The Magellan spacecraft continues to operate normally, gathering gravity data in its fourth 243-day cycle of Venus. All starcals (star calibrations) over the weekend were successful. There was a TWTA (Traveling Wave Tube Amplifier) spurious shut-off earlier this morning, which was corrected automatically. 2. There was no commanding of the spacecraft since Friday, and none is planned for today. Tomorrow the high rate gyro biases will be uplinked in the preparation for the high rate gyro calibration test starting Wednesday. 3. Magellan has operated using low rate gyro biases through most of the mission to date, so it has not been necessary to calibrate the gyros in high rate mode. But the aerobraking experiment which will start in late May has a moderate probability of pushing the attitude control into the range where the high rate mode is needed. 4. The 24th Lunar and Planetary Science Conference in Houston was attended by several Magellan scientists who presented technical papers. The Magellan exhibit was of considerable interest to the conference participants. 5. A memorial session on the Geology of Venus was held on Monday in tribute to Valery Leonidovich Barsukov, the late director of the V. I. Vernadsky Institute in Moscow. The session was chaired by J. W. Head and R. S. Saunders. Academician Basurkov was very active in promoting international cooperation in planetary exploration and made possible the sharing of Russian data on Venus exploration. 6. Magellan has completed 7042 orbits of Venus since August 10, 1990. Magellan is 64 days from the end of Cycle-4. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | Don't ever take a fence /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | down until you know the |_____|/ |_|/ |_____|/ | reason it was put up. ------------------------------ Date: 22 Mar 1993 22:28:39 GMT From: Doug Mohney Subject: plans, and absence thereof Newsgroups: sci.space,talk.politics.space In article , szabo@techbook.com (Nick Szabo) writes: >sysmgr@king.eng.umd.edu (Doug Mohney) writes: >>I wasn't aware that your one penny of every dollar of tax money was >> bigger than the one penny of every tax dollar Mr. Wingo pays. > >This is a truly stupid comment.

We seem > to be looking for the existence of the wavepacket. When you think about what kinds of things would emit gravitational waves, it's important to realize that gravitational waves are supposed to be quadrupole radiation; in other words, the kinds of things that ought to emit big gravitational waves are things with a mass distribution whose quadrupole moment changes hugely and rapidly. A pair of massive objects has a big quadrupole moment*, so you'd expect to see gravitational waves from things like binary pulsars where you have two really massive objects orbiting each other at an enormous speed, or collisions between black holes, or some such thing. * It's not a dipole! I've had an extraordinarily difficult time convincing people of this in the past. Note that the two objects have masses of the SAME sign, unlike, say, the charge distribution in a hydrogen atom. So the mass distribution is positive at one end, zero in the middle, and positive at the other end#, which (to low order) is a monopole plus quadrupole term. Of course, by putting the origin somewhere else you can give it a dipole moment, but what oscillates in a binary pulsar is the quadrupole moment. If an object just moves in one direction, what's changing is the dipole moment, and that won't make gravitational waves in general. # Would this be anti-Elkian?

U >Dennis, University of Alabama in Huntsville Let me get this straight - the SEDS tether experiment was mostly done IN HOUSE, with the exception of the tether. I presume that what you mean by the "tether" would also include the reeling mechanism, and the sensors to determine whether the tether is being unreeled correctly. Since the mission will use the US Air Force Delta second stage for telemetry, power and attitude control, that means that NASA's role in all of this is largely to pay the contractor to put the tether together, something that NASA couldn't do correctly itself in its $100 million Tethered Satellite System. ___ WinQwk 2.0b#0 --- Maximus 2.01wb ------------------------------ Date: 22 Mar 93 13:25:58 From: Steinn Sigurdsson Subject: SR-71 Maiden Science Flight Newsgroups: sci.space In article shafer@rigel.dfrf.nasa.gov (Mary Shafer) writes: On 21 Mar 1993 12:30:03 -0500, prb@access.digex.com (Pat) said: Pat> Has anyone considered which is more fun to ride along on while Pat> running science gear?

Gee Stein. You must have graduated from the nick Szabo school of debate. I never said that progress should stop, but How come Nobody uses it? My local power utility is paying me to replace all Pat, NASAs primary purpose, as I understand it, is to do the leading edge innovation, not to wait for someone else to do it. As I recall their primary purpose is to find out how best to get objects and people into orbit, secondarily to put such objects and people up there as the US government wants them to and thirdly to tell others (in the US) how to. ... Space engineering should develope and fund those areas it has to, not serve as a pet slush fund for every pet boondoggle that comes ou;of someones ear. Who funds Closed and semi-closed life support? NASA, Why? because they need it. IF the Air FOrce were to, that would be a boondoggle. Gee, I suppose the Navy isn't allowed to either. Stein, you get so fascinated with someting being new, you forget the utility value of money and the risk reduction. The DOE national labs should be testing High Frequency power, NASA should only leap on this when MASS becomes a crisis, and fat as FRED is, it wasn't necessary. NASA should research all areas that appear to be relevant to finding the _best_ way of getting to and operating in space. If the Labs or other agencies had done work on 20kHz AC power distribution then NASA should look at it, if not, and they have reasonable cause to think it might be of use then NASA should have the leeway to investigate it. Same with materials, propulsion technologies, battery technology and even food processing. ... |Look, NASA and others will hopefully over the next few decades |put a lot of power consuming items into orbit and chances are |we'll want to transmit most of the energy by electric currents. NASA had very few plans for SSF beyond it's 25 year life. SSF was planned out as a closed ended plan. Any ideas beyond that are in your Imagination. Down here, METRO is a closed end plan. NASA has a lot of plans beyond SSF, none are funded and all are speculation until the US government sets a plan. Hell, currently NASA technically doesn't have a plan for SSF - they are waiting for another government approval. Also, most of the packages flying will be small systems. I imagine they will do what every other package does. live on DC, with a 400 HZ AC system. I think galileo does that. They use what is available, no one package can justify developing a new system unless the existing systems won't do at all - that does not mean the current system is optimal. Oh, and it is not a good idea to always wait until you _need_ to deploy a new system before doing any development on it. |Now, maybe the current systems are optimal for this, maybe it |would be better ab initio but with current power electronics to |have higher frequency AC - _but_ if you think in the long run |a new technology will be an improvement then the time to adapt it |is when you start putting big power hungry semi-permanent structures |into place. For space, that is now. No stein. THe time to place new systems is after you have developed the technology and worked down the risk factors and understood the system implications under all circumstances. You just don't get it, you're never going to have the technology and low risk factors and you certainly won't understand the implications because no one ever deployed it because they have accountants looking over their shoulders who think Harvard business school depreciation schedules are natural law. Here is a simple case. Composite materials are far stronger and lighter then metals. In fact for large structures they are often cheaper, because they need not be Forged in giant presses or machined on giant lathes, yert what is the pressure vessel design for Fred, Aluminum? WHY? Because aluminum is better understood in the Vacuum environment. Gee Stein, why aren't you bellowing for an all composite station? Ab inito, if htey weren't doing this, why then no-one would....... By your argument the composites would never have been developed because aluminium would always have been sufficient - so much for the DC series then. Of course the development costs on the DC composites have already been sunk by DoD and NASA which get derided for wasting money while MD is applauded for applying this new yet well understood technology... | >When you're about to put up the first major piece | >of infrastructure in space, one that might in principle be | >expanded, it becomes sensible to consider the possibility of | >whether a new standard for such things as power systems makes | >sense in the long run. Funny you mention standards. When I suggested a metric standard, you moaned about english being fine, and who needs stnadards anyway. I have never in my life advocated anyone using english or imperial measures for any reason. I do think NASA should have gone metric, the switch over would have been expensive but would have lead to lower long term costs. | You mean, the way most things are built upon previous knowledge base? | Gee stein, you seem real positive over this technology, | why don't you go and build some lab equipment that pulls this | as prime power. |The point is not the 20kHz in particular, the point is that |_now_ is a good time to look into whether to make these kind of |changes - I don't know if the 20kHz is worth it, and I suspect that |the contemptuous dismissal of its potentials by you and other is |posturing bullshit fuelled by hindsight. It's not posturing bullshit, it's contemptous dismissal of an idea that is plainly ridiculous and a absolute waste of my tax dollars. ^^^^^^^^^^^^^^^^^^^^ In other words you only want research into systems that you know will work ahead of time... |This is the whole problem your way of "accounting" produces. |What if over the next 150 years using 20kHz power were to save |2 trillion dollars? But, we'll never know, because at any one time |it was cheaper for that one project to stick with the old stuff. Sorry, Stein, nobody accounts for anything with more then a 25 year lifespan. If you need a 100 year payout, you are looking at technological obsolesence. Some people do. Some technological development has lead times far longer then 25 years - of course in an accountants world those technologies don't exist. All systems have to be based upon the expected working life, and technological obsolesence is a major factor. look at how many computer technologies have died, in 10 years. And by the way, 2 trillion dollars over 150 years is petty change, we are talking about 15 billion dollars/year, and if you place any Gee, that's just about NASA's current budget. Petty change indeed... sort of interest rate on the money, you are talking only 3-4 billion. Petty change in DC. Stein, you should study a little accounting, it would help you out. 3-4 billion is twice SSFs annual construction budget. You have real funny idea of what matters. |You just don't get it, it's NASAs purpose to look into these |alternatives without having to worry about whether the immediate |benefit to that particular project provides a good return in the |next N quarters. I'm really glad people like you weren't in charge |of the Royal Society of London 150 years ago. Gee stein, you dont get it. Nasa doesn't look into new alternatives without worrying about immediate return for projects. Every program manager works They should. hard at risk reduction on his particular program because if the program goes south, he's out of a job. A major complaint I and Henry have about NASA is they don't have an ongoing engineering research and testing program. Well, how could they, they have to show return on all their programs and god help them if one should actually not pan out, they'd get fried for wasting your tax dollars on such obviously ridicilous ideas... It is the purpose of every project to succeed. and gratuitous slurs about the Royal society are un-needed. ANd if you knew more about history then about stars, you'd know the brits were very big on tying innovation to existing technologies. Oh, really, how long did it take for them to get a return on electromagnetic induction? Did they manage to scrape in under the 25 year deadline. Of course if the silly sods had just invested the salary they paid Faraday in an interest bearing account they'd be rolling in it now. ... | No doubt, smaller then that for 20KHz.

Gee stein, I hate to say this, it must hurt your perfect little world, but Boeing's commercial market is probably 2 orders of magnitude larger then NASA. NASA spends about 1-2 billion/year on hardware, Hot damn, Boeing's turnover is $trillion? I never appreciated they made up 15% of the US economy... Boeing probably sells 15 Billion / year on aircraft. Which, funnily enough is about the size of NASAs budget NASA buys about 10-12 rockets/ year. Boeing sells 2-300 aircraft per year. Believe me, THese guys have their own markets. Some things they glom off NASA and AF programs, but this one they don't need to. And besides, stein, if 20 KHz was so hot, why aren't any other nasa programs pursuing it?
