If you assume the existance of a working SSTO like DC, on billion $$ would be enough to put about a quarter million pounds of stuff on the moon. If some of that mass went to send equipment to make LOX for the transfer vehicle, you could send a lot more. Either way, its a lot more than needed.  This prize isn't big enough to warrent developing a SSTO, but it is enough to do it if the vehicle exists.    Allen

It is not even April 1 anymore.  If this is true, I think it's a great idea.  Learning how to build to build structures in space in an essential step towards space development, and given that Freedom appears to be shrinking towards the vanishing point, I question whether NASA's space station is going to provide much, if any, knowledge in this area. (Especially if a design such as Faget's wingless orbiter is chosen...) If such a project also monitors ozone depletion and demonstrates creative use of (partial) private sector funding in the process -- so much the better.  >Is NASA really supporting this junk?

Forwarded from the Mars Observer Project                         MARS OBSERVER STATUS REPORT                              April 30, 1993                               11:30 AM PDT  DSS-65 (Madrid 34 meter antenna) did not acquire the expected Mars Observer Spacecraft signal at the scheduled beginning of track yesterday morning (4/29) at approximately 6:00 AM.  Indications were that the spacecraft had entered a Fault Protection mode sometime between that time and receipt of normal telemetry at the end of the previous station pass (DSS-15 - Goldstone 34 meter antenna) at approximately 8:00 PM the evening before.  Entry into Contingency Mode was verified when signal was reacquired and telemetry indicated that the spacecraft was sun coning.  After subsystem engineers reported all systems performing nominally, fault protection telemetry modes were reconfigured and memory readouts of command system Audit Queue and AACS (Attitude and Articulation Control Subsystem) Starex performed.  These readouts verified that Contingency Mode entry occurred shortly after 1:30 AM yesterday, 4/29/93.  Preliminary indications are that a Sun Ephemeris Check failure triggered fault protection.  However, the Flight Team will be determining the precise cause over the next few days.  As of last evening, the spacecraft had been commanded back to Inertial Reference and was stable in that mode.  The Flight Team is planning to command the spacecraft back to Array Normal Spin state today.

While I'm sure Sagan considers it sacrilegious, that wouldn't be because of his doubtfull credibility as an astronomer. Modern,  ground-based, visible light astronomy (what these proposed orbiting billboards would upset) is already a dying field: The opacity and distortions caused by the atmosphere itself have driven most of the field to use radio, far infrared or space-based telescopes. In any case, a bright point of light passing through the field doesn't ruin observations. If that were the case, the thousands of existing satellites would have already done so (satelliets might not seem so bright to the eyes, but as far as astronomy is concerned, they are extremely bright.)

I hope others chime in with suggestions on specific technologies which could be applied towards the maintenance of an Earth like atmosphere on a long-duration spacecraft.  Tim et al: I think we should try looking at atmosphere first. This seems to be the single most fundamental issue in keeping anyone alive. We're all taught that when supporting a patient you look for maintaining airway. So, in keeping with my trauma training (and keeping my emergency medicine professor happy), I suggest that we look at the issues surrounding a regenerable atmospheric circuit.  Howz that Tim?

Beyond that, I have no other info.  The sightings were apparently spurious.  There is no planet inside of the orbit of Mercury.  The idea of Vulcan came from the differences between Mercury's observed perihelion precession and the value it should have had according to Newtonian physics.  Leverrier made an extensive set of observations and calculations during the mid 19th century, and Simon Newcombe later improved on the observations and re-calculated using Leverrier's system of equations.  Now Leverrier was one of the co-discoverers of Neptune and since he had predicted its existence based on anomalies in the orbit of Uranus his inclination was to believe the same sort of thing was afoot with Mercury.  But alas, 'twere not so.  Mercury's perihelion precesses at the rate it does because the space where it resides near the sun is significantly curved due to the sun's mass.  This explanation had to wait until 1915 and Albert Einstein's synthesis of his earlier theory of the electrodynamics of moving bodies (commonly called Special Relativity) with Reimanian  geometry.  The result was the General Theory of Relativity, and one of it's most noteworthy strengths is that it accounts for the precession of Mercury's perihelion almost exactly.  (Exactly if you use Newcomb's numbers rather than Leverrier's.)  Of course not everybody believes Einstein, and that's fine.  But subsequent efforts to find any planets closer to the sun than Mercury using radar have been fruitless.  -Bill Gawne   "Forgive him, he is a barbarian, who thinks the customs of his tribe   are the laws of the universe."                       - G.

We are interested in constructing a reentry vehicle to be deployed from a tether attached to an orbiting platform.  This will be a follow on to our succesful deployment of a 20 kilometer tether on the March 29 flight of SEDS (Small Expendable Deployment System), which released an instrumented payload that reentered the earth's atmosphere and burned up over the west coast of Mexico.  This time we want to make a payload that can be recovered. We want to build it from "off the shelf" technology so as to do this as quickly and inexpensively as possible.  We want to be able to track the payload after it has deployed its parachute.  An idea we have is to put the same kind of radio beacon on it that is used with SARSATs (Search and Rescue Satellites).  It would turn on with the opening of the parachute and aid in tracking.  These beacons are known in the marine industry as EPIRBs (Emergency Position Indicating Radio Beacon).  They are rugged (they have to be to survive a ship wreck!) and cheap.  We have several questions:  1.  What is the world authority regulating the use of SARSAT beacons.  Are there multiple authorites, i.e. military and civilian?  2.  What are the regulations regarding the use of SARSAT signals.  Can they be used for one of a kind situations with a long lead time of warning the relevant authorities, or are they strictly reserved for life threatening emergencies?  3.  What is the coverage of SARSATS?  Are they in LEO with only intermittant coverage of a fixed position on the earth, or are they in geosynchronous orbit?  4.  Is there an industry organization governing the use and manufacture of these transponders?

I had spacefood sticks just about every morning for breakfast in first and second grade (69-70, 70-71).  They came in Chocolate, strawberry, and peanut butter and were cylinders about 10cm long and 1cm in diameter wrapped in yellow space foil (well, it seemed like space foil at the time).    The taste is hard to describe, although I remember it fondly.  It was most certainly more "candy" than say a modern "Power Bar."  Sort of a toffee injected with vitamins.  The chocolate Power Bar is a rough approximation of the taste.  Strawberry sucked.  Man, these were my "60's."

There has been something bothering me while watching NASA Select for a while.  Well, I should'nt say bothering, maybe wondering would be better.  When they are going to launch they say (sorry but I forget exactly who is saying what, OTC to PLT I think) "Clear caution & warning memory.  Verify no unexpected errors. ...".  I am wondering what an "expected error" might be.  Sorry if this is a really dumb question, but inquiring minds just gotta know............

This sounds like another of Ali AbuTaha's 57 different "real causes" of the Challenger accident.  As far as I know, there has never been the slightest shred of evidence for a "harmonic resonance" having occurred.  The windshear-induced maneuvering probably *did* contribute to opening up the leak path in the SRB joint again -- it seems to have sealed itself after the puffs of smoke during liftoff -- but the existing explanation of this and related events seems to account for the evidence adequately.

With the continuin talk about the "End of the Space Age" and complaints  by government over the large cost, why not try something I read about  that might just work.  Announce that a reward of $1 billion would go to the first corporation  who successfully keeps at least 1 person alive on the moon for a year.  Then you'd see some of the inexpensive but not popular technologies begin  to be developed. THere'd be a different kind of space race then!
