Not that I'd actually expect any reply from ISS but, it would be
interesting and highly informative as to hear something/anything directly from the crew of ISS, or even from those of prior missions or from the soon to be ISS crew, as to contemplate exactly what these folks think of spending a little R&R (rad and rem) time outside of the Van Allen zone of death. ISS is supposedly far better shielded than any portion of those Apollo missions, in some directions ISS must offer 100 fold more combined mass for dealing with the likes of cosmic and solar radiation. Thus according to the Apollo-13 mission that merely orbited the moon and returned as directly as possible to Earth, their reported average TBI dosage wasn't all that bad (240 mr or 40 mr/day), as compared to Apollo-11 which oddly spent two extra days and supposedly 36 hours worth of that walking essentially TBI naked on the highly reactive lunar surface amounted to merely 180 mr (22.5 mr/day). Thus a non lunar landing and less time in space travel was nearly twice as radiated as per actually walking upon the moon (somehow the physics of all that doesn't compute, but then a good deal of the lunar surface as recorded by Apollo doesn't add up either). With the added shielding afforded by ISS, and the fact that ISS shouldn't get much closer than 60,000 km from the lunar surface, I'm thinking worse case daily interior dosage could be close to 50 mr/day. But if those Apollo readings were in correct by a factor of ten fold, that's still only pushing the ISS interior to 0.5 rem/day, whereas I believe ISS crew tolerance per mission of 50 rem is thereby good for 100 days worth of being fully solar and moonshine illuminated. Actually, the secondary IR energy being radiated off the moon could impose a greater threat than X-Ray dosage, not to mention running into whatever at 30+km/s isn't going to be all that pleasant. Of course, if the combined dosage of lunar secondary, cosmic and solar influx is honestly capable of being a hundred fold worse off than during those Apollo missions, in which case the ISS will likely remain as a robotic platform until operating within total darkness or by earthshine, or until a few tonnes worth of shielding and thermal management can be augmented to the critical crew area of ISS. Too bad we still don't have interactive surface instruments telling us squat. Perhaps including robust sleeping coffins of sufficient mass will become good enough, as otherwise operating within total darkness or by earthshine is where the space environment shouldn't be 10% of being fully illuminated plus receiving the full dosage of those secondary rads of hard-X-Rays off the moon. There must be quite a measurable difference, though oddly there has been no such comparable data from anything Apollo or just about any other mission that'll publicly share the knowledge of exactly what the moon has to offer, or otherwise charted of the radiation environment as traveling between us and the moon within darkness, comparing that to being fully illuminated. It's almost as though all such reflected thermal energy and secondary radiation environment data has been intentionally excluded, at least I haven't been smart enough as to locate where such information is specifically recorded, thus it must be another one of those deep dark secrets. I have a few other related topics to share, some of which are not specifically about our moon, though in more than a few ways everything about future space exploration and just plain old space travel itself is directly related to at least utilizing our moon as a rather necessary gravitational booster shot, of passing as close to the moon as possible; The Moon, LSE-CM/ISS, Venus and beyond, with He3 to burn Lunar/Moon Space Elevator, plus another ISS within the CM Terraforming the moon, before doing Mars or Venus Life on Venus is absolute hell, but doable Ice Ages directly regulated by Sirius Space Policy Sucks, while there's Life on Venus Regards, Brad Guth / GASA-IEIS http://guthvenus.tripod.com/gv-topics.htm -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
