Dawn Launch Moves to No Earlier Than Monday, July 9

The launch of NASA’s Dawn spacecraft aboard a United Launch Alliance Delta II rocket has been postponed to no earlier than Monday, July 9. Due to difficulties with a downrange telemetry aircraft and the availability of a tracking ship, a launch attempt cannot be made before that time.

Also, the weather forecast for the loading of propellants aboard the Delta II second stage indicated the possibility of not being able to complete the operation today.

If the launch occurs on Monday, the launch window is 3:56 to 4:25 p.m. EDT. The launch weather forecast calls for a 40-percent chance of not meeting the launch weather criteria on Monday.

Based on a Monday launch, the prelaunch press conference will be held at 1 p.m. on Sunday, July 8, at the NASA Kennedy Space Center press site.

The NASA News Center codaphone will be updated with any changes to the status and may be dialed at 321-867-2525.
