Yee) Subject: McBride to leave NASA; Brand named commander of STS-35 (Forwarded) Sarah Keegan Headquarters, Washington, D.C. April 24, 1989 Jeffrey Carr Johnson Space Center, Houston, Texas RELEASE: 89-62 MCBRIDE TO LEAVE NASA; BRAND NAMED COMMANDER OF STS-35 Astronaut Jon A. McBride (Captain, USN) has announced his intention to leave NASA effective May 12, 1989. McBride was named last year to command the STS-35 (ASTRO-1) mission, scheduled for launch in March 1990. He will be succeeded as STS-35 commander by Vance D. Brand. McBride was selected as an astronaut in August 1978. He was the lead T-38 chase pilot for STS-1, the maiden voyage of Columbia in April 1981, and a Capsule Communicator (CAPCOM) in the Mission Control Center for Shuttle flights STS-5, STS-6, and STS-7. He flew in space as pilot aboard Challenger on STS 41-G in October 1984. McBride was scheduled to fly next in March 1986 as the commander of STS 61-E. The flight was one of several deferred by NASA in the wake of the Challenger accident in January 1986. McBride recently completed an assignment at NASA Headquarters, Washington, D.C., as the Acting Assistant Administrator for Congressional Relations, a post he held since September 1987. He has also announced his intent to retire from the Navy in the near future. McBride said, "I've spent an extremely rewarding 25 years with NASA and the Navy. This move has been a very difficult decision for me. But in the final analysis, I felt it was time to make a career change and return to West Virginia. I'll continue to follow developments in the space program with keen interest". Brand joined NASA as an astronaut in 1966. He flew as Apollo command module pilot on the Apollo-Soyuz Test Project mission in 1975. Brand has also flown as commander of Shuttle missions STS-5 in November 1982 and STS 41-B in February 1984. Brand currently serves as JSC's Assistant Manager for Space Station Integration and Assembly. He was born on May 9, 1931 in Longmont, CO. ------------------------------ Date: 24 Apr 89 05:01:39 GMT From: mailrus!jarvis.csri.toronto.edu!utgpu!utzoo!henry@tut.cis.ohio-state.edu (Henry Spencer) Subject: Re: Proposed lunar simulation facility In article <1253@l.cc.purdue.edu> cik@l.cc.purdue.edu (Herman Rubin) writes: >> >>Los Alamos proposes to build a lunar-surface simulation facility for >> >>testing lunar mining and construction hardware... >> >Is that a computer simulation testbed, or an actual physical construction >> >to emulate the lunar terrain? >> The latter, complete with vacuum chamber etc. > >And I suppose they will manage 1/6 g also?

They can't get genuine lunar soil in that quantity, but its mechanical and chemical properties are well enough understood to do a plausible simulation, I would think. Dryness will not be an issue in vacuum. >There are construction and mining techniques which can be used in 1/6 g which >cannot be used in 1 g and vice versa. It is not just the vacuum. Agreed. Given the impossibility of testing such techniques on Earth, they probably will not be used in any first-generation lunar facility. Methods that can be tested will be used instead.

What if the other person in town is deaf, or frightened of loud sounds? On the other hand, by broadcasting not to those who are parallel to us, but to those who have yet to observe the given event, chances of reception are greatly increased. If we assume (that dangerous word again!) that by the time we have registered the event as occuring and started transmitting is the same time interval which an alien system would experience (and there is not evidence to refute that :-)), then the following scenerio might take place: "Look Dr. Bloop, a supernova!" "Quick, point everything we have at it" next day "Now we are receiving some sort of binary encoded transimission, maybe there is another intelligent lifeform out there! Quick, send the Beserkers!" (Sorry, I just had to) The other alternative would be some sort of man made event. My office mate suggests blowing up the sun, but I think that as a little drastic. The only real requirements would be that it is detectable at some extreme distance (25,000 ltyrs?) and obviously artificial. Making the sun nova would fit this, but what could we do within current (or near term) technology? I still like my nucleat flare gun, but suspect it a little short on the range. Comments?

You will find cogent arguments about some negative aspects of the manned space program in a Scientific American article authored by James Van Allen (yes, _that_ Van Allen). The issue appeared a few months (six?) prior to the Challenger disaster (I'm sorry I can't be more specific). As to the "beneficial spin-offs" argument, I belive a study by the Office of Techology Assesment found that direct funding of technology was three times as efficient in generating results for a given amount of investment than the spin-off phenomena.

Eric Weisstein ------------------------------ Date: Tue, 25 Apr 89 9:47:44 CST From: Will Martin -- AMXAL-RI Subject: Re: US citizen - ET contact legal penalties Hi, all! Just caught up with the last 15 or so Space Digests, and noted the discussion about the NASA regulations on ET contact; so I went down to the library and got out 14 CFR Part 1211 and herewith is the first part of that. I'm not typing in a lot of this; CFR's are in most public library systems and are fairly readily available. Also, most of it isn't really of much interest. The relevant section is on pages 115 thru 118 of the volume of 14 CFR that has parts 1200 to the end of that segment. This is the edition as of 1 January 1988; it has purple covers. (The CFRs are issued in a staggered form throughout the year, as the editing is completed. Not all the 88 issues are yet out, and 89 hasn't begun yet. The previous 87 issue has green covers; the colors change each time so you can glance at the shelves and see which have been updated and which have not yet been reissued.) ***Begin quote from CFR*** 14 CFR 1211 Sections: 1211.100 Scope 1211.101 Applicability 1211.102 Definitions 1211.103 Authority 1211.104 Policy 1211.105 Relationship with Departments of Health, Education and Welfare and Agriculture 1211.106 Cooperation with States, territories, and possessions 1211.107 Court or other process 1211.108 Violations 1211.100 Scope. This part establishes: (a) NASA policy, responsibility and authority to guard the Earth against any harmful contamination or adverse changes in its environment resulting from personnel, spacecraft and other property returning to the Earth [Note -- my emphasis here -----> ] ^^^^^^^^^^^^^^^^^^^^^^ after landing on or coming within the atmospheric envelope of a celestial body; and (b) Security requirements, restrictions and safeguards that are necessary in the interest of the national security. 1211.101 Applicability. The provisions of this part apply to all NASA manned and unamanned space [Note -- my emphasis here -----> ] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ missions which land on or come within the atmospheric envelope of a celestial body and return to Earth. ***End of quote from the CFR*** (Those two sections are complete, though.) The next two pages concentrate on quarantine details and general legalese. One paragraph clearly states that all persons quarantined are to be allowed to contact their legal representatives as soon as possible, so the implications in other postings of being held incommunicado are not all that likely. (Still *possible*, but it would be against the regs, for what that's worth... :-) Anyway, note the portions I emphasized above. This specifically does NOT apply to ETs coming in from outside, but only to NASA missions. If you read just the first paragraph, though, you *could* say that this will apply to the Second Coming... :-) [They'd have a hard time establishing jurisdiction in that case, I suppose...] The other aspect of this that I find interesting is what may be interpreted as the "we are the cops of the world" attitude in the reference to "guard the Earth", not "the nation" or any other limiting term. I doubt that phrasing is used anywhere else in the CFRs... Not that I disapprove -- it is a realistic attitude, after all. Another odd coincidence is that I noticed a copy of "The Andromeda Strain" on the paperback-exchange rack right by the CFR's as I was doing this... :-) Mayhap this info will put the speculation to rest...
