    To me a 'space station', as opposed to a Manned Orbiting Laboratory,
    should have most or all of the following:
    1. crew turnover/rotation/replacement: skylab- yes
    2. Crew overlap (either overlap between primary crews, or occasional
    visitor crew): no, though there was provision for it
    3. resupply (other than what each primary crew brings with them): no
    4. expandable/reconfigureable in orbit: no
    5. interaction with other orbiting craft (other than COLAs!): no
    6. At least one crewmember whose duties are >~25% non technical,
    ie administrative, rather than everything being micro- or nanomanaged
    from the ground: no
    Are these out of 50s sf? Of course. But there is also a lot of Antarctic
    analogy in there. But then if 'space station' wasn't already such an
    emotionally loaded term it wouldn't be such a political mess. 
    MIR and ISS? space stations.
    Skylab has a 'yes', a 'well, it could have', and 4 'no'. not a space
    station, at least not for me.
    Salyut 7? maybe.
    So I get either beta or gamma for ISS.
    OB sat viewing:
    During the recent period when both MIR and ISS were making visible
    evening passes at mid northern latitudes I ran off some predictions
    for my folks in Tulsa. I had hyped the occasion for the 'final view'
    of MIR. I was quite put out on noticing that MIR was passing through
    NN=~16. The ground track and pass times were repeating on a daily
    basis-- and Tulsa was between two orbital tracks. Not a decent pass
    for MIR the whole time! At least ISS performed ok.
