STS-130 cupola question
Are they going to get the new cupola fully activated during the time the
Shuttle is at the ISS, so we can see views from inside of it as the Shuttle departs the station, or is that scheduled for after departure? Also, how exactly does it get from the cargo bay to its final position on the ISS? Is this done via the robotic arm on the ISS, the one on the Shuttle, or by EVA? Pat |

No guarantees, but the plan is before. Also, how exactly does it get from the cargo bay to its final position on the ISS? Is this done via the robotic arm on the ISS, the one on the Shuttle, or by EVA? Cupola is launched on one end of Node 3. Node 3 will be handed-off from Shuttle RMS to Station RMS and then berthed. Cupola will then be moved from its launch position to its final position by Station RMS. EVA will connect Node 3 to ISS coolant system, etc. Brian |

STS-130 cupola question
OK, now that your real question has been answered, I have another: How do the ISSonauts keep the inside surfaces of big windows optically clean? Absolute ethyl alcohol (which we used to use for optical surfaces at LPL and helped with Solstice Celebrations) and cotton cloths? Probably not, given alcohol's unfortunate propensity to combine energetically with oxygen. Windex and paper towels? Saliva and shirtsleeves? Or what? |

There was a presentation a few years ago on "ISS alcohol ban" and I read it thinking it was the drinking kind, but it was the cleaning kind. But for the life of me, I don't know what the "approved" glass cleaners on ISS are. |

I get the feeling that the astronauts are going to be discouraged from touching the window panes. Pat |

I found this: QC5020... http://www.andersonsanitary.com/msds.html Which links to this under link called: QC5020 Class Cleaner for Space Station http://www.andersonsanitary.com/MSDS...ss_Cleaner.pdf also an easier-to-read version about this on QC5020: http://www.midlab.com/midlab/images/...912-502000.pdf Appearance: Blue liquid with a faint alcohol odor and subtle floral scent. ? |

QC5020 contains a small amount of isopropyl alcohol
but is mostly water. ? |
