1.  Canadian Jim Chamberlin played a major role in the final design of Mercury. This sketch of the Mercury spacecraft is the exact rendition of the one in which John Glenn orbited the earth on February 20, 1962 � just three years to the day after the Avro Arrow cancellation.

Viewed left, the Gemini spacecraft was much more than an enlarged Mercury. Though the two-man crew was still crowded inside a small cabin, much of their equipment was located in a two-part Adapter Module attached to the rear of the Re-Entry Module. Four solid rocket motors were housed in the Retrograde Section, while oxygen, propellants (for the thrusters) and fuel cells (for electricity) were housed in the Equipment Section. The astronauts sat side-by-side, each man having his own hatch and a forward-looking window. [Caption and photo, courtesy NASA via William Mellberg]
