I guess this is the right part of the forum to ask questions, so here's another one; Which were the main contractor firms for the Mariner 9 spacecraft (which firm built the thruster, radios and electronics)?

Have a look at: http://www.astronautix.com/craft/marner89.htm The spacecraft itself was built by JPL. Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Quiet a difficult question!
Searched in my books and couldn't come up with an answer and although the Mariners were built in-house at NASA-JPL, following contractors helped on Mariner 6 & 7: TRW (Thompson - Ramo - Wooldridge ) for the propulsion Honeywell for the attitude subsystem Philco-Ford for the radio Motorola for the central computer and sequencer subsystem Litton Systems for the Data storage Texas Instruments for the Telemetry ... Well, now I'm curious to see such a list for the Mariner H ( 8 ) and Mariner I ( 9 ) spacecraft

Still trying to find the answer, challenging question as I said
 Only found so far that NASA asked Boeing Aerospace, General Electric and TRW to work on a spacecraft in 1966 ... Didn't even find an answer here:  http://www.hq.nasa.gov/office/pao/History/SP-4212/ch6.html nor here: http://www.jpl.nasa.gov/releases/70s/release_1971_0595.html  While here it just says Prime Contractor: In-house http://history.nasa.gov/SP-4012/vol3/table3.118.htm |

Don't count on the Internet too much ( except UnmannedSpaceflight.com of course
 ... )A good source is ntrs.nasa.gov But I really prefer to search in my collection of books, here's part of that collection: http://www.boggsspace.com/jpl_tech_reports.htm |

Now this is a real fusion of art and science:
http://beacon.jpl.nasa.gov/Histphotos/hpom/312-159bc.html Trajectory Design Model Photograph Number 312-159Bc "Ever try to shoot a slow flying duck while standing rigidly on a fast rotating platform, and with a gun that uses bullets which curve 90° while in flight?" This question appeared in the July 1963 issue of Lab-Oratory, in an article about spacecraft trajectory design. During mission development in 1967, the trajectory design model shown above allowed Mariner Mars mission planners to illustrate the orientation of the planet, the expected path of the Mariner 6 and 7 spacecraft, and the window of opportunity for the instruments and TV cameras to operate during the flyby. Today, computer generated plots and computer animations are used to present the same information. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
