The image shows an Air Force pilot, clad in a pressurized suit and helmet, maneuvering the aircraft as the balloon passes below.

They also wear a hooded pressurized suit, fully zipped, that is connected at the small of their back to a hose that pumps in HEPA-filtered air drawn from outside the building.

While these improvements will allow astronauts to hopefully work with less discomfort and more mobility, working in a spacesuit designed for extravehicular activity is still a challenge, as it is a pressurized suit in an extreme and difficult environment.

The Mercury suits developed for flights in the 1960s were modeled after the suits worn by military pilots after World War II. The pilots were beginning to fly at higher altitudes and needed a pressurized suit that could keep oxygen flowing and protect the pilots in the case of a high-altitude ejection.

In 1980, Earle descended 1,250 feet underwater for the deepest dive made without a tether when she walked on the ocean floor off Oahu in a pressurized suit called Jim.
