Yesterday the Atlas V carrying the US Navy’s MUOS-1 communications satellite made the 650 yard trip from the Vertical Integration Facility back out to the launch pad again. The rocket is now safely installed on Launch Pad 41 waiting for the countdown clock to start in about 5 hours time.
Assuming things go to plan lift-off will take place at 5:15pm EST (10:15 GMT) with a 44 minute window should the opening not prove favourable for any reason.
The weather forecast has improved and the weather officer is now predicting a 60% chance of favourable conditions during the launch window.
