Here is my first self-designed model, a chimpanzee flight couch which was used in 1961 for the first Mercury Redstone flight with a living being: Ham the Chimpanzee. Since I couldn´t find any sources with exact sizes I ‘designed’ the model just by using photos. History: Mercury Redstone 2 (MR-2) was a rocket mission, launched at 16:55 UTC on January 31, 1961 from LC-5 at Cape Canaveral, Florida. Mercury spacecraft no 5 carried Ham the chimp as a passenger on a suborbital space flight launched on Redstone MRLV-2. The Mercury-Redstone 2 flight tested the rocket and capsule, as well as the ability to work in space and return safely to Earth. Once the rocket and capsule design features selected for the Mercury missions were performing reliably, a chimpanzee named Ham was chosen from a colony of six "astrochimps" to test the environmental control systems inside the Mercury capsule. Researchers sent chimpanzees into space because chimps' organ and skeletal structures are similar to ours, and chimps can be trained. Ham was 3 years 8 months old at launch. After his spaceflight he retired to the National Zoo in Washington, D.C. for 17 years and then in 1981 was moved to a zoo in North Carolina to live with a colony of other chimps. He died on January 19, 1983, at the age 25. The display photo shows the flight couch, a Delta7 Mercury capsule and Ton Notebooms Mercury capsule with escape tower.Actually the model sheets are in word format. I tried to change it to pdf format to make it public here (using free pdf), but I was not successful. Can someone support me ?
