But the new design makes it impossible to carry on one particular ritual launched by the first man in space Yuri Gagarin, who had to stop and relieve himself on the back wheel of the bus that was taking him to the launch pad in 1961..."I'm not sure how they will be able to [carry on the tradition], since we haven't designed the fly," Zvezda director Sergei Pozdnyakov said.
The bright orange Sokol-M suit sports one diagonal zipper, rather than the currently used white Sokol-K, which has a V-shaped opening pointing to the crotch area.
The new suit is lighter due to the zipper and all seams being airtight, so there is no longer a need for the internal rubberised layer known as "the bladder" which is difficult to get in and out of.
