We had this topic not so long ago, but maybe it was on sci.astro, where I think it belongs. That criterion is not so reasonable -- it depends on the distance between the bodies. Suppose Charon was at 1/3 its actual distance from Pluto -- then the barycenter would be inside Pluto. (Assuming the other postings in this thread are right.) Does it make sense to change the designation just because you changed the distance? I don't see that this is something we need an exact definition for, but if you really want one, then I think you should base it on the ratio of the masses. -- Mark Brader, Toronto "...

The Magellan spacecraft is operating normally, as it approaches its 7000th orbit of Venus next Tuesday. (For those of you who have access to orbit numbers and are confused by the difference between the current orbit number and this count, remember that the first orbit after Venus Orbit insertion was 100 and an adjustment during the in-orbit-check-out added another 11.) 2. The swath one starcals (star calibrations) continue to produce attitude updates which average 0.1 degree. This is higher than the normal setting of the innovation bound. The swath two starcals (which scan the same two stars in the opposite direction) result in updates which average only 0.01 degree. The limit is presently widened to 0.2 deg. 3. Yesterday spacecraft controllers uplinked the G3071 command sequence which will control the spacecraft for the next four weeks. It went active at 9:33 AM PST today and is very similar to the last several command sequences. 4. The spacecraft performs a reaction wheel desaturation on every orbit, a starcal on every other orbit. The High Gain Antenna is kept pointed toward Earth (except during the starcal) in order to acquire gravity data, especially around periapsis. Engineering telemetry is being received at 1200 bps. 5. The Magellan Project continues to implement the plan with the MESUR (Mars Enviromental Survey) Pre-project to collocate 50 MESUR members on the second floor of Bldg. 230, with minimal impact to MGN preparations for TEX (Transition Experiment) and LMGT (Lean Mean Gravity Team) . Several MGN team members have moved this week, and the remaining moves will be complete by March 31st. 6. Magellan has completed 6966 orbits of Venus since August 10, 1990. Magellan is 74 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: 15 Mar 93 17:30:29 GMT From: kebarnes@msuvx2.memst.edu Subject: Mars - Unusual Surface Features lat/long?

Also, if someone could confirm that the "Face" rock in Cydonia is at 40.89 N 9.52 W. (I believe the source for this was "Unusual Martian Surface Features" by DiPetro & Molenar (sp?)) There's also supposed to be a feature termed the 'White Rock' that's located inside a 58 mi. diameter crater near the equator. This albedo feature is supposed to be approximately 8.5 x 11 miles.

I'm talking operations here. I'm not a NASA person. I've never worked for the government. However, I have never worked for a company that, in my opinion, allowed me the freedom for my best expression. There were always restrictions that I felt that I could have done better without. I'm talking about operations, R&D, support, etc. Am I angry about that? Sometimes. That's the reason for few of my job changes. In other cases I knew that there would be restrictions because my boss and my boss's boss and so on up decided that the company, division, group, activity, department, section, and/or me should go in one direction while I believed, based on my experience, that we should go in a different direction. I have worked in atmospheres of *relative* freedom where I could do most anything I wanted, but there were still limits. I have also worked in environments of great restraint where I was told to do a certain job or leave. Sometimes I've done poorly in a free environment and sometimes I've done well under immense pressure. What's my point? My point is that you haven't got a point with what you said. It is not demonstrable that the job NASA does could be done better by private industry. Some of the tasks involved could be effectively privatized but there are other jobs which really aren't and shouldn't be profit motive driven. Those are poor candidates for privatization. --- Mark Perew Mark.Perew@ofa123.fidonet.org --- Squish v1.00 ------------------------------ Date: 16 Mar 1993 06:56 UT From: Ron Baalke Subject: Planet X Newsgroups: sci.space In article , henry@zoo.toronto.edu (Henry Spencer) writes... >The problem is that the best evaluation of the orbits of Uranus and Neptune, >based on the best observations (the 20th-century ones), says that there is >*no* unexplained error in their positions. It is interesting to note that before Neptune was discovered, and perturbations were noted in Uranus' orbit, some people discounted the perturbations as being inaccuracies in the observations. This strikes me as being very similar to the situation today, in that the pre-1910 observations are being discounted as being unreliable. >Any proposal for a tenth planet also has to explain some other major >bits of negative evidence. There is no unexplained perturbation in the >trajectories of Pioneers 10 and 11 and the Voyagers, and their positions >can be measured far more accurately than those of the planets. John Anderson at JPL who studied the Pioneer trajectories, is convinced that there is a 10th planet, but that it is in a highly elliptical orbit. If so, then the planet may be in an orbit with a period of 700 to 1000 years, and its gravitational effect won't be detected again until around the year 2600. >Tombaugh's >sky search, which was good enough to find an insignificant little speck >like Pluto, should have spotted any major planet unless it was a long >way out or far away from the ecliptic. Tombaugh discovered Pluto by accident. He was looking for a much larger planet to explain pertubations in the orbits of Uranus and Netune. Unfortunately, he never found it. >IRAS didn't find anything either, >looking in wavelengths where a gas giant ought to be much more prominent >than in visible light. IRAS recorded 600,000 objects. No one has done a thorough check of the *entire* IRAS database for a 10th planet.

George Null of JPL thinks he knows. They used HST to measure the barycentric wobble, and came up with a mass ratio of about 12 to 1, indicating a lower density for Charon than Pluto. The barycenter is still exterior to Pluto, however. By the way, those +/- figures for the Pluto and Charon radii don't include the uncertainty in the yardstick for the system, namely the 19,640 +/- 320. Include that uncertainty, and both radii come up with +/- about 20 km. HST has provided a better value for the yardstick, but I'd like to wait and see how well it agrees with some additional ground-based results we've been working on. ------------------------------ End of Space Digest Volume 16 : Issue 320 ------------------------------
