The weather forecast for tomorrow evening's launch window has improved, now
predicting an 80 percent chance of acceptable conditions.

The launch window opens at 6:27 p.m. EDT (2227 GMT) and extends
two-and-a-half hours. That enables SpaceX at least two opportunities to
launch if a problem forces an abort late in the countdown, allowing
sufficient time to recycle and reload super-chilled propellants, officials
said.

The primary concerns Thursday will be the cumulus cloud and thick cloud
weather rules, according to the official U.S. Air Force weather forecast
released this morning.

The outlook calls for a few clouds at 3,000 feet and scattered clouds at
28,000 feet, southeast winds of 10 to 15 mph, and a temperature of 75
degrees Fahrenheit at launch time.

If the launch is delayed to Friday, the weather will worsen with showers,
isolated thunderstorms and gusty winds in the forecast. The forecast for
Friday predicts a 40 percent chance of good weather for a launch.

>
> SpaceX tweeted that the static fire test was completed successfully.
> Engineers will review data from the launch rehearsal before convening a

> two-and-a-half hours.
>
> The static fire test was set for Sunday, followed by a launch attempt
> Wednesday, but preparations ran behind schedule over the weekend.
>
> The launch is critical for SpaceX, which intends to re-fly its rockets
> many times in a cost-cutting measure meant to reduce launch prices and open
> more opportunities for space transportation and exploration.
