There is no reason why R&D work on more advanced systems could not go on. But it is important to distinguish building a reliable and cost-effective launcher from doing R&D in advanced launcher technology. The two are not the same; indeed, they are incompatible. If we want something that works well and that has some chance of being cheap, we *want* technology that is old enough to have been debugged. >(Also, much of the Saturn would have to be redesigned ... Nonsense again. Almost nothing would need redesign; the only area I can think of where this would be beneficial would be the electronics. We'd need to redesign the *tooling*, and that would cause small changes in the design of the launcher, and much of it would have to be re-tested, but the basic design is not broken and does not need fixing. >...

Potential GIC Status: GREEN. The flare effects from the major X-class flare of 20 April failed to materialize. The window for potential geomagnetic storming has passed. As a result, the Potential Geomagnetic Storm Warning has been terminated. Geomagnetic activity is expected to remain generally quiet to unsettled for the next couple of days. Solar activity indices have been dropping rapidly over the last several days. In particular, the solar flux has dropped to a level of 146 on 23 April, which is the lowest level observed since 02 November, 1990. Major flaring is no longer possible from the few very weak regions currently visible on the solar disk. In fact, only minor C-class flaring and occassional subflaring appears possible. SIDs/SWFs are not expected over the next several days. Stable ionospheric conditions should prevail. HF and VHF propagation conditions will remain near normal over the next several days. No periods of degradation are anticipated. Auroral activity will remain generally dormant. ** End of Bulletin ** ------------------------------ Date: Tue, 23 Apr 1991 17:22:28 CDT From: REIFF@SPACVAX.RICE.EDU (Pat Reiff (713)527-8750-2650) Subject: Eclipse Trip to Mazatlan X-Vmsmail-To: SMTP%"space+@andrew.cmu.edu" For those who would like an "out of this world" experience, there still are a few spaces left on an eclipse trip to Mazatlan for which I am the science advisor. We leave July 9 from Houston (chartered nonstop flight), stay 3 nights at the (beachfront) El Cid Mega Resort; watch the eclipse from on the grounds of the hotel (5 minutes and 27 seconds of totality; more if you want to share a cab and go somewhere else); and return July 12. The cost is $599 each for double occupancy; $569 each, triple; $559, quad. Hotel, air (from Houston) and transfers to and from airport are included; meals and local travel are not. (Who wants someone else to arrange their meals in Mexico??) This is the cheapest such trip I've seen advertised anywhere, and the operator is working at virtually no profit (he upped the class of the hotel without increasing the price). The tour operator is experienced in arranging amateur astronomy travel; I went with them to Canada in '79 and was a guide to Australia for Halley's Comet in '86. They have also arranged eclipse trips to many other places. For information call George at Hanssen/Future travel (800)544-4988. In Houston call (713)480-4020 or 480-1988.

If there is shooting in the area and the rebels control the launch pad then they won't be able to provide decent service.

Of course, the last disruption in the Soviet Union because of political events lasted 70 years. I agree that nothing NASA is doing couldn't wait a couple of years (subject to launch windows). However, that is not what I am talking about. I would like to see an active US space program which produces a spacefairing civilization. To do this the Soviets are not reliable enough.

That is an interesting idea. If anyone knows any more about this, please say something. Is there any way to alter the VEEGA trajectory in such a way as to bring it back to Earth at a low enough velocity to drop it into Earth orbit for repair? I realize it probably wouldn't get back until 1998 if it's even possible, but we could then retrieve it, fix it, and re-launch. -- Michael Kent mvk@itsgw.rpi.edu McDonnell Douglas Rensselaer Polytechnic Institute St. Louis, Missouri Troy, New York Apple II Forever! ------------------------------ ReSent-Message-ID: Resent-Date: Tue, 23 Apr 91 15:12:40 EDT Resent-From: Tommy Mac <18084TM@msu.edu> Resent-To: space+@andrew.cmu.edu Date: Tue, 23 Apr 91 01:58:56 EDT Reply-To: space+%ANDREW.CMU.EDU@msu.edu From: space-request+%ANDREW.CMU.EDU%CARNEGIE.BITNET@msu.edu Subject: SPACE Digest V13 #442 Comments: To: space+@ANDREW.CMU.EDU To: david polito <15432DJP@MSU.BITNET>, Tom McWilliams <18084TM@MSU.BITNET> Re: r101 & R100's >> OK-- What in the world is R100 and or R101, Can you give any >> references where one could read up on them.
