Thompson said that he had requested James T. Rose, the NASA Assistant Administrator for commercial programs, to study using up to half of the Space Station Freedom volume for commercial programs. Up to this point, volume in SSF had not been allocated for commercial payloads. This internal NASA request was made some months ago, before the SSF redesign effort, and was initially designed to see what commercial applications, if any, could be hosted on SSF. This caused some concern among the scientists on the advisory committee, who expressed concern that science payloads might have to compete with commercial projects for the limited volume in a redesigned, smaller space station. In particular, displeasure was expressed that the scientific payloads had to go through cycles of peer review to judge their merit, and then would be judged again against commercial payloads, which might have had less review on their merit. [Commentary: It's past due for NASA to begin to think about how commercial firms can use SSF. The science folks are justifiably concerned their precious space on board SSF is going to be shrunk even more. Last I heard was that volume on the SSF was very, very tight just to fit in all of the stuff planned -before redesigning and shrinking the volume. NASA really needs to look to see what they can do to encourage commercial use of any Space Station, and while it's a useful exercise, I really don't see anything substantial coming out of this - yet. I don't think commercial users will use up to 1/2 of SSF, even with the latest SSF redesigns which was rumored shrink the available volume by 1/2. The market projections which were done for Congress on ISF (a small man-tended Space Station proposed to Congress as an entrepreneurial venture), pointed out that 90% of available market for a similar system was governmental in nature, the purely commercial market was fairly small with several competing systems to do the same job, and it was doubtful that enough users could be found to fill a small (1 module) man-tended space station. I don't think the market has changed sufficiently to generate enough new business that would want to go onto SSF to fill 1/2 of it up. There have also been some concerns raised that SSF's microgravity environment also would not be suitable for long-term materials processing in space - one of the suggested areas for commercial use of SSF - which would tend to reduce the commercial usage expected. It will be interesting to see what Jim Rose's reply on commercial use of SSF will be...] -- Wales Larrison Internet: Wales.Larrison@ofa123.fidonet.org Compuserve: >internet:Wales.Larrison@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Date: 1 Mar 91 20:44:04 GMT From: world!ksr!clj%ksr.com@uunet.uu.net (Chris Jones) Subject: Re: chimps in space -- question In article <1991Mar1.190836.10028@uokmax.ecn.uoknor.edu>, jabishop@uokmax writes: >acsls@jetson.uh.edu (Eddie A.

I wasn't going to talk dogs, since the original poster asked about chimps. However... Sputnik 2 carried Laika, who was not recovered. Korabl Sputniks 1 through 6 were unmanned tests of the Vostok capsule. (Sometimes they are numbered Sputniks 4 through 9). KS 2 carried the dogs Strelka and Belka; they (along with rats and other biological cargo) became the first living creatures from earth to orbit the earth and return. KS 3 also carried two dogs (Pchelka and Mushka, I recall, but I'm not sure). They perished when their capsule was destroyed during reentry. KS 4, 5, & 6 each carried one dog, and all were successful flights. There was one launch failure of a Vostok precursor with a dog or dogs on it; the Soviets say it was recovered after the failure. These flights took place during 1960-1961 (except Sputnik 2 was launched in November 1957). -- Chris Jones clj@ksr.com {world,uunet,harvard}!ksr!clj ------------------------------ Date: 1 Mar 91 13:02:38 GMT From: world!ksr!clj%ksr.com@uunet.uu.net (Chris Jones) Subject: Re: chimps in space -- question In article <1991Feb26.170300.164@husc3.harvard.edu>, millgram@husc4 (Elijah Millgram) writes: > >Can anyone tell me about instances of chimpanzees >being sent into space (name and date of mission, >purpose and results of mission, name of chimp, etc.)?

Substitute "manned space" for "space" and I might believe you, but I see no sign of such a decision ever having been made. I'm curious as to what you meant here. Decisions to make military role less overt have been made, e.g higher classification of spy satellites under Kennedy, but an overall demilitarisation is a different thing entirely.

If you select the historical facts to prove your thesis, that is. Nobody disputes that teleoperation works effectively for missions that just fly around and snap pictures. It becomes more doubtful for real-time interaction with a planet's surface, especially at the other end of long communications delays. >... for example, Voyager has by rough estimate generated 10 >times the references in the scientific literature for 1/50 the cost of >Apollo: a factor of 500 more useful to our knowledge base per dollar. Gregor Mendel's work was clearly far more useful to science than Voyager's, at a miniscule fraction of the cost, so clearly we ought to abandon space exploration altogether. This sort of apples-vs-oranges comparison does not help your case, Nick, unless you are much more specific about what *kind* of knowledge base you're after. Voyager did the easy part: fly past and look. Long ago I saw a cost estimate for getting Apollo-equivalent results using the Soviet Luna unmanned sample-return technology. It was pretty much based on guesswork in a number of ways, but it concluded that Luna cost as much or more if you insisted on getting the same results. If you were willing to change the specs, then it was easy to change them so that either approach came out far ahead of the other. >Another way to look at it: Voyager explored four planets and dozens of >moons, while discovering over a dozen new moons.

Well I don't see any reason they should hang around and wait. The LLNL bases are light and cheap. If after exploration they find it should be somewhere else, then they can either put up a new base or move the one they have. Besides, I think having humans on site working with LO would be a very powerful combination. On the other hand, if all goes well the most important information may already be known if Lunar Prospector is launched on schedule.

The Bush Administration is again asking Congress to reinstate a permanent tax credit for research and experimentation. This was revealed in testimony to the House Science, Space, and Technology Committee on 20 Feb by the President's Science Advisor Dr. D. Allan Bromley. The current research tax credit must be renewed by Congress annually, which Bromley claimed reduces the ability of corporations to plan and invest in R&D due to the added uncertainty. [Commentary: The R&D tax credit is important to increasing the private funds available for space development. Orbital Sciences Corp, for example, was founded using this mechanism to attract investors. This tax credit is very important in ensuring investment in new space ventures, and other mechanisms to increase the funds available to research commercial products and processes in space should be encouraged. I think this is also part of the Omnibus Space Commercialization Bill (for space ventures only) to be reintroduced in the House this year. Making it a permanent fixture would be a good idea - so write your Congressperson!] ARIANESPACE RESCHEDULES LAUNCHES DUE TO ENGINE TEST FAILURE The next Ariane launch wasbe delayed until 1 March due to the failure of one of its cryogenic 3rd stage engines in a ground test. On Feb 12th, one of the 3rd stage engines was being test fired as part series of tests at the SEP (Societe Europeenne de Propulsion) test facility in Vernon, France. Apparently, the engine failed when tested to the limit of its expected operational envelope. The press statement released by Arianespace didn't indicate the nature of the malfunction. Arianespace reported further checks of the engine's start-up sequence checkout, the operating margins were still O.K., and rescheduled the launch. The delayed Ariane 44LP rocket flight was manifested to launch the ASRA-1 satellite (Luxembourg international direct TV broadcast satellite) and the Meteosat-2 satellite (ESA GEO weather satellite). [This was evidently a failure while testing the engine in "off- nominal" conditions. Even though they were testing the engine's operations under conditions they don't expect to see in flight, they saw a failure occur when one wasn't expected, and it was very appropriate to put the program on hold until they figured out why the failure happened. Arianespace is very sensitive to this type of failure, as they lost a couple of early launches due to problems with the propulsion system - which were also unexpected after successfully completing the engine test program. Here, they were being appropriately cautious about not risking their customer's satellites.] -- Wales Larrison Internet: Wales.Larrison@ofa123.fidonet.org Compuserve: >internet:Wales.Larrison@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Date: Fri, 1 Mar 91 21:43:34 EST From: John Roberts Disclaimer: Opinions expressed are those of the sender and do not reflect NIST policy or agreement.
