Samantha Cristoforetti demonstrating the use of the Valsalva device in the Sokol space suit. The Valsalva device is a device used in spacesuits, some full face diving masks, and diving helmets to allow astronauts and commercial divers to equalize the pressure in their ears by performing the Valsalva maneuver inside the suit without using their hands to block their nose.
The image shows the complete multi-layer suit and positive-pressure helmet, lacking only the backpack. (taken c. 1971) A mechanical counterpressure (MCP) suit, partial pressure suit, direct compression suit, or space activity suit (SAS) is an experimental spacesuit which applies stable pressure against the skin by means of skintight elastic ...
The E.M.U Display and Control Module (DCM). The EMU, like the Apollo/Skylab A7L spacesuit, was the result of 21 years of research and development. [Note 1] It consists of a Space Suit Assembly (SSA) assembly which includes the Hard Upper Torso (HUT), arm sections, gloves, an Apollo-style "bubble" helmet, the Extravehicular Visor Assembly (EVVA), and a soft Lower Torso Assembly (LTA ...
The Videosphere is a JVC CRT television that was shaped in the form of a space helmet. It was first introduced in 1970 and was sold up until the early 1980s. It was popular for its modern design; the alarm clock base was an option, most units have a plain base. Videospheres were produced in large quantities in white, red, black, orange and grey.
G5C spacesuit. For the 14-day Gemini 7 mission, both Frank Borman and Jim Lovell wore modified G3C suits, but incorporating several changes: . Replacement of the pressure helmet and neck ring with a zippered hood incorporating a clear, fixed polycarbonate visor, with the astronauts wearing modified Navy-style aviator crash helmets that incorporated the communication equipment (microphones and ...
John Glenn in Mercury suit with helmet. When NASA began the Mercury Project in 1958, one of the first needs was a "space suit": a pressure suit to protect the astronaut in the event of a sudden depressurization of the cabin in the vacuum of space. NASA tested both the Navy Mark IV suit and the X-15 high-altitude suit, and chose the Mark IV ...
The helmet visor used three layers of glass: one unbreakable, one with an ultraviolet filter, and an opaque infrared exterior. All three layers had an anti-fog treatment. Herrera included an electric heater in the suit, but during tests in a chamber simulating high altitudes it turned out that the suit was heated to 33 °C while the temperature ...
The first full-pressure suits for use at extreme altitudes were designed by individual inventors as early as the 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961. Since then space suits have been worn beside in Earth orbit, en-route and on the surface of the Moon.
