I just received word that the launch of Atlantis to service Hubble has been delayed from October 10 to October 14. The nominal launch time will be 10:19 p.m. Eastern (US) time. The launch was delayed so that NASA could check out all the facilities after Hurricane Ike.
This also means that the launch of Endeavour has been delayed to November 16.
