This will allow it to be far more flexable and allow the design and production overhead costs to be amortized over more vehicles resulting is still lower costs.

Possible applications: construction, aerospace, temporary structures, etc. etc. etc. We have a patent pending on this structure. Question: Where do we go from here?

The Internet gateway is just an option. Internal communications is usually the main thrust. But this guy is apparently importing and redistributing UseNet conferences, too (like me!). As in many realms of human activity, "othernets" tend to attract people of like mind. Often, these networks are very private and "secured". This has both benefits and drawbacks. For example, an isolated sub-population often reinforces its convictions among themselves. Sometimes, they then go out headstrong and wreak havoc on the general public.

Many of them also do significant manuevering, albeit not quite this extreme. However, you shouldn't be afraid of "unsual" techniques. Be afraid of bad ones.

However, in most cases, the "some" people you refer to are a very small minority. In addition, this in no way validates or repudiates your argument on the benefits of the shuttle. The shuttle program has been facing these criticisms since even before it launched. They have not been created solely for the purpose of promoting another vehicle. >We cannot afford to confuse the US Congress with conflicting signals in >the space community. Oooh.

The hardware has been designed from the begining to be safe enough for human passengers. Some diagrams of the orbit capable vehicle show space for a pilot. The trajectories now being studied are restrained below 3G. I'm fairly sure this is a human factors requirment as most unmanned boosters have much higher accelerations and this restraint does have a significant impact on the capabilities of the vehicle. -- Josh Hopkins jbh55289@uxa.cso.uiuc.edu "Find a way or make one." -attributed to Hannibal ------------------------------ Date: Wed, 12 May 1993 21:51:02 GMT From: Josh Hopkins Subject: Soyuz and Shuttle Comparisons Newsgroups: sci.space khayash@hsc.usc.edu (Ken Hayashida) writes: >>>I had said that it >>>had delivered the most mass to orbit.

That argument should be made on the basis of the shuttle's inherent merit - not by picking a different system and attacking it. Note also that if DC fails, you will be right. It's impact will be smaller. But if it succeeds, the impact will be tremendous. It has the potential to totally outclass the shuttle. >As I said in my previous post, the issue is not mass to orbit. >Its really an issue of social impact, do you think that the shuttle >and the STS as a whole as made life in the US any better?

An operational DC orbital vehicle (which is very different from DC-X) will have the capability to take down as much as it brings up if for no other reason than as a safety issue.

Most of the mass of the orbiter is overhead. The meaningful comparison (insofar as simply counting kilograms is meaningful) is payload mass. The wings and tiles, for example, contribute absolutely nothing to getting the payload up there; they should not be counted as useful load. >I would appreciate it if someone would tally the total mass RETURNED >from orbit on a Soyuz vehicle versus the Shuttle.

Again, the really meaningful question here is how much of that mass is stuff that *wanted* to return. It's not zero, but it's not large either. It would be much better to leave Spacelab, for example, permanently in orbit. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Wed, 12 May 1993 20:28:04 GMT From: kjenks@gothamcity.jsc.nasa.gov Subject: Vandalizing the sky Newsgroups: sci.space I just came across this, and it seemed appropriate to our discussion. Notice the interest in space advertising as a potential market for launch services. I'm glad others share my view. AVIATION WEEK: U.S. CONSORTIUM TAKES MARKETING APPROACH TO LAUNCHER PROGRAM NEW YORK (MAY 7) BUSINESS WIRE - Aviation Week & Space Technology reports in its May 10th edition that five U.S. aerospace companies have joined to study a common commercial approach for a new launcher that could succeed America's current fleet of aging boosters. The companies, Boeing, General Dynamics, Lockheed, Martin Marietta, and Rockwell International, held a kickoff meeting for the joint effort in March, and received enthusiastic support from NASA Administrator Daniel Goldin when they brief him May 2. The five-company group wants to perform a four-month, $3 million major survey of the launch service market needs. This would be followed by an 11-month, $20 million phase involving the definition of launcher concepts and technology risks for a new vehicle. Company managers said the consortium's approach to the new launcher will differ in several aspects from previous efforts to develop launch vehicles. The group feels it can create a market by seeking out untapped applications, including space advertising, commercial mining of the Moon and asteriods, low Earth Orbit debris cleanup, nuclear waste disposal and other hazardous materials operations, meteor detection and deflection, low Earth orbit tourism and space-based entertainment/education. Other industry officials, however, questioned the need for new studies of the already well-examined launch services marketplace and wondered how the grouping's creation would affect the U.S. Air Force-led Spacelifter launch vehicle program. -- Ken Jenks, NASA/JSC/GM2, Space Shuttle Program Office kjenks@gothamcity.jsc.nasa.gov (713) 483-4368 "Good ideas are not adopted automatically.
