Therefore, I believe that NASA, the United States, and the project scientists and engineers, should all SWALLOW THEIR PRIDE and ask the Russians for help. The Russians have some equipment that could COMPLETE a MANNED comet rendezvous and sample return mission, ROUND TRIP, in a matter of only a couple of MONTHS! In spite of their economic and political problems, they are FAR AHEAD in space, militarily and scientifically. Most of the following information came from the late Dr. Peter David Beter, a well respected Washington, DC attorney, Doctor of Jurisprudence, and expert and consultant in international law, finance, and intelligence, who received most of his information from many associates in the CIA and other intelligence groups of other countries who disapproved of many of the things happening or being planned behind the scenes. [See especially the 2-7-80, 5-14-81, 5-21-81, 5-27- 82, and 10-14-82 back-issues of WISCONSIN REPORT newspaper, P.O. Box 45, Brookfield, WI 53005; and The Dr. Beter Audio- Letters (AL) #64, #79, and #53.] The Russians have spacecraft called "COSMOSPHERES", which were originally built and used for "Starwars" defense. They are spherical in shape, INvisible to radar beyond about 50 miles away, atomic-powered [possibly Migma fUsion], electro-gravitic (can hover against gravity), and equipped with "Psycho-energetic Range Finding" (PRF) which tunes-in to the actual atomic signature of an object or target. The 3rd-generation JUMBO Cosmospheres occupy more volume than the Hindenburg blimp, and are ELECTRO-MAGNETICALLY PROPELLED (can accelerate continuously and rapidly, and make it to Saturn in three WEEKS!). [Many of them are armed with charged-particle beam weapons, neutron beam weapons, and/or microwave brain-scrambling equipment!] I would not be surprised if the Russians have already COMPLETED a comet rendezvous and sample return mission and have data and samples to share. AIR BOOMS, 1977-78 I wish to add that the 1st-generation COSMOSPHERES were deployed beginning in the Fall of 1977. In late 1977 and early 1978, there was a strange rash of giant AIR BOOMS along the East Coast of the U.S and elsewhere. The AIR BOOMS were never satifactorily explained, by either the government or news media. They could NOT be positively identified with any particular SST or other aircraft, and indeed were much louder than aircraft sonic booms. The giant AIR BOOMS were actually caused by Russia COSMOSPHERES firing CHARGED-PARTICLE BEAMS down into the atmosphere in a DE-focused mode (spread out) for the purpose of announcing their presence to the WAR-MONGERS in the U.S. Pentagon. [AL #29.] The 3rd-generation JUMBO COSMOSPHERES were first deployed in April 1981, in parallel with the first U.S. Space Shuttle Mission. They significantly INTERFERED with that mission, in ways which were successfully COVERED-UP by NASA using techniques similar to those shown in the movie "Capricorn I". [AL #64.] CREDIBILITY of Dr. Beter I wish to give some additional information supporting Dr. Beter's credibility, and that of his informers. Dr. Beter predicted the bombing of the Marines in Beirut A FULL YEAR BEFORE IT HAPPENED. He warned that the U.S. Pentagon and the Israeli Mossad were CONSPIRING to DELIBERATELY ARRANGE IT in order to try to get Americans angry at the Arabs. (It was NO SURPRISE to me when it happened!) [AL #78, #79, and #80 (11-3-82).] Dr. Beter predicted the assassination of Anwar Saddat SIX DAYS BEFORE IT HAPPENED. [AL #68 (9-30-81) and #69.] Dr. Beter predicted what he called the "RETIREMENT" of Leonid Brezhnev ONE WEEK BEFORE Brezhnev "died". [Note that the word "retirement" was used for the TERMINATION OF REPLICANTS in the 1982 movie "Blade Runner".] He also predicted that Brezhnev would be quickly replaced with Andropov, which occurred ONLY THREE DAYS after the "death" of Brezhnev, to the SURPRISE of all government and media analysts. [AL #8O (11-3-82).] Dr. Beter was able to "predict" these events because he had been INFORMED about the PLANS to carry them out. [I KNOW that we are all supposed to LAUGH at the word "conspiracy". That is what the various government, military, political, media, banking, and corporate CONSPIRATORS have successfully PROGRAMMED most of us to do. ] THE DR. BETER AUDIO-LETTERS ALL 80 Dr. Beter Audio-Letters (about 50 KB each) and an Overview (about 75 KB) have been digitized by Jon Volkoff at "eidetics@cerf.net" and are available from him and from some FTP sites where he sent them. Jon Volkoff states: "I know of two ftp sites (there are a few "gopher" servers too) as follows: uglymouse.css.itd.umich.edu (141.211.182.53), under /pub/Politics/Beter.Audio.Letter ftp.uu.net (192.48.96.9), under /doc/political/umich-poli/Beter.Audio.Letter ." I especially recommend Audio-Letters #64, 74, 40, 53, 54, 55, 45, 46, 47, 48, 78, 79, and 80, and the Overview. ALL of these will fit on a SINGLE 3-1/2-inch disk formatted for 720 KB. Audio-Letter #64 is about the "STS-1 DISASTER/ /COVERUP". Audio-Letter #74 is about the "SECRET PURPOSE of the Falklands War", and includes IN-VISIBILITY Technology and a Russian NEUTRON BOMB. Audio-Letter #40 is about the "MILITARY PURPOSE of Jonestown Mass-MURDER". ELECTRO-MAGNETIC PROPULSION I indicated that the Russian 3rd-generation "JUMBO COSMOSPHERES" are ELECTRO-MAGNETICALLY PROPELLED. I heard of that concept long before 1981, in connection with UFO's and unorthodox inventors, but I never was able to find out how or why they work, or how they are constructed. I found a possible clue about why they might work on pages 112-113 of the book "BASIC PROPERTIES OF MATTER", by the late Physicist Dewey B. Larson, which describes part of Larson's comprehensive GENERAL UNIFIED Theory of the physical universe. I quote one paragraph: "As indicated in the preceding chapter, the development of the theory of the universe of motion arrives at a totally different concept of the nature of electrical resistance. The electrons, we find, are derived from the environment. It was brought out in Volume I [Larson's book "NOTHING BUT MOTION"] that there are physical processes in operation which produce electrons in substantial quantities, and that, although the motions that constitute these electrons are, in many cases, absorbed by atomic structures, the opportunities for utilizing this type of motion in such structures are limited. It follows that there is always a large excess of free electrons in the material sector [material half] of the universe, most of which are uncharged. In this uncharged state the electrons cannot move with respect to extension space, because they are inherently rotating units of space, and the relation of space to space is not motion. In open space, therefore, each uncharged electron remains permanently in the same location with respect to the natural reference system, in the manner of a photon. In the context of the stationary spatial reference system the uncharged electron, like the photon, is carried outward at the speed of light by the progression of the natural reference system. All material aggregates are thus exposed to a flux of electrons similar to the continual bombardment by photons of radiation. Meanwhile there are other processes, to be discussed later, whereby electrons are returned to the environment. The electron population of a material aggregate such as the earth therefore stabilizes at an equilibrium level." Note that in Larson's Theory, UNcharged electrons are also massLESS, and are basically photons of light of a particular frequency (above the "unit" frequency) spinning around one axis at a particular rate (below the "unit" rate). ("Unit velocity" is the speed of light, and there are vibrational and rotational equivalents to the speed of light, according to Larson's Theory.) [I might have the "above" and "below" labels mixed up.] Larson is saying that outer space is filled with mass- LESS UN-charged electrons flying around at the speed of light! If this is true, then the ELECTRO-MAGNETIC PROPULSION fields of the Russian JUMBO COSMOSPHERES might be interacting with these electrons, or other particles in space, perhaps GIVING them a charge (and mass) and shooting them toward the rear to achieve propulsion. (In Larson's Theory, an electrical charge is a rotational vibration of a particular frequency (above the "unit" frequency) superimposed on the rotation of the particle.) The paragraph quoted above might also give a clue to confused meteorologists about how lightning is generated in clouds. For more information, answers to your questions, etc., please consult by CITED SOURCES. UN-altered REPRODUCTION and DISSEMINATION of this IMPORTANT Information is ENCOURAGED. Robert E.

Newsgroups: sci.space A story appeard on the (Australian) ABC radio news last night that is of interest. It is also mentioned in "The Australian Financial Review" this morning (4/5/93), p14. (Don't say I don't give references!) Space Transportation Systems is the company that was the preferred bidder for the Cape York space port, with a prominant polititian (Ahern, ex-Premier of Queensland) at its head. There was a one-last-time, firm-and-this-time-we-mean-it deadline for STS to line up funding for CY that expired without a whisper in December. Last night there was an announcement by the Prime Minister of Papua New Guinea (PNG, an island nation to the north of Australia and east of Indonesia - basically half the huge blob just north of Cape York, the pointy bit on the east edge of Australia that was the preferred site for the space port.). STS has been given an in-principle go-ahead for the establishmnent of a commercial spaceport on an as-yet unchosen PNG equatorial island. The project was predicted to cost about $USD 920m. Talks with internation funding sources are continuing, and STS is "confident about their success." A feasability study (a $mil or so) is about to begin and could be completed by the end of 1993. This pretty much implies that Cape York is dead, and the report said as much. More details as they come to hand.

One technique is to put you in a chair that spins at about on rev/sec. ... At the sound of each beep, you must tip your head as far as you can, first towad the right shoulder, then toward the left. The coriolis effect of this movement causes the fluid in your semi-circular canals to swirl rapidly, first one way, then the opposite. My first sensation was extreme dizziness, but very quickly, a strange sensation manifested itself. With no visual frame of reference, with continuing head-tipping, it began to produce the sensation of swinging forward and back! ... This is a truly amazing effect, none the less wonderful for being (apparently) a simple manifestation of the coriolis force. With care, you can feel it (to a lesser degree than George experienced) on the centrifuge rides often seen at fairs and amusement parks. Often the instructions tell you not to turn your head during the ride. Ignore them. You will find that rotating your head along the same axis as the ride's, will produce normal sensations, but that rotating it about an axis perpendicular to the ride will cause strange sensations -- your inner ears register a head rotation about the third axis, perpendicular to your cervical proprioception! I first experienced this in the `Shuttle ride' centrifuge at the Huntsville Space Museum, in Alabama -- it's a very good ride, as they've carefully removed all visible non-rotating reference points, and the bearings are quite smooth. The only clue that you're rotating is the coriolis force. -- DON'T DRINK SOAP! DILUTE DILUTE!

Earth gravity anomalies (mountains) ARE important due to low orbits (LEO) of about 2 or 3% of Earth radius. 2. Earth oblateness causes even larger gravity anomalies, but these are symmetrical with respect to Earth's rotation, and hence "stationary" from satellite point of view (ignoring Earth's Sun orbit) OK, here's my 2 cents ... Earth's mass is not a pinpoint, but is distributed (unevenly) throughout a "sphere" with bumps (mountains) & broad hollows (oceans). Imagine an extreme case with 2 half earth masses joined by a stick, forming a dumbbell. If that rotated daily, a satellite would be dragged around (to some extent) with it, due to nonlinearity of distance relationship of gravity. Given the right conditions it could even be captured into geostationary orbit. Now Earth's bumps are infinitely smaller than that extreme case, but when all other forces are small enough, a satellite whose n-th oribt happened to keep coinciding with a good sized bump, would get a (very small) boost. Now as to where does the energy come from, IMHO it comes from Earth's angular momentum, & in principle Earth is slowed (infinitesimally). If that's rubbish, please shoot me down, my physics is rusty.
