the Transhuman Condition' by Ed Regis (Addison Wesley, ISBN 0-201-56751-2). This is a book about visionary scientists and engineers.
