Other Items
Like the Shuttle/ISS EMU and the ACES pressure suit, astronauts will wear, underneath of the suit, a "Depends"-like undergarment known as a Maximum Absorbency Garment or "MAG," which will allow for containment of urine and fecal matter (although the latter may be staved off with a low residue diet), over which a Liquid Cooling and Ventilation Garment (LCVG) is worn. The LCVG, resembling a union suit, has tubing sewn into the material to allow for the circulation of cooling water and removal of carbon dioxide while the suit is worn. A communications cap, known throughout NASA as a "Snoopy cap," is worn by the astronaut to facilitate communication through either the intercom system, or with Mission Control in Houston. Unlike the familiar white-striped brown caps currently in use, the "Snoopy caps" proposed for Constellation will be the white-colored caps worn by all Space Shuttle crews prior to STS-107 and with the two colors of the suit systems (orange and white), will make the American crews to somewhat resemble Soviet cosmonauts of the 1960s.

Famous quotes containing the word items:
“In ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness—a color, a weight, a texture—that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions.”
—Jacques Barzun (b. 1907)
“The best way to teach a child restraint and generosity is to be a model of those qualities yourself. If your child sees that you want a particular item but refrain from buying it, either because it isn’t practical or because you can’t afford it, he will begin to understand restraint. Likewise, if you donate books or clothing to charity, take him with you to distribute the items to teach him about generosity.”
—Lawrence Balter (20th century)
