  3. Re:"Civilian" Spacecraft? on Dragon Capsule Could Be 1st Private Craft To Dock With ISS · · Score: 3, Informative

    Surely NASA is a "civilian" space agency, and the shuttle therefore a civilian craft?

    No, numerous design decisions early on in the program were made strictly to appease the defense dept. Most of them revolved around the mission requirement of launching, grabbing a russian spy sat and placing it in the cargo bay, and landing on next orbit. This requires a ridiculous cross-range capability as the launching site rotates with the earth about 2000 miles east during an orbit. Also the DoD mandated some weird on orbit maneuvering capability which I don't remember (probably some classified anti-asat maneuverability, or maybe it was something to do with the RCS system being stable enough to stick a telescope in the cargo bay for military observational purposes?)

    There was also a long cross range capability for military purposes... If a civilian is worried about landing short, just aim at the center of the USA and you're all good. Insane as it sounds, if you want to land at a military base in Japan or Israel, and its a no-go for weather or whatever, you need crossrange to ... somewhere freaking far away. What, Korea or Australia as alternates for Japan, or maybe... diego garcia as an alternate for israel? Unlike F-16s etc we never sold any shuttles to Israel or even landed ours in Japan. But the DoD made us design the vehicle to possibly do it.

    The point wasn't to actually steal russian sats, which would be quite the diplomatic incident. The point was to scare them into a higher orbit out of SS range. Same sat higher up means lower resolution and less consumables means its got less lifetime and/or costs more. You only have to scare them once, during design phase, and their sats are crippled until the next generation. Presumably we wouldn't steal our own sats, and they were not going to make a clone of our SS (although turns out they did anyway) so in true cold war deterrence fashion, the end result of building the SS to DoD specs means the russians inherently end up with crappier spy sats than we do.

    Well, we never did a mission like that, never even flew a super long cross range landing, for most of the active flying SS program the USSR no longer existed, it got really popular to put a giant sat with giant optics and long lifetime in geosync instead of little ones in low orbit that deorbit relatively rapidly. So it was all kind of pointless.

    I think it's more like asking, "If these plants typically grow in 65-100 degree weather, why are we putting them in a greenhouse instead of outside where it's typically 65-100 degrees?" Plants in that region don't need more heat - They have plenty.

    I think you're confusing average temperature for the entire year, averaged across the entire state, with minimum winter temps in the north. Weird as it must sound to people who don't live there, my AZ cousin "often" had colder weather in northern AZ during the winter than I did in WI. Frost is very common and below 0 F is about as newsworthy as it is in WI. Something to do with moderating effect of large bodies of water, also higher altitude.

    Trust me, its pretty easy to freeze to death in the desert, either at night, or in the winter, or both. Idiots get killed all the time going out in the desert in tee shirts and shorts on a warm/hot day, then get stuck out there and freeze to death. Unlike the midwest, you need blankets in the car trunk, just in case, even if its 80 degrees at noon. I lived near the gulf coast and on a cloudy day the delta T from midnight to noon might have been 10 degrees... in the upper midwest its about 20 degrees... in the desert its often 60 degrees... Plants don't like that, you need a greenhouse in AZ a lot more than you need it in WI.

    Money might be a good start. Even in schools where this $5 Billion reaches, they still expect to pay teachers poverty wages.

    The social contract was you pay them poverty wages at age 22 right outta college then every year they get inflation adjusted PLUS 5% more. So rather suddenly they find themselves middle class, and by the time the gray hair arrives, they're doing pretty darn well.

    This is completely different from the private industry model, where you hire at 22, pay pretty good wages, fire at 35 due to ageism, and after that they ... I donno what we/they do.

    The problem is we're having a second great depression, and the hiring has stopped, and the laying off has begun. So they no longer hire at 22, they hire at, say, 35. Not so easy to get 40 years in if you're not hired for your real job until 35. So the social contract has gone from "you'll start out young and poor, and retire rich" to "you'll work as a day care worker and/or bartender until middle aged, then be dirt poor, and maybe with luck retire as almost middle class".

    The other problem is the union busting government wants to change the social contract to the private industry model, yet not modify salaries to match. So they wanna hire them at 22, tell them they'll get 5% wages until they retire, then fire them at 35 once they get too expensive relative to a new grad who will hear the same old lie about starting out in poverty but you'll get 5% raises until you retire (forgetting to mention they'll be forcibly retired at 35 now instead of 65)

There's already a lost generation where virtually all teachers between 22 and 40-something have been laid off per union seniority rules, and all the boomers are starting to retire, so rather suddenly the average age, salary, and competence level of school teachers is about to collapse once the last boomer leaves the building and they hire all fresh grads.

    My understanding is the special ed teachers are in high demand and as such demand high salaries.

    Poor districts can't afford them. So they don't have them. Coincidentally, they have not identified their LD students as LD; to do so would open them to firing for providing inadequate services. On the other hand, if they happen to not have LD kids, then they are not in trouble for not providing services to the kids that don't exist. In some areas, on a percentage basis, there are more LD kids in the well fed rich, well taken care of districts, than in the poor crack and alcohol infested once a day and only junk food meals districts, which is the reverse of what you'd expect. They'll try to tell you it's because in the poor areas, the dumber kids drop out of high school, until you point out this applies to 1st graders. Oddly enough this results in much lower average achievement in poor districts vs rich districts amongst children not identified as LD. I have heard about this systemically, and also experienced it first hand... in a sorta-rich area, where they brag about the schools, any below median kid is LD and receives special services. In the poor areas, they just mainstream the kids and blame the parents, society, etc for lack of achievement.

    Aside from straight up special ed classroom teachers, this also applies to teachers aides, speech and language development teachers, specialists in reading and math, specially-designed-phy-ed, etc. My kids "rich-ish" school has a dedicated speech teacher and a librarian with a reading specialization degree... the poor kids school, eh, not so much. Maybe one per district instead of one per school.

    The signalling is not completely a waste, in that rich districts really do provide better service for the kids at the low end. However, the signalling fails in that a truly average human kid would not do as poorly in a poor district as the numbers imply. Yes, they would do considerably worse, but not as bad as expected. Also explains why forced integration didn't really help the school test scores very much, because the poor school still can't afford to provide services to failing rich kids.
