. @30thSpaceWing: Weather forecast shows a 90% chance of favorable weather for #AtlasV #NROL42 liftoff at 10:30pmPT.

Updated: 09/24/2017 02:40 Weather forecast improves to 90% GO

A check of the current weather shows it is a clear afternoon at Vandenberg and there's a 90 percent chance of favorable conditions at liftoff time for the Atlas 5 rocket from California tonight.

Спойлер

There are no constraints to proceeding with mobile service tower rollback in about an hour. That will reveal the rocket to the elements, allowing the vehicle to be fueled and launched.

The launch time outlook predicts ground fog could hamper visibility a bit. Conditions are expected to include clear skies, patchy ground fog in the area, visibility of 1.5 to 2.5 miles, northerly winds at 5 to 8 knots and a temperature of 51 to 56 degrees F.

The only concern for tonight's launch opportunity is launch visibility due to the fog.

Rollback of the launch pad's service gantry is underway. This is a major milestone in today's countdown, getting the mobile tower retracted to uncover the Atlas 5 rocket.

The structure's internal crane was instrumental in bringing the rocket stages and payload together. And now the fully assembled Atlas 5 is being unveiled for its 73rd launch, the 14th to originate from Vandenberg.
