We noted that the Rover's camara panned up to follow the moduale's acsent and my wife said "now it is all alone". Then the narrator went on to say the lunar mod was released before burn back to earth. What happened to them? Did these moduales crash to the moon or drift out to space or fall into some kind of lunar orbit? Does anybody know if any of the experiments or hardware still work or how long some of the stuff did work? When was the last time one of those camaras were turned on? Do the siesmonitors still send back data? The Voyager space craft have lasted so long It seemed like there was a chance many of these things may have worked well into the Seventies if not longer even though they came from an earlier technology. We were pretty interested in knowing if it was planned to explore these sites in the future to see the effects of long term exposure. I can't help fantasing about someone someday charging the old Rover batteries to see if it will work again like someone now finding an old piece of equitment in a long forgetten barn. Anybody have any information for me?

Yes Jack, there is. In Huntsville Alabama, there is a K-6 school named the "Challenger School". It was so well designed and spacious, that after the 1989 tornado disaster in Huntsville (over 30 killed and Millions in damage) another K-6 school that lost it's entire building to the tornados, was "absorbed" (resistance is futile :) ) into Challenger School and kept totally seperate in its operation from the "existing" Challenger student body. Also, Huntsville being a space kind of place, the high school that is my "alma mater" is named after Gus Grissom with two other schools in Huntsville named after Chaffee and White.

I've received a couple of inquires about how the repressurization, and here's how it is done. Magellan carries a small tank of helium at about 3000 psi which is connected to the main tank. The main tank contains hydrazine and a bladder wall is used to separate the hydrazine from the helium. The helium used as a pressurant. When the pyros are blown on the valve connecting the helium to the main tank, this allows the helium to flow into the bladder in the main tank, raising the pressure there from about 300 psi to 450 psi. The higher pressure in the main tank allows more pressure to be put through the thrusters, as needed. This was all designed in anticipation of aerobraking maneuvers, which require a large number of vigorous thruster firings.

Yes, it was called "Shuttle-C" and it was fully supported and then killed by the same man, Capitol Hill Man...Bill Nelson. Ironically, Nelson used his powerful ties to NASA funding to wangle a space shuttle flight in the early eighties...I believe he is also being looked at to replace Goldin as NASA Chief. BTW, Shuttle-C would have been a wingless form of the Orbitor (cabinleess too) that would essentially have been one big cargo bay, utilizing up to three SSME's on their "last legs" as well as the normal or standard SRB and ET stack that the current configuration for STS has. The program outline called for leaving the "C" in orbit after payload deployment.

How does the Japanese government developing a mini-shuttle to service their module have anything in the world to do with what the market charges for services?

The Japanese don't just want backup. From what I've heard they are rather worried that shuttle won't be able to carry all the stuff they want for their materials proccessing experiments. They'd like to be able to produce a high volume although their expectations may have changed when the available power dropped. By the way Allen, I should point out that paper airplanes and vaporware don't have operational costs. If and when HOPE flies you can decided that it's cheaper than shuttle but the way things are looking now I wouldn't advise you to take that for granted. >I would like to see an unmanned alternative to the Shuttle for primary >logistics support; don't suppose anyone knows if this is in the works >or not? HOPE would be unmanned. ESA is also interested in an Ariane 5 launched resupply vehicle.
