Project Mercury – Part 2 – Atlas

Part 1 can be found here

The Project Mercury continued with 4 manned orbital flights using the Atlas as the booster. The Redstone was not powerful enough to place a man into orbit and NASA choose the Atlas (America’s first ICBM) to do the job. The Mercury capsule had been designed to be a replacement for the Atlas payload.

Here are the specifications on the Mercury Atlas

Total length 25.0 m
Core diameter 3.1 m
Liftoff mass 116,100 kg
Payload to 185-km low Earth orbit 1,360 kg
Total thrust
boosters (2) 1,600,000 N each
sustainer 280,000 N
verniers (2) 8,800 N each

You can start to build your own Mercury Atlas. There are two paper model links located in my Ultimate Paper Rocket Guide. One is Surfduke’s and the other is available using the Internet Archives to go to Precision Paper Space Model’s Atlas 6.

Sheri’s Hot Rocket’s has a 1/24 scale model available!
