 Atlas2 - Summary
The Atlas II family, which includes the Atlas II, IIA and IIAS, was developed in the mid-1980's to address the growing demand for large commercial geosynchronous satellites.

 ROCKETS
The Atlas launch vehicle is composed of three basic families: the Atlas II (IIA and IIAS), the Atlas III (IIIA and IIIB) and the Atlas V (400 and 500 series).
The Atlas II family is capable of lifting payloads ranging in mass from 6,200 lb (2,812 kg) to 8,200 lb (3,719 kg) to geosynchronous transfer orbit (GTO).
Atlas V results from the culmination of Lockheed Martin's desire to employ the best practices from both the Atlas and Titan programs into an evolved and highly competitive commercial and government launch system for the 21st Century.

 Atlas   (Site not responding. Last check: 2007-10-09)
The Atlas structure in fact was not strong enough to support the weight of propellant and payload; the interior of the Atlas had to be pressurized to prevent the rocket from crumpling under gravity.
It was an Atlas A, one of six slightly different types A, B, C, D, E, and F. The Atlas A suffered a failure of its structure soon after liftoff, causing it to collapse and explode.
Atlas II is available in several versions: the standard Atlas II (6,500 pounds or 2,900 kg to geosynchronous transfer orbit/GTO); the Atlas IIA with upgraded second stage (6,760 pounds or 3,070 kg to GTO); and the Atlas IIAS with four solid rocket boosters (8,200 pounds or 3,720 kg to GTO).

 1st Atlas Launch of Year is Record-Setting 75th Atlas Success in a Row
Since 1962, 145 Atlas vehicles have been launched from Complex 36 - 69 from Pad A and 76 from Pad B. Operations were run from a “blockhouse” that dates back to the 1960s, but with electronic systems that were upgraded along with the rockets.
Atlas III was developed to bridge the technical and operational differences between Atlas IIAS and Atlas V. In reality, today’s mission is the 10th successful launch of the next-generation Atlas family of Atlas III and Atlas V, which combine the best - RD-180 propulsion with the Centaur upper stage.

 Lockheed Martin’s First Atlas V Rocket Stacked Vertically On New West Coast Launch Pad
BOS operations began with stacking the booster followed by erection of the two interstage adapters, the stretched 38.5 feet-tall- (11.68 meters) Centaur upper stage, and the “boat tail,” which is the segment between the vehicle and the payload fairing.
BOS operations took four days to complete, which is standard for Atlas V. Completion of BOS kicks off a period of further test and validation called “pathfinding” to ensure that the team, the vehicle and the facilities are prepared for the first launch.
Atlas V at Vandenberg SLC-3E will use a stationary launch pad with mobile service tower, in contrast to the facilities at Cape Canaveral Air Force Station, where the rocket is stacked in a Vertical Integration Facility and then rolled to the launch pad only 12 hours before launch.
