will be attached using Velcro. Manufacturer: Oceaneering International (David Clark Company as subcontractor) Function: Terrestrial Extra-vehicular activity (EVA) Operating Pressure: Primary Life Support: 150 hours Other items Like the Shuttle/ISS EMU and the ACES pressure suit, astronauts would've worn, 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 communication 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. Contractor The Constellation Space Suit would be manufactured by Oceaneering International of Houston, Texas. The David Clark Company of Worcester, Massachusetts, the manufacturer of the ACES pressure suit (as well as the manufacturer of the Gemini space suit), and United Space Alliance, would be two of the seven subcontractors used by Oceaneering to develop and manufacture the suit.
