Any indication of strength? Electricial resistance? (for reasons I don't understand, articles about Buckyballs and -tubes always mention superconductivity.) How about bendability? It seems to me that one step toward a macro structure could be "Buckyrings" in which Buckytubes are bent into a circle and joined at the ends (emitting Buckyballs), but also woven together like chain mail to form sheets. The sheets could then be formed into tubes, the tubes bent into rings, etc. etc. I have a bit of a personal interest; I met Bucky in 1979 and we discussed the possibility of carbon atoms forming geodesic structures. I don't think we called them "Buckyballs" then, but when I heard the term a year or so ago, I knew immediately that that was what they were. Suppose we came up with a (Buckytube-based) material strong enough to make an Earth beanstalk, and it could be manufactured in mega-kilo lots for pennies per kilo. How could we use it to get into space? Is there any small-scale, bootstrapping approach that avoids involvement with Big Dump Organizations like NASA and the US Govt.?

On August 7, the final portion of TCM-14 (Trajectory Correction Maneuver #14), TCM-14D, was performed consisting of one small (0.4 m/sec) axial burn followed by a three segment lateral burn of 2.3 m/sec. The spacecraft performance throughout the maneuver activity was normal and near expected levels. In particular, the RPM (Retro-Propulsion Module) tank pressures and temperatures were normal throughout the four burn segments. Radio navigation data after TCM-14D indicated about a 1.3 percent overburn. The integrated 4-portion overburn was about 1.4 percent. 2. On August 7, the EE-7 (Earth-Earth 7) sequence memory load was uplinked to the spacecraft. This sequence covers spacecraft activities from August 10, 1992 to November 23, 1992. The sequence was loaded on the spacecraft without incident. 3. On August 10, a NO-OP command was sent to reset the command loss timer to 264 hours, its planned value for this mission phase. 4. On August 10, the Energetic Particle Detector (EPD) was returned to Sector 4 from Sector 0 after the completion of TCM-14. The EPD instrument was placed in Sector 0 for TCM-14 because it was the predicted least contamination position for the maneuver. 5. The AC/DC bus imbalance measurements exhibited some change. The AC measurement increased 1 DN and reads 3.3 volts. The DC measurement has ranged from 103 DN (11.9 volts) to 160 DN (18.9 volts) and now reads 127 DN (14.9 volts). These measurement variations are consistent with the model developed by the AC/DC special anomaly team. 6. The Spacecraft status as of August 13, 1992, is as follows: a) System Power Margin - 70 watts b) Spin Configuration - Dual-Spin c) Spin Rate/Sensor - 3.16 rpm/Star Scanner d) Spacecraft Attitude is approximately 6 degrees off-sun (lagging) and 40 degrees off-earth (lagging) e) Downlink telemetry rate/antenna-40 bps (coded)/LGA-1 f) General Thermal Control - all temperatures within acceptable range g) RPM Tank Pressures - all within acceptable range h) Orbiter Science - UVS, EUV, DDS, MAG, EPD, and HIC are powered on i) Probe/RRH - powered off, temperatures within acceptable range j) CMD Loss Timer Setting - 264 hours Time To Initiation - 184 hours TRAJECTORY As of noon Thursday, August 13, 1992, the Galileo Spacecraft trajectory status was as follows: Distance from Earth 97,738,600 miles (1.05 AU) Distance from Sun 156,757,800 miles (1.69 AU) Heliocentric Speed 49,700 miles per hour Distance from Jupiter 660,750,900 miles Round Trip Light Time 17 minutes, 38 seconds SPECIAL TOPIC 1. As of August 13, 1992, a total of 8109 real-time commands have been transmitted to Galileo since Launch. Of these, 3231 were pre-planned in the sequence design and 4872 were not. In the past week, 1 real time command was transmitted and pre-planned in the sequence design. In addition, 5427 mini-sequence commands have been transmitted since March 1991; 3269 were pre-planned and 2158 were not. In the past week, no mini-sequence commands were transmitted. Major command activities this week included commands to reset the command loss timer. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | You can't hide broccoli in /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | a glass of milk - |_____|/ |_|/ |_____|/ | anonymous 7-year old. ------------------------------ Date: 14 Aug 92 15:37:58 GMT From: Bill Higgins-- Beam Jockey Subject: He3 Power Source references Newsgroups: sci.space In article <1992Aug13.190624.1512@cbfsb.cb.att.com>, eatlv@cbnewsg.cb.att.com (thomas.vandoren) writes: > One of them was about a proposal to use Helium3 mined from the moon as a power > source on Earth.

The International Astronautical Federation is a collection of spaceflight professional groups from most of the countries of the world. It holds the biggest space conference of the year (this is the 43rd), at least on *this* planet. It moves around from city to city and it's in DC this year, at the Washington Convention Center downtown (as well as teh Ramada Renaissance Hotel and the Grand Hyatt Washington. It's a joint meeting with COSPAR, the Committee on Space Research, about which I know less, but apparently it's the great space science confab. The dual meeting is known as the World Space Congress. Of course there are oodles of presentations on all aspects of space science, astronautical engineering, space law, space education, remote sensing, etc. It's being administered by the AIAA. The hotline for registration info is (202)646-7569. Fees are now $300, unless you can prove you're a full-time undergrad or graduate student, in which case it's $30. The congress runs from 28 August to 5 September, with most action happening on the weekdays. Everybody in the space biz will be there, including lots of bigshots from all countries. I just met a couple of Mir cosmonauts who are touring the country before they attend WSC. I'm reading a paper on the morning of Friday the 4th, in the "Communicating to the Public" session, on creating the Usenet FAQs for sci.space. (Jon Leech, my coauthor, won't be able to make it.) Because the WSC is so big, other groups are having meetings clustered around it. Students for Exploration and Development of Space are meeting at the Quality Hotel the weekend of the 28th. I bet Lisa Weigel would tell you about it if you sent a request to alweigel@athena.mit.edu; also, stuff has been posted to the SEDS-L list-- look in the archives. The Association of Space Explorers (astronauts and cosmonauts) is meeting for a few days ending the 28th. The Congress includes various receptions held almost every night at museums, embassies, etc. The Planetary Society is sponsoring a bunch of stuff: A "road rally" for Mars rover vehicles on the Mall the 1st and 2nd (free admission, 10 AM to 6 PM, near the National Air and Space Museum). They're looking for volunteers to help create a Martian landscape on the 29th, and to dismantle it on the 3rd. Sounds like fun, or as much fun as moving rocks and sand can get anyway. A "To Mars Together" lecture with Carl Sagan, Alexei Leonov, and Igor Volk at NAS on the 28th ($20, less for PlanSoc members, call (818)793-5100) A release party and SETI fundraiser for the Voyager record, $50/ticket, $80/pair, at the Hard Rock Cafe on the 29th from 7PM to 9PM. Call the number above. PlanSoc also makes the following claim about the WSC's "International Exhibit" at the Washington Convention Center: "ADMITTANCE IS FREE to members carrying either a business card or a Planetary Society membership card. (Sorry, children will not be admitted to the Exhibit Hall.)" Will contain... dazzling innovation and state-of-the-art technology from 13 countries, blah blah blah... I attended last year's IAF conference in Montreal, learned a lot, and had a really good time. This year will be even bigger and fancier. I doubt they can beat Montreal's opening ceremonies, though: The Royal Canadian Mounted Police Jazz Orchestra, in full uniform, playing a Glenn Miller medeley at 8:30 on a Monday Morning. Really wakes you up... The conference fee is a huge bargain if you are a student and you have even a small interest in space... GO! You won't see anything like this on this continent for years to come. Hint: Bring a LARGE mailing tube. The exhibitions have some great giveaway posters, but it's awkward to carry them around.

Berkeley Newsgroups: misc.jobs.offered,ucb.jobs,sci.space,sci.astro Map the Unseen Universe The Extreme Ultraviolet Explorer (EUVE) Project is looking for talented and enthusiastic professionals to join our team in exploring and documenting stars and galaxies as they have never been seen before. EUVE is a NASA satellite that launched on June 7, 1992. Its four telescopes were designed and built at the Space Sciences Laboratory of the University of California, Berkeley. These high-tech instruments are scanning the sky in the first-ever study of the extreme ultraviolet, a band of the spectrum that cannot be seen from Earth. Discoveries await us in this previously unexplored region of space. Among the challenges of the EUVE mission is the development of software to interpret the data gathered by the satellite. This software will be used to study the entire sky, creating a map of the locations and intensities of stars and other astronomical sources emitting EUV radiation, and to convert photon events into meaningful data for in-depth scientific study. Scientific Programmer Box #08-106-11 The Center for EUV Astrophysics, University of California, Berkeley, seeks candidates for the position of Scientific Programmer (Programmer/Analyst II) with the EUVE Guest Observer Program. Responsibilities will involve working closely with a small team of scientists and programmers on the EUVE Project in the development and maintenance of software designed to handle data from the EUVE instrumentation. Using C, FORTRAN, and SPP languages on a network of Sun workstations under the Unix operating system, existing software will be modified. New software to solve complex science data analysis tasks will be developed, and most of the software will be supported in the IRAF environment. Each programmer is responsible for documentation of his/her code written. This documentation will be of a technical nature, but user guides and cookbooks will be composed, as well. Required: Background in a related field such as computer science, physics or math. Demonstrated scientific programming ability, with C programming experience. Experience with the UNIX operating system, image analysis and display algorithms. Familiarity with Sun workstations, X-windows, FORTRAN, and networking systems highly desirable.

A semiprofessional's recommendations (I've photographed 3 shuttle launches and sold both prints and pictures to magazines of launches as well as much other stuff): At 3 miles I got excellent results with a Canon A-1, a Canon 500 mm and a matched Canon 2X teleconverter. The effective f/stop was f/16. Films used were Ektachrome 64. On a bright sunny day I shot at both 1/500 second and 1/250 second. 1/500 gave really good image of the exhausts (both liquid and solid). 1/250 gave better over all balance. If I ever get a chance again, I'd likely opt for Ektar 125 (1 stop gain) and shoot at 1/500. That would overexpose the flames, but a good to excellent lab might well be able to bring them out in custom prints. Of course I used a solid tripod and _no_ exposure automation.
