• Latest debris analysis green.  The crew of the helo that helped us yesterday just came by the RCC - we shook hands and gave them Antares FLight One patches.

• This link (weather) may be helpful longer-term for spectators.  This is model-only data and thus less reliable generally than human forecasts, but it can still be interesting as to general trends.

• Orbital just tweeted:
  "#Antares Ground level wind data indicates gusts are consistently between 15 and 20
  knots - averaging around 18 knots."
  and
  "Peak gust in the last hour was 23 knots - looked like a rare occurrence in the hour. #Antares".

  NASA TV HD on ustream is offline for me. Any alternative to watch the launch on the web in HD?
