Currently the crews of the Shuttle wear the Advanced Crew Escape Suit, called “the pumpkin” for its color.
It is used during take-off and landing to ensure the integrity of the crew. In addition to having breathing and pressurization systems, it is equipped with a parachute that in case of emergency allows the astronauts to leave the aircraft from the safety porthole, a life preserver and the most modern communication and location systems.
The helmet serves to protect the astronauts’ head from the vibrations and accelerations to which they are subjected to launch and return. It is equipped with a large visor that allows frontal and lateral vision and a total sunscreen. | NASA
