I think a distinction needs to be made here. The problem is not protectionism per se, but rather preventing the exportation of high technology to foreign governments, especially Russia, which is our leading competitor (right now). Not only in terms of launch costs, but politically and militarily, too. There is certainly the possiblity that this is just a fancy justification for protectionism, but until launch costs get low enough to make launching non-high technology wothwhile, we'll never be able to test the theory. If I remember right, G.M. was petitioning congress at one point to allow the export of a satellite to Russia for launch, since they were so much cheaper. I think the end result was that they had to cover it up in a Gov. approved way, to prevent the dirty ruskies from learning how MTV works. I'm sure it wasn't a regular broadcast bird, but they were allowed to do it. I don't have references, at least not good ones. Anyone want to give me a reality check?

Costs should also be pretty much the same or less - and I think that the government could fund two launch teams into a "launch off" of competing prototypes for about the same money. (This would probably require some coordination between the two systems to allow them to use the same basic launch facilities, though - a good role for the government). This would also encourage the competing teams to consider commercial applications - as a backup if they should lose the competition, and to figure out faster, better ways to recoup their prototyping costs. But I am not impressed with the commercial prospects for the NLS. It's another system designed by the government, built by the government, to be operated by the government, for government needs - and giving lip-service to kluging a "commercial version" is only political maneuvering. Let's get real, folks.] SOVIETS MAY BUY WESTERN COMSATS In a rather surprising development, representatives of the Soviet Union are reported to be checking out the possibility of buying Western hardware as the basis for a new Soviet domestic satellite communications network. Apparently, the Soviets have approached two firms in Germany and Spar Aerospace in Canada to act as suppliers for a proposed new Soviet Ku-band domestic network known as "Romantis" This system would be coordinated by a Soviet entity called Informcosmos. As proposed, Glavcosmos and Intersputnik would consult to this organization (of Soviet communications bureaus), installing western Ku-band transponders on Soviet satellites (previously's Intersputnik's responsibility) and launching them on Proton rockets (presumably Glavcosmos' responsibility). Up to 300,000 ground stations have been proposed to link with this system, and the Canadian and German firms approached have also proposed to provide these as part of the package (or provide the technology and expertise for them). Key issues still be resolved with this venture include the split of who builds what ground stations with whose technology, technology transfer issues under COCOM restrictions on space hardware transfer to the Soviets, and Soviet payment in non-convertible currency. Current turmoil in responsibility between the Russian Republic and the central Soviet government have also complicated this issue. [An interesting development with interesting ramifications - but one which will probably not pay off for some years. This Soviet business venture is even more speculative than average since the Soviets have been very proud of their space hardware expertise, and have been trying to sell their communications satellite technology on the world market. Buying western hardware or technology will soak off hard-to-find hard currency, and is a challenge to the Soviet space bureaucracy. Adding the current confusion in Soviet vs Republic responsibility means it will be difficult to find anyone with the resources and authority to approve and fund such a system. Also, the Soviets have in the past been very insistent in providing their own satellite systems, including forming a competitor to the Intelsat international telecommunications system called Intersputnik which used all-Soviet hardware. This program would be the death knell for Intersputnik.] -- Wales Larrison Internet: Wales.Larrison@ofa123.fidonet.org Compuserve: >internet:Wales.Larrison@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Date: 1 Apr 91 03:49:14 GMT From: agate!bionet!uwm.edu!wuarchive!usc!elroy.jpl.nasa.gov!zardoz.cpd.com!dhw68k!ofa123!Wales.Larrison@ucbvax.Berkeley.EDU (Wales Larrison) Subject: Commercial Space News (1 of 5) This is the sixth in an irregular series on news from the commercial space business.

As described by OSC, the ORBCOMM-X satellite is about 35 lbs in weight and use about 8 watts of power. It is planned for launch as a "hitchhiker" smallsat payload on an upcoming Ariane-4 launch in May. The Ariane will deploy the ORBCOMM-X satellite into a polar orbit of about 480 miles altitude while inserting another polar orbiting satellite. The ORBCOMM-X satellite will demonstrate the capability to receive a communications from its ground station in Virginia, store it, and then retransmit it to the ground on its next pass. This will demonstrate prototype operations for a proposed network of 20 similar satellites to provide continuous data communications, messaging, and position determination to customers worldwide. [Commentary: OSC has had a division of its organization working on this small communications satellite for some time. This system can be seen as two things - a potential competitor to the Motorola Iridium system, and as a potential competitor to Geostar/Locstar, It should be noted that the proposed OSC system would not provide the cellular phone service that Iridium would provide, but would compete directly with the Geostar system. As Geostar has run into financial problems, this system might have some attraction for the U.S. market, but between Locstar in Europe, and other competitors entering the market in the U.S., it might find hard going to enter into these markets. Similarly, Iridium has the ability to preempt much of this market - if they can lock up the international market through the international consortium they are rumored to be trying to construct for the Iridium system. However, the ORBCOMM system would require less orbital frequency spectrum, and might be a little easier to sell on the international market. But it would not offer the same services as Iridium. Either way, this would only influence a future business area for OSC, and the jury is still out on both systems. It should also be noted the Soviet Union has also offered to sell a polar-orbiting store/dump communications satellite system at bargain basement prices. I don't believe this system offers the same capabilities as advertised for the OSC ORBCOMM system or the Iridium system, but it has the advantage of being proven in service. A similar (identical?) system is used for USSR global military and intelligence communications, and a constellation of satellites is on orbit (they are not for sale). There have been no takers for this system yet, but the satellites (and presumably launch services for them) are now for sale on the market.] -- Wales Larrison Internet: Wales.Larrison@ofa123.fidonet.org Compuserve: >internet:Wales.Larrison@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Date: 2 Apr 91 16:25:51 GMT From: agate!bionet!uwm.edu!rpi!news-server.csri.toronto.edu!utzoo!henry@ucbvax.Berkeley.EDU (Henry Spencer) Subject: Re: Commercial Space news (5 of 12) In article <10233@hub.ucsb.edu> 3001crad@ucsbuxa.ucsb.edu (Charles Frank Radley) writes: >The US doesNOT believe in fair open markets.

This brings up a question I've been wanting to ask: Namely, how much are parts like this interchangeable? Is your standard Delta or Titan a made-to-order unique vehicle, or are there certain things that are more or less off-the-shelf parts. Could you get an engine assembly from Engines 'R' Us, mate it to an third-party fuel tank and then wrap your own external skin around it? I realize avionics are pretty specific and probably wouldn't apply here, but I am curious about the other items I mentioned above.

The first Shuttle designs where also simple designs with a goal of $300/lb to LEO. It was later when they (the various committees involved in specifying Shuttle requirements) made it complex. Look at it this way, think of all the reasons the Shuttle ended up the way it did. All of those reasons are still valid today. The Shuttle budget sank and we are in even deeper budget problems now. The Shuttle was designed by a committee and so is ALS. Nothing has changed and therefore ALS will fail for the exact same reason the Shuttle failed. A heavy lift vehicle would indeed be a nice thing to have. However we have better designs available today. These launchers could be available in less than half the time for 5% of the development cost of ALS. These are the systems we need to buy (not develop, buy). The effort on ALS so far has demonstrated that we have not learned anything from the history of launcher development in the US. It therefore seems that we are doomed to repeat it.
