Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Atlas Ii shopping experience:
1. Compare - without doubt the biggest advantage that the Atlas Ii offers shoppers today is the ability to compare thousands of Atlas Ii at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Atlas Ii? Wrong! If the Atlas Ii is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Atlas Ii then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Atlas Ii? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Atlas Ii and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Atlas Ii wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Atlas Ii then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Atlas Ii site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Atlas Ii, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Atlas Ii, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Atlas II was a member of the
Atlas (rocket family) family of launch vehicles, which evolved from the successful
Atlas missile program of the 1950s. Atlas II was the last Atlas to use a three engine, "stage-and-a-half" design: two of its three engines were jettisoned during ascent, but its fuel tanks and other structural elements were retained. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Altas II, IIA and IIAS models were carried out between 1988 and 2004. (The larger Atlas III was used between 2000 and 2005, and the Atlas V is still in use.)
Features
Atlas II provides higher performance than the earlier Atlas I by using engines with greater thrust and longer fuel tanks for both stages. The total thrust capability of the Atlas II of 490,000 pounds force (2,200 kN) enables the booster to lift payloads of 6,100 pounds (2,767 kg) in geosynchronous orbit of 22,000 miles (35,000 km) or more. This series uses an improved Centaur (rocket stage) – the world’s first high-energy propellant stage – to increase its payload capability. Atlas II also has lower-cost electronics, an improved flight computer and longer propellant tanks than its predecessor, Atlas I.
The most powerful derivative is the Atlas IIAS.
Background
Atlas IIs are launched from
Cape Canaveral Air Force Station, Fla., by the 45th Space Wing. The final West Coast Atlas II launch was accomplished December 2003 by the 30th Space Wing, Vandenberg AFB, Calif.
The Atlas was originally fielded as an ICBM in the late 1950s. On Oct. 31, 1959, the first Atlas, a D model stored horizontally, was placed on alert at Vandenberg AFB by the 576th Strategic Missile Squadron. Atlas E and F models were the first ICBMs to be stored vertically in underground silos and raised by elevators to an above-ground position for launch. The Air Force replaced the Atlas ICBMs with Titan ICBMs and converted the E and F models into space launch vehicles in the late 1960s. The last refurbished Atlas vehicle was launched from Vandenberg AFB in 1995 carrying a satellite for the Defense Meteorological Satellite Program.
NASA used the Atlas as a space launch vehicle as early as 1958. Atlas served as the launch vehicle for
Project SCORE, an instrumentation package developed by the U.S. Army Signal Corps that became the world’s first
communications satellite. The satellite broadcast President Eisenhower’s pre-recorded Christmas message around the world.
An Atlas booster carried astronaut John Glenn into orbit under Project Mercury, the first US manned space program. Atlas Centaur vehicles also launched Mariner and Pioneer planetary probes.
In May 1988, the Air Force chose General Dynamics (now Lockheed-Martin) to develop the Atlas II vehicle, primarily to launch
Defense Satellite Communications System payloads and for commercial users as a result of Atlas I launch failures in the late 1980s.
