Krechet Spacesuit
Krechet lunar space suit as displayed at NPO Zvezda. As in the Orlan suit still used on Mir, the cosmonaut entered the suit by swinging open a hatch at the rear. The backpack containing the life support system was housed in the backpack which made up the hatch door. As in Apollo, the gold-coated outer visor of the helmet reflected ultra-violet radiation. The integrated Kretchet design meant that no external hoses were required as in the American Apollo suit.

Russian space suit, tested 1969. The Krechet spacesuit was designed by the Zvezda OKB for use on the lunar surface. It consisted of flexible limbs attached to a one-piece rigid body / helmet unit.

Status: tested 1969.

The suit was entered through a hatch in the rear of the torso. The exterior of the hatch housed the life support equipment. Maximum operation time was ten hours.

As in the Orlan suit still used on Mir, the cosmonaut entered the suit by swinging open a hatch in the hard abdomen of the suit at the rear. The backpack containing the life support system was integrated with the hatch. As in Apollo, the gold-coated outer visor of the helmet reflected ultra-violet radiation. The integrated Kretchet design meant that no external hoses were required as in the American Apollo suit.

Numerous tests were conducted to determine the best hatch and ladder configuration for the cosmonaut in the bulky Kretchet spacesuit. It was found the standard Soyuz hatch had to be replaced by a customized oval hatch.
