1963.04.30 - Improvements to the Mercury pressure suit for Mercury MA-9


A number of improvements had been made to the Mercury pressure suit for the Mercury-Atlas 9 (MA-9) flight.

These included a mechanical seal for the helmet, new gloves with an improved inner-liner and link netting between the inner and outer fabrics at the wrist, and an increased mobility torso section. The MA-9 boots were integrated with the suit to provide additional comfort for the longer mission, to reduce weight, and to provide an easier and shorter donning time. Another change relocated the life vest from the center of the chest to a pocket on the lower left leg. This modification removed the bulkiness from the front of the suit and provided for more comfort during the flight. These are but a few of the changes.
