The 8-million-pound mobile service tower has been retracted from around the Atlas 5 rocket, revealing the 19-story-tall vehicle for liftoff at exactly 9:49:51 a.m. local time today.
The ground crews are getting the gantry's doors closed, plus finishing the final buttoning up of pad equipment before all workers clear the pad for the remainder of the countdown.

The gantry has been secured in its launch position with the doors closed.

Identification of NROL-79 as NOSS was possible given the mission's launch site, vehicle and unique ascent path into a characteristic orbit.

The first two NOSS generations flew in triplet formation to triangulate a ship's position, the 3rd generation uses pairs of satellites.

Introduced in 1976, NOSS is used to track the position of foreign ships and aircraft through their radio signals.

NROL-79 is the eighth mission in support of the third generation of the Naval Ocean Surveillance Satellite Program. http://bit.ly/2lSNdSo

Identifying the classified NROL-79 Satellite

...
The newer satellites entered orbits around 1,000 by 1,200km, 63.4° to avoid a phenomenon discovered during the initial operations of NOSS – a gradual increase in orbital eccentricity due to perturbations caused by Earth's gravitational field. The new setup, as detailed by satellite tracker Ted Molczan, launches the satellites into an orbit with an argument of perigee near 180 degrees. The argument of perigee shifts gradually to 90 degrees and with that, the orbit becomes circular at 1,100 Kilometers around four years after launch. The orbital precession then continues and the orbit becomes elliptical again, reaching 1,000 by 1,200 km again after eight years, likely the operational life of the satellites.

Workers are leaving the pad area in advance of today's propellant loading and launch of the Atlas 5 rocket.

03/01 17:31
In the pre-fueling weather update, conditions remain ideal at Vandenberg for a rocket launch this morning. Skies are clear, winds are light and visibility is good. Air Force meteorologists give a 100 percent chance of favorable weather at the 9:49:51 a.m. launch time (12:49:51 p.m. EST; 1749:51 GMT).
